AT40K40-2EQC

The AT40K40-2EQC is an SRAM-based FPGA from Microchip Technology’s AT40K family engineered for high-performance, reconfigurable logic applications. It delivers 2,304 logic elements, approximately 18,432 bits of distributed on-chip RAM, and 193 I/O pins in a 240-pin BFQFP package for designs that require dense logic, embedded memory, and flexible I/O.

Built with features from the AT40K series—including fast 10 ns SRAM, multi-clock support and Cache Logic dynamic reconfigurability—this device is well suited to system acceleration, DSP functions, and PCI-capable platform integration where reprogrammability and on-chip resources improve performance and design flexibility.

Key Features

• Core and Logic  2,304 logic elements (cells) enabling complex combinational and sequential logic implementations.
• Embedded Memory (FreeRAM)  Approximately 18,432 bits of distributed, 10 ns SRAM that can be configured as single- or dual-port, synchronous or asynchronous memory for FIFOs, scratch pads and lookup tables without consuming separate logic resources.
• High-Speed Performance  Series-level system speeds to 100 MHz with array multipliers exceeding 50 MHz and internal tri-state capability in each cell for fast arithmetic and data-path operations.
• I/O and Signal Support  193 general-purpose I/Os; the AT40K family provides PCI-compliant I/O capability and programmable output drive, with 3V/5V signaling options across the series.
• Clocking  Up to 8 global clocks with low-skew distribution, programmable edge transitions, and distributed clock shutdown for power management; includes additional dedicated PCI clocks at the family level.
• In-System Reconfigurability  Cache Logic dynamic full/partial re-configurability permits in-system updates without loss of data; supports serial and parallel reprogramming modes for adaptive designs.
• Package and Power  240-BFQFP (supplier package: 240-PQFP 32×32), surface-mount; nominal supply voltage 4.75 V to 5.25 V, commercial temperature grade 0 °C to 70 °C.
• Compliance  RoHS compliant.
• Design Ecosystem (Series-Level)  The AT40K family integrates with industry-standard design tools and automatic component generators to accelerate synthesis, placement & routing, and reusable IP creation.

Typical Applications

• Digital Signal Processing (DSP)  Implements FIR filters, FFTs and other arithmetic-intensive blocks using the array multipliers and distributed SRAM for coefficient storage and high-throughput datapaths.
• Video and Multimedia Acceleration  Supports computational blocks for compression, decompression and transforms where on-chip memory and fast multipliers reduce system latency.
• Custom Hardware Acceleration / Coprocessor  Acts as a reprogrammable coprocessor to offload compute-intensive tasks from a host processor, leveraging the device’s logic density and embedded RAM.
• PCI-Enabled Systems  Family-level PCI-compliant I/O capability combined with dedicated PCI clocks makes the device a fit for PCI-interface logic and peripheral designs.

Unique Advantages

• Flexible On-Chip Memory:  Distributed 10 ns SRAM provides up to 18,432 bits of embedded memory configurable as single- or dual-port blocks, reducing the need for external RAM and simplifying board design.
• Reconfigurability In-System:  Cache Logic dynamic full/partial reconfiguration allows design updates and coefficient changes in-system via serial or parallel modes without losing stored data.
• Multi-Clock Architecture:  Eight global clocks and additional dedicated PCI clocks enable low-skew clocking and independent clock domain control for complex system designs.
• Proven Design Tool Support:  Integration with industry-standard synthesis and simulation tools and automatic component generators accelerates development and IP reuse.
• Compact, Surface-Mount Package:  240-pin BFQFP package (surface mount) delivers substantial I/O and logic density for space-constrained boards while maintaining easy PCB assembly.
• Commercial-Grade Reliability:  Rated for 0 °C to 70 °C operation and RoHS compliant for mainstream commercial applications.
