Built on the AT40KAL family architecture, this device provides 1,024 logic elements, 8,192 bits of distributed SRAM, and 114 I/O pins, with a supply range of 3.0 V to 3.6 V and commercial operating temperature from 0 °C to 70 °C.

Key Features

• Core Logic 1,024 logic elements (cells) providing approximately 30,000 equivalent gates for implementing combinational and sequential logic.
• Embedded Memory (FreeRAM) 8,192 bits of distributed 10 ns SRAM supporting single- or dual-port, synchronous/asynchronous configurations for FIFOs, scratch pads and small buffers.
• I/O and Voltage 114 I/Os with programmable output drive; device supply 3.0 V to 3.6 V and documented 3.3 V operation with 5 V I/O tolerance (per family datasheet information).
• Clocking and Timing Family-level architecture includes 8 global clocks and low-skew clock distribution features to simplify multi-clock designs and clock domain management.
• Reconfiguration (Cache Logic) Supports dynamic partial or full in-system reconfiguration capability as described for the AT40KAL family, enabling adaptive designs and on-the-fly updates.
• Performance Family-level performance characteristics include system speeds to 100 MHz and array multipliers >50 MHz, with 10 ns flexible SRAM timing for high-speed on-chip storage.
• Package and Mounting 144-LQFP (20 × 20 mm) surface-mount package suitable for standard PCB assembly and compact board-level integration.
• Compliance and Grade Commercial grade device with RoHS compliance for lead-free assembly processes.

Typical Applications

• Signal Processing / DSP Coprocessor Implement FIR filters, FFTs, convolution and other arithmetic functions using the device’s distributed SRAM and array multiplier capabilities.
• Communications Interfaces Use reconfigurable logic and flexible I/O to implement protocol bridging, custom PHY logic or peripheral interfaces in embedded systems.
• Video and Multimedia Acceleration Offload computation-intensive tasks like DCT and image filtering leveraging on-chip RAM and multiplier-friendly cell interconnect.
• Embedded Control and Glue Logic Integrate timing-critical control, peripheral management and custom finite-state machines in compact, reprogrammable silicon.

Unique Advantages
