• Conditions required for mounting the LC72P366

1. Products programmed by the user:

Mount the LC72P366 using the following procedure

when using products shipped from Sanyo without the

PROM having been programmed.

2. Products programmed by Sanyo:

Mount the LC72P366 using the following procedure

when using products shipped from Sanyo with the

PROM programmed by Sanyo.

[Caution]

• Due to the nature of the product, it is not possible for Sanyo to fully test

one-time programmable PROM microcontrollers (i.e., products with

blank PROMs) before shipment to the customer. This means that there

will be some amount of yield reduction after programming.

LC72P366

Usage Procedures

• Programming the on-chip PROM

There are two methods for writing the LC72P366 on-chip PROM as follows:

— Using a general-purpose PROM programmer

A general-purpose PROM programmer can be used if a special-purpose PROM programming adapter (product

name: LC72P366 EPROM PROGRAMMER) is used. The write procedure used is the 27512 or 27C512 (with Vpp

= 12.5 V) Intel fast write method. Specify 0000H to 7FFFH as the address settings.

— Using the RE32N in-circuit emulator:

The RE32N in-circuit emulator can be used if a special-purpose PROM programming adapter (product name:

LC72P366 RE32N) is used. Use the PGOTP command as the write method.

• Special-purpose writing adapters

Since there are two special-purpose PROM programming adapters as mentioned above, the correct adapter must be

used.
