General Description

The HT46R53A/HT46R54A 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 advan-

tages of low power consumption, I/O flexibility, timer

functions, oscillator options, multi-channel A/D con-

verter, Pulse Width Modulation function, HALT and

wake-up functions, watchdog timer, as well as low cost,

enhance the versatility of these devices to suit a wide

range of A/D application possibilities such as sensor

signal processing, chargers, motor driving, industrial

control, consumer products, subsystem controllers, etc.
