AT40K05LV-3DQI

The AT40K05LV-3DQI is an SRAM-based FPGA offered in a 208‑BFQFP surface‑mount package, designed for industrial temperature operation. It delivers a compact, reconfigurable fabric with 256 logic elements, approximately 2,048 bits of distributed on‑chip SRAM, and 128 I/O pins for system-level interfacing.

Targeted at applications requiring fast arithmetic and flexible memory, this device combines multi‑clock support and on‑chip FreeRAM capability to accelerate DSP, coprocessing and embedded control tasks while supporting 3.0–3.6 V supply systems.

Key Features

• Core Performance – Series-level architecture supports system speeds to 100 MHz and array multipliers above 50 MHz; each core cell includes internal tri‑state capability for flexible routing.
• Logic Capacity – 256 logic elements (cells) and approximately 10,000 usable gates provide compact programmable logic for mid‑scale designs.
• Embedded Memory (FreeRAM) – 2,048 bits of distributed 10 ns SRAM independent of logic cells; supports single/dual‑port and synchronous/asynchronous configurations for FIFOs and scratchpad memory.
• I/O and Drive – 128 I/O pins with programmable output drive; designed for flexible array access and pin locking required by multi‑signal systems.
• Clocking – Up to 8 global clocks with low‑skew distribution, programmable edge transitions and distributed clock shutdown for power management; includes dedicated PCI clock capability in series feature set.
• Reconfigurability – Cache Logic dynamic partial/full reconfigurability allows in‑system configuration updates without loss of data, enabling adaptive designs and rapid vector/coefficient changes.
• Package & Mounting – Surface mount 208‑BFQFP (supplier package: 208‑PQFP, 28×28 mm) for industry standard PCB assembly.
• Supply & Temperature – Operates from 3.0 V to 3.6 V and rated for industrial ambient temperatures from −40°C to 85°C.
• Environmental – RoHS compliant.

Typical Applications

• DSP and Coprocessing: Implement adaptive FIR filters, FFTs and arithmetic accelerators using on‑chip array multipliers and distributed SRAM for intermediate data storage.
• Multimedia & Video Processing: Use the reconfigurable fabric and fast memory access to handle compute‑intensive video compression, decompression and transform blocks.
• Embedded Control & Interfaces: Provide flexible I/O and programmable logic for glue logic, protocol bridging and custom control functions in industrial systems.

Unique Advantages

• Compact, Reconfigurable Fabric: 256 logic elements with Cache Logic reconfiguration supports iterative design updates and in‑field algorithm changes without hardware swaps.
• Fast On‑Chip Memory: Distributed 10 ns FreeRAM (2,048 bits) lets you implement single/dual‑port RAMs without consuming logic resources, simplifying FIFO and buffer designs.
• Multi‑Clock Flexibility: Eight global clocks and programmable edge control enable low‑skew timing architectures and selective clock shutdown to manage power.
• Industrial Temperature Range: −40°C to 85°C rating supports deployment in temperature‑sensitive industrial environments.
• Standard Surface‑Mount Package: 208‑BFQFP (28×28 mm PQFP equivalent) eases PCB design and assembly for existing manufacturing flows.
• Design Ecosystem Support (Series‑Level): Series documentation and tool integration described for industry tools and IP macro generators that streamline implementation of common functions like FIR, UART and PCI interfaces.
