SC65D02C40
8-BIT MCU FOR REMOTE CONTROLLER(40K ROM)
DESCRIPTION
SC65D02C40 is a multifunction infrared remote controller
integrating many electrical appliances and many code formats
(do not support LCD display).
This chip is based on 8-bit MCU SC65X designed by Silan
company. It provides built-in 8K program memory and 32K
data memory.
Its assistant PC design software can produce the required
remote controller data which need to mask to ROM by set the
code formats and input the initial data automatically, thus
reduce the design cycle and improve the reliability and
efficiency.
SOP-24-375-1.27 SSOP-24-300-0.65
SOP-28-375-1.27 SSOP-28-300-0.65
FEATURES
* Built-in hundreds of different code formats for remote
controllers and it can control many household
applications.
* Single chip which composes the system only need a few
components.
* CMOS technology, operating voltage is 2.0V-3.6V and the
quiescent power dissipation is less than 2uA.
* SC65X main processor, built-in 8K ROM and 32K ROM.
* Provide independent hardware code sending module,
carrier frequency and duty can be set flexibly. (the carrier
frequency range is 17.2K-188K)
* The pins used for keypress function are 16 at most, and it
can support 64 keys.
* External 4MHZ crystal oscillator. The operating frequency
of hardware code sending module is 4MHZ, and the
operating frequency of the other parts (including MCU) is
1MHz.
* Provide well software as well as good reliability and
development period is short.

I/O Descriptions
R/W Bit[1: 0]: WDT frequency pre-dividing set bit; Bit[7: 2]: unused
WDT clear register A combined with Wdt_ClrB to carry out the clear
W
operation.
Bit0: System sleep control bit (when is 1, the system enter SLEEP
W
mode)
R bit0: System sleep, bit1: WDT overflow flag register
R/W Bit[5: 0]: Bit operation control register
WDT clear register B combined with Wdt_ClrA to carry out the clear
W
operation.
Bit1: Oscillator enable control. (Default the oscillator is open after
W
reset, and can be closed by program)
R/W P0 input/output direction control register (1: input; 0: output)
R/W P0 8-bit data register.
R/W P1 input/output direction control register (1: input; 0: output)
R/W P1 8-bit data register.
R/W P2 input/output direction control register (1: input; 0: output)
R/W P2 8-bit data register.
W Key indicator light output control register.
² Wdt_Res: Reset signal when the watch dog overflows.
² The low voltage detection circuit detects the supply voltage in real time. When it is lower than a certain
value, the circuit will still in reset state, thus to avoid the unstable working state.
