HT82M72E/HT82M72A -- RF One Channel Mouse 8-bit
OTP MCU
General Description
The device is an 8-bit high performance, RISC
architecture microcontroller devices specifically designed for
multiple I/O control product applications. With its internal 27MHz
amplifier the device is suitable for applications such as 27MHz or
2.4GHz keypads etc.
The advantages of low power consumption, I/O
flexibility, timer functions, oscillator options, Power Down and
wake-up functions, Watchdog timer, motor driving, industrial
control, consumer products, subsystem controllers, etc.
