General Description
T he 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 c o n t r o l l e r s , 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 variations 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 microcontrollers.
