2. INTRODUCTION The PCA7414 is a programming adapter for 4-bit microcomputers of 4500 Series. The adapter is a tool that can be used to write a program into internal PROM of microcomputers using a commercially available PROM programmer. This manual describes the specifications and the operation of the PCA7414. Figure 2.1 shows the external view and constituent parts of the PCA7414. Figure 2.1 External view of PCA7414 and its parts 2.
3. SPECIFICATIONS Table 3.1 lists specifications of the PCA7414. Table 3.1 Specifications of PCA7414 Item Description MCU type M34551E8FP 1 MHz (Supplied by the ceramic oscillator mounted on the PCA7414) Supplied from Vcc of the PROM programmer IC51-0484-652 (Made by Yamaichi Electronics Co., Ltd.) Board to insert the programmable MCU (IC socket for 48-pin QFP is mounted.
4. HOW TO WRITE THE PROGRAM This chapter describes programming conditions and the programming procedure with a PROM programmer. For the operation of the PROM programmer, refer to the instructions of the PROM programmer. 4.1 PROGRAMMING CONDITIONS Programming conditions are shown here below. 4.2 Device name of PROM programmers: M5M27C256A (Made by Mitsubishi) Programming voltage: Vpp = 12.5V PROGRAMMING PROCEDURE Follow these procedures (1) through (6) to write the program into the MCU.
4.3 ATTACHING ADAPTER TO PROM PROGRAMMER Attach the pin No. 1 of the PCA7402D PROM programmer connector (Standard pitch 28-pin pinheader mounted) to the specified pin of the IC socket of the PROM programmer. Be careful when attaching the adapter because incorrect insertion can cause fatal damage to the MCU. AA A AA A AA A AA AA AA These 4 pins are NC (Non-connection). Figure 4.
4.4 INSERTING MCU INTO PROGRAMMING ADAPTER As shown in Figure 4.2, insert the MCU into the IC socket, with the pin No.1 of the MCU matched to the pin No.1 of the IC socket on the PCA7414. Be careful when inserting the MCU because incorrect insertion can cause fatal damage to the MCU. Top view Pin No.1 of MCU Figure 4.2 Inserting the MCU 4.5 PRECAUTIONS WHEN OPENING AND CLOSING IC SOCKET When opening and closing the IC socket to insert the MCU, hold the adapter horizontally.
5. RECOMMENDED PROM PROGRAMMER The PROM programmers listed in Table 5.1 are recommended for the adapter. 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.
6. How to Request for Support After checking this manual, fill in the following information and email to your local distributor. For prompt response, please specify the following information: (1)Contact address •Company name •Department •Responsible person •Phone number •Fax number • E-mail address (2)Product information •Name of the programming adapter •Serial number •Date of purchase •Target MCU •Symptoms (Fails blank check/Cannot write a program/Fails verification etc.
