General Description
The HT82A520R/HT82A620R are 8-bit high perfor-
mance RISC-like microcontrollers designed for USB
keyboard mouse and joystick product applications.
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, Watchdog timer, SPI inter-
faces, Power Down and wake-up functions, enhance
the versatility of these devices to suit a wide range of ap-
plication possibilities such as sensor signal processing,
motor driving, industrial control, consumer products,
subsystem controllers, etc.
