This mini USB CH341A 24 25 Series EEPROM Flash BIOS USB Programmer is designed to support 24 EEPROM and 25 SPI flash 8pin/16 pin chips. This low-cost device equipped with a CH341A chip automatically recognizes 24 EEPROM and 25 SPI flash 8pin or 16pin. With 24/25 status indicator lamp enables the user to easily recognize the module’s working status. This module supports USB to TTL conversion and the SOP8 SOP16 to DIP8 converter board. This makes the connection with different chips easily and functions as a user-friendly awesome programmer.
CH341 is based on a USB bus convert chip, capable of supporting various modes such as UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through the USB bus. In UART mode, CH341 provides a different control signal such as serial transfer enable, serial receive in ready, etc. It also supplies a common MODEM communication signal to expand UART for a computer or upgrade a common synchronous interface device to a USB bus directly.
Whereas in the printer port mode, the standard USB printer port in CH341 EEPROM programmer compounds USB relevant protocol. Windows operating system is used to upgrade the ordinary parallel printer to a USB bus directly. In parallel mode, CH341 supports an 8-bit parallel in EPP or MEM mode. Thus it is used to input/output data directly without MCU/DSP. Besides, CH341A also supports some common synchronous serial such as 2-wire (SCL, SDA). And also 4-wire (CS, SCK/CLK, MISO/SDI/DIN, and MOSI/SDO/DOUT) interface. Moreover, this mini USB Programmer is compatible with Windows XP, Vista, Win7, and Win8 (32/64bit) operating systems.
