General Description
The HT48RA0-1/HT48CA0-1 are 8-bit high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for multiple I/O control product
applications. The mask version HT48CA0-1 is fully pin
and functionally compatible with the OTP version
HT48RA0-1 device.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, watchdog timer,
HALT and wake-up functions, as well as low cost, en-
hance the versatility of this device to suit a wide range of
application possibilities such as industrial control, con-
sumer products, and particularly suitable for use in
products such as infrared remote controllers and vari-
ous subsystem controllers.
