DLP2232PB开发板

• Send/receive data over USB to a host computer at up to 2 megabits per second 

• Standard .9 inch wide DIP footprint, 4 layer pcb with internal ground plane 

• 16 digital I/O lines (5 can be configured as A/D inputs) plus the 8-bit data bus available for interfacing to user electronics 

• Microchip 16F877A processor with 8K FLASH ROM, 368 bytes RAM, and a multi-channel, 10-bit A/D converter V1.7 Page 2 of 15 May 2010 

• “Token I/O” code preprogrammed into the 16F877A’s ROM for basic port pin input/output capability including access to the A/D, EEPROM, and external digital temperature sensors. ROM can be easily erased and reprogrammed with built-in Flash programmer or a usersupplied compatible programmer 

• On-board Flash programmer takes advantage of ‘A’ version Microchip microcontroller in that the entire 8K ROM can be programmed typically in under 4 seconds and read in under 1 second 

• No in-depth knowledge of USB is required as all USB protocol is handled automatically by the on-board FT2232D and its support circuitry • Royalty-free device drivers eliminate the need for USB driver development in most cases • USB bulk or isocronous data-transfer modes 

• Required 5V supply can be taken directly from the USB port or supplied by user electronics 

• USB 1.1 and USB 2.0 compatible • USB VID, PID, serial number, and product description strings stored in on-board EEPROM 

• Virtual com port (VCP) drivers for: - Windows 98 and Windows 98 SE - Windows 2000/ME/XP - Windows CE** - MAC OS-8 and OS-9 - MAC OS-X** - Linux 2.40 and greater 

• D2XX (USB direct drivers + DLL S/W interface) - Windows 98 and Windows 98 SE - Windows 2000/ME/XP ** In planning or under development.
