AT40K20AL-1DQI

The AT40K20AL-1DQI is an SRAM-based FPGA in the AT40KAL family, designed for high-performance, reconfigurable digital logic and DSP-oriented functions. It provides on-chip distributed RAM, a dense I/O complement, and architecture-level features intended for compute-intensive and interface-rich applications.

Targeted use cases include coprocessor acceleration, signal processing blocks and high-density I/O designs where in-system reprogramming, embedded RAM and fast arithmetic resources improve performance and design flexibility.

Key Features

• Core Performance – Family-level system speeds to 100 MHz and array multipliers exceeding 50 MHz, with internal tri-state capability in each cell and a total of approximately 30,000 gates for complex logic implementations.
• Logic Resources – 1,024 logic elements (cells) suitable for medium-density programmable logic functions.
• Embedded Memory (FreeRAM) – Distributed, flexible 10 ns SRAM totaling 8,192 bits on this device; family support for 2,048–18,432 bits of distributed SRAM and single/dual-port synchronous/asynchronous configurations.
• I/O and Clocking – 161 I/O pins with family-level PCI-compliant I/O options, programmable output drive and pin-locking capability; 8 global clocks plus 4 dedicated PCI clocks and features for low-skew distribution and clock shutdown.
• Reconfiguration – Cache Logic capability for dynamic full or partial in-system reconfiguration and unlimited reprogramming via serial or parallel modes to enable adaptive designs and fast updates.
• Packaging and Mounting – Surface-mount 208-BFQFP package (supplier reference: 208-PQFP 28×28) for board-level integration.
• Power and I/O Levels – Supply voltage range 3.0 V to 3.6 V (family documentation indicates 3.3 V designs supported); device supports 5 V I/O tolerance per family-level information.
• Environmental and Grade – Industrial grade device with operating temperature range –40 °C to 85 °C and RoHS compliance.
• Toolchain and Integration – Family-level integration with industry-standard design tools for synthesis, placement, routing and back-annotation to streamline development and migration.

Typical Applications

• DSP and Accelerator Blocks – Implement adaptive FIR filters, FFTs, convolvers and other arithmetic-heavy blocks using the device’s array multipliers and distributed SRAM.
• Video and Multimedia Processing – Use embedded RAM and fast multipliers for real-time video compression/decompression, DCT implementations and related processing chains.
• Communications and Networking – High I/O density and programmable I/O drive make the device suitable for protocol interfaces, buffering and medium-speed packet processing.
• Industrial Control and Automation – Industrial temperature range and reprogrammability support evolving control logic, sensor interfacing and machine-automation tasks.
• In-System Reconfiguration and Prototyping – Cache Logic reconfiguration enables rapid design iterations, partial updates and adaptive feature deployment without losing on-chip state.

Unique Advantages

• Dynamic Reconfiguration: Cache Logic enables full or partial in-system reconfiguration so you can update or adapt designs without a full device rewrite.
• Flexible On-Chip RAM: Distributed 10 ns SRAM (8,192 bits on this device) supports single- or dual-port, synchronous or asynchronous RAM functions for FIFOs, scratch pads and coefficient storage.
• Fast Arithmetic Resources: Eight-sided core cell topology (family-level) and array multipliers provide fast vector and array multiplication with minimal external busing.
• High I/O Count and Programmability: 161 I/O pins with programmable drive and family-level PCI-compliant options facilitate dense, high-speed external interfacing and pin-locking.
• Industrial Operating Range: Rated for –40 °C to 85 °C and RoHS compliant, supporting deployment in temperature-challenging environments.
• Package Options for Board Integration: Surface-mount 208-BFQFP (208-PQFP 28×28) simplifies PCB layout for medium-pin-count, performance-oriented designs.
