Key Features

• Core Capacity  Approximately 500,000 equivalent system gates and 8,064 logic elements for mid-to-high density logic integration.
• Embedded Memory  Approximately 0.074 Mbits of on-chip RAM (73,728 bits) to support embedded FIFOs and local data buffering.
• I/O Flexibility  115 user I/Os with Axcelerator family multi-standard support including bank-selectable I/Os and support for single-ended and differential standards as described in the Axcelerator family documentation.
• Clocking and PLLs  Segmentable clock resources and embedded PLL capability (family-level specifications include 14–200 MHz input range and frequency synthesis capability) for flexible timing and high-frequency internal operation.
• Performance  Family-level performance characteristics include high internal and system switching capability suitable for designs requiring elevated clock rates and throughput.
• Package & Mounting  208-BFCQFP with tie bar (supplier device package: 208-CQFP, 75 × 75) in a surface-mount form factor for board-level assembly.
• Power  Core supply specified 1.425 V to 1.575 V, consistent with the 1.5 V family core operation.
• Rugged Operating Range  Military-grade device with operating temperature range from −55 °C to 125 °C.
• Design Security & Diagnostics  Antifuse, nonvolatile architecture and family-level FuseLock programming technology to protect against reverse engineering, plus in‑system diagnostic and debug capability provided by Microchip tools.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Aerospace and Defense Systems  Use as mission-critical processing and I/O glue logic where military temperature range, nonvolatile configuration and design security are required.
• High-Speed Communications  Deploy for protocol bridging, line cards or custom SERDES-adjacent logic leveraging the family’s high-performance I/O capabilities and embedded FIFOs.
• Secure Embedded Processing  Implement application-specific processing and control while protecting intellectual property with the antifuse programming and FuseLock protections.
• Industrial and Ruggedized Equipment  Integrate into rugged control and instrumentation platforms that require broad temperature tolerance and long-term field-configurable logic.

Unique Advantages

• Nonvolatile, One-Time Programmable Architecture: Antifuse-based single-chip configuration eliminates the need for external configuration memory and ensures persistent, tamper-resistant operation.
• Design Security (FuseLock): Programming technology specifically intended to protect designs against reverse engineering and unauthorized readout.
• High-Density Logic in a Compact Package: 8,064 logic elements and 500k equivalent gates in a 208-pin CQFP footprint reduce board-level routing and simplify mid-density system designs.
• Rugged Temperature and Military Grade: Specified for −55 °C to 125 °C operation and listed as Military grade for applications with strict environmental requirements.
• On-Chip Memory and FIFO Support: Embedded RAM (73,728 bits) and family-level FIFO control logic reduce external memory dependency for buffering and streaming data paths.
• Vendor Diagnostic Ecosystem: In-system diagnostic and debug capability available through Microchip’s Silicon Explorer tooling for validation and troubleshooting.
