AT6005A-4AI

The AT6005A-4AI is an SRAM-based Field Programmable Gate Array from Microchip Technology designed for reconfigurable, compute-intensive logic. The device uses a symmetrical array of small logic cells connected by a flexible busing network and is targeted at applications that require hardware acceleration, adaptive logic, and high I/O density.

With a logic fabric of 3,136 cells (approximately 15,000 usable gates) and 108 user I/Os in a 144-LQFP package, the AT6005A-4AI delivers system-ready performance for industrial-grade designs that operate from a 4.5 V to 5.5 V supply and across an operating temperature range of −40 °C to 85 °C.

Key Features

• Core architecture — Symmetrical array of identical cells with a high-speed local and express busing network for efficient medium- and long-distance routing and communication.
• Logic capacity — 3,136 logic cells (3,136 registers maximum) and approximately 15,000 usable gates for implementing compute-intensive functions and custom logic.
• I/O flexibility — 108 user I/Os with independently configurable I/O characteristics: TTL/CMOS input thresholds, open-collector/tristate outputs, programmable slew-rate control, and 16 mA drive (combinable to 64 mA).
• Performance — System speeds greater than 100 MHz with flip-flop toggle rates above 250 MHz; low input and output delays (example documented values: 1.2 ns/1.5 ns input delay and 3.0 ns/6.0 ns output delay).
• Configuration — Support for complete and partial in-system reconfiguration, enabling adaptive hardware and reconfiguration without loss of data or machine state.
• Power and efficiency — Typical operating current for the AT6005 device in its family is specified at 40–80 mA; series-level standby currents are documented as low as 500 μA / 200 μA in datasheet excerpts.
• Package and environmental — Surface-mount 144-LQFP (20 × 20) package with industrial-grade operating temperature from −40 °C to 85 °C and RoHS compliance.
• Toolchain support — Device series supported by Atmel/Microchip Integrated Development System for PC and workstation-based design entry.

Typical Applications

• Reconfigurable coprocessors — Use the AT6005A-4AI to offload and accelerate compute-intensive functions with in-field reconfiguration to adapt to changing workloads.
• Hardware acceleration — Implement cache-logic style accelerators and adaptive hardware to increase system throughput and reduce latency in targeted tasks.
• Industrial control and automation — Industrial-grade temperature range and 5 V-compatible I/O make this device suitable for control logic, motor control interfaces, and factory automation modules.
• Interface bridging and I/O expansion — High I/O count and programmable I/O standards enable protocol bridging, bus interfacing, and custom peripheral aggregation.
• High-speed logic prototyping — Fast system and flip-flop toggle rates support prototyping and verification of timing-sensitive digital logic.

Unique Advantages

• Balanced performance and density: 3,136 logic cells and ~15,000 usable gates provide a compact yet capable fabric for medium-complexity designs.
• Flexible I/O capability: Independently configurable I/Os with programmable thresholds and drive strengths simplify integration with mixed-voltage interfaces and custom peripherals.
• In-system adaptability: Complete and partial reconfiguration enables updates and algorithm changes in the field without losing machine state.
• Predictable timing: Documented system speeds >100 MHz and low input/output delays support timing-sensitive implementations.
• Industrial-ready packaging and thermal range: 144-LQFP surface-mount package and −40 °C to 85 °C operating temperature suit rugged embedded applications.
• Established toolchain support: Supported by Atmel/Microchip development tools for PC and workstation-based design entry and implementation.
