General Description
The HT48RA0-3/HT48CA0-3 are 8-bit high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for multiple I/O control product
applications. The mask version HT48CA0-3 is fully pin
and functionally compatible with the OTP version
HT48RA0-3 device.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, watchdog timer, HALT and wake-up
functions, as well as low cost, enhance the versatility of
this device to suit a wide range of application possibili-
ties such as industrial control, consumer products, and
particularly suitable for use in products such as infrared
remote controllers and various subsystem controllers.
