The SN8P2501C 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 1K-word OTP ROM, data memory of 48 bytes RAM, one 8-bit timer counters (T0) , one 8-bit counters / timers (TC0), a watchdog timer, three interrupt sources (T0, TC0, INT0), one channel PWM (PWM0), and 4-level stack buffers. There are two oscillator configurations for generating system clock, an internal 16MHz RC oscillator for system clock and includes an internal low frequency RC oscillator for slow mode controlled by programming.

OTP ROM size: 1K * 16 bits

  • RAM size: 48 * 8 bits

  • 4-levels stack buffer

  • Bi-directional I/O: P0, P1, P2, P5

  • Internal pull-up resistor: P0, P1, P2, P5

  • Programmable open-drain: P1.0

  • Level trigger wakeup input port: P0, P1

  • 1 external interrupt: P0.0 (INT0)

  • 2 internal interrupts: T0, TC0

  • 8-bit timer: T0

  • 8-bit counter / timer, programmable PWM: TC0

  • On-chip watchdog

  • Internal High Clock: 16MHz RC oscillator

  • Internal Low Clock: RC oscillator, about 16KHz at 3V, 32KHz at 5V

  • Low power option for power-saving

  • One clock per instruction cycle

  • Most of instructions are one cycle only

  • All ROM area lookup table function(MOVC)
