HT82M75R/HT82M75RE/HT82K75R/HT82K75RE -- I/O Type 8-Bit OTP MCU

General Description

The device is an 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O, mouse/keyboard appliances and SPI control product applications. The advantages of low power consumption, I/O flexibility, Timer functions, Watchdog timer, Power Down, wake-up functions together with the optional peripherals such as EEPROM Memory and RF transceiver provide the devices with versatility for industrial control, consumer products, subsystem controllers, RF module control, etc.
