DLP-2232ML-G LOW-PROFILE USB MODULE * Lead Free * 1.0 Introduction The DLP-2232ML-G utilizes FTDI s third-generation USB UART/FIFO I.C., the FT2232D. This low-cost, RoHS compliant development tool features two Multi-Purpose UART/FIFO controllers that can be configured individually in several different modes. In addition to the UART interface, FIFO interface, and Bit-Bang IO modes of the second-generation FT232BM and FT245BM devices, the FT2232D offers a variety of additional modes of operation including a Multi-Protocol Synchronous Serial Engine interface designed specifically for synchronous serial protocols such as JTAG and SPI bus. The DLP-2232ML-G features a quality four-layer printed circuit board with a solid ground plane, an integral 93C56 EEPROM on board for easy OEM customization and a standard 40-pin, 0.6in wide footprint. Integral power control and on-board MOSFET power switch make the DLP-2232ML-G a perfect choice for USB bus-powered, high- power designs as well as self- and low-powered products. NOTE: With the exception of the mechanical connectors, mechanical dimensions and the host connection interface signals, the DLP-2232ML-G and DLP-2232M-G are the same product. The supporting electronics for the USB connector are already on the DLP- 2232ML-G board, just add a type B connector to your design and youre ready to go. For a complete list of features and specifications please refer to the datasheet for the DLP-2232M-G. Rev 2.1 (July 2008) 1 DLP-2232ML-G DLP Design, Inc. 2.0 Module Pin-Out 1 40 20 21 Figure 2. Pin-Out (40 Pin DIP Header ) 2.1 Pin Definitions Since the DLP-2232ML-G does not have a USB connector, the USBDM and USBDP signal lines are brought out on pins 23 and 22 as shown here. With the exception of the 2 USB communications lines (USBDP and USBDM) and pin 20, the pinout for the DLP-2232ML-G is the same as the DLP-2232M-G module. Please refer to the datasheet for the DLP-2232M-G for a complete description of the pinout. Rev 2.1 (July 2008) 2 DLP-2232ML-G DLP Design, Inc. FT2232C
