AT40K20-2BQI

The AT40K20-2BQI is an SRAM-based field programmable gate array from Microchip Technology designed for mid-range gate-count applications. Built on the AT40K family architecture, it combines reconfigurable logic, distributed on-chip SRAM, and dedicated clocking to support computation-intensive tasks and adaptive designs.

This device targets applications such as DSP coprocessing, video and multimedia processing, and general-purpose embedded logic in industrial environments. Key value propositions include fast on-chip memory access, dynamic reconfigurability, and a robust industrial-grade temperature and supply specification for reliable deployment.

Key Features

• Core Performance — Ultra high-performance series architecture with documented system speeds to 100 MHz and array multipliers capable of >50 MHz; cells include internal tri-state capability for flexible routing and logic implementation.
• Logic Capacity — 1,024 logic elements (cells) supporting approximately 30,000 usable gates, suitable for mid-range integration of combinational and sequential logic.
• Embedded Memory (FreeRAM) — 8,192 bits of distributed, 10 ns programmable SRAM independent of logic cells, usable as single-port or dual-port, synchronous or asynchronous memory for FIFOs, scratch pads and temporary storage.
• I/O and Voltage — 114 general-purpose I/O pins and a 5 V-class supply range (4.5 V to 5.5 V), enabling use in 5 V systems while supporting flexible I/O drive options provided by the series architecture.
• Clocking — Dedicated global clock resources (8 global clocks available in the family) for low-skew distribution and configurable edge transitions to support timing-sensitive designs.
• Reconfigurability (Cache Logic) — Series-level support for dynamic full/partial in-system reconfiguration, enabling adaptive designs and rapid updates without losing stored data in specified modes.
• Package & Mounting — 144-LQFP (20×20) surface-mount package; industrial-grade construction and operating range.
• Environmental & Reliability — RoHS-compliant and specified for industrial operating temperatures from −40 °C to 85 °C.

Typical Applications

• DSP Coprocessing — Implement FIR filters, FFTs, convolvers and interpolators to offload computation from a host processor and accelerate signal-processing tasks.
• Video and Multimedia Processing — Use on-chip multipliers and distributed RAM to handle video compression, decompression and other media transforms that require fast, low-latency arithmetic.
• Data Buffers and FIFOs — Leverage the 8,192 bits of FreeRAM for temporary storage, buffering, and data-path staging in communication and streaming applications.
• Industrial Embedded Control — Deploy as configurable logic for motor control, sensor aggregation, and protocol bridging within the −40 °C to 85 °C operating range.

Unique Advantages

• Flexible on-chip memory: Distributed 10 ns SRAM (FreeRAM) provides single/dual-port, synchronous/asynchronous memory independent of logic cells, reducing external RAM needs and lowering BOM complexity.
• Reconfigurable design flow: Cache Logic dynamic reconfiguration enables partial or full in-system updates for adaptive algorithms and fast iteration during development and deployment.
• Deterministic clocking: Multiple global clocks deliver low-skew distribution and configurable edges, simplifying timing closure for high-speed designs.
• Industrial reliability: Surface-mount 144-LQFP packaging, industrial temperature rating (−40 °C to 85 °C) and RoHS compliance support long-term use in industrial applications.
• Balanced integration: Combination of ~30,000 gates, 1,024 logic elements and 114 I/Os provides a mid-range solution that balances logic density and I/O count for embedded systems.
• Design ecosystem compatibility: Series-level documentation highlights compatibility with industry-standard synthesis and simulation tools to streamline integration into existing toolchains.
