General Description
The HT48CA0 is an 8-bit high performance
RISC-like microcontroller specifically designed
for multiple I/O product applications. The de-
vice is particularly suitable for use in products
such as remote controllers, fan/light control-
lers, washing machine controllers, scales, toys
and various subsystem controllers. A halt fea-
ture is included to reduce power consumption.
