AT40K10AL-1AJC

The AT40K10AL-1AJC is an SRAM-based FPGA from the AT40KAL family designed for high-performance, reconfigurable logic. It provides 576 logic elements, 4,608 bits of distributed on-chip RAM, and 62 user I/Os in an 84-pin PLCC (J‑lead) package for surface-mount assembly.

This device targets applications requiring in-system reconfigurability, embedded SRAM, and moderate gate counts (approximately 20,000 gates), offering features drawn from the AT40KAL series such as 10 ns flexible SRAM, Cache Logic reconfiguration, and multi-clock support.

Key Features

• Core Architecture  SRAM-based FPGA with Cache Logic dynamic full/partial reconfigurability as described for the AT40KAL series.
• Logic Capacity  576 logic elements (cells) providing roughly 20,000 gates of logic capacity.
• Embedded Memory (FreeRAM)  4,608 bits of distributed, 10 ns flexible SRAM suitable for single- or dual-port synchronous/asynchronous memory functions.
• I/O  62 user I/Os with programmable output drive characteristics as part of the family feature set.
• Clocking  Family-level support includes fast, low-skew global clock distribution (8 global clocks in the AT40KAL family).
• Performance  Series-level system speeds to 100 MHz and array multipliers capable of >50 MHz as documented for AT40KAL devices.
• Power and Voltage  Supply voltage 3.0 V to 3.6 V; family documentation also indicates 5 V I/O tolerance where supported.
• Package & Mounting  84‑lead LCC (J‑lead) / 84‑PLCC supplier package (29.31 × 29.31 mm), surface-mount mounting.
• Operating Conditions & Compliance  Commercial-grade device rated for 0 °C to 70 °C operation and RoHS compliant.

Typical Applications

• DSP and Coprocessing  Implements arithmetic intensive functions such as FIR filters and FFT cores where on-chip RAM and reconfigurability accelerate processing.
• Video and Multimedia Processing  Supports convolution, DCT, and other transforms using the family’s fast array multipliers and distributed SRAM.
• Prototyping and Adaptive Logic  In-system reconfigurability (Cache Logic) enables rapid design changes and adaptive algorithms for evolving prototypes or field updates.
• Custom Control and Interface Logic  Useful for glue logic, protocol bridging, and user-interface control where moderate logic density and flexible I/O are required.

Unique Advantages

• On-chip, High-speed SRAM: Distributed 10 ns FreeRAM lets you implement FIFOs and scratchpad memories without consuming separate memory ICs, reducing BOM and board area.
• Dynamic Reconfiguration: Cache Logic capability from the AT40KAL family enables partial or full reconfiguration in-system for adaptive designs and fast updates.
• Balanced Logic and Memory: 576 logic elements combined with 4,608 bits of embedded RAM provides an efficient mix for mid-size designs that need both combinational logic and local storage.
• Surface-mount PLCC Packaging: 84‑lead PLCC (J‑lead) in a compact 29.31 × 29.31 mm footprint simplifies board layout for compact assemblies.
• Commercial Temperature Range: Rated for 0 °C to 70 °C operation to match commercial product requirements and development environments.
• RoHS Compliant: Conforms to RoHS requirements for lead-free manufacturing processes.
