AT40K10-2DQC

The AT40K10-2DQC is an SRAM-based Field Programmable Gate Array (FPGA) from Microchip Technology's AT40K family, designed for high-performance, reconfigurable logic in commercial applications. It provides roughly 20,000 usable gates implemented across 576 logic elements, with 4,608 bits of distributed on-chip RAM and 161 user I/O pins in a 208‑BFQFP package.

Targeted at designers needing flexible, medium-density programmable logic, the device supports high-speed datapath and DSP functions, in-system reconfiguration, and 5 V supply operation (4.75 V to 5.25 V), making it suitable for a range of embedded and system-level acceleration roles.

Key Features

• Core Logic — 576 logic elements (cells) delivering approximately 20,000 usable gates for mid-range programmable designs.
• Embedded Memory (FreeRAM™) — 4,608 bits of distributed SRAM with 10 ns access; supports flexible single- or dual-port, synchronous or asynchronous configurations for FIFOs, scratch pads and other memory functions.
• I/O — 161 user I/Os in the 208‑pin BFQFP package; family-level support for PCI‑compliant I/Os and programmable output drive (as described for AT40K series).
• Clocking — Family-level architecture provides up to 8 global clocks and additional dedicated PCI clocks, enabling low-skew distribution and clock control features such as programmable edge transitions and distributed clock shutdown.
• Performance — Family-level system speeds to 100 MHz and array multipliers running above 50 MHz; 10 ns SRAM and internal tri‑state capability in each cell help support high-throughput datapaths.
• Reconfiguration and Tools — Series-level Cache Logic dynamic partial/full reconfigurability and unlimited reprogramming via serial or parallel modes for adaptive designs and rapid updates.
• Package & Mounting — Surface-mount 208‑BFQFP (208‑PQFP, 28×28) package suitable for standard PCB assembly processes; RoHS compliant.
• Electrical & Environmental — 5 V supply range (4.75 V to 5.25 V) and commercial operating temperature range of 0 °C to 70 °C.

Typical Applications

• DSP and Coprocessor Acceleration — Implement FIR filters, FFTs, and other compute-intensive blocks using the device's fast array multipliers and distributed SRAM to offload processors and improve throughput.
• Multimedia Processing — Use distributed memory and arithmetic resources for video compression, decompression and convolution functions in embedded multimedia systems.
• High‑speed Interfaces — Mid-density I/O capability and family-level PCI-compliant I/O support make the device suitable for bridging and protocol-handling tasks in system designs.
• Adaptive Logic and In‑System Updates — Cache Logic reconfigurability enables field updates and fast design iteration for systems that require runtime adaptability.

Unique Advantages

• Balanced Mid-range Density: ~20K usable gates and 576 logic elements provide significant logic capacity while keeping package and power requirements moderate for commercial designs.
• Fast On-chip Memory: 4,608 bits of distributed 10 ns SRAM (FreeRAM™) enable local buffering and dual-port memory configurations without consuming additional logic resources.
• Flexible Clocking: Multiple global clocks and programmable clock controls support low-skew, power‑aware clock domain management for complex timing requirements.
• Reconfigurable In-system: Series-level dynamic partial/full reconfigurability and unlimited reprogramming modes allow rapid updates and adaptive algorithms in deployed systems.
• 5 V Compatibility: Designed for 5 V supply operation (4.75 V to 5.25 V), simplifying integration into legacy 5 V platforms where required.
• Commercial-grade Reliability: RoHS-compliant construction and a defined operating range of 0 °C to 70 °C provide predictable behavior for commercial embedded applications.
