AT40K05-2BQC

The AT40K05-2BQC is an SRAM-based FPGA from Microchip Technology’s AT40K family, featuring 256 logic elements and approximately 2,048 bits of distributed on-chip RAM. This commercial‑grade, surface‑mount device in a 144‑LQFP (20×20) package targets embedded designs that require reconfigurable logic, on-chip memory, and flexible I/O in a 5 V supply environment.

As part of the AT40K series, the device offers high-speed architecture features—including fast SRAM and support for array multipliers—making it suitable for functions such as DSP acceleration, coprocessing tasks, and general-purpose embedded logic implementation.

Key Features

• Logic Resources — 256 logic elements (cells) providing the basic fabric for combinational and sequential logic; referenced family register count aligns with 256 registers.
• Embedded Memory (FreeRAM) — Approximately 2,048 bits of distributed, 10 ns programmable SRAM that can be implemented as single- or dual-port, synchronous or asynchronous RAM blocks for FIFOs, scratch pads and small buffers.
• Performance — Series-level architecture supports system speeds to 100 MHz and array multipliers greater than 50 MHz; 10 ns SRAM timing supports fast local storage and access.
• I/O — 114 user I/Os in a 144‑LQFP package with programmable output drive; suitable for dense peripheral interfacing on a single chip.
• Clocking and Timing — Up to 8 global clocks for low-skew distribution and flexible edge selection; includes distributed clock shutdown capability for power management.
• Reconfigurability — Series Cache Logic capability for dynamic partial or full reconfiguration in-system, enabling adaptive design updates and rapid algorithm changes.
• Power and Supply — Designed for a 5 V supply range of 4.75 V to 5.25 V appropriate for 5 V system environments.
• Package and Mounting — 144‑LQFP (20×20) surface-mount package for standard PCB assembly.
• Operating Range and Grade — Commercial grade with operating temperature range 0 °C to 70 °C.
• Regulatory — RoHS compliant.

Typical Applications

• Digital Signal Processing (DSP) — Implement FIR filters, FFTs and array multipliers using the device’s embedded SRAM and fast multiplier-friendly fabric for media and communications processing.
• Coprocessor / Accelerator — Offload computation‑intensive tasks from a host CPU by mapping arithmetic and control logic into the FPGA’s logic elements and on-chip RAM.
• Embedded Control and Glue Logic — Consolidate interface logic, state machines and peripheral control in a single 144‑LQFP FPGA to simplify board-level design.
• Adaptive or Updatable Systems — Use in-system reconfiguration capabilities to update algorithms or parameters without removing the device from the board.

Unique Advantages

• Compact, reconfigurable logic and RAM: 256 logic elements plus approximately 2,048 bits of distributed SRAM let you implement control logic and local memory without external components.
• High-speed building blocks: Series architecture supports system speeds to 100 MHz and 10 ns SRAM, enabling responsive logic and fast local data paths.
• Flexible clocking: Eight global clocks with low skew and programmable edges simplify synchronous design and allow optimized timing across the fabric.
• In-system adaptability: Cache Logic reconfiguration lets you update or partially reconfigure designs in-system for rapid iteration or field updates.
• Standard packaging and mounting: 144‑LQFP surface‑mount package fits common PCB assembly processes while providing 114 I/Os for dense connectivity.
• Compliance and supply readiness: RoHS compliance and a defined 4.75–5.25 V supply range make the device suitable for established 5 V commercial system designs.
