Four-Bit Single-Chip Microcontroller
with 16 KB of On-Chip EPROM
Preliminary
Overview
Package Dimensions
The LC66E2316 is an on-chip EPROM version of the
LC6623XX Series CMOS 4-bit single-chip micro-
controllers. The LC66E2316 provides the same functions
as the LC662316A, and is pin compatible with that
product. Since the LC66E2316 is provided in a window
package, it can be reprogrammed repeatedly and is thus
optimal for program development.

Usage Notes
The LC66E2316 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. Always apply an opaque seal to the window on the LC66E2316 package when actually using the device.

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 LC66E2316, 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 LC66E2316.
• The EPROM programmers listed below can be used.

• The “27512 (V 12.5 V) Intel high-speed write” technique must be used to write the EPROM. Set the address
PP
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 LC66E2316 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.

4. Erase procedure
Use a general-purpose EPROM eraser to erase data written to the EPROM.
