SC65D02C40
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 code 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 design, 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.

2. 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 signal for WDT and code transmitting block, at the same
time as the SC65X MCU system clock after dividing frequency by 4.

Where:
Rd is drive resistor, the value is 100Ω~ 300Ω.
C1 and C2 are load capacitors with same value, the range is ：10pF ~ 30pF.
XTAL is crystal oscillator, frequency is 2MHz ~ 6MHz.
3. Periphery modules
3.1 WDT/timer
[Description]
As shown in figure 3, in WDT/timer module, the 16-bit timer 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.

SC65D02C40
[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(ROM), and the address range is 6000H ~FFFFH. The
configuration area FFF0H~FFFFH contains 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 the 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 routine, 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:

The oscillator clock OscClk generates TClk (the cycle is T) via the code transmitting basic clock. The counting
clock of the carrier generator is from the system clock TClk, as shown in figure 8. Where, the high level and low
level time of the carrier is decided by the customer set TX_Carrier, and the unit is T.
Figure 8 – Carrier generation theory
TClk generates high and low level basic unit time TH and TL via basic 0/1 generator. TH and TL are decided by
setting TX_SetBase1 and TX_SetBase0, and unit is T. TH is the basic unit time of high level time, and TL is the
basic unit time of low level time.

Note:
The design precondition of above three typical application circuits is: if the circuit structure is not
changed, the SC65D02C40 can directly take the place of SC65D02P40;
Typical application circuit (a) is generally used in the situation with one LED lamp;
Typical application circuit (b) is generally used in the situation with many LED lamps, if no need to light
all the LEDs, you can use the typical application circuit (c) to save the cost.
