AT40K20LV-3DQC

The AT40K20LV-3DQC is an SRAM-based FPGA from Microchip Technology in the AT40K/AT40KLV family, offering 1,024 logic elements and approximately 30,000 usable gates. It combines distributed, fast embedded SRAM with a reconfigurable logic fabric and a 208-pin surface-mount package for compact, mid-density designs.

Designed for high-performance logic acceleration and DSP-style co-processing tasks, this device suits commercial embedded systems that require on-chip RAM, flexible I/O counts, and system-level reconfigurability.

Key Features

• Logic Capacity  1,024 logic elements (1,024 registers) and approximately 30,000 gates provide mid-range density for control, signal processing, and glue-logic functions.
• Embedded Memory (FreeRAM)  Approximately 8,192 bits of distributed on-chip RAM with 10 ns access time; supports flexible single/dual-port and synchronous/asynchronous RAM configurations for FIFOs, scratch pads and buffering.
• High-Speed Operation  System speeds to 100 MHz and array multipliers rated for >50 MHz (series characteristic) enable accelerated arithmetic and DSP functions.
• Global Clocking  Eight global clock networks with low-skew distribution, programmable edge transitions and distributed clock shutdown for power management and timing control.
• I/O and Package  161 I/O pins in a 208-BFQFP surface-mount package (supplier package: 208-PQFP, 28×28). I/Os in the series support PCI-compliant signaling characteristics and 3 V/5 V capability (series detail).
• Power and Environmental  Nominal voltage supply 3.0 V to 3.6 V; commercial operating temperature range 0 °C to 70 °C. RoHS compliant and surface-mount for automated assembly.
• Reconfigurability and System Integration  Cache Logic dynamic partial/full re-configurability (series feature), internal tri-state capability in each cell, and pin-compatible package options to simplify migration and board-level substitution.
• Industry Design Tool Support  Series provides integration with industry-standard design and synthesis tools, enabling timing-driven placement, routing and reuse of automatic component generators.

Typical Applications

• DSP and Co-processor Acceleration  Used as a coprocessor to implement computation-intensive arithmetic like FIR filters, FFTs and vector multipliers to offload processors and speed signal processing tasks.
• Video and Multimedia Processing  Implements accelerators for video compression/decompression, DCT/IDCT, and other multimedia functions using the device’s embedded RAM and array multiplier features.
• Encryption & Security Engines  Deploys custom encryption, hashing and convolution functions where reconfigurable logic and on-chip memory enable algorithm updates and optimization.
• Custom Control & Glue Logic  Mid-density logic for interface bridging, protocol adaptation, and board-level control where compact packaging and abundant I/O are required.

Unique Advantages

• Flexible On-chip Memory: The device’s distributed 10 ns FreeRAM lets you implement multiple independent RAM functions without consuming separate logic resources.
• Reconfigurable In-System Capability: Series Cache Logic supports full or partial reconfiguration in-system, enabling adaptive designs and fast updates of algorithm coefficients.
• Balanced Performance and Density: With 1,024 logic elements and ~8,192 bits of RAM, the device provides a mid-range integration point for DSP and control tasks without excessive board area.
• Deterministic Clocking: Eight global clocks and low-skew distribution simplify multi-clock designs and timing management across the fabric.
• Package and Assembly Friendly: Surface-mount 208-pin BFQFP/PQFP package supports automated assembly and a compact board footprint for commercial applications.
• Toolchain Interoperability: Integration with industry-standard synthesis and simulation tools streamlines design entry, verification and migration across projects.
