LC86P6548

No.6690-4/22

How to use

(1) Specification of option

Programming data for PROM of the LC86P6548 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 LC86P6548.

(2) How to program for the PROM

LC86P6548 can be programmed by the EPROM programmer with attachment ; W86EP6548Q.

MODEL 1890A

• “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 PROM.

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 “BLANK

⇒PROGRAM⇒VERIFY” cannot be executed data security at the

sequence 2 above.

• Set to ‘OFF’ the jumper after executing the data security.
