AT6005A-2AC

The AT6005A-2AC is an SRAM-based Field Programmable Gate Array (FPGA) from the AT6000(LV) family, offered by Microchip Technology. The device provides 15,000 usable gates across 3,136 logic-element cells and up to 108 user I/O pins in a 144-LQFP (20×20) surface-mount package.

Designed for reconfigurable coprocessor and compute‑intensive logic applications, this FPGA supports system speeds greater than 100 MHz and features architecture and clocking options intended for adaptive hardware and hardware acceleration tasks.

Key Features

• Core Logic — 3,136 logic-element cells delivering approximately 15,000 usable gates and a maximum of 3,136 registers for implementing mid-density logic functions.
• Performance — 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 as documented for the AT6000(LV) series.
• I/O Flexibility — 108 user I/Os with independently configurable I/O options, TTL/CMOS input thresholds, open‑collector/tristate outputs, programmable slew‑rate control, and up to 16 mA drive per I/O (combinable to 64 mA).
• Reconfiguration — Supports complete and partial in‑system reconfiguration with no loss of data or machine state, enabling adaptive hardware and on‑the‑fly updates.
• Clocking and Timing — Independently controlled column clocks and resets with chip clock skew less than 1 ns for synchronized multi-column designs.
• Power and Supply — Operates at 5.0 V (VCC = 4.75 V to 5.25 V); typical operating current for the AT6005 device is documented in the series as approximately 40–80 mA, with low standby currents shown for the family.
• Package and Mounting — 144-LQFP (20×20) surface-mount package for compact board integration.
• Commercial Temperature Grade — Rated for commercial operation from 0 °C to 70 °C.
• Compliance — RoHS compliant.

Typical Applications

• Reconfigurable Coprocessors — Implement hardware-accelerated functions and offload compute‑intensive tasks using the device’s mid-density logic and fast clocking.
• Hardware Acceleration — Deploy adaptive algorithms and cache-logic-style acceleration for performance‑sensitive signal or data processing workloads.
• High-Speed Logic and Control — Use the AT6005A-2AC for timing-critical control paths and custom protocol handling where deterministic delays and independent column clocks are beneficial.
• Prototyping and In‑System Updates — Partial and full in‑system reconfiguration lets engineers iterate designs and update logic without losing machine state.

Unique Advantages

• Balanced Logic Density: 3,136 cells and 15,000 gates provide a mid-range capacity suited to complex, compute‑focused subsystems without unnecessary die size.
• Deterministic Timing: Documented input/output delays and low inter-column clock skew support tightly timed designs and synchronized multi-column logic.
• Flexible I/O: Independently configurable I/O with selectable thresholds and programmable slew-rate enables interfacing to a variety of TTL/CMOS signaling environments.
• In‑System Reconfiguration: Complete and partial reconfiguration capabilities let systems adapt in the field and preserve machine state during updates.
• Compact Packaging: 144‑LQFP (20×20) surface‑mount package simplifies board layout and supports denser system integration.
• Commercial-grade Reliability: Rated for 0 °C to 70 °C operation and RoHS compliant for mainstream electronics applications.
