HT46R01中文资料10-Pin MSOP A/D Type 8-Bit OTP MCU数据手册Holtek规格书

描述 Description

General Description
The HT46R01/HT46R02/HT46R03 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for a wide range of applications. In addition to providing the usual microcontroller I/O control functions, the fully integrated A/D converter allows the interfacing and processing of external analog signals such as those from sensors.
