General Description
The HT48R07A-1 is an 8-bit high performance, RISC
architecture microcontroller devices specifically de-
signed for cost-effective multiple I/O control product ap-
plications.
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.
