The LC86P4448 uses 256 bytes addressed on FF00H to FFFFH in the program memory as the option configuration data area.
All options of the LC864400 series can be specified.
(2) Option
The option data is written with the option specifying program "SU86K.EXE". The option data is linked to the program area by
the linkage loader "L86K.EXE".
The option is specified by degrees until 3 ms
after going to a 'H' level to the reset terminal.
The program is executed from 00H of the
program counter.
4.5 V to 5.5 V
The program is executed from 00H of the program

(3) ROM space
The LC86P4448 and LC864400 series use 256 bytes addressed on FF00H to FFFFH in the program memory as the option
specified data area. The program memory capacity of this series is, at most, 49152 bytes addressed on 0000H to BFFFH.

How to Use
(1) Create a programming data for LC86P4448
Programming data for EPROM of the LC86P4448 is required.
Debugged evaluation file (EVA file) must be converted to an INTEL-HEX formatted file (HEX file) with the file converter
program EVA2HEX.EXE. The HEX file is used as the programming data for the LC86P4448.
(2) How to program for the PROM
The LC86P4448 can be programmed by the EPROM programmer with attachment W86EP4448D.

• "27010 (Vpp = 12.5 V) Intel high speed programming" mode should be adopted. The address must be set to 13FFFH" and
jumper (DASEC) must be set to 'OFF' at programming.
(3) How to use the data security function
"Data security" is the function to disable the EPROM data from being read out.
The following is the process in order to execute data security function.
1. Set the jumper of attachment 'ON'.
2. Program again. The EPROM programmer will display an error. The error means that the data security functions
normally. It is not trouble of the EPROM programmer or the LSI.
Notes
• Data security is not executed when the data of all addresses have 'FF' at procedure 2 above.
• Data security cannot be executed by programming the sequential operation "BLANK=>PROGRAM=>VERIFY" at
procedure 2 above.
• Set the jumper to 'OFF' after executing the data security.
