The SN8P26L31 Series is a RISC-like high performance and low Operating Voltage 8-bit
micro-controller (1.8V ~ 3.6V@1MIPS). The device is designed with the excellent IC
structure including the program memory up to 8K-word OTP ROM, data memory of 240 bytes
RAM, two 8-bit timer counters (T0, TC1), a watchdog timer, four interrupt sources
(T0, TC1, CMP0, INT1), one channel PWM output (PWM1), one channel comparator, 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, an internal 8MHz RC oscillator for system clock and includes an internal
low frequency RC oscillator for slow mode controlled by programming.
