Modification 2: Add a 1000uF 16V elco capacitor to the USB power line, positive side of capacitor goes to the plus pole, and negative side of capacitor goes to the minus pole of USB power line. #CH341 PROGRAMMER SOFTWARE 64 BIT#Now we have 5V power for our 95xxx eeproms.ģ. File name: ch341ser-infwin764bit.exe Version: 2.3.7 File size: 3.300 MB Upload source: other website Antivirus software passed: F-Secure Download Driver (click above to download).Ch341 64 Bit Drivers Are The Both the CH340 and CH341 can realize the function of USB to serial port, and their drivers are the same. Now solder a short piece of wire from 5V pin to pin number one on the socket. Modification 1: 95xxx eeproms are read/write by inserting them to the 25xxx labeled socket and thats where we need to cut the 3.3V trace on the backside on the PCB. Luckly on the programmer there is 5VDC pin which we will be use to get this power from.Ģ. But to write and read to automotive 95xxx series eeproms we need to supply 5VDC. For reading and writing to those eeproms, 3.3 V power is supplied from the programmer its self. This programmer supports two types of eeprom, 24xxx (I2C) and 25xxx(ISP) series, so on the ZIF socket there are labels which indicate where to insert which type of EEPROM.
