The SN8P2743 is a RISC-like high performance and low power consumption 8-bit micro-controller.
The device is designed with the excellent IC structure including the program memory
up to 4K-word OTP ROM, data memory of 128-bytes RAM, two 8-bit timer counters (T0,
TC0), a watchdog timer, seven interrupt sources (T0, TC0, ADC, CM0, CM1, CM2, INT0),
an 8 channel 12-bit ADC converter, one channels 8-bit PWM/Pulse Generator output,
one channels 2K/4K buzzer output, 3 sets comparator function, 1 set OP-AMP and 8-level
stack buffers. There are four oscillator configurations to select for generating system
clock, including High/Low Speed crystal, ceramic resonator or cost-saving RC. This
device also includes an internal 16MHz RC oscillator for system clock and includes
an internal low frequency RC oscillator for slow mode controlled by programming.
