AT40K05LV-3BQC

The AT40K05LV-3BQC is a commercial-grade, SRAM-based Field Programmable Gate Array (FPGA) in the AT40K/AT40KLV family. It combines a reconfigurable logic fabric with distributed on-chip SRAM and a broad I/O set to support embedded logic, DSP coprocessing and adaptive system functions.

Built for performance and in-system reconfigurability, the device targets applications that require compact, programmable logic with up to 114 I/Os, 2,048 bits of distributed RAM and support for 3.0–3.6 V supply operation in a 144-LQFP (20 × 20) surface-mount package.

Key Features

• Core Performance – Series-level system speeds to 100 MHz and array multipliers exceeding 50 MHz enable fast arithmetic and control operations suitable for DSP-style functions.
• Logic Capacity – 256 logic elements (cells) and approximately 10,000 usable gates provide a compact programmable fabric for glue logic, protocol handling and small to medium combinatorial/sequential designs.
• Embedded Memory (FreeRAM) – 2,048 bits of distributed 10 ns SRAM supporting single- or dual-port, synchronous or asynchronous operation, useful for FIFOs, scratch pads and coefficient storage without consuming logic resources.
• I/O and Drive – 114 I/Os in the 144-LQFP package with support for mixed-voltage operation noted in the family; programmable output drive and pin-locking capabilities are provided at the series level.
• Clocking – Family-level support for up to eight global clocks and four additional dedicated PCI clocks enables low-skew distribution and flexible clocking strategies for multiple clock domains.
• Reconfigurability – Cache Logic and QuickChange™ family features enable dynamic full or partial in-system reconfiguration and unlimited reprogramming via serial or parallel modes (series-level capability).
• Package & Mounting – 144-LQFP (20 × 20) surface-mount package for compact PCB integration; RoHS compliant.
• Electrical & Environmental – Supply voltage 3.0 V to 3.6 V and operating temperature range 0 °C to 70 °C for commercial applications.

Typical Applications

• DSP Coprocessing – Implement arithmetic-intensive functions such as FIR filters, FFT blocks and multipliers using the device’s array multipliers and distributed RAM for intermediate storage.
• Video and Multimedia Processing – Useful for accelerators in video compression/decompression and image processing where reconfigurable logic and fast, local memory simplify coefficient updates and algorithm changes.
• Encryption & Security – Deploy cryptographic cores and custom bit-level transforms leveraging the FPGA’s reprogrammability and on-chip RAM for key or state storage.
• Custom I/O and Protocol Bridging – Handle glue logic, protocol translation and custom peripheral interfacing with 114 I/Os in a compact LQFP footprint.

Unique Advantages

• Reconfigurable In-System – Series Cache Logic and QuickChange™ capabilities allow dynamic partial or full reconfiguration without losing stored data, enabling adaptive designs and field updates.
• Integrated Fast SRAM – Distributed 10 ns SRAM provides low-latency memory close to logic elements, reducing external memory dependence for small buffers and state storage.
• Compact, Surface-Mount Package – 144-LQFP (20 × 20) package supports high I/O count in a board-friendly, surface-mount form factor to minimize BOM footprint.
• DSP-Friendly Resources – Array multipliers and the cell architecture at the series level facilitate implementation of arithmetic functions without heavy busing resources.
• Commercial Temperature and Voltage Range – 3.0–3.6 V supply and 0 °C to 70 °C operating range match typical commercial embedded system requirements.
• RoHS Compliant – Conforms to RoHS requirements for lead-free assembly processes.
