AT6002A-4AC

The AT6002A-4AC is an AT6000(LV) series SRAM-based FPGA from Microchip Technology, designed for reconfigurable coprocessors and compute-intensive logic. Its architecture uses a symmetrical array of small logic cells with a flexible busing network to support adaptive hardware and hardware acceleration.

This device provides 1,024 logic elements (cells), approximately 6,000 usable gates, up to 95 user I/Os in a 144-LQFP (20×20) surface-mount package, and operates from a 4.75 V to 5.25 V supply within a commercial temperature range of 0 °C to 70 °C. The part is RoHS compliant.

Key Features

• Core architecture – Symmetrical array of identical cells connected by a high-speed busing network, enabling efficient routing and logic placement across the chip.
• Performance – Series specifications include system speeds greater than 100 MHz and flip-flop toggle rates above 250 MHz; measured input and output delays are listed in the series documentation.
• Logic resources – Approximately 6,000 usable gates and 1,024 logic elements (cells) with up to 1,024 registers for implementing compute-intensive functions.
• I/O flexibility – Up to 95 user I/Os that are independently configurable with TTL/CMOS input thresholds, open-collector/tristate outputs, programmable slew-rate control and 16 mA drive per pin (combinable to higher drive).
• Configuration and design – Supports complete or partial in-system reconfiguration with no loss of data or machine state; design flow supported by a PC- and workstation-based Integrated Development System and reusable custom hard macro generators.
• Power – Designed for very low-power operation with standby currents reported in the series documentation and typical operating current ranges provided for AT6000 devices.
• Package and environmental – 144-LQFP (20×20) surface-mount package, RoHS compliant, commercial grade, and rated for 0 °C to 70 °C operating temperature.

Typical Applications

• Reconfigurable coprocessors – Implement hardware acceleration and offload compute-intensive tasks using the device’s arrayed logic and register resources.
• Adaptive hardware – Use cache-logic design methods and in-system reconfiguration to implement adaptive or evolving hardware functions without losing machine state.
• High-speed control and signal processing – Leverage the device’s >100 MHz system speeds and configurable I/O for timing-sensitive control and processing blocks.
• Embedded system integration – Fit moderate gate-count FPGA capability into a 144-LQFP package for space-constrained board designs with extensive I/O needs.

Unique Advantages

• Independent column clocking – Independently controlled column clocks and resets with clock skew less than 1 ns across the chip enable precise timing and partitioned clock domains.
• Compact, dense logic – Approximately 1,024 logic elements and ~6,000 usable gates in a single 144-LQFP package simplify integration of acceleration logic into existing systems.
• Flexible interface options – Independently configurable I/O with TTL/CMOS thresholds, programmable slew-rate and significant drive capability support diverse external interfaces.
• In-system reconfiguration – Complete and partial reconfiguration without losing data or machine state supports field updates and adaptive operation.
• Low-power operation – Series-level standby and operating current characteristics are optimized for low-power embedded use; AT6002 devices document typical operating currents at modest levels.
• Consistent pinout for migration – AT6000 series devices share consistent pin locations to simplify migration between densities within the family.
