• Core Logic — 17,000 logic elements (LEs) for implementing combinational and sequential logic.
• Memory — Approximately 0.7 Mbits of embedded block RAM (716,800 bits total) plus distributed RAM resources for buffering, FIFOs and on-chip storage.
• DSP Resources — Enhanced sysDSP architecture with dedicated multipliers; device-level configuration indicates support for 24 × 18×18 multipliers for high-performance multiply/accumulate operations.
• Embedded SERDES — Family SERDES support from 150 Mbps to 3.2 Gbps and 256-FTBGA package configuration provides 4 SERDES channels alongside 133 I/Os for high-speed serial links.
• Clocking and Timing — On-chip clock management including DLLs and PLLs (2 DLLs and up to 2 PLLs for this device selection) to support phase and frequency control for system timing.
• I/O and Interfaces — 133 user I/Os in the 256-FTBGA package with programmable I/O buffer options and source-synchronous support for a variety of parallel and serial interfaces.
• Power — Core supply range specified at 1.14 V to 1.26 V to match system power-rail requirements.
• Package & Environmental — 256-ball FTBGA (17 × 17 mm) package; industrial grade with operating temperature range of −40 °C to 100 °C and RoHS compliance.
• Configuration & System Support — Family-level configuration features include SPI boot flash interface, dual-boot images and on-chip oscillator for initialization and general use.

Typical Applications

• Industrial Control — Implement motion control, protocol bridging and deterministic I/O processing using the device’s logic elements, DSP resources and industrial temperature range.
• Communications & Networking — Support medium-speed serial links and protocol interfaces with built-in SERDES channels and flexible I/O standards.
• Signal Processing — Use sysDSP slices and dedicated multipliers for filtering, accumulation and other real-time signal processing tasks.
• Embedded System Glue Logic — Integrate peripheral interfaces, custom control logic and memory buffering to reduce BOM and board-level complexity.

Unique Advantages

• Balanced Logic Density: 17,000 logic elements provide a mid-range capacity that fits compact but feature-rich embedded designs without overspecifying resources.
• Integrated High-Speed I/O: 133 user I/Os with the 256-FTBGA package and family SERDES support enable both parallel and serial interfacing from a single device.
• On-chip DSP Acceleration: Dedicated multipliers and sysDSP architecture accelerate math-intensive workloads and offload processing from the host MCU or CPU.
• Industrial Temperature Range: Rated for −40 °C to 100 °C, suitable for a wide range of industrial environments and deployment scenarios.
• Flexible Boot & Configuration: SPI boot flash, dual-boot image support and on-chip oscillator simplify system bring-up and field updates.
• Compact, Manufacturable Package: 256-FTBGA (17 × 17 mm) package balances board area and I/O accessibility for production designs.
