AT40K20-2CQI

The AT40K20-2CQI is an SRAM-based Field Programmable Gate Array from Microchip Technology in the AT40K family. It combines roughly 1,024 logic elements with approximately 8,192 bits of distributed on-chip RAM and a 130-pin I/O interface in a 160-pin BQFP package.

Designed for high-performance, reconfigurable logic tasks, this device targets applications that require local memory, multiple clock domains and flexible I/O while operating from a 4.5 V to 5.5 V supply across an industrial temperature range (‑40 °C to 85 °C).

Key Features

• Core Architecture  SRAM-based FPGA core with 1,024 logic elements (cells) and an architecture that supports array multipliers and internal tri-state capability in each cell.
• On-chip Memory (FreeRAM)  Approximately 8,192 bits of distributed 10 ns SRAM that can be configured as single- or dual-port, synchronous or asynchronous memory for FIFOs, scratch pads and other local storage.
• Performance  System operation up to 100 MHz and array multipliers capable of >50 MHz; includes 10 ns flexible SRAM timing for fast local memory access.
• I/O  130 I/O pins with the AT40K family offering PCI-compliant I/O options and 3V/5V capability in the series; programmable output drive and pin-locking facilitation.
• Clocking  Eight global clocks with low skew distribution, programmable edge transitions, distributed clock shutdown and additional dedicated PCI clocks in the family.
• Reconfigurability  Cache Logic functionality enabling dynamic full or partial in-system reconfiguration for adaptive designs and fast updates.
• Package & Mounting  160‑BQFP (supplier package listed as 160‑PQFP 28×28); surface-mount device suitable for standard PCB assembly.
• Environmental & Supply  Industrial grade operation from ‑40 °C to 85 °C, supply voltage 4.5 V to 5.5 V, and RoHS compliant.

Typical Applications

• DSP Acceleration / Coprocessor  Implement FIR filters, FFTs and other computation-intensive functions where on-chip RAM and array multipliers accelerate throughput.
• Video and Multimedia Processing  Support for fast vector multipliers and distributed memory makes the device suitable for video compression/decompression, convolution and related algorithms.
• Communications and PCI-based Systems  Family I/O capabilities include PCI-compliant interfaces for system-level interconnect and protocol bridging.
• Prototyping and Adaptive Systems  Dynamic partial/full reconfiguration (Cache Logic) lets designers update logic in-system for iterative development and adaptive algorithms.

Unique Advantages

• Embedded FreeRAM  Distributed 10 ns SRAM provides local memory without consuming logic resources, enabling efficient FIFOs and scratchpad implementations.
• Reconfigurable Cache Logic  In-system full or partial reconfiguration enables adaptive designs and fast vector/coefficient updates without halting other functions.
• Multi-clock Support  Eight global clocks and dedicated PCI clocks provide flexible, low-skew clock domains for complex designs.
• 5 V Supply and Industrial Temperature Range  Operates from 4.5 V to 5.5 V and across ‑40 °C to 85 °C, supporting industrial applications that require this supply and temperature window.
• Pin- and Package-flexible Family  Part of a family with multiple package options and pin-compatible choices, facilitating migration and board-level reuse.
• Design Ecosystem Compatibility  The AT40K family integrates with industry-standard design tools and automatic component generators to streamline synthesis and implementation.
