Usage Notes

The LC65P29 is designed for program development and evaluation for systems that use the LC6529N/F/L. The following

points require attention when using this product.

• Mounting notes

Due to the nature of the device, one-time programmable microcontrollers cannot be fully tested prior to shipment. This

means that users must perform the screening process described on page 14.

• ROM ordering procedure when using the Sanyo for-fee ROM writing service

The customer must abide by the following when using the Sanyo for-fee ROM writing service:

— When ordering both one-time programmable and mask versions at the same time

The customer must provide an EPROM for the mask version, the mask version order forms, and the one-time

programmable version order forms.

— When order only the one-time programmable version

The customer must provide an EPROM for the one-time programmable version and the one-time programmable

version order forms. The end area in the EPROM (locations 400 to 404H) is the option specification area and the

customer must program the option specification data in that area. The customer must use the cross assembler

specified by Sanyo.
