AT40K05LV-3DQC

The AT40K05LV-3DQC is an SRAM-based Field Programmable Gate Array (FPGA) in a 208-BFQFP package, designed for commercial applications that require flexible on-chip logic and embedded memory. It implements a compact logic array with 256 logic elements, approximately 10,000 usable gates and 2,048 bits of distributed on-chip SRAM (FreeRAM).

Architected for high-performance, reconfigurable designs, the device supports a 3.0 V to 3.6 V supply range (3.3 V nominal for the AT40KLV series), 128 I/O pins, and an operating temperature range of 0 °C to 70 °C. The combination of fast SRAM, multiple global clocks and programmable I/O makes it suitable for DSP coprocessor roles and other compute-intensive embedded functions.

Key Features

• Core Performance: System speeds up to 100 MHz and array multipliers specified above 50 MHz enable high-speed logic and arithmetic operations.
• Logic Capacity: 256 logic elements (cells) providing around 10,000 usable gates and 256 on-chip registers for compact logic implementations.
• Embedded Memory (FreeRAM): Approximately 2,048 bits of distributed 10 ns SRAM usable as flexible single‑port or dual‑port memory (synchronous/asynchronous).
• I/O and Interface Flexibility: 128 I/O pins with PCI-compliant I/O features in the family, programmable output drive and 3 V/5 V signaling capability described for the series.
• Clocking: Eight global clocks with low-skew distribution, programmable edge transitions and options for distributed clock shutdown for power management.
• Dynamic Reconfiguration: Cache Logic dynamic partial/full re-configurability (series feature) enables unlimited in-system reprogramming via serial or parallel modes.
• Package & Mounting: Surface-mount 208-BFQFP package (supplier package: 208-PQFP, 28 × 28 mm) for compact PCB integration.
• Environmental & Power Specs: Commercial grade operation from 0 °C to 70 °C and supply voltage range of 3.0 V to 3.6 V.

Typical Applications

• DSP Coprocessor: Implement FIR filters, FFTs and other arithmetic accelerators using the device’s array multipliers and distributed RAM to offload processor-intensive tasks.
• Video and Multimedia Processing: Use embedded RAM and reconfigurable cache logic to handle coefficient storage and rapid algorithm updates for video compression/decompression and related functions.
• Encryption and Security Accelerators: Leverage on-chip logic and fast SRAM to implement cryptographic primitives and high-throughput data-paths.
• Prototyping and System Integration: Fast reprogramming and pin-compatible package options in the series aid in design iteration and board-level integration for commercial embedded systems.

Unique Advantages

• Flexible on-chip memory: Distributed 10 ns FreeRAM (≈2,048 bits) allows memory functions without consuming logic resources, simplifying FIFOs, scratch pads and buffers.
• Reconfigurability in-system: Cache Logic enables partial or full dynamic reconfiguration for adaptive designs and rapid updates without losing stored data.
• High-speed arithmetic support: Array multipliers and direct cell interconnections enable fast vector and array multiplication for DSP workloads.
• Multiple global clocks: Eight global clocks with programmable behavior provide low-skew distribution and flexible clock management for timing-critical systems.
• Compact, surface-mount packaging: 208-BFQFP (28 × 28 PQFP) allows dense PCB layouts while exposing 128 I/O for broad interface capability.
