AT6005ALV-4AC

The AT6005ALV-4AC is an SRAM-based Field Programmable Gate Array (FPGA) from the AT6000(LV) series, offered in a 144-LQFP (20×20) surface-mount package. It provides 3,136 logic cells (equivalent to 15,000 usable gates) and 108 user I/Os, delivering a compact reconfigurable logic device for compute‑intensive and adaptive hardware tasks.

Designed for high-speed logic implementation, the device supports system speeds greater than 100 MHz and flip‑flop toggle rates above 250 MHz. It operates from a 3.135 V to 3.465 V supply and is specified for commercial temperature operation from 0 °C to 70 °C. The device is RoHS compliant.

Key Features

• Core architecture Symmetrical array of 3,136 cells (56 × 56 rows × columns) implementing 15,000 usable gates and up to 3,136 registers for on-chip state and buffering.
• High-performance timing System speeds > 100 MHz, flip‑flop toggle rates > 250 MHz, input delays of 1.2 ns / 1.5 ns and output delays of 3.0 ns / 6.0 ns for deterministic timing behavior.
• Flexible clocking and reset Independently controlled column clocks and column resets with clock skew less than 1 ns across the chip for synchronized, low-skew designs.
• Configurable I/O 108 user I/Os with TTL/CMOS input thresholds, open-collector/tristate outputs, programmable slew-rate control and base I/O drive of 16 mA (combinable up to 64 mA).
• Low-power operation Typical operating currents for the AT6005 family are specified (40–80 mA for AT6005) with very low standby currents reported at the series level, enabling energy-efficient designs.
• Package and mounting 144-LQFP (20 × 20) surface-mount package suitable for compact board-level integration; commercial grade operating temperature of 0 °C to 70 °C.
• Development support Series supports PC- and workstation-based integrated development tools for design entry and implementation (Atmel Integrated Development System referenced in series documentation).

Typical Applications

• Reconfigurable coprocessors Implement hardware-accelerated functions and offload compute-intensive tasks using the device’s dense logic cell array and high-performance timing.
• Adaptive hardware and cache logic Deploy adaptive or cache-style logic that can be reconfigured in-system to respond to changing algorithmic needs without losing machine state.
• High-speed I/O interfacing Use programmable I/O thresholds, drive strengths and slew-rate control to interface with a variety of TTL/CMOS peripherals and custom I/O functions.
• Custom logic and state machines Build complex state machines and custom hard-macro functions using the provided registers and reusable component generators supported by the series tools.

Unique Advantages

• Deterministic, low-skew clocking: Independently controlled column clocks and resets with < 1 ns skew enable tight timing across the array for synchronized, high-performance designs.
• High logic density in a compact package: 3,136 cells and 15,000 usable gates in a 144-LQFP provide a balance of functionality and board-space efficiency.
• Programmable, robust I/O: TTL/CMOS thresholds, open-collector/tristate options and adjustable drive/slew control simplify interfacing and reduce external component counts.
• Fast signal paths: Measured input/output delays and high toggle rates support designs that require rapid combinational and sequential response.
• Commercial-grade readiness: Operates over a 0 °C to 70 °C range with specified supply window of 3.135 V to 3.465 V, suitable for general embedded and electronics applications.
