1. FLASH MEMORY PROGRAMMING Writing to flash memory can be performed without removing the memory from the target system (on board programming). Writing is performed with the dedicated flash programmer (Flashpro III (part No.: FL-PR3 and PG- FP3)) connected to the host machine and the target system. Writing to flash memory can also be performed using flash memory writing adapter connected to Flashpro III. Remark FL-PR3 is a product of Naito Densei Machida Mfg. Co., Ltd.

6.1 Selection of Communication Mode

Writing to a flash memory is performed using Flashpro III in a serial communication. Select one of the communication modes in Tables 6-1 and 6-2. The selection of the communication mode is made by using the format shown in Figure 6-1. Each communication mode is selected by the number of V PP pulses shown in Tables 6-1 and 6-2. Table 6-1.

6.2 Flash Memory Programming Functions

Operations such as writing to flash memory are performed by various command/data transmission and reception operations according to the selected communication mode. Table 6-3 shows major functions of flash memory programming. Table 6-3. Major Functions of Flash Memory Programming Function Description Reset Used to stop write operation and detect transmission cycle. Batch verify Compares the entire memory contents with the input data. Batch erase Erases the entire memory contents. Batch blank check Checks the deletion status of the entire memory. High-speed write Performs write to the flash memory based on the write start address and the number of data to be written (number of bytes). Continuous write Performs continuous write based on the information input with high-speed write operation. Status Used to confirm the current operating mode and operation end. Oscillation frequency setting Sets the frequency of the resonator. Erase time setting Sets the memory erase time. Baud rate setting Sets the communication rate for UART mode I2C mode setting Sets standard/high-speed mode for I 2C bus mode Silicon signature read Outputs the device name and memory capacity, and device block information.

6.3 Connection of Flashpro III

The connection of Flashpro III and the µPD78F0034A or 78F0034AY differs according to the communication mode (3-wire serial I/O, UART, pseudo 3-wire serial I/O, and I 2C bus).

In the start condition, the first clock pulse is generated after this hold time. 2. To fill in the undefined area of the SCL0 falling edge, it is necessary for the device to internally provide at least 300 ns of hold time for the SDA0 signal (which is V IHmin. of the SCL0 signal). 3. If the device does not extend the SCL0 signal low hold time (tLOW), only maximum data hold time tHD:DAT needs to be fulfilled. 4. The high-speed mode I 2C bus is available in a standard mode I 2C bus system. At this time, the conditions described below must be satisfied.

• If the device does not extend the SCL0 signal low state hold time tSU:DAT ≥ 250 ns
• If the device extends the SCL0 signal low state hold time Be sure to transmit the next data bit to the SDA0 line before the SCL0 line is released (tRmax. + tSU:DAT = 1,000 + 250 = 1,250 ns by standard mode I 2C bus specification). 5. Cb: Total capacitance per one bus line (unit: pF)

1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS

Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it.

2 HANDLING OF UNUSED INPUT PINS FOR CMOS

Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices.

3 STATUS BEFORE INITIALIZATION OF MOS DEVICES

Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. Note: Purchase of NEC I 2C components conveys a license under the Philips I 2C Patent Rights to use these components in an I 2C system, provided that the system conforms to the I 2C Standard Specification as defined by Philips.
