Usage Notes
The LC66P5316 was created for program development, product evaluation, and prototype development for products
based on the LC6653XX Series microcontrollers. Keep the following points in mind when using this product.
1. After a reset
The RES pin must be held low for an additional 3 instruction cycles after the oscillator stabilization period has
elapsed. Also, the port output circuit types are set up during the 9 instruction cycles immediately after RES is set
high. Only then is the program counter set to 0 and program execution started from that location. (The port output
circuits all revert to the open-drain type during periods when RES is low.)

2. Notes on LC6653XX evaluation
The high end of the EPROM area (locations 3FF0H to 3FFFH) are the option specification area. Option specification
data must be programmed for and loaded into this area. The Sanyo specified cross assembler for this product is the
program LC66S.EXE. Also, insert JMP instructions so that user programs do not attempt to execute addresses that
exceed the capacity of the mask ROM, and write zeros (00H) to areas (other than 3FF0H to 3FFFH) that exceed the
actual capacity of the mask ROM.
3. Mounting notes
Due to structural considerations, Sanyo is unable to fully test one-time programmable products. Therefore, the user
must apply the screening procedure described on page 20 to these products.
4. Use the following procedure when ordering ROM through the Sanyo PROM writing service. (Note that this is a for-
fee service.)
If ordering one-time programmable and mask ROM versions at the same time:
The customer must provide the EPROM for the mask ROM version, the order forms for the mask ROM version,
and the order forms for the one-time programmable version.
If ordering only the one-time programmable version:
The customer must provide the EPROM and the order forms for the one-time programmable version. The last
section of the EPROM (locations 3FF0H to 3FFFH) is the option specification area, and the option specification
data must be written to this area. The Sanyo specified cross assembler for this product is the program LC66S.EXE.
Also, insert JMP instructions so that user programs do not attempt to execute addresses that exceed the capacity of
the mask ROM, and write zeros (00H) to areas (other than 3FF0H to 3FFFH) that exceed the actual capacity of the
mask ROM.
5. Differences between this product and the mask ROM version:
Carefully read the sections on the following pages that describe these differences.
