8-BIT MCU FOR PRESET REMOTE CONTROL (MASK TYPE)
DESCRIPTION
SC65D02C40 is a preset universal remote control transmitter which uses Silan’s 8-bit MCU core SC65X. It integrates 40K-byte MASK ROM, memory and special co de transmitting module, so a preset universal remote solution can be easily achieved only with a few periphery components. It can preset hundreds of different remote codes and data to control a plurality of home electric appliances. For universal remote control de sign, PC software auxiliary function is available for reducing design cycle and improving reliability and efficiency through code parameter setting, for which only original data is required to get code data to be masked to ROM. Another universal remote control transmitter SC65D02P40 of Silan has built-in 8K ROM and 32K OTP, and it is compatible with SC65D02C40 in memory total capacity and function. The program developed on SC65D02P40 can be directly used to generate the masking program of SC65D02C40, which can be used foe small- batch production and sample design.

Oscillator circuit SC65D02C40 provides a high-gain RP-amplifie whose input is XIN and output is XOUT. By connecting a quartz crystal and two capacitors between XIN and XOUT, a stable self oscillator can be composed, shown in figure 2. The oscillation waveform generated by the oscillator circuit generates the oscillator clock after it is reshaped by the inverter. The oscillator clock provides the clock si gnal for WDT and code transmitting block, at the same time as the SC65X MCU system clock after dividing frequency by 4. 40K×8 ROM FFF0H 0000H 01A0H 019FH 6000H 5FFFH (Unused) SFR 0000H 0030H 002FH (Unused) 0080H 007FH 256×8 Customer RAM 0180H 017FH 32×8 Code transmitting buffer 019FH FFFFH 6000H 5FFFH (System reserved) Reset vector value Interrupt vector value Reset vector value in test mode Interrupt vector value in test mode (System reserved) FFFFH FFFEH FFFDH FFFCH FFFBH FFFAH FFF9H FFF8H FFF3H FFF2H FFF1H FFF0H FFF7H FFF6H FFF5H FFF4H 0100H 00FFH Zero page memory Figure 1 – Address assignment

3.1 WDT/timer
[Description] As shown in figure 3, in WDT/timer module, the 16-bit ti mer can also be used as the low 16-bit of 21-bit WDT. The counting clock of WDT/timer can be directly provided by oscillator clock OscClk. [Structure] Figure 3 – WDT/timer diagram HANGZHOU SILAN MICROELECTRONICS CO.,LTD REV:1.1 2008.12.10 Http: //www.silan.com.cn Page 6 of 17
[Function description] When external reset occurs, the initial value of timer(WDT_TimerH, WDT_TimerL)and 21-bit watchdog counter are both cleared. When use the clear module to reset the watchdog timer, the high 5-bit of the watchdog counter is cleared, the low 16-bit will be loaded from the initial value register of timer again and begin to count. When the low 16-bit of watchdog counter counts to FFFFH, the timer will overflow if increasing by 1 , then reload the initial value of timer; At this time, if the interrupt mask bit (WDT_MASK)=“0” and the timer interrupt enable bit(WDT_TimerEn)=“1”, it will generate timer interrupt signal, and WDT_FLAG is set. Add 1 to the counting value of high 5-bit of watchdog timer when bit15 of watchdog counter changes from 1 to 0; the watchdog will generate reset signal if bit20 of watchdog counter changes from 1 to 0.
3.2 I/O ports
[Description] SC65D02C40 includes three groups of I/O ports: P0, P1 and P2. P0 and P2 are 8-bit parallel ports, while P1 is 4-bit parallel port. Each I/O port of SC65D02C40 can be set independently as weak pull-up input or push-pull output status. The high level output capacity of the port is much bigger than low level output capacity, so it can identify the dual- key or multi-key pressing at the same time. [Structure] Figure 4 – P0 structure Note: The structure of P1 and P2 is the same as P0. [Function description] As shown in figure 4, we take P0 for example to introduce the I/O port function. The function of P1 and P2 is the same with that of P0. When P0_Ctrl[n] is set, PMOS P1 and NMOS N1 are both off, PMOS P2 is on, pull-up resistor Rpu is active, and port P0n is input mode. When P0_Ctrl[n] is cleared, PMOS P2 is off, port P0n is output mode. At this time, when P0_Data[0] is set, PMOS P1 is on, NMOS N1 is off, and port P0n outputs high level; when P0_Data[0] is cleared, PMOS P1 is off, NMOS N1 is on, and port P0n outputs low level.

3.3 P3 port
[Description] P3 of SC65D02C40 has only one bit which is only as output port.
3.4 ROM
[Description] SC65D02C40 has built-in 40K-byte read-only memory(R OM), and the address range is 6000H ~FFFFH. The configuration area FFF0H~FFFFH cont ains reset and interrupt vectors for normal working mode and test mode.shown in figure 5: Figure 5 – MASK configuration area The reset vector value is the initial value of PC after t he circuit is reset, that is the entry address of the main program, where, the high byte is stored in FFFBH, and low byte is stored in FFFAH. For example: FFFAH stores 40H, FFFBH stores 80H, then after the circuit is reset, then PC points to 8040H. The interrupt vector value is the initial value of PC after MCU responses to the interrupt, which is the entry address of the interrupt service routi ne, where, the high byte is stored in FFF9H, and low byte is stored in FFF8H. For example: FFF8H stores 00H, FFF9H stores 80H, then the interrupt entry address is 8000H. The reset vector value and the interrupt vector value in test mode are useful in production test, and the customer should set FFF0H with 00H, FFF1H with 60H, FFF2H with 04H, FFF3H with 60H to make sure the program down load is correct, for example, the customer should add the following code in proper position: ORG FFF0H DW 6000H DW 6004H HANGZHOU SILAN MICROELECTRONICS CO.,LTD REV:1.1 2008.12.10 Http: //www.silan.com.cn Page 8 of 17
