AT40K40AL-1EQC

The AT40K40AL-1EQC is an SRAM-based, reprogrammable FPGA from the AT40KAL family designed for high-performance, mid-to-large gate-count designs. It combines 2,304 logic elements with approximately 18,432 bits of distributed on-chip RAM and a high I/O count to support computation-intensive and I/O-rich applications.

Built for applications requiring embedded memory, flexible reconfiguration and multiple clock domains, this commercial-grade device is suitable for DSP coprocessor roles, multimedia processing, and other systems that benefit from in-system reprogramming and fast on-chip RAM access.

Key Features

• Core Capacity  The device provides 2,304 logic elements (cells) and is specified at approximately 50,000 usable gates for mid-to-large designs.
• Embedded Memory (FreeRAM)  Approximately 18,432 bits of distributed 10 ns SRAM independent of logic cells; supports single/dual-port and synchronous/asynchronous configurations for FIFOs, scratch pads and more.
• Performance  System speeds up to 100 MHz with array multipliers exceeding 50 MHz and 10 ns flexible SRAM for fast local storage and arithmetic acceleration.
• I/O and PCI Compatibility  193 I/O pins with PCI-compliant I/O options, programmable output drive and fast array access for pin-locking and interface flexibility. Family supports up to 384 I/Os.
• Clocking  Eight global clocks with low-skew distribution, programmable rising/falling edge transitions, distributed clock shutdown and dedicated PCI clock resources.
• Dynamic Reconfiguration (Cache Logic)  Supports dynamic full/partial in-system reconfiguration with unlimited reprogramming via serial or parallel modes, enabling adaptive designs and fast updates.
• I/O Voltage and Tolerance  Operates from 3.0 V to 3.6 V supply and includes 5 V I/O tolerance as specified for the family.
• Package & Mounting  Surface-mount 240-BFQFP package (supplier package: 240-PQFP 32 × 32). RoHS compliant.
• Operating Range  Commercial-grade device rated for 0 °C to 70 °C ambient operation.
• Design Tool Ecosystem  Family-level support for industry-standard synthesis and verification flows and automatic component generators to accelerate development.

Typical Applications

• DSP Coprocessor and Accelerators  Implement FIR filters, FFTs, convolvers and other compute-intensive kernels using embedded multipliers and distributed SRAM for local data storage.
• Video and Multimedia Processing  Support video compression/decompression and related transforms (DCT, interpolation) where fast array multipliers and on-chip RAM reduce external memory dependence.
• Encryption and Signal Processing  Implement encryption cores and high-throughput signal-processing blocks leveraging reconfigurability and fast on-chip RAM.
• High I/O Interface Control  Use the large I/O count and PCI-compliant I/O capability for multi-channel interface bridging, protocol handling and system glue logic.

Unique Advantages

• Flexible On-Chip RAM  Distributed 10 ns SRAM that can be used independently of logic resources provides low-latency storage for FIFOs, buffers and coefficient storage.
• Reconfigurable In-System  Dynamic full or partial reconfiguration allows runtime updates and adaptive designs without losing data in configured regions.
• High I/O Count with PCI Options  193 I/Os and family PCI-compliant I/O capabilities simplify integration with host buses and high-pin-count systems.
• Multiple Global Clocks  Eight global clocks with programmable edges and shutdown provide flexible timing domains and power management options.
• Compact Surface-Mount Package  240-BFQFP surface-mount package supports dense board layouts while providing the pin count needed for complex designs.
• Industry Toolchain Support  Family-level compatibility with common synthesis and simulation flows reduces toolchain integration effort and shortens development cycles.
