DDLLPP--FFRR225566 LEAD FREE FERROELECTRIC MEMORY-BASED MICROCONTROLLER MODULE The DLP-FR256 combines the same USB interface used in the DLP-USB245R module (FTDI FT245R FIFO) with a Texas Instruments microcontroller with 256K of FRAM to form a rapid development tool. The MSP430FR5994 microcontroller is preprogrammed with simple firmware that demonstrates the on-board white noise generator and analog interface, and the DLP-FR256 can be reprogrammed with user firmware via four pins using an MSP-EXP430FR5994 Launchpad (purchased separately). FEATURES: The DLP-FR256 module utilizes a Texas Instruments 16-bit RISC architecture microcontroller with 256K bytes of FRAM, 8K bytes of SRAM and a multi-channel,12-bit A/D converter: Up to 16MHz operation Ultra-low power FRAM operates as unified memory and is configurable as code, data or storage memory. FRAM fast writes at 125nS per word (64KB in 4mS). 15 FRAM has virtually unlimited write endurance (10 cycles). FRAM is radiation resistant and nonmagnetic. The DLP-FR256 has 27 I/O lines available for interfacing to user electronics via a compact, 40-pin standard DIP footprint (two are configured with an onboard analog input interface for measuring voltage up to 20V). Send/receive data over a full-speed USB 1.1 interface to a host computer at up to 1MByte per second. Required 5V power supply can be taken directly from the USB port or supplied by user electronics. The FRAM memory can be easily erased and reprogrammed utilizing a user-supplied compatible programmer. No in-depth knowledge of USB is required as all USB protocols are handled automatically by the on-board FT245R and its support circuitry: Royalty-free device drivers eliminate the need for USB driver development in most cases.

To send data from the peripheral to the host computer, the microcontroller simply writes data into the FT245R on its 8-bit data bus. Commands and data sent from the host are transferred on the same shared bus. By using FTDIs Virtual COM Port Drivers, the peripheral looks like a standard COM port to the application software. The USB drivers are available for download from DLP Designs website at www.dlpdesign.com or from FTDI s website at www.ftdichip.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 FT245R on the DLP-FR256). The latest versions 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 all current versions of Windows. Unzip the file to a folder on your PC. (The drivers can coexist in the same 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-FR256 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 allow application software to interface with the DLP-FR256 using a DLL instead of a Virtual COM Port. The architecture of the D2XX drivers consists of a Windows WDM driver that communicates 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.
