AT40K10-2AJI

The AT40K10-2AJI is an SRAM-based FPGA in an 84‑pin PLCC (J‑lead) surface-mount package, designed for industrial applications with a 4.5 V to 5.5 V supply and an operating range of −40 °C to 85 °C. It combines on-chip distributed SRAM, reconfigurable Cache Logic capability and a dense logic fabric to accelerate computation-intensive and adaptive designs.

Engineered for system and DSP coprocessing, multimedia processing and flexible in-system reconfiguration, this device delivers a balance of logic capacity, embedded RAM and I/O for mid-range gate-count FPGA designs.

Key Features

• Core Performance – System speeds up to 100 MHz and array multipliers exceeding 50 MHz; each cell includes internal tri-state capability and 10 ns flexible SRAM timing.
• Embedded Memory (FreeRAM) – 4,608 bits of distributed on-chip SRAM independent of logic elements; supports flexible single/dual-port operation, synchronous or asynchronous access with 10 ns performance.
• Logic Resources – 576 logic elements (cells) supporting approximately 20,000 usable gates for medium-complexity logic functions and datapath implementations.
• I/O and Clocking – 62 I/O pins and architecture-level support for up to 8 global clocks, with options for programmable clock edges, distributed clock shutdown and reset controls.
• Reconfigurability – Cache Logic dynamic full/partial in-system re-configurability with unlimited reprogramming via serial or parallel modes; supports adaptive designs and rapid updates to vector multipliers and coefficients.
• Package & Environmental – Surface-mount 84‑PLCC (J‑lead, 29.31 × 29.31 mm) package; industrial grade with operating temperature −40 °C to 85 °C and RoHS compliance.
• Toolchain & Design Support – Architecture and tooling designed for integration with industry-standard synthesis and simulation environments and automatic component generators for rapid development.

Typical Applications

• DSP & Coprocessing – Implement FIR filters, FFTs, convolvers and other high-throughput arithmetic functions as a coprocessor to offload intensive tasks from a host processor.
• Video and Multimedia Processing – Accelerate video compression/decompression, transforms and data-path operations using the device’s array multipliers and distributed RAM.
• Encryption & Security – Deploy custom cryptographic cores and data-path accelerators that benefit from reprogrammability and embedded SRAM for key and state storage.
• Adaptive and In-System Reconfiguration – Use Cache Logic capability for partial or full in-system updates, enabling adaptive algorithms and fast design iteration without removing the device.

Unique Advantages

• Flexible embedded RAM: Distributed 10 ns FreeRAM allows memory functions (single/dual-port, sync/async) without consuming logic elements, reducing resource contention.
• Deterministic performance: Documented system speeds to 100 MHz and high-speed array multipliers deliver predictable throughput for compute-heavy tasks.
• In-system reconfigurability: Cache Logic and unlimited reprogramming modes enable adaptive designs and quick updates to coefficients and algorithms in the field.
• Industrial-ready packaging and range: Surface-mount 84‑PLCC package with industrial temperature rating supports deployment in temperature-challenging environments.
• Compact mid-range capacity: 576 logic elements and ~20,000 gates offer a balanced option for designers needing moderate gate density with embedded RAM.
• Design ecosystem compatibility: Architecture designed to work with common industry tools and automatic component generators to accelerate implementation and reduce development time.
