AT40K20LV-3BQI

The AT40K20LV-3BQI is an industrial-grade, SRAM-based field programmable gate array (FPGA) in a 144-LQFP (20×20) surface-mount package. As part of the AT40K/AT40KLV series, it combines on-chip distributed SRAM and reconfigurable logic to accelerate computation-intensive functions in industrial and embedded systems.

Targeted use cases include DSP acceleration, custom I/O interfacing, and control logic for industrial equipment where a balance of logic density, embedded memory, and 3.3 V operation is required. The part offers series-level capabilities such as fast on-chip RAM timing and dynamic reconfiguration options to support adaptive designs.

Key Features

• Core Logic  1,024 logic elements (approximately 30,000 gates) for implementing medium-density logic and custom datapaths.
• Embedded Memory (FreeRAM)  8,192 bits of distributed on-chip SRAM; the AT40K/AT40KLV family provides flexible single/dual-port SRAM with 10 ns timing for FIFOs, scratch pads, and other on-chip storage.
• I/O and Voltage  114 user I/Os with supply voltage range 3.0 V to 3.6 V suitable for 3.3 V system designs.
• Clocking  Series-level support for multiple global clocks (the AT40K/AT40KLV family includes an 8-global-clock architecture) to simplify synchronous design and low-skew distribution.
• Reconfigurability  Cache Logic capability in the AT40K/AT40KLV family enables dynamic full or partial in-system reconfiguration and unlimited re-programmability via serial or parallel modes.
• Performance  The AT40K/AT40KLV series provides high system speeds (series-level guidance up to 100 MHz) and fast array multipliers (series-level performance >50 MHz) for arithmetic-intensive tasks.
• Package & Mounting  144-LQFP (20×20) plastic quad flat pack, surface-mount package for compact PCB layouts.
• Industrial Temperature Range  Rated for operation from -40 °C to 85 °C, suitable for industrial environments.
• Compliance  RoHS compliant.

Typical Applications

• DSP Acceleration  Implement FIR filters, FFTs and array multipliers using on-chip logic and FreeRAM for signal processing tasks.
• Video and Multimedia Processing  Offload compute-intensive transforms and convolution functions to the FPGA’s reconfigurable datapath and embedded RAM.
• Industrial Control  Custom control logic, sensor interfacing and motor-control peripherals benefit from the device’s 1,024 logic elements and extended temperature range.
• Custom I/O and Glue Logic  Leverage 114 I/Os and programmable drive capability (series-level feature) to bridge legacy and modern interfaces in compact designs.

Unique Advantages

• Compact reconfigurable platform: Integrates 1,024 logic elements and 8,192 bits of distributed SRAM to reduce external component count.
• 3.3 V system compatibility: Operates from 3.0 V to 3.6 V to fit standard 3.3 V embedded and industrial systems.
• In-system reprogrammability: Series-level Cache Logic and serial/parallel programming options enable field updates and adaptive designs.
• Industrial temperature rating: -40 °C to 85 °C operation supports deployment in demanding environments.
• Surface-mount LQFP package: 144-LQFP (20×20) provides a balance of pin count and PCB footprint for mid-density designs.
• RoHS compliant: Meets environmental compliance requirements for modern manufacturing.
