2. INTRODUCTION
The PCA7414 is a programming adapter for 4-bit microcomputers of 4500 Series. The adapter is a tool
that can be used to write a program into internal PROM of microcomputers using a commercially available
PROM programmer.
This manual describes the specifications and the operation of the PCA7414.
Figure 2.1 shows the external view and constituent parts of the PCA7414.

4. HOW TO WRITE THE PROGRAM
This chapter describes programming conditions and the programming procedure with a PROM programmer.
For the operation of the PROM programmer, refer to the instructions of the PROM programmer.
4.1 PROGRAMMING CONDITIONS
Programming conditions are shown here below.
Device name of PROM programmers:
Programming voltage:
M5M27C256A (Made by Mitsubishi)
Vpp = 12.5V
4.2 PROGRAMMING PROCEDURE
Follow these procedures (1) through (6) to write the program into the MCU.
(1) Read the program.
Read the program into the PROM programmer.
(2) Attach the adapter to the PROM programmer. (See Section 4.3)
(3) Insert the MCU into the programming adapter. (See Section 4.4)
(4) Check to erase the programming area. *
Using the PROM programmer's erase check function, check whether
data can be written into the MCU's programming area.
(5) Write the program into the MCU. *
Write the program into the program area of the MCU using the PROM
programmer.
(6) Check to verify the programming area. *
Check to verify the programming area of the MCU using the PROM
programmer. Check whether the program is written into the MCU
correctly.
Note:
* Some PROM programmers perform the procedures (4) through (6) written above automatically.

4.3 ATTACHING ADAPTER TO PROM PROGRAMMER
Attach the pin No. 1 of the PCA7402D PROM programmer connector (Standard pitch 28-pin pin-
header mounted) to the specified pin of the IC socket of the PROM programmer.
Be careful when attaching the adapter because incorrect insertion can
cause fatal damage to the MCU.
These 4 pins are
NC (Non-connection).

4.4 INSERTING MCU INTO PROGRAMMING ADAPTER
As shown in Figure 4.2, insert the MCU into the IC socket, with the pin No.1 of the MCU matched
to the pin No.1 of the IC socket on the PCA7414.
Be careful when inserting the MCU because incorrect insertion can cause
fatal damage to the MCU.

4.5 PRECAUTIONS WHEN OPENING AND CLOSING IC SOCKET
When opening and closing the IC socket to insert the MCU, hold the adapter horizontally. Otherwise
the inside of the IC socket may become damaged and cause an electrical insulation failure. Figure
4.3 shows in diagrammatic form the opening and closing of the IC socket.

4.6 PRECAUTIONS WHEN HANDLING ADAPTER
Don't touch the connector in the IC socket and the pins on the PROM programmer connector lest
it cause an electrical insulation failure because of dirt.

5. RECOMMENDED PROM PROGRAMMER
The PROM programmers listed in Table 5.1 are recommended for the adapter. Using the actual products,
we have verified that these PROM programmers can be used to write programs without problem. Nonconformity
occurring by using any other PROM programmers can not be supported. For the latest type of PROM
programmers, contact the manufacturer to confirm whether it can be used for your product.
