AT6005-4AC

The AT6005-4AC is an SRAM-based Field Programmable Gate Array from Microchip Technology's AT6000(LV) family, offering a balanced combination of logic density and I/O capability in a 100-TQFP (14×14) surface-mount package. The device implements a symmetrical grid of logic cells with surrounding programmable I/O, making it well suited for reconfigurable coprocessors and compute-intensive logic.

Designed for high-speed operation, the AT6005-4AC supports system speeds greater than 100 MHz and flip-flop toggle rates above 250 MHz, while providing independently configurable I/O and in-system reconfiguration for adaptive hardware implementations.

Key Features

• Core Architecture Symmetrical array of 3,136 logic cells (registers) implementing approximately 15,000 usable gates, enabling dense logic integration for custom hardware functions.
• Performance Supports system speeds > 100 MHz and flip-flop toggle rates > 250 MHz; input delays around 1.2 ns/1.5 ns and output delays around 3.0 ns/6.0 ns for predictable timing behavior.
• Programmable I/O 80 user I/O pins with independently configurable thresholds (TTL/CMOS), open-collector/tristate outputs, programmable slew-rate control and I/O drive of 16 mA (combinable up to 64 mA) for flexible interface design.
• Reconfiguration Complete and partial in-system reconfiguration capability without loss of data or machine state, enabling field updates and adaptive hardware acceleration.
• Power and Low-Power Modes Typical operating current for the AT6005 device is listed at 40–80 mA, with very low standby currents reported (on the series), supporting energy-conscious designs at a 5.0 V supply (VCC = 4.75 V to 5.25 V).
• Clocking and Timing Independently controlled column clocks and resets with clock skew less than 1 ns across the chip, plus programmable clock options to manage timing domains efficiently.
• Package & Environmental 100-TQFP (14×14) surface-mount package, commercial-grade operation from 0 °C to 70 °C, and RoHS compliant.

Typical Applications

• Reconfigurable Coprocessors: Implement hardware acceleration for compute-intensive tasks, leveraging the device’s dense cell array and high toggle rates.
• Custom Logic and Control: Replace multiple discrete logic components with a single programmable device for control logic, protocol handling, and glue logic in commercial embedded systems.
• Interface Bridging and I/O Expansion: Use the AT6005-4AC’s flexible and configurable I/O to implement bus bridges, protocol converters, or offload interface tasks from a host processor.
• Prototyping and Adaptive Hardware: Take advantage of in-system partial reconfiguration to iterate designs or adapt functionality in the field without full system downtime.

Unique Advantages

• Balanced Logic Density: 3,136 logic cells and ~15,000 usable gates provide a strong mix of capacity and granularity for complex custom functions without excessive device overhead.
• High-Speed Operation: System speeds > 100 MHz and flip-flop toggle rates > 250 MHz support demanding timing requirements for performance-critical designs.
• Flexible, Driven I/O: Independently configurable I/O with programmable thresholds, slew-rate control and combinable drive strength helps match signaling requirements and reduce external components.
• Field Reconfigurability: Complete and partial in-system reconfiguration preserves machine state and enables upgrades or feature changes in deployed systems.
• Predictable Timing: Low clock skew across the chip and defined input/output delays simplify timing closure and deterministic behavior in synchronous designs.
• Commercial Packaging and Compliance: Available in a 100-TQFP (14×14) surface-mount package with RoHS compliance for commercial electronics manufacturing.
