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.
