AT40K05AL-1AQC

The AT40K05AL-1AQC is a commercial-grade, SRAM-based Field Programmable Gate Array (FPGA) in the AT40KAL family, delivered in a 100-TQFP (14×14) surface-mount package. It provides approximately 2,048 bits of embedded RAM, 256 logic elements, and 78 user I/O pins, making it suitable for medium-complexity digital designs that require on-chip memory and runtime reconfigurability.

As a member of the AT40KAL family, the device is built for high-performance, reconfigurable logic tasks and integration with standard FPGA toolflows. Typical uses include coprocessing, signal processing blocks, and application-specific control logic where compact packaging and moderate I/O counts are required.

Key Features

• Core Performance – Family-level capabilities include system speeds to 100 MHz and array multipliers enabling high-speed arithmetic; the device implements 256 logic elements for combinational and sequential logic.
• Embedded Memory (FreeRAM) – Approximately 2,048 bits of distributed, 10 ns SRAM are available on-chip for FIFOs, scratch pads, or coefficient storage; memory can be instantiated as single- or dual-port, synchronous or asynchronous where supported by the family architecture.
• I/O and Package – 78 user I/O pins are available on a 100‑TQFP (14×14) surface-mount package, providing a compact footprint for board-level integration.
• Clocking – The AT40KAL family provides advanced clock distribution features (including multiple global clocks) to support low-skew signaling and synchronous designs.
• Voltage and Mounting – Operates from 3.0 V to 3.6 V supply and is implemented as a surface-mount device; the family references a 3.3 V nominal supply and 5 V I/O tolerance where applicable.
• Operating Grade – Commercial-grade device with an operating temperature range of 0 °C to 70 °C and RoHS-compliant materials.

Typical Applications

• Digital Signal Processing (DSP) – Implement adaptive FIR filters, FFTs, or vector multipliers using the device’s embedded RAM and array multiplier architecture for offloading compute-intensive tasks.
• Multimedia and Compression – Support for convolution, DCT, and related algorithms enables roles in video compression/decompression and image processing pipelines.
• Coprocessor and Accelerator – Use as a programmable coprocessor for processor-based systems to accelerate arithmetic and custom datapaths.
• Embedded Control and Glue Logic – Compact package and moderate I/O count suit the device to board-level glue logic, protocol adaptation, and control functions in commercial electronics.

Unique Advantages

• Reconfigurability with Cache Logic: Family-level dynamic partial/full reconfiguration enables updates and design changes in-system without losing data, supporting adaptive designs.
• Fast On-chip RAM: Distributed 10 ns FreeRAM allows low-latency storage for FIFOs, buffers, and coefficients directly inside the FPGA fabric.
• Compact, Surface-mount Package: 100‑TQFP (14×14) package supports compact PCB layouts while exposing 78 I/O for board-level connectivity.
• Toolflow Integration: The AT40KAL family integrates with industry-standard FPGA design tools for synthesis, placement, and routing to accelerate development cycles.
• Commercial Temperature and RoHS Compliance: Designed for commercial applications with a 0 °C to 70 °C rating and RoHS-compliant construction.
