AT40K20-2AQC

The AT40K20-2AQC from Microchip Technology is an SRAM-based field programmable gate array (FPGA) in a 100‑TQFP (14×14) package. It provides 1,024 logic elements, approximately 8,192 bits of embedded memory, and 78 user I/Os for mid-density, reconfigurable logic implementations.

Designed for applications that require on-board reconfigurability and DSP-style processing, this device combines fast distributed SRAM, array multiplier capability, and support for dynamic reconfiguration to accelerate tasks such as filters, transforms, and other computation-intensive functions.

Key Features

• Core Performance – Series-level system speeds to 100 MHz and array multipliers operating above 50 MHz enable high-throughput logic and arithmetic operations.
• Logic Capacity – 1,024 logic elements (cells) and approximately 30,000 gates provide a mid-range fabric suitable for coprocessor and accelerator roles.
• Embedded Memory (FreeRAM) – Approximately 8,192 bits of distributed 10 ns SRAM that can be configured as single- or dual-port, synchronous or asynchronous memory for FIFOs, scratch pads, and coefficient storage without consuming separate logic resources.
• I/O and Packaging – 78 I/O pins in a 100‑TQFP (14×14) surface-mount package for compact board integration and signal routing.
• Reconfigurability – Cache Logic dynamic partial/full in-system reconfigurability and unlimited re-programmability via serial or parallel modes enable adaptive designs and field updates.
• Clocking and Control – Series-level support for multiple global clocks, including fast, low-skew distribution and programmable edge behavior to manage synchronous domains and low-power shutdown of distributed clocks.
• Electrical and Environmental – 5 V supply recommended (operating range 4.75 V to 5.25 V) and commercial operating range of 0 °C to 70 °C. RoHS compliant.
• Design Ecosystem – Series documentation highlights support for industry-standard synthesis and CAD tool integration to streamline development and migration within the family.

Typical Applications

• DSP Coprocessors – Implement FIR filters, FFTs, convolvers and other arithmetic-intensive blocks to offload host processors and accelerate signal processing pipelines.
• Video and Multimedia Processing – Useful for video compression/decompression and transform operations where on-chip multipliers and fast embedded SRAM improve throughput.
• Adaptive and Reconfigurable Systems – In-system partial or full reconfiguration enables fast design updates and adaptive coefficient replacement for evolving algorithms.
• Encryption and Data Processing – Implement custom encryption engines, streaming transforms and protocol accelerators using the device’s logic and memory resources.

Unique Advantages

• Balanced Logic and Memory – 1,024 logic elements paired with ~8 Kbits of embedded SRAM supports medium-complexity designs without external memory.
• High-Speed Arithmetic – Array multiplier capability and fast SRAM (10 ns) enable high-speed arithmetic and DSP functions on-chip.
• In-System Reconfiguration – Cache Logic reconfigurability allows partial or full updates without loss of data, speeding iterative development and field upgrades.
• Compact, Surface-Mount Package – 100‑TQFP (14×14) package supports dense PCB layouts while providing a generous set of I/Os for peripheral interfacing.
• Commercial Temperature and 5 V Operation – Designed for standard commercial environments with a 4.75–5.25 V supply range and 0 °C to 70 °C operating range.
• RoHS Compliant – Conforms to RoHS requirements for environmentally conscious designs.
