Sanyo LC6527F One-time programmable 4-bit single-chip microcontroller Datasheet

Ordering number : EN5894
CMOS IC
LC65P29
One-Time Programmable 4-Bit Single-Chip
Microcontroller
Overview
Package Dimensions
The LC65P29 is a one-time programmable (on-chip
PROM) version of Sanyo's LC6529N/F/L 4-bit single-chip
CMOS microcontroller. It provides identical functionality
to, and pin compatibility with, the mask ROM versions of
the LC6529N/F/L, and provides a 1-KB internal PROM.
The LC65P29 is provided in DIP24S and MFP30S plastic
packages and the program can be written by the customer,
thus makes this IC appropriate for the limited-run products
and the startup of initial production of new products.
Furthermore, it can provide reduced changeover periods
when end product specifications change.
Additionally, the LC65P29 can function as a one-time
programmable PROM version of the Sanyo LC6527N/F/L
and LC6528N/F/L by using the 29T27 adapter socket.

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.

Usage Procedures
• Option specification procedures
User options can be selected interactively by running the LC6529 option entry software (SU60K). This creates an
option file (file.opt).
Assembling the user program with the macro assembler (M60K) creates an object file. An evaluation file (file.eva) can
be created by linking the object file and the option file with the linker (L60K). Then, a HEX format object file, which
includes both the user program and the mask options, can be created by converting the evaluation file with the file
conversion software (E2H60K). This creates the option codes in the option specification area (locations 400 to 404H).
It is also possible to store data directly to the option specification area. Refer to the option code creation table on page 9
to do this.
Refer to the “LC65/66K Software Manual” for details.
• EPROM programming procedure
A general-purpose EPROM programmer can be used to write the created data to the LC65P29 by using a specialpurpose write conversion board (either the W65EP29D or the W65EP29M).
— The EPROM programmers listed below can be used.

— The “27512 (VPP: 12.5 V) Intel fast write” method must be used for writing. Specify locations 0 to 404 as the
address settings, and make sure that the DASEC jumper is in the off position.
• Using the data security function
The data security function is a function that prevents data written previously to the microcontroller EPROM from being
read out. Use the following procedure to apply the data security to the LC65P29.
1. Set the DASEC jumper on the write conversion board to the on position.
2. Write the data once again.
At this point, the EPROM writer will indicate an error since this function has operated, but actually, no error has
occurred in either the programmer or the IC.
Notes: • The data security function will not be applied if the data value FF is written to all address in step 2.
• The data security function will not be applied if the sequence BLANK → PROGRAM → VERIFY is performed
at step 2.
• Always return the jumper to the off position after performing this procedure.

Note: The reset period due to a CRES with a value of 0.68 µF will be 10 to 100 ms
when the power supply rise time is zero.
If the power supply rise time is relatively long, increase the value of CRES
so that the reset time is at least 10 ms, which is the oscillator stabilization
time.

Notes on One-Time Programmable Microcontroller Screening
Due to the structure of their circuits, it is not possible for Sanyo to fully test one-time programmable microcontroller
products before the PROM has been written. To increase the reliability after the PROM has been written, we strongly
recommend screening these products after writing according to the following flowchart.

Due to the structure of the one-time programmable microcontroller PROM circuit in the state before writing, it is not
possible to write test all the bits in the device. This means that it is impossible to guarantee a yield of 100%.
