HT46R24 Datasheet (Holtek Semiconductor)

HT46R24, A/D Type 8-Bit MCU

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
