General Description
The HT46RU24 is 8-bit, high performance, RISC archi-
tecture microcontroller devices specifically designed for
A/D applications that interface directly to analog signals,
such as those from sensors.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, Pulse
Width Modulation function, I²C interface, UART bus,
HALT and wake-up functions, enhance the versatility of
these devices to suit a wide range of A/D application
possibilities such as sensor signal processing, motor
driving, industrial control, consumer products, subsys-
tem controllers, etc.
