AT40K20LV-3BQC

The AT40K20LV-3BQC from Microchip Technology is an SRAM-based field programmable gate array (FPGA) in a 144-LQFP (20×20) package. It delivers reprogrammable logic with embedded RAM and multiple global clocks, targeted at designs that need flexible, in-system reconfigurability and DSP-style coprocessing.

This device is suitable for commercial-grade embedded applications requiring up to 30,000 gates of logic, 1,024 logic elements, and 8,192 bits of on-chip RAM, operating from 3.0 V to 3.6 V and within a 0 °C to 70 °C temperature range.

Key Features

• Core Performance — Family-level capabilities include system speeds to 100 MHz and array multipliers >50 MHz; the device provides internal tri-state capability inside each cell for flexible routing and logic implementation.
• On-chip Memory (FreeRAM) — 8,192 bits of distributed SRAM on this device (approximately 8 Kbits) with 10 ns access capability in the AT40K/AT40KLV family, enabling single- or dual-port, synchronous/asynchronous memory structures without consuming logic resources.
• Logic Density — 1,024 logic elements (cells) and approximately 30,000 usable gates for mid-range combinational and sequential designs.
• I/O and Interface — 114 I/O pins on the 144-LQFP package; family features include PCI-compliant I/O options and programmable output drive characteristics (as described in the series documentation).
• Clocking — Family-level support for up to 8 global clocks with low-skew distribution and programmable edge transitions for synchronous design control.
• Package and Mounting — 144-LQFP (20×20) surface-mount package, RoHS compliant, suitable for standard PCB assembly processes in commercial applications.
• Power and Environmental — Supply voltage range 3.0 V to 3.6 V; operating temperature range 0 °C to 70 °C (commercial grade).
• Reconfigurability — Series-level Cache Logic capability for dynamic full/partial in-system reconfigurability and unlimited re-programmability via serial or parallel modes.

Typical Applications

• DSP Coprocessor — Implement FIR filters, FFTs, convolvers and other arithmetic accelerators that augment a host processor for multimedia and signal-processing tasks.
• Video and Image Processing — Use array multipliers and distributed SRAM to accelerate video compression/decompression and related transforms (e.g., DCT).
• Security and Encryption — Deploy configurable logic to implement encryption engines and related high-throughput arithmetic functions.
• Custom I/O and Protocol Bridging — Leverage the device’s programmable I/O and on-chip RAM for protocol adaptation, buffering and custom interface logic.

Unique Advantages

• Reconfigurable On-board Memory: Embedded distributed SRAM (8,192 bits) provides flexible single/dual-port memory without consuming logic elements, simplifying FIFO and scratch-pad designs.
• Dynamic In-System Reconfiguration: Cache Logic and unlimited reprogramming modes allow partial or full reconfiguration in-system, enabling adaptive designs and rapid updates.
• Balanced Mid-range Density: Approximately 30,000 gates and 1,024 logic elements offer a balance between capacity and cost for mid-complexity designs.
• Commercial-grade Form Factor: 144-LQFP surface-mount package with 114 I/Os supports dense PCB layouts while remaining RoHS compliant.
• Clocking and Performance Features: Multiple global clocks and family-level support for low-skew distribution and programmable edges help simplify timing across synchronous designs.
• Toolchain and Migration Support: The series integrates with industry-standard design flows and provides automatic component generators and IP cores to accelerate development and migration to gate arrays for production.
