AT40K20-2CQC

The AT40K20-2CQC is an SRAM-based FPGA from Microchip Technology’s AT40K/AT40KLV family, offering 1,024 logic elements and 8,192 bits of distributed on-chip RAM in a 160-BQFP surface-mount package. Designed for commercial-temperature applications, this device targets high-performance programmable logic tasks where on-chip memory, flexible I/O and reconfigurability are required.

Its architecture includes fast 10 ns distributed SRAM, support for multiple clock domains, and PCI-compliant I/O characteristics at 3V/5V signaling levels, making it suitable for compute- and I/O-intensive embedded designs and DSP-oriented coprocessor roles described in the family datasheet.

Key Features

• Core Logic — 1,024 logic elements (cells) delivering approximately 30,000 usable gates for implementing combinational and sequential logic.
• On-Chip Memory (FreeRAM) — 8,192 bits of distributed, 10 ns SRAM that can be configured as single-port or dual-port, synchronous or asynchronous memory for FIFOs, scratch pads and other buffering needs.
• Performance — Family-level performance indicators include system speeds to 100 MHz and array multipliers >50 MHz, with 10 ns flexible SRAM and internal tri-state capability in each cell.
• I/O — 130 I/O pins with 3V/5V capability and programmable output drive; I/O counts in the family support PCI-compliant implementations.
• Clocking — Up to eight global clocks with low-skew distribution, programmable edge transitions and distributed clock shutdown for power management (family feature).
• Package & Mounting — 160-BQFP surface-mount package (supplier device package: 160-PQFP 28×28) for high pin-count board designs.
• Power & Temperature — 5 V supply range (4.75 V to 5.25 V) and commercial operating temperature range of 0 °C to 70 °C.
• Standards & Tools — Family-level support for standard FPGA design flows and IP cores to accelerate implementation of DSP and system functions (as documented in the series datasheet).
• Compliance — RoHS-compliant device.

Typical Applications

• DSP Coprocessors — Implement FIR filters, FFTs, convolvers and other arithmetic functions using the device’s distributed RAM and array multiplier architecture for accelerated signal processing.
• Multimedia & Video Processing — Use on-chip memory and fast multiply structures to handle transformations and compression tasks in video and image pipelines.
• Embedded I/O Expansion — High I/O count and programmable output drive make the device suitable for bridging, protocol adaptation and custom peripheral interfaces in embedded systems.
• Adaptive & Reconfigurable Designs — Leverage the family’s Cache Logic dynamic partial/full reconfigurability and unlimited reprogramming modes to update algorithms or coefficients in-system.

Unique Advantages

• Flexible Embedded RAM: Distributed 10 ns FreeRAM can be instantiated as single- or dual-port memory without consuming separate logic macros, enabling efficient buffering and state storage.
• High I/O Density: 130 I/O pins with 3V/5V capability and programmable drive simplify interfacing to a wide range of legacy and modern peripherals.
• Reconfigurability: Series-level Cache Logic support for in-system partial or full reconfiguration enables adaptive designs and fast updates without losing retained data.
• Fast Arithmetic Support: Array multiplier architecture and high-speed internal routing support computationally intensive functions for DSP and multimedia workloads.
• Standard Package for Dense Designs: 160-BQFP (160-PQFP 28×28 footprint) balances pin count and board routing for compact, high-density implementations.
• Commercial-Grade Reliability: Specified for 0 °C to 70 °C operation with a defined 5 V supply range, suitable for mainstream embedded and commercial applications.
