7 RESET

The RESET pin (active LOW input) is used to initialize the microcontroller to a defined state. The Reset configuration is shown in Fig.5. Fig.4 External components forRESET pin. andbook, halfpage VSS DDV R ≤ 100 kΩ C RESET MCD174

7.1 Power-on-reset

The Power-on-reset circuit monitors the voltage level of VDD . If VDD remains below the internal reference voltage level Vref (typically 1.3 V), the oscillator is inhibited. When V DD rises above Vref, the oscillator is released and the internal reset is active for a period of td (typically 50 µs). Considering the VDD rise time, the following measures for a correct Power-on-reset can be taken:

• If the VDD rises above the minimum operation voltage before time period td is exceeded, no external components are necessary (see Fig.6).
• If VDD has a slow rise time, such that after the time period (tVref+td) has elapsed the supply voltage is still below the minimum operation voltage (Vmin), external components are required (see Figs 4 and 7). To guarantee a correct reset operation, ensure that the time constant RC≥ 8 × tVDD . A definite Power-on-reset can be realized by applying an (external)RESET signal during power-on.

8 ANALOG CONTROL

8.1 6-bit PWM DACs Five PWM outputs are available for analog control purposes e.g. volume, balance, brightness, saturation, etc. The block diagram of a typical 6-bit PWM DAC is shown in Fig.8. Each PWM output can generate pulses of programmable length that have a repetition frequency of 1⁄64 × fPWM , where fPWM =1⁄3 × fXTAL .

8.1.1 P IN SELECTION FOR PWM OUTPUTS

The PWM outputsPWM1 to PWM5 , share the same pins as theDerivative Port lines DP0.1 to DP0.5. Setting the (relevant PWM enable) bit PWMnE to:

• Logic 1, selects the relevant PWMx output function
• Logic 0, selects the relevant DP0.x Port function.

8.1.2 P OLARITY OF THE PWM OUTPUTS

The polarity of all five PWM outputs is selected by the state of the polarity control bit P6LVL. Setting the control bit P6LVL to:

• Logic 0, sets the PWMx outputs to the default polarity
• Logic 1, inverts all the PWMx outputs.

8.1.3 A NALOG OUTPUT VOLTAGE

A DC voltage proportional to the PWM control setting may be obtained by connecting an integrating network to each of the PWM outputs (see Fig.9). The analog value is calculated as follows: Where:

• PWMDL is the decimal value of the contents of the PWM data latch. Therefore, the analog output voltage is: V A tHIGH tr tHIGH t0 PWMDL× HIGH time of the PWM pulse== tr t0 64× repetition time of the PWM pulse== fXTAL V A PWMDL Fig.8 Block diagram of the 6-bit PWM DAC. handbook, full pagewidth MCD176 DP0.x data I/O DP0.x/PWMx 6-BIT PWM DATA LATCH P6LVL PWMnE 6-BIT DAC PWM CONTROLLER Q Q polarity control bit fPWM

9 VST CONTROL

9.1 14-bit PWM DAC The PCA84C640 has one 14-bit PWM DAC output (TDAC) with a resolution of 16384 levels for Voltage Synthesized Tuning. The PWM DAC (see Fig.10) consists of:

• 14-bit counter
• Two 7-bit DAC interface data latches (VSTH and VSTL)
• One 14-bit DAC data latch (VSTREG)
• Pulse control. The polarity of output TDAC is selected with bit P14LVL. Setting the bit P14LVL to:
• Logic 1, sets the TDAC output to the default polarity
• Logic 0, inverts the TDAC output. 9.1.1 14- BIT COUNTER The counter is continuously running and is clocked by f0. The period of the clock, The repetition time for one complete cycle of the counter: The repetition time for one cycle of the lower 7-bits of the counter is: Therefore, the number of tsub periods in a complete cycle tr is:

9.1.2 D ATA AND INTERFACE LATCHES

In order to ensure correct operation, interface data latch VSTH is loaded first and then interface data latch VSTL. The contents of:

• VSTH are used for coarse adjustment
• VSTL are used for fine adjustment. At the beginning of the first t sub period following the loading of VSTL, both data latches are loaded into data latch VSTREG. After the contents of VSTH and VSTL are latched into VSTREG, one t sub period is needed to generate the appropriate pulse pattern. To ensure correct DAC conversion, two (2) t sub periods should be allowed before beginning the next sequence. fXTAL tr t0 16384×= tsub t0 128×= N t0 16384×

9.2 Coarse adjustment

The coarse adjustment output (OUT1) is reset to LOW (inactive) at the start of each tsub period. It will remain LOW until the time has elapsed and then will go HIGH and remain so until the next t sub period starts.

9.3 Fine adjustment

Fine adjustment is achieved by generating additional pulses at the start of particular sub-periods (tsubn). These additional pulses have a width of t0. The sub-period in which a pulse is added is determined by the contents of VSTL interface latch. Table 3 gives the numbers of the t subn, at the start of which an additional pulse is generated, depending on the bit in VSTL being a logic 0. When more than one bit is a logic 0 a combination of additional pulses are generated. For example, if VSTL = 1111010, which is a combination of

• VSTL = 1111110: sub-period 64, and
• VSTL = 1111011: sub-periods 16, 48, 80 and 112, then additional pulses will be given in sub-periods 16, 48, 64, 80 and 112; this is illustrated in Fig.12. If VSTH = 0011101, VSTL = 1111010 and P14LVL = 0, then the TDAC output is as shown in Fig.13. Table 3 Additional pulse distribution LOWER

10 AFC INPUT

The AFC input is used to measure the level of the Automatic Frequency Control signal. This is achieved by comparing the AFC input signal with the output of a 3-bit DAC as shown in Fig.14. DAC analog switches select one of 8 resistor taps connected between V DD and VSS . Consequently, eight different voltages may be selected (see Table 4). The compare signal AFCC, can be tested to determine whether the AFC input is higher or lower than the DAC level. The AFC input shares the same pin as the Derivative Port line DP1.7. Setting the enable bit AFCE to:

• Logic 1, selects the AFC function
• Logic 0, selects the Derivative Port DP1.7 function.

12 ON SCREEN DISPLAY

12.1 Features

• Display format: 2 rows× 16 characters
• Software controlled vertical and horizontal display position
• 64 different (mask programmable) characters in ROM
• Black box background
• Four programmable display character sizes
• Four programmable character dot matrix sizes: –6 × 9 and 6× 13 –8 × 9 and 8× 13
• Half-dot rounding for the whole screen
• 4 from 7 colours possible on screen
• Clock generator for On Screen Display function with: – RC oscillator – LC oscillator, for the various types of PCA84C44X; 84C64X; 84C84X.

12.2 Horizontal display position control

The horizontal position counter is incremented every OSD cycle after the programmed level of HSYNCN occurs at the HSYNCN pin. The counter is reset when the opposite polarity of the HSYNCN pulse is reached.

12.3 Vertical display position control

The vertical position counter is incremented every HSYNCN cycle and is reset by the VSYNCN signal.

12.4 Clock generator

There are two types of oscillators available for the various types. The oscillator is triggered on the trailing edge of HSYNCN when the OSD logic is enabled and stops on the following leading edge of HSYNCN. The OSD oscillator must be externally adjusted to the desired frequency (decreasing the OSD frequency gives broader characters). Before the oscillation frequency can be adjusted HSYNCN must be HIGH (if HLVL = 1). Oscillation stops by setting the HSYNCN pin LOW when HLVL = 1. 12.4.1 RC OSCILLATOR The RC oscillator is available in the types: PCA84C440; 84C443; 84C640; 84C643; 84C840; 84C843. The external RC network is connected between pin 28 and V SS (see Fig.19).

12.4.2 LC OSCILLATOR

The LC oscillator is available in the types: PCA84C441; 84C444; 84C641; 84C644; 84C841; 84C844. The external LC network is connected between pins 28 and 29 (see Fig.20).

12.7 OSD display position

12.7.1 V ERTICAL POSITION

The line number of the vertical start position for:

• Row 0 is 4× (VP00 → VP05)
• Row 1 is 4× (VP10 → VP15). Where:
• (VP00 → VP05) = the decimal value of VP00→ VP05
• (VP10 → VP15) = the decimal value of VP10→ VP15. The character height in:
• Row 0 is H0 and is a function of the number of dots per character and the state of the size control bits SZ00 and SZ01
• Row 1 is H1 and is a function of the number of dots per character and the state of the size control bits SZ10 and SZ11. Row 0 and Row 1 must not overlap each other and therefore: VP1≥ (VP0 + H0); see Fig.25. The four possible character heights are shown in Table 23. 12.7.2 H ORIZONTAL POSITION The horizontal start position (HP) of,
• Row 0: HP0 = 4× (HP00 → HP05) + 5× tOSCD
• Row 1: HP1 = 4× (HP10 → HP15) + 5× tOSCD Where:
• (HP00 → HP05) = the decimal value of HP00→ HP05 and (HP00→ HP05) > 10
• (HP10 → HP15) = the decimal value of HP10→ HP15 and (HP10→ HP15) > 10
• tOSCD = one OSCD clock period. Therefore for both Row 0 and Row 1, HP0, HP1 ≥ 45 × tOSCD . ROW 0 CHARACTERS VP0 HP0 HP1 VP1 MCD183 ROW 1 CHARACTERS Fig.25 Display position. Fig.26 Background versus no background. handbook, halfpage with background without background MCD182

12.8 OSD character size and colour selection

12.8.1 C HARACTER SIZE

The character sizes are determined by the bits:

• CDTW, for the width
• CDTH, for the height. The character sizes are selected by bits SZn1 and SZn0, which denotes:
• SZ01 and SZ00 for Row 0
• SZ11 and SZ10 for Row 1. Table 23Character sizes selection H denotes one horizontal line, T denotes one OSDC clock period and D denotes dots per character width/height.

12.8.2 C OLOUR SELECTION

Colour selection is achieved using bits in the,

• OSDCA register: CC34, CC24 and CC14
• OSDCB register: CC33, CC23, CC32, CC12, CC21, and CC11
• Display data registers: CC1 and CC0. In this way every combination of four colours can be made (black and white can not be displayed at the same time). The user may choose one colour out of each block. Table 24 shows the selection of the output combinations.

12.9 Character ROM

Character ROM contains the dot character fonts. 13 × 8 dots are reserved for each character, regardless of the dot matrix size actually selected. The dot matrix grid is shown in Fig.28. Philips provides a software under MS DOS environment (IBM/PC or compatible) to help customer to design the character font on the screen and to generate the bit pattern HEX decimal file automatically. Contact your local Philips Sales Organization for details. handbook, halfpage MCD185 12345678 Fig.28 Character ROM.

13 EMULATION MODE

The emulation mode configuration is shown in Fig.29. In the emulation mode configuration the PCA84C640’s CPU is disabled and only its derivative logic is active. The device is controlled by the PCF84C00 bond-out chip. The PCA84C640's two derivative ports act as additional ports for the PCF84C00. The interaction between the two devices is as follows: 1. During the first machine cycle the PCF84C00 fetches an instruction from EPROM and then decodes that instruction. 2. During the second machine cycle the PCF84C00 executes the decoded instruction. If the instruction is related to the derivative ports then DXALE, DXRDN and/or DXWRN become active and the PCA84C640 operates as a peripheral of the PCF84C00. 3. Depending on the type of instruction executed during the second machine cycle the following data transfer happens: a) During TS1 data from the EPROM is available on P0.0 to P0.7 which is then available on IB0.0 of the PCF84C00. b) During TS4 data from the PCA84C640 can be transferred to the PCF84C00. c) During TS6 data from the PCF84C00 can be transferred to the PCA84C640.

19 SOLDERING

19.1 Introduction

There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “IC Package Databook” (order code 9398 652 90011).

19.2 Soldering by dipping or by wave

The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (T stg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.

19.3 Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300°C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400°C, contact may be up to 5 seconds.
