SH69P43
Overview
The SH69P43 is an advanced CMOS 4-bit microcontroller. It provides the following standard features: 3K words of OTPROM, 192 nibbles of RAM, 8-bit timer/counter, 8-bit A/D converter, 10-bit high speed PWM output, on-chip oscillator clock circuitry, on-chip watchdog timer, low voltage reset function and supports power saving modes to reduce power consumption.
