General Description

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 compati-

ble with the OTP version HT46R232 device.

The advantages of low power consumption, I/O flexibil-

ity, programmable frequency divider, timer functions,

oscillator options, multi-channel A/D Converter, Pulse

Width Modulation function, I

2C interface, HALT and

wake-up functions, enhance the versatility of these de-

vices to suit a wide range of A/D application possibilities

such as sensor signal processing, motor driving, indus-

trial control, consumer products, subsystem controllers,

etc.
