On April 1 , 2010, NEC Electronics Corporation merged with Renesas Technology Corporation, and Renesas Electronics Corporation took over all the business of both companies. Therefore, although the old company name remains in this document, it is a valid Renesas Electronics document. We appreciate your understanding.

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.
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. Cautions in 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.
3. Specifications Tables 3.1 and 3.2 list the specifications of the PROM programming adapters. Table 3.1 Common specifications of the PROM programming adapters Operating clock frequency Power supply Board configuration Table 3.2 Each specification PCA7438F-64A PCA7438H-64A 1 MHz (Supplied by the ceramic oscillator mounted on the main unit) Supplied from the Vcc of the PROM programmer A programmable MCU mounted Main unit...
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.
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.
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.
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 Programming adapter PROM programmer Contact failure 7.1.2 Previously Written Normally Cause Programming adapter PROM programmer...
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.
