LC72E32

Usage Techniques

1. Writing the on-chip EPROM

There are two techniques that can be used to write to the LC72E32’s on-chip EPROM.

• Use of a general-purpose EPROM programmer

The LC72E32’s EPROM can be written using a general-purpose EPROM programmer. This requires the use of a

special-purpose adapter, the LC72E32 Adapter for EPROM Programmer. Use the Intel 27512 (Vpp = 12.5 V)

high-speed writing technique, and specify the address settings as locations 0 to 2033H.

• Use of the RE32 in-circuit emulator

The LC72E32’s EPROM can be written using the RE32 in-circuit emulator. This requires the use of a special-

purpose adapter, the LC72E32 Adapter for RE32. Use the PGOTP command as the writing technique.

2. Special-purpose EPROM writing adapters

As mentioned above, there are two EPROM writing techniques, each of which requires the use of the appropriate

adapter.

Note: The external dimensions of these two adapters are essentially identical.

General-purpose EPROM programmer adapter:

Product name: LC72E32 Adapter for EPROM Programmer

Product code: NDK-DC-001-A

RE32 in-circuit emulator adapter:

Product name: LC72E32 Adapter for RE32

Product code: NDK-DC-003-A

• Erasure

Use a general-purpose EPROM eraser to erase written data.

• Light Seal

The LC72E32 includes UVEPROM, i.e., ultraviolet erasable EPROM. When actually using an LC72E32, its

window should be covered with UV-opaque tape.
