AT40K20-2BQJ

The AT40K20-2BQJ is an SRAM-based field programmable gate array (FPGA) offered in a 144-LQFP (20×20) surface-mount package. The device provides 1,024 logic elements, approximately 8,192 bits of embedded RAM, and 114 programmable I/O lines, making it suitable for mid-density digital designs that require on-chip memory and flexible I/O. With industrial grade temperature ratings and a 4.5 V to 5.5 V supply range, this device targets industrial and embedded applications that need reconfigurable logic with reliable environmental tolerance.

Key Features

• Core Performance – Series-level architecture supports system speeds up to 100 MHz and array multipliers rated over 50 MHz, enabling responsive logic processing for a range of control and signal tasks.
• Logic Capacity – 1,024 logic elements (cells) and approximately 30,000 equivalent gates provide mid-range integration for combinational and sequential designs.
• Embedded Memory (FreeRAM) – Approximately 8,192 bits of distributed 10 ns SRAM for flexible single/dual-port, synchronous/asynchronous memory functions without consuming separate logic resources.
• I/O and Drive – 114 programmable I/O pins with 3 V/5 V capability and programmable output drive (series-level feature), offering adaptable interfacing for mixed-voltage systems.
• Clocking and Reconfiguration – Series features include up to 8 global clocks with low-skew distribution and Cache Logic capability for dynamic partial or full in-system reconfigurability.
• Package and Mounting – 144-LQFP (20×20) surface-mount package for compact board-level integration and standard PCB assembly processes.
• Power and Temperature – Supply voltage range 4.5 V to 5.5 V and operating temperature from −40 °C to 85 °C, supporting industrial-environment deployments.
• Compliance – RoHS compliant.

Typical Applications

• Industrial Control: Implement state machines, interface logic, and control functions where reprogrammability and an industrial temperature range are required.
• Embedded System Coprocessing: Use on-chip logic and RAM to offload computation-heavy tasks or implement custom accelerators within a mid-density footprint.
• Interface Bridging and I/O Expansion: Leverage 114 programmable I/Os to adapt board-level peripherals, protocol translation, and mixed-voltage interfacing.
• Signal Processing Primitives: Utilize the device’s distributed RAM and array multiplier capabilities for FIR filters, FFTs, or other arithmetic blocks within a reconfigurable fabric.

Unique Advantages

• Flexible On-chip Memory: Distributed 10 ns SRAM enables single- or dual-port memory functions without dedicating additional logic, simplifying FIFO and scratch-pad designs.
• Reconfigurable Operation: Cache Logic and in-system reprogramming options (series capability) allow partial or full reconfiguration for adaptive designs and field updates.
• Mid-density Integration: 1,024 logic elements and ~30,000 gates balance capacity and cost for designs that exceed small CPLD capability but do not require high-end FPGAs.
• Industrial Readiness: −40 °C to 85 °C operating range and RoHS compliance support deployment in industrial embedded environments.
• Standard Package Footprint: 144-LQFP surface-mount package simplifies PCB routing and assembly while providing ample I/O for peripheral connectivity.
• PCI-Ready I/O Capability (Series Feature): The family’s PCI-compliant I/O architecture and programmable drive characteristics facilitate integration with common bus and peripheral standards when required.
