Overview of AT40K40-2FQI – Field Programmable Gate Array (FPGA), 2,304 logic elements, ~18,432-bit FreeRAM, 256 I/Os, 304-BFQFP
The AT40K40-2FQI is a SRAM-based Field Programmable Gate Array optimized for high-performance, reconfigurable logic and embedded memory functions. It implements 2,304 logic elements (cells) and approximately 18,432 bits of distributed on-chip RAM (FreeRAM), providing a compact platform for DSP acceleration, coprocessing and complex glue-logic tasks.
Designed for 5 V systems (nominal supply range 4.5 V to 5.5 V) and industrial operating temperatures (−40°C to 85°C), this surface-mount device in a 304-pin BFQFP package offers 256 I/Os, eight global clocks and Cache Logic reconfigurability for in-system updates and adaptive designs.
Key Features
- Core & Architecture SRAM-based FPGA architecture with internal tri-state capability in each cell and support for dynamic partial or full re-configurability via Cache Logic.
- Logic Capacity 2,304 logic elements (cells) and a usable gate count around 50,000 gates, enabling medium-density logic integration.
- Embedded Memory (FreeRAM) Approximately 18,432 bits of distributed 10 ns SRAM available as flexible single- or dual-port memory, usable synchronously or asynchronously without consuming logic resources.
- I/O and Interface Up to 256 user I/Os with 3 V/5 V capability and programmable output drive; pin-compatible package options are supported by the series.
- Clocking Eight global clocks with low-skew distribution, programmable edge transitions and distributed clock shutdown for power management, plus additional dedicated PCI clocks available in the family.
- Performance Architectural capabilities support system speeds up to 100 MHz, array multipliers exceeding 50 MHz and 10 ns SRAM access for fast datapath operations.
- Package & Mounting Surface-mount 304-BFQFP package (supplier device package listed as 304-PQFP 40×40) suitable for board-level assembly in industrial designs.
- Environmental & Supply RoHS compliant; nominal supply 4.5 V–5.5 V and industrial temperature rating −40°C to 85°C.
Typical Applications
- DSP Coprocessing Use as a coprocessor for computation-intensive functions such as FIR filters and FFTs to offload processors and accelerate signal processing.
- Video and Multimedia Processing Implements array multipliers and configurable memory to support video compression/decompression and related codec functions.
- Embedded System Glue Logic Integrate custom interfaces, protocol bridging and control logic where moderate gate density and abundant I/O are required.
- Adaptive / In-System Reconfigurable Designs Cache Logic enables partial or full in-system reconfiguration for adaptive algorithms and fast vector multiplier updates.
Unique Advantages
- Flexible On-Chip Memory: Approximately 18,432 bits of distributed 10 ns FreeRAM provide fast, configurable storage without consuming logic resources, simplifying FIFO and scratch-pad implementations.
- Synchronous and Asynchronous RAM Modes: FreeRAM supports single- and dual-port operation in either synchronous or asynchronous modes, giving design flexibility for varied dataflow requirements.
- Reconfigurability with Cache Logic: In-system partial/full re-programmability enables design updates and adaptive behavior without removing the device from the board.
- Rich Clocking Resources: Eight global clocks with programmable edges and low skew support complex timing domains and reliable synchronous designs.
- Industrial Temperature and RoHS Compliance: Rated for −40°C to 85°C operation and RoHS compliant for deployment in industrial environments.
- High I/O Count in Compact Package: 256 I/Os in a 304-pin BFQFP package provide dense interfacing options for multi-channel or multi-protocol systems.
