AT40K05-2RQC

The AT40K05-2RQC is an SRAM-based Field Programmable Gate Array (FPGA) from the AT40K family, supplied in a 100-pin BQFP package. It combines 256 logic elements with approximately 2,048 bits of distributed on-chip RAM and 78 user I/Os, targeted at applications that require reconfigurable logic, embedded memory and flexible I/O in a commercial-grade device.

As a member of the AT40K family, this device supports features such as 10 ns FreeRAM, multi-clock distribution and in-system reconfigurability, making it suitable for coprocessor tasks, DSP acceleration and adaptive logic implementations where fast, reprogrammable SRAM and deterministic logic resources are needed.

Key Features

• Core Architecture — SRAM-based FPGA architecture with 256 logic elements (cells) and 10 ns flexible SRAM timing for responsive, reprogrammable logic.
• Embedded Memory (FreeRAM) — Approximately 2,048 bits of distributed on-chip SRAM that can be configured as single-port or dual-port, synchronous or asynchronous memory blocks.
• I/O — 78 user I/Os with support for programmable output drive and mixed-voltage interfacing consistent with the AT40K family capabilities.
• Clocking — Family-level support includes multiple global clocks and low-skew distribution; part benefits from the AT40K series’ multi-clock architecture for synchronous designs.
• Performance — Family features include system speeds to 100 MHz and array multipliers exceeding 50 MHz, enabling higher-speed combinational and arithmetic functions.
• Package and Mounting — 100-BQFP surface-mount package (supplier package listed as 100-PQFP 14×20) for compact board integration.
• Supply and Temperature — 5 V class device with a specified supply range of 4.75 V to 5.25 V and commercial operating temperature range of 0 °C to 70 °C.
• Compliance — RoHS compliant.

Typical Applications

• DSP Coprocessor — Offload arithmetic-intensive functions such as FIR filters and FFTs using the device’s array multiplier capabilities and embedded RAM.
• Video and Multimedia Processing — Implement convolution, compression/decompression and other media accelerators leveraging on-chip RAM and reconfigurable logic.
• Encryption and Security — Deploy custom encryption cores and data-path logic that benefit from fast SRAM access and reprogrammability.
• Custom I/O and Interface Glue — Implement board-level protocol handling, bus interfacing or glue logic using the 78 general-purpose I/Os and programmable output drive.

Unique Advantages

• Flexible On-Chip Memory: Approximately 2,048 bits of distributed FreeRAM can be used for FIFOs, scratch pads or coefficient storage without consuming logic resources.
• Fast, Reconfigurable Logic: 10 ns SRAM and support for in-system partial/full reconfiguration enable adaptive designs and fast updates to computation kernels.
• Deterministic Performance: Family-level support for multi-clock distribution and high-speed array multipliers helps meet timing for DSP and coprocessor tasks.
• Compact Package: 100-pin BQFP surface-mount package provides a compact footprint for mid-density FPGA integration on commercial boards.
• Design Ecosystem: Part of the AT40K family with documented toolchain compatibility and automatic component generators for common IP functions (FIR, UART, PCI, FFT).
