Chapter 1. Precautions for Safety In both the user's manual and on the product itself, several icons are used to insure proper handling of this product and also to prevent injuries to you or other persons, or damage to your properties. This chapter describes the precautions which should be taken in order to use this product safely and properly. Be sure to read this chapter before using this product.
WARNING Warnings for Use Environment: • This equipment is to be used in an environment with a maximum ambient temperature of 35˚C. Care should be taken that this temperature is not exceeded. • Select the proper programming mode of the PROM programmer. CAUTION Caution to Be Taken for Modifying This Product: • Do not disassemble or modify this product. Disassembling or modifying this product can cause damage. Disassembling and modifying the product will void your warranty.
Chapter 2. Introduction The PCA7401 is a PROM programming adapter for Renesas 8-bit 7200 Series MCUs. The 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 PCA7401. Figure 2.1 shows the external view of the PCA7401 and its constituent parts. Figure 2.1 External view of the adapter and its constituent parts 2.
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 (7) to write the program into the MCU. (1) Read the program into the PROM programmer. (2) Attach the adapter to the IC socket of the PROM programmer (see section 3.2). (3) Mount the MCU into the adapter (see section 3.3).
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. Figure 3.
3.3 Mounting an MCU into the Adapter As shown in Figure 3.2, insert the No. 1 pin of an MCU into the No. 1 pin of the IC socket. Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU. Top view Figure 3.2 Mounting an MCU CAUTION Caution to Be Taken for Handling an 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.
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. Table 3.

Chapter 5. Troubleshooting The table below summarizes errors to be checked carefully before you determine them to be a fault. 5.
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.
