AT40K05-2AQI

The AT40K05-2AQI is an SRAM-based Field Programmable Gate Array (FPGA) in the AT40K/AT40KLV family, provided in a 100-pin TQFP (14 × 14 mm) package. This industry-grade device delivers a compact, reprogrammable logic fabric with 256 logic elements, 2,048 bits of on-chip RAM and 78 I/O pins for mid-density embedded and DSP-oriented designs.

Designed for higher-performance system tasks, the AT40K05-2AQI supports system speeds to 100 MHz and includes features such as fast 10 ns distributed SRAM and dedicated clock resources, making it suitable for applications that require in-system reconfigurability and on-chip memory for tight integration of logic and data paths.

Key Features

• Core Performance — System speeds up to 100 MHz and array multipliers exceeding 50 MHz as specified for the AT40K family, enabling higher-throughput implementations.
• Logic Capacity — 256 logic elements (cells) suitable for mid-density logic functions and custom glue logic in embedded systems.
• Embedded Memory (FreeRAM) — Approximately 2,048 bits of distributed, flexible 10 ns SRAM for single- or dual-port configurations, supporting synchronous and asynchronous use without consuming separate logic resources.
• I/O and Interface — 78 I/O pins with 3V/5V capability in the AT40K family and programmable output drive options described for series devices.
• Clocking — Series-level support for 8 global clocks and additional dedicated PCI clock options for low-skew clock distribution and flexible timing control.
• Power and Supply — Supported supply range of 4.5 V to 5.5 V for the AT40K05 device.
• Package & Mounting — 100-TQFP (14 × 14 mm) surface-mount package for compact board-level integration.
• Industrial Temperature Range — Rated for operation from −40 °C to 85 °C for deployment in industrial environments.
• Reconfigurability & Tools — Part of the AT40K family which supports unlimited re-programmability via serial or parallel modes and integrates with industry-standard design tools as described for the series.
• Regulatory — RoHS compliant.

Typical Applications

• DSP Coprocessor — Implement FIR filters, FFTs and other arithmetic blocks using on-chip multipliers and distributed SRAM to offload compute-intensive tasks from a host processor.
• PCI and Interface Logic — Use the device in PCI-compliant or board-level interface functions that require dense I/O and reconfigurable logic for protocol bridging or custom peripheral control.
• Video and Multimedia Processing — Deploy array multipliers and embedded RAM to build video compression/decompression or streaming data-paths where partial reconfiguration and fast updates are beneficial.
• Embedded Control and Glue Logic — Replace multiple discrete components with a single reprogrammable device for sensor interfacing, motor control logic, or user-interface management.

Unique Advantages

• Balanced mid-density integration: 256 logic elements with 2,048 bits of embedded SRAM combine logic and memory for compact, efficient designs.
• Fast on-chip memory: 10 ns distributed SRAM enables tight coupling of data storage and logic operations for lower-latency designs.
• Flexible clocking: Multiple global clocks and programmable clock controls provide low-skew distribution and timing flexibility for synchronous designs.
• Industrial robustness: Operation from −40 °C to 85 °C and RoHS compliance support deployment in industrial applications.
• 5V supply compatibility: Supported supply range of 4.5 V to 5.5 V fits legacy and mixed-voltage systems where 5V operation is required.
• Reconfigurable in-system: Series-level capability for unlimited reprogramming and in-system partial/whole reconfiguration enables adaptive designs and field updates.
