Description

The HT48RA3/HT48CA3 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications. The data ROM can be used to store remote control codes. The mask version HT48CA3 is fully pin and functionally compatible with the OTP version device.

The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, watchdog timer, programmable frequency divider, HALT and wake-up functions, as well as low cost, enhance the versatility of these devices HT48RA3 to suit a wide range of application possibilities such as industrial control, consumer products, subsystem controllers, and particularly suitable for use in products such as universal remote controller (URC).
