1. Precautions for Safety In this User's Manual, 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 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 in Handling This Product: • Do not disassemble or modify this product. Personal injury due to electric shock may occur if this product is disassembled or modified. • Use caution when handling this product.
2. Introduction The PCA7438F-64A and PCA7438H-64A are PROM programming adapters for 8-bit 38000 Series 38C1 Group MCUs. These adapters are tools that can be used to write a program into internal PROM of MCUs using a commercially available PROM programmer. This manual describes the specifications and the operation of PCA7438F-64A/PCA7438H-64A. Figure 2.1 shows the external view and the constituent parts of them. Figure 2.1 External view of PCA7438F-64A/PCA7438H-64A and their constituent parts 2.
3. Specifications Tables 3.1 and 3.2 list the specifications of the PROM programming adapters. Table 3.
4. How to Write the Program This chapter describes how to write programs using a PROM programmer. For details on how to operate the PROM programmer, refer to the user's manual of the PROM programmer. 4.1 Programming Procedures Follow procedures (1) to (7) to write programs into the MCU. (1) Read the program into the PROM programmer. (2) Attach the adapter to the PROM programmer. (See Section 4.2) (3) Insert the MCU into the adapter. (See Section 4.
4.2 Attaching the Adapter to a PROM Programmer As shown in Figure 4.1, attach the pin No. 1 of the PCA7402E PROM programmer 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 4.1 Attaching the adapter to the PROM programmer 4.3 Inserting an MCU into the Programming Adapter As shown in Figure 4.
4.4 Precautions When Handling the Adapter Do not touch the connector in the IC socket and the pins on the PROM programmer connector, otherwise it 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. 4.5 Setting a Programming Area When writing the program into the MCU, be sure to set the programming area. And also, specify its device of the PROM programmer. Table 4.
6. Memory Maps Figure 6.1 shows memory maps of the MCU and the PROM programmer. 0000016 0000016 0A07F16 0A08016 0A07F16 0A08016 Internal ROM area (24K bytes) Programming area 0FFFD16 0FFFE16 0FFFD16 0FFFE16 1FFFF16 1FFFF16 MCU M38C13E6FP M38C13E6HP Figure 6.
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 ROM 7.1.1 When Newly Purchased Cause Remedy See page 9 Programming adapter Is the adapter attached to the correct position of the PROM programmer? Is the MCU attached to the correct position? 9 Is the area specification set correctly? 10 Is the correct device selected? 10 PROM programmer The IC socket of the PROM programmer may be stained.
7.2 MCU Does 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.
