AT40K40AL-1BQI

The AT40K40AL-1BQI is an SRAM-based FPGA from Microchip Technology’s AT40KAL family, delivering a mid-to-high gate-count programmable fabric in a 144-LQFP package. As a PCI-compliant, reconfigurable logic device with built-in distributed SRAM and Cache Logic reconfigurability, it addresses compute-intensive embedded and signal-processing designs that require flexible on-chip memory and multi-clock timing domains.

Designed for industrial applications, this device combines up to 50,000 gates, 2,304 logic elements, and 18,432 bits of distributed RAM with 114 I/O pins, enabling integration of coprocessor functions, DSP accelerators, and custom control logic within a compact surface-mount package.

Key Features

• Core Architecture  SRAM-based FPGA fabric with 2,304 logic elements (cells) supporting up to 50,000 usable gates for complex logic implementation.
• Embedded Memory (FreeRAM)  Approximately 18,432 bits of distributed 10 ns SRAM available as flexible single/dual-port, synchronous or asynchronous blocks for FIFOs, scratch pads, and data buffering without consuming separate external memory.
• Performance  System speeds to 100 MHz and array multipliers capable of >50 MHz; 10 ns SRAM and internal tri-state capability in each cell support high-speed arithmetic and DSP functions.
• I/O and Clocking  114 I/O pins with programmable output drive and support for multiple clock domains via 8 global clocks and 4 additional dedicated PCI clocks, enabling low-skew distribution and flexible timing control.
• Reconfigurability  Cache Logic dynamic full/partial re-configurability enables in-system updates and adaptive designs with unlimited reprogrammability through serial or parallel modes.
• Package & Mounting  Surface-mount 144-LQFP (20 × 20 mm) package suited for compact board layouts and manufacturing.
• Supply & Temperature  Supply voltage range 3 V to 3.6 V and industrial operating temperature range from −40 °C to 85 °C for deployment in industrial environments.
• Standards & Tool Support  PCI-compliant I/O behavior and compatibility with industry-standard design tools and synthesis flows (as supported by the AT40KAL family) for streamlined development and migration.
• Compliance  RoHS compliant for regulatory and environmental concerns.

Typical Applications

• DSP and Coprocessor Acceleration  Implement adaptive FIR filters, FFTs, convolvers and other arithmetic-intensive blocks using the device’s fast array multipliers and distributed RAM.
• Multimedia & Video Processing  Support for vector multipliers and on-chip RAM enables video compression/decompression, DCT, and related multimedia algorithms.
• Secure Communications & Encryption  Custom cryptographic engines and protocol offloads can be mapped to the FPGA fabric and RAM to accelerate secure data processing.
• Industrial Control & Automation  Use the device’s industrial temperature range, multiple clocks and abundant I/O for motor control, sensor interfacing and deterministic control logic.

Unique Advantages

• Flexible On-Chip Memory:  Distributed 10 ns SRAM (approximately 18,432 bits) can be instantiated without sacrificing logic cells, reducing reliance on external memory and lowering BOM cost.
• Dynamic Reconfiguration:  Cache Logic supports partial/full in-system reconfiguration, enabling adaptive updates and rapid algorithm changes without downtime.
• Multi-Clock Capability:  Eight global clocks plus dedicated PCI clocks provide robust clock distribution and low-skew timing control for complex, multi-domain designs.
• Compact Industrial Packaging:  144-LQFP surface-mount package (20 × 20 mm) with 114 I/Os offers a space-efficient integration point for industrial PCBs.
• High Throughput Arithmetic:  Built-in array multiplier architecture and fast SRAM enable high-speed DSP operations suitable for signal processing tasks.
• Proven Development Ecosystem:  Supported by the AT40KAL family’s design tool flow and automatic component generators for efficient synthesis and implementation.
