How to use

(1) Preparation

A complete evaluation (EVA) file must be converted to an INTEL-HEX formatted file (HEX) file for program to the LC86E6548. An EVA2HEX.EXE. can convert a EVA file to a HEX file. Program the file that converted by the EVA2HEX to the LC86E6548.

(2) How to program for the EPROM

LC86E6548 can be programmed by the EPROM programmer with attachment ; W86EP6548Q.

• Recommended EPROM programmer

Productor EEPROM programmer Advantest R4945, R4944, R4943

Andou AF-9704 AVAL PKW-1100, PKW-3000

Minato electronics MODEL 1890A

• “27512 (Vpp=12.5V) Intel high speed programming” mode available. The address must be set to “0 to 0FFFFH” and a jumper (D ASE C) 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 “BLANK⇒PROGRAM⇒VERIFY” cannot be executed data security at the

sequence 2 above.

• Set to ‘OFF’ 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 programmable ROM) is in it. Put the seal on the window in use.
