General Description
The HT48RU80/HT48CU80 are 8-bit high performance,
RISC architecture microcontroller devices specifically
designed for multiple I/O control product applications.
The mask version HT48CU80 is fully pin and function-
ally compatible with the OTP version HT48RU80 de-
vice.
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.
The HT48CU80 is under development and will be avail-
able soon.
