AT40K20-2FQC

The AT40K20-2FQC is an SRAM-based Field Programmable Gate Array (FPGA) from Microchip Technology's AT40K family. It delivers a balanced mix of logic capacity, embedded memory and I/O density for commercial embedded systems that require reprogrammable logic and on-chip RAM.

Built on the AT40K architecture, the device incorporates distributed 10 ns SRAM (FreeRAM), Cache Logic in-system reconfigurability and an array structure optimized for high-speed arithmetic. Typical use cases include DSP acceleration, protocol bridging and high-performance control logic in commercial applications.

Key Features

• Logic Capacity  1,024 logic elements (cells) suitable for medium-complexity designs and control logic implementation.
• Embedded Memory (FreeRAM)  8,192 bits of distributed on-chip SRAM with 10 ns access time; supports flexible single/dual-port, synchronous or asynchronous configurations as provided by the AT40K FreeRAM architecture.
• Performance  System speeds to 100 MHz and array multipliers exceeding 50 MHz (family-level characteristics) enable signal-processing and arithmetic functions with low latency.
• I/O Density & Compatibility  256 user I/Os; the AT40K family provides PCI-compliant I/O options and programmable output drive with 3V/5V capability (this AT40K device uses a 5 V supply range of 4.75 V to 5.25 V).
• Clocking  Up to 8 global clocks with low-skew distribution, programmable edge transitions and distributed clock shutdown control for power management (family-level features).
• In-System Reconfigurability  Cache Logic enables full or partial in-system reconfiguration and unlimited reprogramming via serial or parallel modes for adaptive designs and rapid algorithm updates.
• Packaging & Mounting  304-pin BFQFP (supplier package: 304-PQFP 40 × 40 mm), surface-mount device suitable for standard PCB assembly processes; commercial-grade operating range 0 °C to 70 °C.
• Standards & Compliance  RoHS‑compliant commercial FPGA; designed to integrate with industry-standard design flows and IP cores (family-level tool support).

Typical Applications

• Digital Signal Processing (DSP) / Coprocessing  Implement FIR filters, FFTs and other arithmetic accelerators using the device's distributed RAM and fast array multipliers for multimedia and communication systems.
• Protocol Bridging & High-speed Interfaces  Use the 256 I/Os and family PCI-compliant I/O capability to implement interface logic, protocol translation and custom I/O handling in commercial systems.
• Video & Multimedia Processing  Leverage on-chip multipliers and reconfigurable Cache Logic to update coefficients and processing blocks in-system for codecs, image processing and streaming applications.
• Security & Encryption Engines  Deploy reconfigurable logic and embedded RAM to implement cryptographic accelerators and key-management components with in-field updateability.

Unique Advantages

• Configurable Embedded RAM  8,192 bits of distributed 10 ns SRAM (FreeRAM) gives designers flexible, high-performance on-chip memory without consuming additional logic resources.
• Deterministic Arithmetic Performance  Array multipliers and an architecture optimized for direct cell-to-cell connections enable high-speed arithmetic operations for DSP workloads.
• In-System Flexibility  Cache Logic supports partial and full reconfiguration while preserving data, enabling adaptive systems and rapid field updates.
• Comprehensive Clocking  Eight global clocks and programmable clock controls help achieve low-skew, timing-driven designs and fine-grained power management.
• Broad I/O and Packaging  256 I/Os in a 304-pin BFQFP package provide a practical balance of pin count and board-level form factor for commercial embedded designs.
• Commercial-Grade & RoHS Compliant  Designed for 0 °C to 70 °C operation and RoHS compliance for standard commercial deployments.
