The SN8PC20 is a RISC-like high performance and low operating voltage 8-bit micro-controller
(1.8V~3.6V @1MIPS). One clock per instruction cycle (1T) architecture will provide
up to 8MIPS computation power. The device is designed with the excellent IC structure
including the program memory up to 2K-word OTP ROM, data memory of 56-bytes RAM, one
8-bit timer counters (T0), a watchdog timer, two interrupt sources (T0, INT0), one
channel duty/cycle programmable IR output (IROUT) with 400mA sunk current and 4-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 8MHz RC oscillator for system clock and includes
an internal low frequency RC oscillator for slow mode controlled by programming.
