AT40K05AL-1BQU

The AT40K05AL-1BQU is a commercially graded, SRAM-based Field Programmable Gate Array (FPGA) from the AT40KAL family. This device provides a compact, surface-mount 144-LQFP (20×20) package and is designed for high-performance, reconfigurable logic tasks in embedded and DSP-assisted systems.

With 256 logic elements, approximately 10,000 gates and 2,048 bits of distributed embedded RAM, the AT40K05AL-1BQU targets applications that require flexible on-chip memory, fast arithmetic blocks, and a programmable I/O set. It supports a 3.0 V–3.6 V supply range, operates from 0 °C to 70 °C, and is RoHS compliant.

Key Features

• Core Capacity: 256 logic elements and 10,000 gates provide a mid-density FPGA fabric suitable for control, interface, and DSP offload functions.
• Distributed Embedded RAM (FreeRAM™): Approximately 2,048 bits of on-chip RAM supporting single- or dual-port, synchronous or asynchronous 10 ns SRAM functions for FIFOs and scratchpad memory.
• High-Speed Arithmetic: Family-level array multipliers and architecture support fast vector and multiplier implementations; system speeds up to 100 MHz are documented for the series.
• I/O and Compatibility: 114 I/O pins in this package; family-level PCI-compliant I/O architecture and programmable output drive options are described in the series documentation.
• Reconfiguration (Cache Logic): Series-level Cache Logic enables dynamic full/partial reconfigurability in-system without loss of data, facilitating adaptive or updateable designs.
• Clocking: Series supports multiple global clock resources and low-skew distribution (eight global clocks documented for the family), enabling synchronous design partitioning and clock management.
• Package & Mounting: 144-LQFP (20×20) surface-mount package for compact PCB integration.
• Power & I/O Voltage: Supply voltage range 3.0 V to 3.6 V; family documentation notes 5 V I/O tolerance for compatible I/O standards.
• Environmental & Grade: Commercial temperature rating (0 °C to 70 °C) and RoHS compliant.

Typical Applications

• DSP and Coprocessing: Use as a coprocessor to implement arithmetic-intensive functions such as FIR filters and FFTs, leveraging on-chip RAM and array multiplier architecture.
• Video and Multimedia Processing: Implement video processing blocks, compression/decompression pre- or post-processing, and fixed-point arithmetic accelerators.
• Interface Bridging and I/O Management: Handle protocol interfacing, GPIO expansion, and custom I/O timing with programmable output drive and flexible I/O count.
• Embedded Control and State Machines: Implement control logic, sequencers, and system glue functions where reconfigurable logic and small embedded memories simplify design partitioning.

Unique Advantages

• Flexible On-Chip Memory: Distributed FreeRAM™ lets you instantiate multiple small SRAM blocks without consuming general logic resources.
• Reconfigurable Architecture: Cache Logic enables partial or full in-system reconfiguration for adaptive designs or quick updates without losing stored data.
• Balanced Density and Performance: 256 logic elements and 10,000 gates deliver a balanced mix of capacity and performance for mid-range FPGA tasks.
• Compact, Surface-Mount Packaging: 144-LQFP (20×20) fits space-constrained PCBs while providing ample I/O for peripheral interfacing.
• Commercial-Grade, RoHS Compliant: Designed for commercial temperature ranges and compliant with RoHS environmental requirements.
