• Logic Resources  1,024 logic elements (cells) and approximately 30,000 gates to implement medium-density logic and control functions.
• Embedded Memory (FreeRAM)  Approximately 8,192 bits of distributed, flexible SRAM supporting single/dual-port and synchronous/asynchronous configurations for FIFOs, scratch pads and coefficient storage.
• Arithmetic Performance  Fast array multipliers (series-level >50 MHz) and a cell structure optimized for efficient vector/array multiplication tasks.
• I/O and Interface Capability  256 I/O pins with programmable output drive and PCI-compliant I/O options (series-level), enabling broad interface flexibility; 5 V I/O tolerant (series-level).
• Clocking  Eight global clocks with low-skew distribution and programmable edge transitions plus additional dedicated PCI clocks (series-level) for complex timing requirements.
• Package & Mounting  352-LBGA (352-SBGA, 35×35) surface-mount package for high pin-count, space-efficient PCB designs.
• Power & Temperature  Supply voltage range 3.0 V to 3.6 V; commercial operating temperature 0 °C to 70 °C.
• Compliance  RoHS compliant.

Typical Applications

• DSP Acceleration  Implements FIR filters, FFTs and other arithmetic-intensive functions using on-chip RAM and array multipliers for real-time signal processing.
• Multimedia Processing  Supports video compression/decompression and discrete-cosine transform implementations where reconfigurable logic and embedded memory improve throughput.
• Coprocessor for Embedded Systems  Offloads compute-heavy algorithms from processors by providing dedicated, reconfigurable logic and memory resources.
• PCI-Compatible Interface Designs  Suitable for systems requiring PCI-compliant I/Os and flexible pin assignments in a compact BGA package.

Unique Advantages

• Dynamic Reconfiguration (Cache Logic)  Series-level Cache Logic enables partial or full in-system reconfiguration without data loss, supporting adaptive designs and fast updates.
• Flexible On-Chip Memory  Distributed 10 ns SRAM (FreeRAM) lets you create multiple independent RAM blocks without consuming separate logic resources, simplifying memory-intensive designs.
• High I/O Density  256 I/O pins in a 352-ball BGA allow dense board-level connectivity while preserving package footprint.
• DSP-Friendly Primitives  Built-in array multiplier capability and cell-to-cell routing facilitate efficient implementation of arithmetic kernels used in multimedia and signal processing.
• Industry Tool Support (Series)  The family is designed for use with industry-standard design flows and automatic component generators (series-level), easing synthesis, placement and routing.
