Key Features

• Core Capacity  250,000 equivalent system gates and 4,224 logic elements provide a compact programmable fabric for mid‑density logic implementations.
• Embedded Memory  55,296 total RAM bits (approximately 55 kbits) with embedded FIFO control logic for buffering and data-path applications.
• I/O Flexibility  138 user I/Os with support for mixed-voltage operation and high-speed differential interfaces; LVDS-capable channels up to 700 Mb/s as provided by the Axcelerator family.
• High-Speed Clocking and PLLs  Embedded phase-locked loop (PLLs) with a 14–200 MHz input range and frequency synthesis capability up to 1 GHz (Axcelerator family specification) to support high-performance timing requirements.
• Performance  Family-level performance characteristics include 350+ MHz system performance and 500+ MHz internal performance as specified for Axcelerator devices.
• Power  Core supply range of 1.425 V to 1.575 V (1.5 V nominal) for low-voltage core operation.
• Package and Mounting  256-ball LBGA surface-mount package (supplier package: 256-FPBGA, 17 × 17 mm) for high-density board integration.
• Industrial Temperature Range  Rated for operation from −40 °C to 85 °C to meet industrial environmental requirements.
• Security and Test  FuseLock programming technology for design protection and IEEE 1149.1 (JTAG) boundary-scan support for board-level testing; unique in‑system diagnostic and debug capability with Microchip Silicon Explorer II.
• Standards and Configurability  Bank-selectable I/Os and support for multiple single-ended and differential I/O standards across mixed-voltage banks (Axcelerator family capability).

Typical Applications

• Industrial Control  Implement motor control, PLC logic, and deterministic control functions using the device’s industrial temperature rating, deterministic timing, and embedded memory resources.
• High‑Speed Communications  Use LVDS-capable I/Os and embedded FIFOs to handle high-speed serial interfaces and data buffering in communication modules and backplane interfaces.
• Embedded Systems  Integrate custom datapaths, protocol handling, and interface bridging where nonvolatile configuration and mid-density logic capacity are required.
• Test & Measurement  Take advantage of boundary-scan (JTAG) and in-system diagnostics for instrument control, data acquisition front-ends, and automated test applications.

Unique Advantages

• Nonvolatile, single‑chip solution: Eliminates the need for separate configuration memory by using antifuse technology for permanent on-chip configuration.
• High-speed timing resources: On-chip PLLs and segmentable clock resources enable deterministic, high-performance designs with flexible clocking options.
• Flexible mixed-voltage I/O: Bank-selectable I/O standards and programmable drive/slew options simplify interfacing with a wide range of external devices.
• Security by design: FuseLock programming technology protects designs against reverse engineering and unauthorized duplication.
• Debug and test support: Built-in IEEE 1149.1 boundary-scan and Microchip Silicon Explorer II support streamline in-system debug and manufacturing test.
• Industrial-rated robustness: Specified for −40 °C to 85 °C operation and RoHS-compliant construction for deployment in industrial applications.
