  • Page 8: Chapter 2. Introduction

    Chapter 2. Introduction The PCA7400 is a PROM programming adapter for the M37281EKSP (16-bit MCU). This adapter is a tool that can be used to write programs into an internal PROM of MCUs using a commercially available PROM programmer. This manual describes the specifications and the operation of the PCA7400.

  • Page 9: Chapter 3. Usage

    Chapter 3. Usage 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 Procedure Follow these procedures (1) through (6) to write the program into the MCU. (1) Mount the MCU into the adapter (see section 3.3).

  • Page 10: Attaching The Adapter To A Prom Programmer

    3.2 Attaching the Adapter to a PROM Programmer As shown in Figure 3.1, attach the pin No. 1 of the 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.

  • Page 11: Mounting An Mcu Into The Adapter

    As this product uses an IC socket for 54-pin shrink DIP, mount the MCU into the IC socket with the No. 1 pin of the MCU matched to the No. 2 pin of the IC socket on the PCA7400 (SET BOTTOM).

  • Page 12: Setting The Programming Areas

    M27281EKSP 3.5 Recommended PROM Programmers The PROM programmers listed in Table 3.2 are recommended for the adapter PCA7400. 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.

  • Page 16: Mcus Do Not Function Normally

    5.2 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.
