The SN8P2604A is a RISC-like high performance, 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,
TC1), a watchdog timer, four interrupt sources (T0, TC1, INT0, INT1), one channel
8-bit PWM/Buzzer output (PWM1/BZ1), and 8-level stack buffers. There are four oscillator
configurations to select for generating system clock including external High/Low Speed
crystal, ceramic resonator or internal cost-saving RC for system clock, and an internal
low frequency RC oscillator for slow mode controlled by programming.
