General Description
The HT46R53/HT46R54 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.
