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.

Oscillator circuit
SC65D02C40 provides a high-gain RP-amplifie whose input is X
IN
and output is X
OUT
. By connecting a quartz
crystal and two capacitors between X
IN
and X
OUT,
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.
