20p seat-809h

RT809H supports Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10. It does not require an external power supply, has low power consumption, and can be used as a VGA signal generator for easy maintenance. It has intelligent sensing function. Most chips support intelligent identification and random placement when reading and writing offline. Supports 24/25/93/95 series serial SPI Flash, EEPROM offline reading and writing. Supports 26/27/28/29/30/39/49/50 series NOR Flash/PROM reading and writing. Supports automatic identification and offline reading and writing of TSOP48 and BGA packaged NAND Flash parameters. Supports mainstream devices, including E/EPROM, MCU, EC, SPI NOR flash, parallel NOR flash, SPI NAND, parallel NAND, ONENAND, MCP, EMMC, EMCP, etc. NAND_AUTO can recognize most NAND and then perform read and write operations. EMMC_AUTO uses a BGA adapter to support EMMC offline high-speed reading and writing (8bit bus). EMMC_AUTO_4BIT uses a BGA adapter to support EMMC offline high-speed reading and writing (4bit bus). EMMC_AUTO_1BIT uses a BGA adapter to support EMMC offline high-speed reading and writing (1bit bus). EMMC_AUTO_ISP reads and writes EMMC (1bit bus) in flying line mode. Supports online and offline EMMC identification, BOOT/USER/RPOM/GPP area reading and writing.
This project converts the 20P socket for mobile phone repair into an 809H pin layout solution, increasing the socket's expanded use.
 
The manual VCCQ voltage jumper can also allow the software to automatically adjust the voltage, with an encryption chip soldering position. One encryption chip can be used for multiple A seat to reduce the cost of tool picking.
