AT40K05LV-3BQI

The AT40K05LV-3BQI is a 3.3 V, SRAM-based field programmable gate array (FPGA) supplied in a 144-LQFP (20 × 20) package. It implements 256 logic elements and approximately 2,048 bits of distributed on-chip RAM, delivering a compact, reprogrammable fabric for performance-sensitive embedded designs.

Designed for reconfigurable acceleration and system I/O tasks, this device supports high-speed internal operation (system speeds to 100 MHz) and features distributed 10 ns SRAM and on-chip multiplier-friendly routing—making it suitable for DSP-oriented coprocessor functions, PCI-compliant I/O designs, and other adaptive logic applications.

Key Features

• Core and Performance – System speeds to 100 MHz with array multipliers capable of >50 MHz performance for computation-heavy tasks.
• Embedded SRAM (FreeRAM) – Approximately 2,048 bits of flexible, single/dual-port synchronous/asynchronous 10 ns SRAM for FIFOs, scratch pads, and data buffering independent of logic elements.
• Logic Capacity – 256 logic elements (cells) delivering roughly 10,000 usable gates for mid-density FPGA implementations.
• I/O and Package – 114 I/Os in a 144-LQFP (20×20) surface-mount package; programmable drive and pin-locking options enable flexible board-level integration.
• Clocking and Timing – Up to 8 global clocks with low-skew distribution and programmable edge control to simplify synchronous design and power management.
• Reconfiguration – Cache Logic dynamic full/partial re-configurability enables in-system updates and adaptive designs without losing stored data.
• Power and Environmental – 3 V to 3.6 V supply range with industrial operating temperature from −40 °C to 85 °C.
• Toolchain Interoperability – Supported by industry-standard design and synthesis tools for timing-driven placement, routing, and IP integration.

Typical Applications

• DSP Acceleration: Implement FIR filters, FFTs, vector multipliers and other arithmetic kernels using on-chip multipliers and distributed SRAM for high-throughput processing.
• Video and Multimedia Processing: Use reconfigurable logic and embedded memory to implement compression/decompression, transforms, and other real-time media functions.
• Encryption and Security: Deploy flexible, reprogrammable logic to accelerate encryption algorithms and update implementations in-system.
• PCI-compliant I/O Interfaces: Integrate parallel and high-count I/O functions with programmable drive and pin allocation for interface bridging and protocol handling.

Unique Advantages

• Flexible embedded RAM: Distributed 10 ns FreeRAM lets you implement multiple small RAMs without sacrificing logic resources.
• Dynamic reconfiguration: Cache Logic enables partial or full in-system reconfiguration, supporting adaptive updates and fast algorithm changes.
• Balanced mid-density capability: 256 logic elements and roughly 10k usable gates provide a compact footprint for mid-range FPGA tasks while keeping board-level complexity low.
• High-performance datapaths: 8-sided core cell connectivity and fast array multipliers support efficient implementation of arithmetic-intensive functions.
• Industrial robustness: Rated for −40 °C to 85 °C operation and surface-mount 144-LQFP packaging for reliable deployment in industrial environments.
• 3.3 V operation: Native 3.3 V supply compatibility simplifies integration into low-voltage system designs.
