AT40K20AL-1BQU

The AT40K20AL-1BQU is an SRAM-based FPGA from the AT40KAL family, manufactured by Microchip Technology. It provides a mid-range programmable fabric with 1,024 logic elements, approximately 8,192 bits of distributed on-chip RAM, and up to 114 I/O pins in a 144‑LQFP surface-mount package.

Designed for high-performance, reconfigurable logic tasks, the device targets DSP-accelerated processing and multimedia functions where on-chip RAM, fast clocking and in-system reconfigurability are beneficial. Its combination of distributed 10 ns SRAM, cache-logic reconfiguration capability and array multiplier support addresses use cases that require adaptable arithmetic and memory resources.

Key Features

• Core Logic  1,024 logic elements (cells) delivering approximately 30,000 equivalent gates for mid-range programmable logic integration.
• Embedded Memory (FreeRAM)  Approximately 8,192 bits of distributed SRAM usable as single/dual-port, synchronous or asynchronous memory with 10 ns access characteristics.
• I/O and Package  114 I/O pins in a 144‑LQFP (20 × 20 mm) surface-mount package, supporting flexible pin assignments for board-level integration.
• Clocking  Architecture includes support for global clock resources (8 global clocks as specified for the AT40KAL family) enabling low-skew clock distribution and controlled clock management.
• Reconfigurability (Cache Logic)  Supports dynamic full or partial in-system reconfiguration (Cache Logic), enabling unlimited re-programmability via serial or parallel modes for adaptive designs.
• On-chip Multiplier Support  Cell-to-cell connections and array multiplier structures enable efficient implementation of arithmetic functions used in DSP and signal processing.
• Power and I/O Levels  Supply range 3.0 V to 3.6 V with documented 3.3 V operation; family-level documentation also indicates 5 V I/O tolerance where applicable.
• Commercial Grade & RoHS  Commercial temperature grade (0 °C to 70 °C) and RoHS compliant.

Typical Applications

• DSP and Coprocessor Acceleration  Implement FFTs, FIR filters and other arithmetic-heavy functions to offload processors and improve system throughput.
• Video and Multimedia Processing  Use embedded SRAM and array multipliers for tasks such as compression, decompression, and format-specific transforms.
• Encryption and Signal Processing  Implement custom crypto engines, convolvers and other high-speed data-path logic where reconfigurability enables rapid algorithm updates.
• Adaptive and Reconfigurable Systems  Systems that benefit from partial or full in-field reconfiguration for feature updates or runtime optimization.

Unique Advantages

• Flexible On-chip RAM  Distributed FreeRAM architecture provides low-latency, 10 ns accessible memory without consuming standard logic resources, simplifying FIFO and scratch-pad implementations.
• In-System Reconfigurability  Cache Logic enables dynamic partial or full reconfiguration, allowing design adaptation and rapid updates without removing the device from the board.
• Efficient Arithmetic Resources  Built-in array multiplier topology and dense cell interconnects allow compact, high-speed implementation of DSP kernels.
• Board-level Integration  144‑LQFP surface-mount package with 114 I/Os supports straightforward PCB integration and pin assignments for a variety of systems.
• Commercial Temperature and RoHS Compliance  Designed for commercial deployments with documented 0 °C to 70 °C operation and RoHS conformity for modern manufacturing.
