Key Features

• Logic Capacity — 151,824 logic elements (registers) available for complex digital designs and large‑scale integration.
• On‑chip Memory & DSP — Approximately 5,325 bits of embedded RAM plus embedded multiply‑accumulate blocks for DSP workloads and signal processing up to 300 MHz.
• High‑performance Fabric — Each logic element includes a 4‑input LUT (LUT4) with fast carry chains; fabric operates at design frequencies up to 300 MHz as documented.
• SerDes and Memory Interfaces — Integrated high‑speed serial interfaces (3.125 Gbps native SerDes) and support for DDR2/DDR3/LPDDR memory controllers for high‑throughput IO and external memory access.
• I/O and Packaging — 166 user I/O pins in a 352‑BFCQFP exposed‑pad package (supplier package: 352‑QFP, 48×48), optimized for surface‑mount assembly.
• Power & Operating Range — Nominal core supply range 1.14 V to 1.26 V; rated for operating temperatures from −55 °C to +125 °C.
• System Reliability — Flash‑based configuration with design‑level hardening against radiation‑induced single‑event upsets (SEUs), suitable for radiation‑aware systems.
• Compliance — RoHS compliant.

Typical Applications

• Space and Satellite Systems — Radiation‑hardened architecture and SEU‑resistant configuration make this FPGA suited for LEO/MEO/GEO/HEO and deep‑space electronics.
• High‑Altitude Aviation — Wide temperature range and hardened configuration support avionics and high‑altitude sensor/communication subsystems.
