AT40K20AL-1AQC

The AT40K20AL-1AQC is an SRAM-based FPGA from the AT40KAL family designed for high-performance, reconfigurable logic tasks. It integrates approximately 1,024 logic elements, 8,192 bits of distributed on-chip RAM, and 78 general-purpose I/Os in a 100‑pin TQFP (14×14 mm) surface-mount package.

Targets include high-speed, processor-assisted designs and DSP-oriented applications where flexible memory, in-system reconfiguration and native arithmetic support improve system throughput and design agility. The device operates from a 3.0 V to 3.6 V supply and is specified for commercial temperature environments (0 °C to 70 °C).

Key Features

• Core Performance – Series-level architecture supports system speeds up to 100 MHz and array multipliers exceeding 50 MHz; includes internal tri-state capability per cell for flexible logic implementation.
• Logic Resources – Approximately 1,024 logic elements (cells) and an estimated 30,000 usable gates provide a balance of density and deterministic logic for mid-range FPGA tasks.
• Embedded Memory (FreeRAM) – 8,192 bits of distributed, flexible SRAM with 10 ns access characteristics; supports single/dual port and synchronous/asynchronous configurations as supported by the AT40KAL series.
• I/O and Drive – 78 general-purpose I/Os with series-programmable output drive options at the family level; supports mixed-signal interfacing within the specified voltage range and 5 V I/O tolerance per series documentation.
• Clocking – Series architecture includes up to eight global clock networks for low-skew distribution and flexible clock control, including programmable edge transitions and distributed clock shutdown features.
• Reconfiguration (Cache Logic) – Series-level dynamic full/partial re-configurability for in-system updates via serial or parallel modes, enabling adaptive designs and quick design iteration.
• Package & Mounting – 100‑TQFP (14×14 mm) surface-mount package optimized for compact PCB layouts and standard SMT assembly processes.
• Electrical & Environmental – Supply voltage 3.0 V to 3.6 V, commercial operating temperature range 0 °C to 70 °C, and RoHS compliant.

Typical Applications

• DSP Coprocessors – Implement high-throughput arithmetic kernels such as FIR filters and FFTs alongside a host processor to offload compute-intensive tasks.
• Video and Multimedia Processing – Support functions like video compression/decompression and convolution where embedded RAM and fast array multipliers accelerate data paths.
• Encryption and Signal Processing – Deploy custom encryption engines and real-time signal transforms using the device’s logic fabric and distributed SRAM.
• Adaptive/Updatable Systems – Use Cache Logic reconfiguration for field-updatable coefficients and algorithms without full device replacement.

Unique Advantages

• Flexible On-Chip Memory: Distributed 10 ns SRAM (8,192 bits) lets you implement FIFOs, scratch pads or coefficient storage without consuming additional logic resources.
• Reconfigurability In-System: Series-level Cache Logic enables partial or full reconfiguration via serial/parallel modes for iterative development and adaptive designs.
• Balanced Logic Density: Approximately 1,024 logic elements and ~30,000 gates provide sufficient capacity for mid-range FPGA implementations while keeping board area modest.
• Practical I/O Count: 78 general-purpose I/Os in a 100‑TQFP package simplify routing for compact designs while offering programmable drive capability.
• DSP-Friendly Architecture: Dedicated array multiplier performance and cell interconnect topology support efficient implementation of arithmetic-intensive functions.
• Standard SMT Package: 100‑TQFP surface-mount package offers compatibility with common PCB assembly processes and compact system footprints.
