LC86E6449
8-Bit Single Chip Microcontroller
with the UVEPROM
Preliminary
Overview
The LC86E6449 is a CMOS 8-bit single chip microcontroller with UVEPROM for the LC866400 series.
This microcontroller has the function and the pin description of the LC866400 series mask ROM version, and 48K-byte
EPROM. The program data is rewritable. It is suitable to develop the program.
Features
(1) Option switching by EPROM data
The option function of the LC866400 series can be specified by the EPROM data.
LC86E6449 can be checked the function of the trial pieces using the mass production board.
(2) Internal one-time EPROM capacity : 49408 bytes
(3) Internal RAM capacity
: 1152 bytes
Used EPROM or RAM capacity are equal ROM or RAM capacity of mask ROM version which applies LC86E6449.

LC86E6449
How to use
(1) Specification of option
Programming data for EPROM of the LC86E6449 is required.
Debugged evaluation file (EVA file) must be converted to an INTEL-HEX formatted file (HEX file) with file converter
program, EVA2HEX.EXE. The HEX file is used as the programming data for the LC86E6449.
(2) How to program for the EPROM
LC86E6449 can be programmed by the EPROM programmer with attachment ; W86EP6448Q.

• “27512 (Vpp=12.5V) Intel high speed programming” mode available. The address must be set to “0 to
0FFFFH” and a jumper (DASEC) must be set to ‘OFF’ at programming.
(3) How to use the data security function
“Data security” is the disabled function to read the data of the EPROM.
The following is the process in order to execute the data security.
1. Set ‘ON’ the jumper of attachment.
2. Program again. Then EPROM programmer displays the error. The error means normally activity of the data security.
It is not a trouble of the EPROM programmer or the LSI.
Notes
• Data security is not executed when the data of all address have ‘FFH’ at the sequence 2 above.
• The programming by a sequential operation “BLANKPROGRAMVERIFY” cannot be executed data security at the
sequence 2 above.
• Set to ‘OFF’ the jumper after executing the data security.
