Holtek HT48RA0-2/HT48CA0-2 Remote Control 8-bit Microcontroller Datasheet
The HT48RA0-2 (OTP version) and HT48CA0-2 (mask version) are high‑performance 8‑bit RISC microcontrollers designed for applications that require many I/O pins, low power consumption and flexible timing features. They include a carrier‑wave output, watchdog timer, low‑voltage reset and a built‑in oscillator.
The document provides a full pin diagram, electrical characteristics, memory organization, status register description, oscillator selection (crystal or RC), watchdog timer operation, and package dimensions for the 20‑pin SOP/SSOP package. This manual is written in Chinese.
