AT6002A-4AI

The AT6002A-4AI is an SRAM-based Field Programmable Gate Array in Microchip Technology’s AT6000(LV) family. The device implements a symmetrical array of small, efficient logic cells with a flexible busing network, designed for reconfigurable coprocessors and compute-intensive logic.

Targeted for industrial applications, this surface-mount 144-LQFP device delivers logic density and I/O flexibility with a 4.5 V to 5.5 V supply range and an operating temperature range of −40 °C to 85 °C.

Key Features

• Core Performance System speeds greater than 100 MHz and flip-flop toggle rates above 250 MHz. Measured input and output timing: input delay ~1.2 ns/1.5 ns and output delay ~3.0 ns/6.0 ns as documented for the series.
• Logic Capacity 1,024 logic elements (cells) delivering approximately 6,000 usable gates and a maximum of 1,024 registers for combinational and sequential logic implementation.
• I/O and Interface Flexibility 95 user I/O pins; series-level I/O features include independently configurable I/O with TTL/CMOS input thresholds, open-collector/tristate outputs, programmable slew-rate control and per-pin drive options (I/O drive 16 mA, combinable to 64 mA).
• Reconfiguration and Design Flow Supports complete and partial in-system reconfiguration with no loss of data or machine state, enabling adaptive hardware and on-the-fly function updates.
• Power Voltage supply range 4.5 V to 5.5 V. Typical operating current range for the AT6000 series is 15–170 mA, with standby current options noted at 500 µA / 200 µA in the series documentation.
• Memory Device contains 0 bits of embedded RAM; design resources focus on logic elements and registers for implementing state and functions.
• Package & Environmental 144-LQFP (20 × 20 mm) surface-mount package, industrial-grade device with RoHS compliance and an operating temperature of −40 °C to 85 °C.

Typical Applications

• Reconfigurable Coprocessors Offload compute-intensive tasks from a host processor by implementing custom acceleration functions in FPGA logic and registers.
• Hardware Acceleration and Adaptive Logic Implement adaptive hardware blocks and cache-style logic to accelerate algorithms and dynamically change functionality through in-system reconfiguration.
• Industrial Control and I/O Interfacing Use the device’s industrial temperature rating and flexible I/O options for control logic, protocol bridging, and high-density interfacing in industrial systems.

Unique Advantages

• Predictable, high-speed operation: Series-documented system speeds >100 MHz and high flip-flop toggle rates enable responsive logic and control paths.
• Flexible, high-drive I/O: 95 user I/Os with configurable thresholds and programmable slew-rate allow integration with a wide variety of external devices and bus standards.
• In-system reconfiguration: Complete and partial reconfiguration without loss of state supports field updates and adaptive hardware strategies.
• Compact, industry-ready package: 144-LQFP surface-mount format and −40 °C to 85 °C rating make the device suitable for industrial deployments.
• Efficient, routed architecture: Symmetrical cell array and layered busing network provide efficient routing and predictable placement for repeatable design migration across the AT6000 family.
• Low standby and controlled operating current: Series standby and operating current figures support lower-power designs where applicable.
