HT48RA0-3/HT48CA0-3 -- Remote Type 8-Bit MCU (Restricted Products)

General Description

The HT48RA0-3/HT48CA0-3 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. The mask version HT48CA0-3 is fully pin and functionally compatible with the OTP version HT48RA0-3 device.

The advantages of low power consumption, I/O flexibility, timer functions, watchdog timer, HALT and wake-up functions, as well as low cost, enhance the versatility of this device to suit a wide range of application possibilities such as industrial control, consumer products, and particularly suitable for use in products such as infrared remote controllers and various subsystem controllers.
