AT40K40-2DQI

The AT40K40-2DQI is an SRAM-based FPGA from the AT40K family, offering 2,304 logic elements, approximately 18,432 bits of distributed on-chip RAM, and 161 I/O pins in a 208-BFQFP package. It operates from a 4.5 V to 5.5 V supply and is specified for industrial temperature operation from -40 °C to 85 °C.

Designed for high-performance embedded and DSP-augmented systems, the device provides features such as fast on-chip SRAM, dedicated clock resources and in-system reconfigurability. Typical applications include coprocessor acceleration, multimedia processing, and other compute-intensive tasks where reprogrammable logic and embedded RAM accelerate algorithm execution.

Key Features

• Core Capacity  2,304 logic elements and a stated gate-equivalent figure of 50,000 gates provide capacity for medium-complexity FPGA designs.
• Embedded Memory (FreeRAM)  Approximately 18,432 bits of distributed, 10 ns SRAM usable in single- or dual-port configurations; memory is independent of logic resources to maximize flexibility.
• High-Speed Building Blocks  Series-level performance notes include system speeds to 100 MHz and array multipliers > 50 MHz, plus a 10 ns programmable SRAM access time for responsive data handling.
• I/O and Interface  161 I/O pins with 3V/5V capability and programmable output drive; the series supports PCI-compliant I/Os per datasheet guidance.
• Clocking  Eight global clocks with low-skew distribution, programmable edge transitions and distributed clock shutdown for power management.
• Reconfigurability  Cache Logic support for dynamic full or partial in-system reconfiguration with unlimited re-programmability via serial or parallel modes.
• Package & Mounting  208-BFQFP (supplier package 208-PQFP, 28 × 28) in a surface-mount format suitable for standard PCB assembly.
• Power & Environmental  5 V-class device operation with supply range 4.5 V to 5.5 V and industrial-grade operating temperature from -40 °C to 85 °C.
• Compliance  RoHS compliant.

Typical Applications

• Coprocessor Acceleration  Offload compute-heavy functions (FIR filters, FFTs, multipliers) to on-chip logic and RAM for higher system throughput.
• Multimedia Processing  Use the device’s array multipliers and distributed SRAM to implement video compression, decompression and other signal-processing kernels.
• High-Speed Embedded Systems  Deploy as a reconfigurable accelerator in DSP/processor-based platforms to implement arithmetic and control functions with low-latency on-chip memory access.
• PCI-Related Interfaces  Leverage the series’ PCI-compliant I/O capability and programmable output drive when integrating with PCI-based systems or legacy 3.3 V/5 V interfaces.

Unique Advantages

• Integrated On-Chip SRAM:  Approximately 18,432 bits of distributed FreeRAM that can be instantiated as single- or dual-port memory without consuming additional logic resources.
• Fast, Deterministic Performance:  Series-level system speeds to 100 MHz and 10 ns SRAM access provide deterministic timing for demanding signal-processing tasks.
• Flexible In-System Reconfiguration:  Cache Logic enables full or partial reconfiguration in-system via serial or parallel modes for adaptive designs and field updates.
• Industrial Operating Range:  Specified operation from -40 °C to 85 °C and RoHS compliance support deployment in industrial applications.
• Standard Surface-Mount Package:  208‑pin BFQFP (28 × 28 PQFP footprint) eases PCB design and assembly for space- and cost-constrained systems.
• 3V/5V I/O Flexibility:  I/O capability supports mixed-voltage interfacing and programmable output drive to simplify integration with existing boards and subsystems.
