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 This product is a PROM programming adapter for the 4513, 4514, 4518, 4519, 4583 and 4584 Groups of 4-bit MCUs. This product is used to write programs into the internal EPROM of MCU with commercially available PROM programmer. This manual mainly explains specifications of this product and how to operate it. Figures 2.1 to 2.3 show the external view of the products and their constituent parts. Figure 2.1 External view of the adapter and constituent parts (PCA7441) Figure 2.

When unpacking, check to see that it contains all of the components. Table 2.1 Package components Main unit PCA7441/PCA7442FPG02/PCA7442SP Interface unit PCA7414B Connector PCA7402D (28-pin) User's manual This manual * If any part is missing or there is any doubt about your product package, contact your local distributor.
Chapter 3. How to Write Programs 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 Procedures Follow the steps (1) to (6) to write the program. (1) Read the program into the PROM programmer. (2) Attach the adapter to the PROM programmer. (see 3.2). (3) Insert the MCU into the adapter. (see 3.
3.2 Attaching the Adapter to a PROM Programmer As shown in Figure 3.1, attach the No. 1 pin of the PCA7402D connector (standard-pitch 28-pin pinheader mounted) to the No. 1 pin of the IC socket of the PROM programmer. Be careful when attaching to the PROM programmer because an incorrect insertion can cause fatal damage to the MCU. Figure 3.1 Attaching the adapter to a PROM programmer 3.3 Inserting an MCU into the Adapter (1) For PCA7441 As shown in Figure 3.
(2) For PCA7442FPG02 As shown in Figure 3.3, insert the MCU into the IC socket with the No. 1 pin of the MCU matched to the No. 1 pin of the IC socket on the PCA7442FPG02. Be careful when attaching to the PROM programmer because an incorrect insertion can cause fatal damage to the MCU. Top view Figure 3.3 Inserting an MCU (PCA7442FPG02) (3) For PCA7442SP As shown in Figure 3.4, insert the MCU into the IC socket with the No. 1 pin of the MCU matched to the No. 1 pin of the IC socket on the PCA7442SP.
CAUTION Cuation for the Slide Bar of the PCA7441: • There is a slide bar in the center of the PCA7441. Set this slide bar to the shaded area (factory-setting). Otherwise the MCU may cause a break because of an electrical insulation failure. 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 Recommended PROM Programmers The PROM programmers listed in Table 3.1 are recommended for this product. 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 listed in Table 3.1 can not be supported. For how to operate the PROM programmer and the latest type of PROM programmers, contact the manufacturer to confirm whether it can be used for your product. Table 3.
Chapter 4. Specifications 4.1 Specifications Table 4.1 lists common specifications of the programming adapters, and Table 4.2 lists individual specifications of each programming adapter. Table 4.1 Common specifications of the PCA7441, PCA7442FPG02 and PCA7442SP Operating clock frequency Power supply Main unit Board configuration PCA7414B (Interface unit) PCA7402D (Connector) 1.
4.2 Memory Maps Figure 4.1 shows memory maps of the MCU and the PROM programmer. PROM programmer MCU 0000h 0000h *1 Programming area*3 (10 bits x ZZZZZ words) Lower 5 bits XXXXh XXXXh Unused area*4 *2 3FFFh 3FFFh 4000h *1 Upper 5 bits YYYYh *2 7FFFh *1: This area is fixed to "1" on the PROM programmer. *2: Set "FFh". *3: When writing, the lower 5 bits and the upper 5 bits are divided and then written into the MCU. *4: When reading, "1" is read out.
Chapter 5. Troubleshooting The table below summarizes errors to be checked carefully before you determine them to be a fault. 5.1 Errors That Occur When Writing to PROM (1) When Newly Purchased Remedy See page Is the adapter attached to the correct position of the PROM programmer? 9 Is the MCU attached to the correct position? 9 Is the correct device selected? 12 Cause Programming adapter PROM programmer Contact failure The IC socket of the PROM programmer may be stained.
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.
