DLP-2232ML LOW-PROFILE USB MODULE
1.0 Introduction
The DLP-2232ML utilizes FTDI's third-generation USB UART/FIFO I.C., the FT2232C.
This low-cost 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 FT2232C 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-2232M 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-2232M 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 and DLP-2232M are the same
product. The supporting electronics for the USB connector are already on the DLP-
2232ML board, just add a type B connector to your design and you’re ready to go.
For a complete list of features and specifications please refer to the datasheet for the
DLP-2232M.

2.1 Pin Definitions
Since the DLP-2232ML 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) the
pinout for the DLP-2232ML is the same as the DLP-2232M module. Please refer to the
datasheet for the DLP-2232M for a complete description of the pinout.
