Atmel introduced the commercially available FPGA configuration ICs to provide single-chip configuration storage for FPGAs with as many as 8 million gates.
The 32-Mbit AT17F32 and AT17F32A have four times the density of any commercially available competing device. The AT17F32 is said to be the only FPGA configuration device available in production quantities that can store all 29 Mbits of configuration data required for Virtex II XC2V6000, XC2V8000 and Virtex II Pro XC2VP50 and XC2VP70 FPGAs. The AT17F32A provides single-chip storage for APEX EP2A70, Stratix EP1S60 and EPS180 and Stratix II FPGAs.
AT17F32/A devices have a memory paging capability that also allows the single-chip storage of as many as four different FPGA bit streams, reducing chip count and board real-estate in multiple FPGA systems. This capability is particularly useful in high resolution video entertainment applications such as large plasma display panels and commercial display modules.
Plasma display panels can need as many as three different FPGA configurations to interface to multiple controllers. Historically, each configuration has required its own EEPROM. Using the paging capability in the AT17F32/A, all three configurations can be stored in a single IC, reducing board size, system complexity and system cost.
The AT17F32 and AT17F32A offer 33-Mbit/s data transfer rate, page select pin options for storing different versions of the FPGA bit stream, and a simple 2-wire protocol. The device operates at 3.3V and may be programmed in-system in just 20 seconds using industry standard programmers, including the company's ATDH2200E programming kit.
Atmel's 32-Mbit AT17F32 and AT17F32A FPGA configuration memories are available in a 44-lead PLCC package and are priced at US$24 in quantities of 100,000 units.
