AT40K20-2EQI

The AT40K20-2EQI is an SRAM-based Field Programmable Gate Array (FPGA) in a 240-pin BFQFP package designed for high-performance, reconfigurable logic. It provides 1,024 logic elements, approximately 8,192 bits of embedded RAM, and 193 I/O pins to support complex digital designs.

Built on the AT40K family architecture, the device targets applications that need fast on-chip memory access, multiple global clocks and in-system reconfigurability. Its combination of 10 ns distributed SRAM, global clock resources and industrial-grade operating range make it suitable for demanding embedded and DSP-oriented designs.

Key Features

• Logic Capacity — 1,024 logic elements (cells) and approximately 30,000 usable gates provide programmable logic resources for mid-range designs.
• Embedded Memory (FreeRAM) — Distributed 10 ns SRAM totaling 8,192 bits that can be implemented as single- or dual-port, synchronous or asynchronous RAM without consuming separate logic resources.
• I/O and Interface — 193 I/O pins with family-level PCI-compliant I/O architecture and 3V/5V capability; programmable output drive and fast, flexible array access for pin locking.
• Clocking — Up to 8 global clocks with low-skew distribution, programmable edge transitions, and distributed clock shutdown for power management.
• Reconfigurability — Cache Logic dynamic partial/full in-system reconfigurability with unlimited re-programmability via serial or parallel modes for adaptive designs and runtime updates.
• Performance — Family features include system speeds to 100 MHz, array multipliers >50 MHz, and 10 ns SRAM timing for high-throughput implementations.
• Package & Supply — 240-BFQFP (supplier package: 240-PQFP, 32×32) with a recommended supply range of 4.5 V to 5.5 V.
• Industrial Temperature Range — Rated for operation from –40°C to 85°C; RoHS compliant.

Typical Applications

• DSP Coprocessing — Implement FIR filters, FFTs, convolvers and other compute-intensive blocks that benefit from fast array multipliers and distributed RAM.
• Video and Multimedia — Use reconfigurable logic and on-chip memory for video compression/decompression, transforms and real-time data paths.
• PCI/High-speed I/O Systems — Leverage the PCI-compliant I/O architecture and programmable drive strengths for board-level interface logic and protocol glue.
• Adaptive In-System Logic — Employ Cache Logic partial/full reconfiguration to update algorithms or coefficients in-system without data loss.

Unique Advantages

• Distributed Fast SRAM — On-chip 10 ns FreeRAM enables low-latency data storage and scratchpad memory without consuming logic elements, simplifying FIFOs and buffers.
• Dynamic Reconfiguration — Cache Logic supports full or partial reconfiguration in-system, enabling field updates and adaptive algorithm changes.
• Robust Clocking — Eight global clocks with programmable transitions and low skew enable multi-clock domain designs and precise timing control.
• I/O Flexibility — High pin count (193) with 3V/5V capability and programmable output drive supports mixed-voltage board designs and a wide range of peripherals.
• Production-Ready Package — 240-pin BFQFP (240-PQFP footprint) provides an industry-standard surface-mount form factor for production deployment.
• Design Ecosystem Integration — Family-level support for industry-standard design flows and automatic component generators accelerates development and reuse of IP.
