HT82A520R/HT82A620R -- Full speed USB 8bit OTP MCU with SPI
(限用產品)

General Description

The HT82A520R/HT82A620R are 8-bit high performance RISC-like microcontrollers designed for USB keyboard mouse and joystick product applications.

The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, Watchdog timer, SPI interfaces, Power Down and wake-up functions, enhance the versatility of these devices to suit a wide range of application possibilities such as sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc.
