SH69P48A
Overview
SH69P48A is a single-chip 4-bit micro-controller, that integrates a SH6610D CPU core, 253 nibbles of RAM, 4K words of OTP ROM, two 8-bit timer/counter, 10 channels 10-bit ADC, 2 channels (8 + 2) bits high speed PWM output, on-chip oscillator clock circuitry, on-chip watchdog timer, low voltage reset function and support power saving modes to reduce power consumption. The SH69P48A is ideal for charger applications. 1 V2.1 SH69P48A.
