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, I²C 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.
