AX250-FGG256

The AX250-FGG256 is an Axcelerator field programmable gate array (FPGA) IC from Microchip Technology. It is an antifuse-based, single-chip nonvolatile FPGA built on the AX architecture and designed to deliver deterministic timing, design security and high internal performance.

Targeted at designs that require on-chip embedded memory, flexible multi-standard I/Os and high internal clock rates, this commercial-grade device provides secure, nonvolatile programmability with package and power characteristics suited for surface-mount applications.

Key Features

• Core capacity and logic elements – Approximately 250,000 equivalent system gates with 4,224 logic elements.
• Embedded memory – 55,296 bits of on-chip RAM (approximately 0.055 Mbits) with support for variable-aspect 4,608-bit RAM blocks and programmable embedded FIFO control logic.
• I/O and multi-standard interface support – 138 user I/Os; family-level support for mixed-voltage bank operation (1.5V, 1.8V, 2.5V, 3.3V) and differential standards including LVDS with 700 Mb/s capability.
• High-performance timing – Family-level published performance includes 350+ MHz system performance and 500+ MHz internal performance, segmentable clock resources and embedded PLLs with frequency synthesis capabilities.
• Security and diagnostics – FuseLock programming technology to protect against reverse engineering and built-in in-system diagnostic and debug capability referenced in the Axcelerator family documentation.
• Package, power and mounting – 256-LBGA package (supplier device package 256-FPBGA, 17×17), surface-mount mounting, and a core voltage supply range of 1.425 V to 1.575 V.
• Commercial operating range and compliance – Commercial grade with an operating temperature of 0 °C to 70 °C and RoHS compliance.

Typical Applications

• High-speed protocol bridging – Use the device’s high internal performance and LVDS-capable I/Os for protocol conversion and high-speed interface implementation.
• Embedded FIFO and buffering – Leverage on-chip RAM and embedded FIFO control logic for packet buffering, stream alignment and data rate matching.
• Custom logic and system glue – Implement application-specific datapaths, control logic and timing-critical modules where deterministic timing is required.
• Secure, nonvolatile designs – Apply FuseLock programming technology for designs that require on-chip nonvolatile programmability and protection against reverse engineering.

Unique Advantages

• Nonvolatile single-chip solution: Antifuse-based Axcelerator architecture provides one-time programmable, nonvolatile logic in a single component, simplifying design for secure applications.
• High internal performance: Documented family-level internal and system performance numbers support timing-critical logic and high-throughput data paths.
• Flexible I/O standards: Mixed-voltage bank operation and multi-standard support reduce external level-shifting and simplify board-level interfacing.
• On-chip memory and FIFO support: Embedded RAM and programmable FIFO control logic enable local buffering and width-conversion without external memory.
• Design protection: FuseLock programming technology and in-system diagnostic features enhance IP protection and aid bring-up and debug.

Why Choose AX250-FGG256?

AX250-FGG256 combines a substantial logic capacity (approximately 250k equivalent gates) with embedded memory, flexible I/O and antifuse nonvolatile programmability to address designs that demand secure, deterministic FPGA behavior. Its family-level performance characteristics and embedded PLLs make it suitable where internal timing and high-speed interfacing matter.

This commercial-grade device is a practical choice for engineers building communication interfaces, embedded buffering systems and custom logic implementations that benefit from a single-chip, protected FPGA solution with surface-mount 256-LBGA packaging and RoHS compliance.
