General Description
The HT46R343 is 8-bit, high performance, RISC archi-
tecture microcontroller devices. With their fully inte-
grated A/D converter they are especially suitable for
applications which interface to analog signals, such as
those from sensors. The addition of an internal opera-
tional amplifier/comparator and PWM modulation func-
tions further adds to the analog capability 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, LED driver, Power-down and wake-up
functions etc, the application scope of these devices is
broad and encompasses areas such as sensor signal
processing, motor driving, industrial control, consumer
products, subsystem controllers, etc.
