General Description
The HT48R062/HT48C062 are 8-bit high performance,
RISC architecture microcontroller devices specifically
designed for cost-effective multiple I/O control product
applications. The mask version HT48C062 is fully pin
and functionally compatible with the OTP version
HT48R062 devices.
The advantages of low power consumption, I/O flexibil-
ity, oscillator options, HALT and wake-up functions,
watchdog timer, as well as low cost, enhance the versa-
tility of these devices to suit a wide range of application
possibilities such as industrial control, consumer prod-
ucts, subsystem controllers, etc.
