HT46R01A中文资料合泰数据手册PDF规格书

General Description

The HT46R01A is 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.
