(4) Ordering information
1. When ordering the identical mask ROM and PROM devices simultaneously.
Provide an EPROM containing the tar get memory contents tog ether with the separate order forms for
each of the mask ROM and PROM versions.
2. When ordering a PROM device.
Provide an EPROM containing the target memory contents together with an order form.
How to use
(1) Create a programming data for LC86P5420
Programming data for EPROM of the LC86P5420 is required.
Debugged ev aluation file (EVA f ile) must be conv erted to an INTEL-HEX formatted file (HEX file) with f ile
converter program, EVA2HEX.EXE. The HEX file is used as the programming data for the LC86P5420.
(2) How to program for the EPROM
The LC86P5420 can be programmed by the EPROM programmer with attachment ; W86EP5420D,
W86EP5420Q.

(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 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 a 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.
