DLP- DLP- 2232MSPF 2232MSPF LEAD FREE USB / MICROCONTROLLER MODULE The DLP-2232MSPF combines the same USB interface used in the DLP-2232H and the DLP-1232H modules with a Texas Instruments microcontroller with internal FRAM to form a rapid development tool. The MSP430FR5739 microcontroller is preprogrammed with basic functionality for accessing the port pins and can be reprogrammed with user firmware via a 12-pin header using the MSP-FET430UIF device programmer/debugger (purchased separately). FEATURES: The DLP-2232MSPF module utilizes a Texas Instruments 16-bit RISC architecture processor with 16K bytes FRAM, 1K bytes RAM and a multi-channel,10-bit A/D converter Up to 24MHz operation Ultra low power FRAM operates as unified memory and is configurable as code, data or storage memory FRAM write access and code execution at up to 24MHz 14 FRAM has virtually unlimited write endurance (10 cycles) FRAM is inherently secure and radiation resistant The DLP-2232MSPF has 26 digital I/O lines available for interfacing to user electronics via a compact, 40-pin DIP footprint module (12 can be configured as A/D inputs) Send/receive data over a high-speed USB 2.0 interface to a host computer at 1M baud (921600) Required 5V power supply can be taken directly from the USB port or supplied by user electronics Token I/O code is preprogrammed into the MSP430FR5739s FRAM memory for basic port pin input/output capability including access to the A/D converter The FRAM memory can be easily erased and reprogrammed utilizing a user-supplied compatible programmer or a user-supplied internal bootstrap loader through UART UCA0 No in-depth knowledge of USB is required as all USB protocols are handled automatically by the on-board FT2232H and its support circuitry Royalty-free device drivers eliminate the need for USB driver development in most cases USB bulk or isochronous data-transfer modes USB 1.1 and USB 2.0 compatible USB VID, PID, serial number and product-description strings are stored in on-board EEPROM memory Rev. 1.1 (November 2011) 1 DLP Design, Inc.

To send data from the peripheral to the host computer, the microcontroller simply writes data into the FT2232H on its RXD pin at 1M baud. Commands and data sent from the host are transferred serially on the TXD pin. By using FTDIs Virtual COM Port Drivers, the peripheral looks like a standard COM port to the application software. The latest versions of the drivers are available for download from DLP Designs website at www.dlpdesign.com. 2.0 DRIVER SOFTWARE FTDI s VCP (Virtual COM Port) driver-executable files are provided royalty free on the condition that they are used only with designs incorporating an FTDI device (i.e. the FT2232H on the DLP-2232MSPF). The latest version of the drivers can be downloaded from www.dlpdesign.com or www.ftdichip.com. The VCP driver download file is a combined set of drivers for Windows 7, Windows Vista and Windows 2000/XP. Unzip the file to a blank floppy disk or folder on your PC. (The drivers can coexist on the same floppy disk or folder since the INF files determine which set of drivers to load for each operating system version.) Once loaded, the VCP drivers allow the application software running on your host PC to communicate with the DLP-2232MSPF as though it were connected to a COM (RS-232) port. In addition to VCP drivers, FTDI s D2XX direct drivers offer an alternative solution to the VCP drivers that allow application software to interface with the DLP-2232MSPF using a DLL instead of a Virtual COM Port. The architecture of the D2XX drivers consists of a Windows WDM driver that communi- cates with the device via the Windows USB stack and a DLL that interfaces the application software (written in VC++, C++ Builder, Delphi, VB, etc.) to the WDM driver. The D2XX direct drivers add support for simultaneous access and control of multiple FT2232H devices. The extended open function (FT OpenEx) allows the device to be opened by either its product description or serial number, both of which can be programmed to be unique.
