LC66E516

4-bit Single Chip Microcontroller with EPROM

Preliminary

Overview

The LC66E516 is a 4-bit single-chip microcontroller with

an EPROM on-chip, and can be used for developing and

evaluating application programs for the LC665XX series

4-bit single-chip microcontrollers.

The LC66E516 microcontroller is a 4-bit single-chip IC

with an EPROM on-chip and brought to you in ceramic

DIC64S package with a window and ceramic QFC64 pack-

age with a window. This window permits the user to erase

EPROM program data as many times as he or she wants.

Then, it could be said that this single-chip IC is best suited

for developing application programs.

The LC66E516 microcontroller has the same function and

the pin assignment as those of the 4-bit single-chip mask

programmed ROM-version LC66E516 microcontroller. The

on-chip EPROM is 16k bytes in size.

LC66558B, LC66562B, LC66566B and that they are listed

in the table on page 18 with a few pieces of information.

• Write/Read operation with an EPROM writer

Used with the dedicated writer board (W66E516DH for

DIC, W66E516QH for QFC), an EPROM writer avail-

able on your local market permits the user to write or read

data to or form the 16KB on-chip EPROM. Please note

that the EPROM writer should be an ADVANTEST prod-

uct or the EVA800/850 accessory writer used for the 27128

type EPROM.

• Pin-compatible with a mask programmed ROM-version

single-chip microcontroller (LC66516B, for example)

• Instruction cycle time:0.92µs to 10µs

• Single +5V power supply (Ta=10°C to 40°C)

Features

• Optional functions user-selectable by speciflying EPROM

option data.

The 56 optional functions on the LC665XX series single-

chip microcontrollers can be selected by writing appro-

priate data to the on-chip EPROM. This function specifi-

cation by the user allows application system to be devel-

oped and tested under the same working environment as

that of production chip. In other words, the same inter-

face circuit functions as those of production chips can be

built up by the user.

Please note that the above-mentioned optional functions

include port output type(open-drain or pull-up), output

pin logic level at reset, watchdog timer selection and the

like.

• On-chip 16KB EPROM

The on-chip EPROM enable the user to develop and evalu-

ate application programs which can be run on every

LC665XX series microcontroller. Please note that the

LC665XX series microcontrollers are LC66506B,

LC66508B, LC66512B, LC66516B, LC66556A,

LC66558A, LC66562A, LC66566A, LC66556B,

Any and all SANYO products described or contained herein do not have specifications that can handle

applications that require extremely high levels of reliability, such as life-support systems, aircraft’s

control systems, or other applications whose failure can be reasonably expected to result in serious

physical and/or material damage. Consult with your SANYO representative nearest you before using

any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that

exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other

parameters) listed in products specifications of any and all SANYO products described or contained

herein.
