HT46R24中文资料合泰数据手册PDF规格书

General Description

The HT46R24/HT46C24 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for A/D applications that interface directly to analog signals, such as those from sensors. The mask version HT46C24 is fully pin and functionally compatible with the OTP version HT46R24 device.
