Overview
Package Dimensions
The LC66P2316 is an on-chip OTP PROM version of the
LC6623XX Series CMOS 4-bit single-chip microcontrollers. The LC66P2316 is appropriate for program
development and product evaluation since it provides
identical functionality and pin compatibility with the
LC662316A.

Please consult with your Sanyo representative for details on process conditions if the package itself is to be directly
immersed in a dip-soldering bath (dip-soldering techniques).

Usage Notes
The LC66P2316 was created for program development, product evaluation, and prototype development for products
based on the LC6623XX 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 LC6623XX 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 forfee 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.

Note: * Although the microcontroller will remain in hold mode if the RES pin is set low while it is in hold mode, always use the reset start sequence (after
switching HOLD from low to high, switch RES from low to high) when clearing hold mode. Also not that a current of about 100 µA flows from the
RES pin when it is low. This increases the hold mode current drain by about 100 µA.
See the data sheets for the individual products for details on other differences.

Usage Notes
1. Option specification
When using a Sanyo cross assembler with the LC66P2316, use the version called “LC66S.EXE” and specify the
actual microcontroller to be evaluated with the CPU pseudo instruction in the source file. The port options must be
specified in the source file. The cross assembler will create an option code list in the option specification area
(locations 3FF0H to 3FFFH). It is also possible to directly set up data in the option specification area. If this is done,
the options must be specified according to the option code creation table shown on the following page.
2. Writing the EPROM
Use a special-purpose writing conversion board (the W66EP5316D for the DIP package, and the W66EP2316Q for
the QFP package) to allow the EPROM programmers listed below to be used when writing the data created by the
cross assembler to the LC66P2316.
• The EPROM programmers listed below can be used.

MODEL1890A
• The “27512 (VPP 12.5 V) Intel high-speed write” technique must be used to write the EPROM. Set the address
range to location 0 to 3FFFH. The DASEC jumper must be off.
3. Using the data security function
The data security function sets up the microcontroller in advance so that data that was written to the microcontroller
EPROM cannot be read out.
Use the following procedure to enable the LC66P2316 data security function.
• Set the write conversion board DASEC jumper to the on position.
• Write the data to the EPROM once again.
At this time, since this function will operate, the EPROM programmer will issue an error. However, this error does
not indicate that there was a problem in either the programmer or the LSI.
Notes: 1. If the data at all addresses was “FF” at step 2, the data security function will not be activated.
Notes: 2. The data security function will not be activated at step 2 if the “blank → program → verify” operation
sequence is used.
Notes: 3. Always return the jumper to the off position after the data security function has been activated.

Preconditions for mounting one-time programmable microprocessors
Usage Notes
Due to inherent structural considerations, it is impossible to fully test one-time programmable microprocessors before
the PROM has been programmed, i.e. before shipment from the factory. We recommend that users screen products
whose PROM has been written according to the following procedure to improve the reliability of these products.
• Due to the nature of the product, it is not possible to test write operations to all bits in one-time programmable
microprocessors whose PROM has not been written. Therefore it may be impossible to guarantee a 100% yield on
writing to these products. Please understand that no such guarantee may be made.
• Storage of products in the moisture-proof packed (unopened) state
• Store products in moisture-proof packages in an environment in which the temperature is no higher than 30°C and
the relative humidity is no higher than 70%.
• Storage of products after opening the moisture-proof packaging
• After opening products that were packed in moisture-proof packaging, mount (solder) those products as soon as
possible. Store products for no more than 96 hours after opening the moisture-proof packaging in an environment
in which the temperature is no higher than 30°C and the relative humidity is no higher than 70%.
