General Description
The HT46R322 and HT46R342 are 8-bit, high perfor-
mance, RISC architecture microcontroller devices. With
their fully integrated A/D converter they are especially
suitable for applications which interface to analog sig-
nals, such as those from sensors. The addition of an in-
ternal operational amplifier/comparator and PWM
modulation functions further adds to the analog capabil-
ity of these devices.
With the comprehensive features of low power con-
sumption, I/O flexibility, programmable frequency di-
vider, timer functions, oscillator options, multi-channel
A/D Converter OP/Comparator, Pulse Width Modula-
tion function, Power-down and wake-up functions etc,
the application scope of these devices is broad and en-
compasses areas such as sensor signal processing,
motor driving, industrial control, consumer products,
subsystem controllers, etc.
The HT46R342 is under development and will be avail-
able soon.
