General Description
The HT48R05A-1/HT48C05 and HT48R06A-1/
HT48C06 are 8-bit high performance, RISC architec-
ture microcontroller devices specifically designed for
cost-effective multiple I/O control product applications.
The mask version HT48C05 and HT48C06 are fully pin
and functionally compatible with the OTP version
HT48R05A-1 and HT48R06A-1 devices.
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.
