Budget board for FPGA development
A new 400k gate Spartan-3 FPGA development board provides a low-cost solution for design engineers looking to pursue a variety of embedded FPGA applications.
Platforms speed FPGA development
Nu Horizons Electronics Corp has two new development platforms based on the Spartan-3 family of low cost FPGAs from Xilinx.
The LF3312 is the most flexible memory device for buffering multiple video formats.
It uses both sequential and random access addressing and integrates both high-density 12Mbit memory and advanced addressing control logic.
The device features up to four data ports.
Flexible addressing allows it to perform first-in first-out (FIFO), shift register, synchronisation, and mixed sequential/random access functions.
With just over 12.4Mbit of memory and a maximum datarate of 74MHz, the LF3312 can buffer multiple video formats, including HDTV.
Devices can be cascaded to enable larger word-widths or FIFO depths.
A seamless address space is maintained in the random access mode, even when cascading multiple devices for high-resolution images.
Memory can be allocated as a single 12.4Mbit FIFO memory, or as two independently controlled 6Mbit FIFO memories.
Two independent memories enable multi-channel applications, such as buffering luma and chroma video components or multichannel synchronisation.
The input/output word widths are configurable to 8, 10, 12, 16, 20 or 24bit without wasting memory.
The LF3312 is aimed at broadcast video equipment, medical imaging, video editing systems, security surveillance systems, and machine vision.
The LF3312 is packaged in a 15 x 15mm small form factor 172-pin low profile ball grid array (LBGA) package.
The packages are available in RoHS compliant green (Pb-free and beyond) packaging.
