How to use
(1) Create a programming data for LC86E5420
Programming data for EPROM of the LC86E5420 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 LC86E5420.
(2) How to program for the EPROM
The LC86E5420 can be programmed by the EPROM programmer with attachment ; W86EP5420D,
W86EP5420Q.

• "27512 (Vpp=12.5V) Intel high speed programming" mode available. The address must be set to
"0000H to 7FFH" 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 data security.
1. Set 'ON' the jumper of attachment.
2. Program again. Then the 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 sequential operation "BLANK→PROGRAM→VERIFY" cannot be executed data
security at the sequence 2 above.
• Set 'OFF' to the jumper after executing the data security.
(4) How to eliminate
The programming data can be erased by using the EPROM eraser.
(5) Shielding
The UVEPROM (ultraviolet erasable and programmable ROM) is in it. Put the seal on the window in use.
