(6 / 14) 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 2.1 things to check when unpacking the PCA7414 consists of following parts and boards. check to see that it contains all of the components shown below. contents ? PCA7414 (main unit) 1 PCA7414b (interface unit) 1 pca7402d (prom programmer connector) 1 PCA7414 instruction manual (this manual) 1 if any part is missing or there is any doubt about your product package, contact your nearest office of mitsubishi or its distributor.

(8 / 14) 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. device name of prom programmers: m5m27c256a (made by mitsubishi) programming voltage: vpp = 12.5v 4.2 programming procedure follow these procedures (1) through (6) to write the program into the mcu. (1) read the program. read the program into the prom programmer. (2) attach the adapter to the prom programmer. (see section 4.3) (3) insert the mcu into the programming adapter. (see section 4.4) (4) check to erase the programming area. * using the prom programmer's erase check function, check whether data can be written into the mcu's programming area. (5) write the program into the mcu. * write the program into the program area of the mcu using the prom programmer. (6) check to verify the programming area. * check to verify the programming area of the mcu using the prom programmer. check whether the program is written into the mcu correctly. note: * some prom programmers perform the procedures (4) through (6) written above automatically.
(9 / 14) 4.3 attaching adapter to prom programmer attach the pin no. 1 of the pca7402d prom programmer connector (standard pitch 28-pin pin- header 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. figure 4.1 attaching adapter to prom programmer a a a a a aa aa aa aa aa aa aa aa these 4 pins are nc (non-connection).
(10 / 14) 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. otherwise the inside of the ic socket may become damaged and cause an electrical insulation failure. figure 4.3 shows in diagrammatic form the opening and closing of the ic socket. side view figure 4.3 opening and closing the ic socket 4.6 precautions when handling adapter don't touch the connector in the ic socket and the pins on the prom programmer connector lest it cause an electrical insulation failure because of dirt.
(11 / 14) 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 5.1 recommended prom programmers type name tr4943 r4944a r4945 r4945a manufacturer advantest programming voltage (vpp) 12.5 v device name m5l27256 mode m5m27c256 mode m5m27c256a mode
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.) ? detailed symptoms ? how often does the problem occur? (2 out of 10 etc.) ? when did the problem start to occur? (since purchase/used to work correctly) ? type name of the prom programmer (advantest r4945a etc.) ? specified device when writing to prom (m27c101 etc.) ? specified programming area when writing to prom ? switch settings of the adapter when writing to prom (12 /14)
