General Description
The HT48R0AA-1 is an 8-bit high performance, RISC
architecture microcontroller devices specifically de-
signed for cost-effective multiple I/O control product ap-
plications.
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 prod-
ucts, subsystem controllers, etc.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator configuration options,
