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. 1.
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 Cautions to Be Taken for 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. • Use caution when handling this product.
Chapter 2. Introduction The PCA7447FP is a PROM programming adapter for M38C89EFFP (8-bit MCU). The PCA7447FP is used to write programs into the internal EPROM of MCU with commercially available PROM programmer. This manual mainly explains specifications of PCA7447FP and how to operate it. Figure 2.1 shows the external view of the product and its constituent parts. Figure 2.1 External view of adapter and constituent parts (IC socket: QFP) 2.
Chapter 3. Specifications Table 3.1 lists specifications of the programming adapters. Table 3.
Chapter 4. How to Write the Program 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. 4.1 Programming Procedure Follow steps (1) to (7) below to write the program. (1) Read the program into the PROM programmer. (2) Attach the adapter to the IC socket of the PROM programmer. See "4.2 Attaching Adapter to PROM Programmer" (page 9). (3) Insert the MCU into the adapter. See "4.
4.2 Attaching Adapter to PROM Programmer As shown in Figure 4.1, attach the No. 1 pin of the PCA7402E connector (standard-pitch 32-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 incorrect insertion can cause fatal damage to the MCU. Figure 4.
4.3 Inserting MCU into Adapter As shown in Figure 4.2, 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 PCA7447FP. Be careful when attaching to the PROM programmer because incorrect insertion can cause fatal damage to the MCU. Top view Figure 4.
4.4 Precautions When Opening and Closing the IC Socket When opening and closing the IC socket, keep the IC socket side above and horizontal. Otherwise the inside of the IC socket may become damaged and cause an electrical insulation failure. Figure 4.3 shows the state of opening and closing the IC socket to insert the MCU. Side view Figure 4.3 Opening and closing the IC socket and inserting MCU 4.
Chapter 5. Recommended PROM Programmers The PROM programmers listed in Table 5.1 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 can not be supported. For the latest type of PROM programmers, contact the manufacturer to confirm whether it can be used for your product. Table 5.
Chapter 6. Memory Maps Figure 6.1 shows memory maps of the MCU and the PROM programmer. 000016 0000016 Unused area 100016 107F16 108016 Reserved ROM area Internal memory area (60K bytes) FFFD16 FFFE16 FFFF16 Reserved ROM area 0107F16 0108016 Programming area Unused area 0FFFD16 0FFFE16 0FFFF16 1000016 Unused area 1FFFF16 MCU PROM programmer (M5M27C101 mode) Figure 6.
Chapter 7. Troubleshooting The table below summarizes errors to be checked carefully before you determine them to be a fault. 7.1 Errors That Occur When Writing to PROM 7.1.
7.2 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.
