General Description
The HT48C10/48C30/48C50/48C70 are 8-bit
high performance RISC-like microcontrollers,
specifically designed for multiple I/O product
applications. These devices are suitable for use
in products such as remote controllers, fan/light
controllers, washing machine controllers,
scales, toys, and various subsystem controllers.
They all contain a halt feature to reduce power
consumption. The major differences between
these microcontrollers are attributed to vari-
ations in sizes of the ROM and RAM, as well as
bit number, counter number, I/O line number,
and different level subroutine nesting. Roughly
speaking, the HT48C10 is a microcontroller
with most economic features and the HT48C70
is one with the most features of the four micro-
controllers.
