HT48R05A-1

8-Bit OTP Microcontroller

Preliminary

Features

Operating voltage:

Halt function and wake-up feature reduce

power consumption

_SYS=4MHz: 3.3V~5.5V

_SYS=8MHz: 4.5V~5.5V

Up to 0.5ms instruction cycle with 8MHz

system clock at V_DD=5V

13 bidirectional I/O lines

An interrupt input shared with an I/O line

8-bit programmable timer/event counter with

overflow interrupt and 8-stage prescaler

On-chip crystal and RC oscillator

Watchdog timer

All instructions in one or two machine cy-

cles

14-bit table read instruction

Two-level subroutine nesting

Bit manipulation instruction

63 powerful instructions

Low voltage reset function

General Description

The device is an 8-bit high performance

RISC-like microcontroller designed for multi-

ple I/O product applications. The device is par-

ticularly suitable for use in products such as

remote controllers, fan/light controllers, wash-

ing machine controllers, scales, toys and vari-

ous subsystem controllers. A halt feature is

included to reduce power consumption.

The program and option memories can be elec-

trically programmed, making the microcontrol-

ler suitable for use in product development.
