(1) Option
The option data is created by the option specified program “SU86K.EXE”. The created option data is linked to the
program area by linkage loader “L86K.EXE” .
(2) ROM space
LC86P7248 and LC8672 00 series use 256 bytes that is addresse d on 0FF00H to 0 FFFFH in the program memory as the
option specified data area. These program memory capacity are 49152 bytes that is addressed on 0000H to 0BFFFH.
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 LC86P7248 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 LC86P7248.
(2) How to program for the PROM
The LC86P7 248 can be prog rammed by PROM programmer with attac hment ; W86EP7248Q
• “27512 (Vpp=12.5V) Intel high speed programming” mode available. The address must be set to “0 to 0FFFFH” and a
jumper (DASEC) must b e 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 PROM programmer displays the error. The error means normally activity of the data security.
It is not a trouble of the PROM 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.
• The QIP packages should be heat-soaked for 12 hours at 125°C immediately prior to mounting (This baking is called
pre-baking).
• After pre-baking, a controlled environment must be maintained until soldering. The environment must be held at a
temperature of 30°C or less and a humidity level of 70% or less. Please solder within 24 hours.

Notice for use
The construction of the one-time programmable microcomputer with a blank built-in PROM makes it impossible for Sanyo to
•
completely factory-test it before shipping. To probe reliability of the programmed devices, the screening procedure shown
in the following figure should always be followed.
It is not possible to perform a writing test on the blank PROM. 100% yield, therefore, cannot be guaranteed.
•
• Keeping the dry packing
The environment must be held at a temperature of 30°C or less and a humidity level of 70% or less.
After openi ng the packing
•
The preparation procedures shown in the following figure should always be followed prior to mounting the packages on the
substrate. Note that the QIP package should be heat-soaked for 12 hours at 125°C immediately prior to mounting (This
baking is called pre-baking). After pre-baking, a controlled environment must be maintained until soldering. The
environment must be held at a temperature of 30°C or less and a humidity level o f 70% or less. Please sold er within 24
hours.
