8-Bit Microcontroller Series

Holtek Semiconductor 

HT48CXX/HT48RXX

8-Bit Microcontroller Series

Features

• Operating voltage: 2.4V~5.2V

• Bidirectional I/O lines with a selection of 18,

22, 32 and 56 lines

• One interrupt input

• Programmable timer/event counters with

overflow interrupts and a selection of one

8-bit counter, one 8-bit and one 16-bit count-

ers, or two 16-bit counters

• On-chip crystal and RC oscillator

• Watchdog timer

• Program ROM with size selection of

1K×14, 2K×14, 4K×15 and 8K×16 bits

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

• Data RAM with size selection of 64×8, 96×8,

160×8 and 224×8 bits

• Halt function and wake-up feature to reduce

power consumption

• 63 powerful instructions

• Up to 0.5µs instruction cycle with 8MHz

system clock at VDD=5V

• All instructions in 1 or 2 machine cycles

• 14-bit/15-bit/16-bit table read instructions

• 2-level/4-level/8-level subroutine nesting

• Bit manipulation instructions

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.
