(4) Ordering information

1. When ordering the identical mask ROM and PROM devices simultaneously. Provide an EPROM containing the target memory contents together 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) Specification of option

Programming data for PROM of the LC86P6449 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 LC86P6449.

(2) How to program for the PROM

LC86P6449 can be programmed by the EPROM programmer with attachment ; W86EP6448Q.

• Recommended EPROM programmer

Productor EPROM 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 (DASEC) must be set to ‘OFF’ at programming

(3) How to use th e data secur ity 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.
