• Embedded Memory & FIFOs – 73,728 bits of on-chip RAM arranged in variable-aspect 4,608-bit RAM blocks and programmable embedded FIFO control logic for efficient data buffering and packet handling.
• High‑Performance I/Os – 317 user I/Os with 700 Mb/s LVDS-capable channels and support for mixed-voltage operation (1.5V, 1.8V, 2.5V, 3.3V); bank-selectable I/Os with programmable slew rate, drive strength and input pull options.
• Clocking & PLL – Segmentable clock resources and embedded PLLs with 14–200 MHz input range and frequency synthesis capabilities up to 1 GHz for flexible clock management.
• Nonvolatile, Secure Programming – Antifuse-based single-chip nonvolatile solution with FuseLock programming technology to protect design intellectual property.
• System Reliability & Test – Deterministic, user-controllable timing, IEEE 1149.1 (JTAG) boundary-scan support, and in-system diagnostic capability through Microchip Silicon Explorer II.
• Packaging & Power – Surface-mount 484-FPBGA (23 × 23 mm) package; core supply range 1.425 V to 1.575 V (1.5 V nominal). Mounting type: surface mount.
• Commercial Grade & Environmental – Commercial temperature range 0 °C to 70 °C and RoHS compliant.

Typical Applications

• High‑speed communications interfaces – Use LVDS-capable I/Os and high-speed internal performance to implement protocol bridging and serializer/deserializer front ends.
• Data buffering and packet processing – Embedded RAM blocks and high-performance FIFOs enable on-chip packet buffering, rate adaptation and pipeline staging.
• Secure single‑chip implementations – Antifuse nonvolatile programming and FuseLock help protect IP in designs that require in-field permanence and anti-reverse-engineering measures.
• Timing‑sensitive control systems – Deterministic timing resources, segmentable clocks and integrated PLLs provide stable, user-controlled timing for real-time and synchronous designs.

Unique Advantages

• Single‑chip nonvolatile solution: Eliminates external configuration memory and simplifies system startup with antifuse-based programming.
• High internal and system throughput: Documented 500+ MHz internal performance and 350+ MHz system performance support demanding logic and data-path requirements.
• Flexible, multi‑standard I/Os: Bank-selectable support for multiple voltage standards and high-speed LVDS/LVPECL channels reduces the need for level‑shifters and external transceivers.
• Programmable clocking and PLL synthesis: Embedded PLLs and segmentable clocks allow on-chip frequency synthesis up to 1 GHz and fine-grained clock distribution.
• Embedded memory and FIFO control: Dedicated RAM blocks and FIFO logic reduce external memory dependencies and simplify data-flow designs.
• Security and design protection: Antifuse technology with FuseLock programming guards against reverse engineering and protects IP integrity.
