HT46R321

A/D Type 8-Bit OTP MCU with OPA and 8´4 LED Driver

Rev. 1.00

1

August 3, 2007

General Description

The HT46R321 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.
