General Description
The HT46R12A is an 8-bit, high performance, RISC ar-
chitecture microcontroller devices specifically designed
for A/D applications that interface directly to analog sig-
nals, such as those from sensors.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, HALT
and wake-up functions, provide the device with the ver-
satility to meet the requirements of wide range of A/D
application possibilities such as external analog sensor
signal processing.
With the inclusion of two comparators and a fully inte-
grated programmable pulse generator, the device is par-
ticularly suitable for use in products such as induction
cookers and other home appliance application areas.
