AT40K05-2AQC

The AT40K05-2AQC is an SRAM-based Field Programmable Gate Array (FPGA) in the AT40K family optimized for mid‑range logic and embedded memory needs. This surface-mount device provides 256 logic elements, approximately 2,048 bits of distributed on‑chip SRAM, and 78 user I/O pins in a 100‑TQFP (14×14 mm) package. Typical use cases include DSP coprocessing, custom peripheral bridging, and mid‑density logic integration where reprogrammability and on‑chip RAM are important.

Key Features

• Core Logic 256 logic elements (cells) supporting up to 10,000 usable gates for implementing custom logic, state machines, and control functions.
• Distributed SRAM (FreeRAM) Approximately 0.002 Mbits (2,048 bits) of on‑chip, 10 ns distributed SRAM enabling single/dual-port, synchronous or asynchronous memory configurations independent of logic cells.
• High Performance Primitives Series features include array multipliers and fast multiplier support; the family targets system speeds up to 100 MHz and array multiplier performance above 50 MHz.
• I/O and PCI Compatibility 78 I/O pins with 3 V/5 V capable signaling and programmable output drive; family-level documentation references PCI‑compliant I/O architectures and pin‑compatible package options.
• Clocking Family architecture includes multiple global clock resources for low‑skew distribution and flexible clock control (family supports up to 8 global clocks at series level).
• Package and Mounting 100‑TQFP (14×14 mm) surface-mount package suitable for compact PCB layouts and automated assembly.
• Power and Temperature Supply voltage range 4.75 V to 5.25 V and commercial operating temperature range of 0 °C to 70 °C.
• Compliance RoHS compliant.
• Configurable Cell Behavior Family-level features include internal tri‑state capability per cell and support for partial/complete in‑system reconfiguration workflows.

Typical Applications

• DSP Coprocessing Implement fixed‑point FIR filters, FFT stages, and arithmetic accelerators using on‑chip SRAM and array multiplier primitives.
• Custom Peripherals and Interfaces Bridge between processors and external peripherals or implement custom protocol adapters using the device’s 78 programmable I/Os.
• Embedded Control and State Machines Integrate mid‑density control logic and sequencing functions in industrial or commercial electronic systems within the specified operating range.
• Prototyping and In‑System Reconfiguration Use the device’s reprogrammability to iterate hardware‑accelerated functions or update algorithms in the field.

Unique Advantages

• Balanced Logic and Memory: A mix of 256 logic elements and 2,048 bits of distributed SRAM enables both control logic and local data buffering without external memory.
• Reprogrammability: In‑system reconfiguration capability supports design updates and adaptive functionality without replacing hardware.
• Compact, Surface‑Mount Package: 100‑TQFP (14×14) offers a space‑efficient form factor compatible with automated assembly processes.
• Clear Electrical Envelope: Defined 5 V supply range (4.75 V to 5.25 V) and commercial temperature rating simplify BOM and thermal planning for mainstream applications.
• RoHS Compliant: Meets lead‑free environmental requirements for modern electronics manufacturing.

Why Choose AT40K05-2AQC?
