ATT1C05

The ATT1C05 is the second generation of SRAM-based field-programmable gate arrays from AT&T.The ATT1C and ATT2C FPGA series provide elecen CMOS FPGAs ranging in complexity from 3,500 to 26,000 gates in a variety of packages,speed grades and temperature ranges.This datasheet covers the first four members of the ORCA series:Att1C03,ATT1C05,ATT1C07 and ATT1C09.

Features of the ATT1C05 can be summarized as:(1)high density:to 11,400 usable gates;(2)high I/O:up to 256 usable I/O(for ATT1C09);(3)high-performance 0.6 um CMOS technology;(4)fast on-chip user SRAM:64 bits/PLC;(5)innovative programmable logic cell(PLC) architecture for hign density and routability;(6)four 16-bit look-up tables and four latches/flip-flops per PLC;(7)internal carry for fast arithmetic functions;(8)TTL or CMOS input thresholds programmable per pin;(9)individually programmable drive capability:12 mA sink/6 mA source or 6 mA sink/3 mA source;(10)nibble-oriented architecture for implementing 4-,8-,16-,32-bit bus interfaces;(11)built-in boundary scan(IEEE 1149.1);(12)100% factory tested;(13)low power consumption.

The ATT1C05 absolute maximum ratings can be summarized as:(1)the storage temperature:-65 to 150;(2)supply voltage with respect to ground:-0.5 to 7.0V;(3)input signal with respect to ground:-0.5 to Vdd+0.3 V;(4)signal applied to high impedance output:-0.5 to Vdd+0.3 V;(5)maximum soldering temperature: 260.
