Chapter 2. Introduction

The PCA7400 is a PROM programming adapter for the M37281EKSP (16-bit MCU). This adapter is a tool that can be used to write programs into an internal PROM of MCUs using a commercially available PROM programmer.

This manual describes the specifications and the operation of the PCA7400.

Figure 2.1 shows the external view of the PCA7400 and its constituent parts.

2.1 Things to Check When Unpacking

This product consists of the following parts listed in Table 2.1. When unpacking, check to see that it contains all of the components shown in Table 2.1 below.

Chapter 3. Usage

This chapter describes procedures you need to follow when writing the program.

For details on how to operate the PROM programmer, refer to the user's manual of the PROM programmer.

3.1 Programming Procedure

Follow these procedures (1) through (6) to write the program into the MCU.

(1) Mount the MCU into the adapter (see section 3.3).

(2) Attach the adapter to the IC socket of the PROM programmer (see section 3.2).

(3) Set the programming area with the PROM programmer (see section 3.4).

(4) 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 programming area of the MCU using the PROM programmer.*

(6) Verify the programming area of the MCU using the PROM programmer to check whether the program has been written into the MCU correctly.*

Notes

* Be sure to set the programming area. Otherwise the mode's shift to the programming mode may not be performed successfully. The erase check function and others may not also be performed completely.

* Some PROM programmers perform the steps (4) to (6) automatically.

3.2 Attaching the Adapter to a PROM Programmer

As shown in Figure 3.1, attach the pin No. 1 of the connector (standard-pitch 32-pin pin-header mounted) to the pin No. 1 of the IC socket of the PROM programmer.

Be careful when attaching the adapter because incorrect insertion can cause fatal damage to the MCU.

( 8 / 16 )

3.3 Mounting an MCU into the Adapter

As this product uses an IC socket for 54-pin shrink DIP, mount the MCU into the IC socket with the

No. 1 pin of the MCU matched to the No. 2 pin of the IC socket on the PCA7400 (SET BOTTOM).

Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU.

CAUTION

Caution to Be Taken for Handling MCU:

• Do not touch the connector in the IC socket and the pins on the PROM programmer connector. Otherwise it can cause an electrical insulation failure because of dirt.

When not using, attach the connector pins of this product to the conductive sponge as it was shipped from the factory.

3.4 Setting the Programming Areas

When writing the program into the MCU, be sure to set the programming area. And also, specify its device of the PROM programmer.

3.5 Recommended PROM Programmers

The PROM programmers listed in Table 3.2 are recommended for the adapter PCA7400. 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.

5.1 Errors That Occur When Writing to PROM

(1) When Newly Purchased

( 13 / 16 )

5.2 MCUs Do Not Function Normally

The program operates normally on the emulator, but when the MCU that has normally been written is attached the same program does not function normally.

(1) Is the offset address specified correctly when copying data into the PROM programmer?

(2) In the emulator, NOPs are often inserted in the area where the program has not been read, therefore the program happens to appear functioning normally even though it may have gone wild. Check your program again.

(3) The emulator and the actual MCU may differ in characteristics. Consult the user's manual of the emulation pod to check for differences in characteristics again.

5.3 Other Precautions

(1) About the Recommended PROM Programmers

Not all PROM programmers available on the market can be checked to see if they function properly.

There are several PROM programmers that we have verified to function properly. These products are listed as recommended PROM programmers in this user's manual. Other PROM programmers may also be used providing that you verified them to function properly.

Note: No matter which type of PROM programmer you use, it is necessary to verify completion of programming by executing screening, etc. that are stipulated for each MCU used.

(1) About Reading Out of Device Identification Code *

1

Please do not use the PROM programmer's device identification code readout function.

Using this function may break down the MCU. The device identification code is included in EPROM to indicate the manufacturer code and device code; it is not included in the MCU.

*1 Depending on PROM programmer manufacturers, this may be referred to by another name (e.g.

ID code).
