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 Warning 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. • Use caution when handling this product. Be careful not to apply a mechanical shock such as falling.
2. Introduction This product is a flash memory programming adapter for Renesas 38000 Series of 8-bit microcomputers. The adapter is a tool that can be used to write programs into internal flash memory of microcomputers using a commercially available PROM programmer. This manual describes the specifications and the operation. Figure 2.1 shows the external view and constituent parts of the adapter. Figure 2.1 External view and constituent parts 2.
3. Specifications Table 3.1 lists specifications of the programming adapter. Table 3.1 Specifications of the programming adapter Applicable MCU M38B79FFFP (100-pin 0.65mm-pitch QFP) 1MHz (Supplied by the ceramic oscillator mounted on the adapter) Operating clock frequency Power supply Supplied from Vcc of the PROM programmer IC socket IC51-1004-814-6 (made by Yamaichi Electronics Co., Ltd.
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 (8) 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) Set the jumper switches (SW1, SW2 and SW3). (see section 4.4) (4) Insert the MCU into the adapter.
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 Programming Adapter As shown in Figure 4.2, insert the No. 1 pin of the MCU into the No. 1 pin of the IC socket on the main unit. Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU. Top view Figure 4.
4.4 Setting Jumper Switches (1) Jumper Switch SW1 Set the jumper switch SW1 according to the output format of the MCU ports P20 to P23. The examples of switch settings are shown in Table 4.1 and Figure 4.3. • When ports P20 to P23 are CMOS output ........................................................ SW1: CMOS • When ports P20 to P23 are Pch output .............................................................. SW1: Pch • When ports P20 to P23 are Nch output ................................................
4.5 Precautions When Opening and Closing IC Socket When opening and closing the IC socket, hold the adapter horizontally as shown in Figure 4.4. Otherwise the inside of the IC socket may become damaged and cause an electrical insulation failure. Side view Figure 4.4 Holding the adapter in a horizontal position 4.6 Precautions When Handling Adapter Do not directly touch the connector in the IC socket and the pins on the PROM programmer connector because dirt may cause an electrical insulation failure.
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.

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? 10 Is the area specification set correctly? 12 Is the correct device selected? 13 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.
