SH69P842 is a 4-bit microcontroller based on SH6610D, with 2K X 16-bit OTPROM, 123 X 4-bit RAM, 35 system control registers and 88 data registers.
The SH69P842 is a CMOS 4‑bit microcontroller that integrates a SH6610D CPU core, RAM, OTP ROM, timers, PWM, comparators and multiple oscillator options. It is intended for small‑scale controllers and similar applications.
The manual provides detailed information on pin assignments, register maps, initial reset values, oscillator frequency ranges, voltage specifications, and package dimensions for the 8‑pin DIP/SOP/TSSOP versions. This manual is written in Chinese.
| OTP ROM size | 2K × 16 bits |
|---|---|
| RAM size | 123 × 4 bits |
| Oscillator frequency range (external) | 30 kHz – 10 MHz |
| Oscillator frequency range (internal RC) | 4 MHz ±2 % |
| Operating voltage (Vpp) | 2.4 V – 5.5 V |
| Package type | 8‑pin DIP / SOP / TSSOP |
The external oscillator can operate from 30 kHz up to 10 MHz.
All input ports have built‑in pull‑up resistors except PORTA.3.
The device provides one (6+2)‑bit PWM output channel.
After reset the program counter (PC) is set to address $000.
