AT40K20-2EQC

The AT40K20-2EQC is an SRAM-based FPGA in the AT40K family, offering mid-range programmable logic density with distributed on-chip RAM and high-speed arithmetic capability. It combines 1,024 logic elements, 8,192 bits of embedded SRAM, and 193 I/O pins in a 240‑BFQFP surface-mount package for commercial embedded designs.

Designed for performance-oriented applications, the device operates from a 4.75 V to 5.25 V supply and supports an operating temperature range of 0 °C to 70 °C. Family-level features include high system speeds, multi-clock support and in-system reconfigurability that help accelerate DSP, multimedia and custom logic designs.

Key Features

• Core Logic — 1,024 logic elements (approximately 30,000 usable gates) with internal tri-state capability in each cell to support dense, flexible logic implementations.
• Embedded Memory (FreeRAM) — 8,192 bits of distributed 10 ns SRAM available as flexible single- or dual-port, synchronous or asynchronous memory for FIFOs, buffers and scratchpad storage without consuming separate logic resources.
• I/O — 193 I/O pins in the 240‑BFQFP package; family supports PCI-compliant I/Os and 3 V/5 V capability with programmable output drive and pin-locking features.
• Clocking — Up to 8 global clocks with low-skew distribution and programmable edge transitions, plus additional dedicated PCI clocks for multi-domain timing control.
• Reconfigurability — Cache Logic dynamic full/partial in-system reconfigurability with unlimited reprogramming via serial or parallel modes, enabling adaptive designs and rapid updates.
• Performance — System speeds up to 100 MHz, array multipliers exceeding 50 MHz and fast 10 ns SRAM for high-throughput arithmetic and signal processing tasks.
• Package, Supply & Compliance — Surface-mount 240‑BFQFP (240‑PQFP footprint 32×32), supply voltage 4.75–5.25 V, operating range 0 °C to 70 °C, and RoHS compliant.

Typical Applications

• DSP Coprocessor — Implement FIR filters, FFTs, convolvers and other compute-intensive arithmetic functions to offload processors and accelerate signal processing workloads.
• Video and Multimedia Processing — Use array multipliers and embedded SRAM for real-time compression, decompression and transform operations in video/audio pipelines.
• Encryption and Security — Implement custom bit-level and arithmetic operations required for encryption and secure data processing.
• Hardware Prototyping & Rapid Iteration — In-system partial/full reconfigurability and unlimited reprogramming enable fast design iterations and algorithm updates without board-level changes.

Unique Advantages

• Flexible on-chip RAM: Distributed 10 ns FreeRAM provides dedicated memory resources that can be instantiated independently of logic elements, reducing external RAM needs and simplifying designs.
• High-throughput arithmetic: Direct cell-to-cell connections and optimized core architecture enable fast array and vector multipliers for compute-heavy functions.
• Dynamic reconfiguration: Cache Logic allows full or partial in-system reconfiguration so designs can adapt or be updated without complete device replacement.
• PCI-capable I/O and voltage flexibility: Family-level PCI-compliant I/O support and 3 V/5 V capability provide interface flexibility for mixed-voltage systems while the specific device uses a 5 V supply range.
• Toolchain and IP support: Industry-standard design tool integration and available IP cores (FIR filters, UARTs, PCI, FFT, etc.) speed development and reduce time-to-market.
• Package and production migration: Available in industry-standard packages with an easy migration path to Atmel gate arrays for higher-volume production.
