Descargar "Modify the CH341A EEPROM Programmer (Black Edition) for 5V 93XXX & 95XXX Automotive Use"

In this video I'll go over a combination of programmer software, EEPROM adapter, and programmer printed circuit board (PCB) modifications to allow +5V 93XXX (e.g., 93C66) and +5V 95XXX (e.g., 95040) SOIC8 / SO8 EEPROMs to also be supported by the ubiquitous CH341A USB MinProgrammer (Black Edition), in addition to its usual SO8 24XXX and 25XXX device support, but now in +5V as well (e.g., 24C08). With this support you can use this programmer to change VIN information in most Radio or Body Control Module (BCM) types sold in the USA from the 1990s and early to mid 2000s, as well as to perform odometer mileage correction manually in these same BCMs or an instrument cluster, for example. In order to reliably write some SO8 EEPROM devices encountered in automotive circuits a +5VDC supply and programming voltage, rather than the default +3.3VDC, is required. This particular inexpensive programmer can be easily modified for this automotive module voltage requirement and allow for doubling the number of supported devices in doing so as well (from 2 to 4 EEPROM families) as shown in this video. While not all SO8 EEPROM devices can be written, or even read, in-circuit of automotive module circuit designs many can, and for those that cannot this programmer can still provide a very inexpensive DIY solution for light duty repair projects off circuit as well. These inexpensive programmers lack the over current protection or pin protection of most general purpose programmers, which allows them to be used for in-circuit reading and writing as well as off circuit for many (though not all) automotive modules. *NOTE: In order to read 93Sxxx security devices you will have to explicitly connect pin 7 (PRE) to ground (pull low) rather than leave it floating like I showed for 93CXXX devices.* *CH341A USB to Serial Device Driver* Here is a link to the Microsoft Windows specific USB serial device driver from the actual manufacturer of the CH341A chip that forms the heart of this particular black edition EEPROM programmer: http://www.wch-ic.com/download/CH341SER_EXE.html *AsProgrammer EEPROM Application Software* The only reliable programmer software I have found to work with this Black Edition CH341A for 93XXX and 95XXX support, as well as retaining the 24XXX and 25XXX series, is a more recent private fork version of the open source AsProgrammer project (which is for Microsoft Windows). Here is a public link to version 2.1.0.13 (earlier 1.4.x and 2.0.x public versions do NOT work with 93XXX devices and the Black Edition) and so I can only recommend this closed source version 2.1.0.13 or higher (just the link.txt file has what you need): http://forum.easyelectronics.ru/viewtopic.php?f=17&t=10947&sid=b714c30e69c75dba387a09a25cb991ec&start=2376 Here's a translation of the Russian page to US English JUST FOR READING, the link.txt file for the download location usually will not work from within a Google translate page: https://translate.google.com/translate?hl=en&sl=ru&tl=en&u=http%3A%2F%2Fforum.easyelectronics.ru%2Fviewtopic.php%3Ff%3D17%26t%3D10947%26sid%3Db714c30e69c75dba387a09a25cb991ec%26start%3D2376 *NOTE:* the above link is within Google Translate (since it's on a Russian electronics site where this AsProgrammer project was discussed) so you won't be able to click the mega.nz download link.txt from that post directly.
