• I/O Density & Standards – 336 user I/Os with bank-selectable, mixed-voltage operation (1.5V, 1.8V, 2.5V, 3.3V) and support for single-ended and differential standards including LVDS and LVPECL.
• Performance – Family-level performance guidance including 350+ MHz system performance and 500+ MHz internal performance for demanding timing requirements.
• Programmable Clocking & PLL – Segmentable clock resources and an embedded PLL with a 14–200 MHz input range and frequency synthesis capability up to 1 GHz.
• Nonvolatile Antifuse Technology – Antifuse-based single-chip solution with FuseLock programming technology to protect against reverse engineering and secure designs.
• Package & Mounting – 676-FBGA (27 × 27 mm) package; surface-mount mounting type suitable for industrial PCBs.
• Power & Temperature – Core supply range 1.425 V to 1.575 V and rated for industrial operation from −40 °C to +85 °C.
• Design-for-Test & Debug – Boundary-scan (IEEE 1149.1/JTAG) and in-system diagnostic capability with Microchip Silicon Explorer II (family feature).
• Standards & Flexibility – Bank-selectable I/Os (8 banks per chip), programmable slew rate/drive strength and input pull options for board-level signal integrity tuning.
• Regulatory – RoHS compliant.

Typical Applications

• Industrial Control & Automation – Deterministic timing, industrial temperature rating, and nonvolatile antifuse programming make the device well-suited for control logic, sequencing and safety-related modules.
• High-Speed Serial & Communication Interfaces – LVDS-capable I/Os and embedded PLLs support high-speed data paths and protocol bridging in communications equipment.
• Embedded Memory-Intensive Logic – Configurable embedded SRAM blocks and programmable FIFO control enable buffer-heavy designs such as data-acquisition front-ends and streaming interfaces.
• Secure, One-Time Programmable Designs – Antifuse technology with FuseLock provides a nonvolatile, single-chip option where design security and IP protection are required.

Unique Advantages

• Single-Chip, Nonvolatile Implementation: Eliminates external configuration memory by using antifuse programming for permanent on-chip configuration.
• Secure Programming with FuseLock: Built-in protection against reverse engineering supports IP security for sensitive designs.
• Flexible, Multi-Standard I/Os: Bank-selectable mixed-voltage operation and support for multiple single-ended and differential standards reduce the need for level-shifting components.
• High Internal and System Performance: Family-specified 350+ MHz system and 500+ MHz internal performance allow timing headroom for demanding logic and data paths.
• Embedded Memory & FIFO Support: Configurable RAM blocks and FIFO control logic simplify designs that require data buffering and width conversion.
• Industrial Grade Reliability: Industrial temperature range (−40 °C to +85 °C) and a robust BGA package support deployment in industrial environments.
