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. Figure 2.1 shows the external view of the PCA7400 and its constituent parts. Figure 2.1 External view of the adapter and its constituent parts 2.
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). (2) Attach the adapter to the IC socket of the PROM programmer (see section 3.2). (3) Set the programming area with the PROM programmer (see section 3.4).
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. Figure 3.
3.3 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). Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU. Top view No. 1 pin of socket No. 1 pin of MCU IC socket on the PCA7400 Figure 3.
3.4 Setting the Programming Areas When writing the program into the MCU, be sure to set the programming area. And also, specify its device of the PROM programmer. Table 3.1 Programming areas MCU type name PROM programmer Device Programming area ROM capacity Internal ROM (60K+20K bytes) M27281EKSP ROM area of MCU 0100016--0FFFF16 1B00016--1FFFF16 0100016--0FFFF16 1B00016--1FFFF16 1080016--157FF16 1800016--1ACFF16 1080016--157FF16 1800016--1ACFF16 M5M27C101 OSD display (20400+9672 bytes) 3.

4.2 Memory Maps Figure 4.1 shows memory maps of the MCU and the PROM programmer.
Chapter 5. Troubleshooting The table below summarizes errors to be checked carefully before you determine them to be a fault. 5.
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. Check your program again.
