General Description

The HT48R70A-1/HT48C70-1 are 8-bit high perfor-

mance, RISC architecture microcontroller devices spe-

cifically designed for multiple I/O control product

applications. The mask version HT48C70-1 is fully pin

and functionally compatible with the OTP version

HT48R70A-1 device.

The advantages of low power consumption, I/O flexibil-

ity, timer functions, oscillator options, HALT and

wake-up functions, watchdog timer, buzzer driver, as

well as low cost, enhance the versatility of these devices

to suit a wide range of application possibilities such as

industrial control, consumer products, subsystem con-

trollers, etc.
