General Description
The HT48R05A-1/HT48C05, HT48R06A-1/HT48C06
and HT48R08A-1 are 8-bit high performance, RISC ar-
chitecture microcontroller devices specifically designed
for cost-effective multiple I/O control product applica-
tions. The mask version HT48C05 and HT48C06 are
fully pin and functionally compatible with the OTP ver-
sion 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.
