HT46C232 - Holtek Semiconductor

HT46C232 A/D Type 8-Bit MCU

The HT46R232/HT46C232 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 HT46C232 is fully pin and functionally compatible with the OTP version HT46R232 device. The advantages of low power consumption, I/O fle.
