The SN8PC22 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 16K-word OTP ROM, data memory of 240-bytes RAM,
two 8-bit timer counters (T0, TC0), a watchdog timer, three interrupt sources (T0,
TC0, INT0), one channel duty/cycle programmable IR output (IROUT) with 400mA sunk
current, IR input receiver circuit, 8-bit capture timer 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 8MHz RC oscillator for system clock and includes an internal low frequency
RC oscillator for slow mode controlled by programming.
