Key Features

• Core Logic  Approximately 4,300 logic elements suitable for moderate-density programmable logic and glue‑logic tasks.
• Embedded Memory  Approximately 94,208 bits of on-chip RAM for FIFOs, buffering and small data store requirements.
• I/O and Interface Flexibility  58 user I/Os in a 72‑QFN (10×10) exposed pad package, enabling multiple signal interfaces and board-level integration.
• Non‑volatile, Reconfigurable Architecture  MachXO3D family features non‑volatile reconfiguration and TransFR reconfiguration to retain designs without external configuration flash.
• Embedded System Functions  Family-level features include a Dedicated Embedded Security Block, hardened SPI and I²C IP cores, on‑chip oscillator, and user flash memory (UFM) for system control and secure storage.
• Clocking and Timing  Flexible on-chip clocking including PLLs for system clock generation and source-synchronous I/O support.
• Power and Temperature  Wide recommended supply range of 2.375 V to 3.465 V and industrial operating temperature from −40 °C to 100 °C for robust deployment in demanding environments.
• Package and Mounting  72‑VFQFN exposed pad, surface‑mount package (72‑QFN, 10×10) to simplify PCB layout and thermal handling.
• Standards and Testability  Series-level support for IEEE 1149.1 boundary-scan and system-level configuration and test features.

Typical Applications

• Industrial control systems  Leverages industrial temperature grading and flexible I/O to handle interface translation, control sequencing and small-scale logic functions in industrial equipment.
• Security and access control  Built‑in Embedded Security Block and non‑volatile configuration are suitable for secure boot, device authentication and protected configuration storage.
• System glue logic and interface bridging  Moderate logic density and 58 I/Os enable protocol bridging, pin multiplexing and custom interface adaptation between subsystems.
• Configuration and system management  On‑chip UFM, hardened peripherals and on‑chip oscillator support system supervision, configuration storage and simple housekeeping functions.

Unique Advantages

• Highly integrated solution: Combines 4,300 logic elements and approximately 94,208 bits of embedded RAM in a single non‑volatile FPGA to reduce external components and BOM complexity.
• Industrial‑grade robustness: Rated for −40 °C to 100 °C operation and a broad supply range (2.375 V–3.465 V), supporting reliable operation in demanding environments.
• Flexible I/O in compact package: 58 I/Os in a 72‑QFN (10×10) exposed pad package provide multiple interface options while minimizing board area.
• Security and system support: Dedicated Embedded Security Block, UFM and hardened peripheral IP provide on‑device mechanisms for secure configuration and system management.
• On‑chip clocking and timing: Integrated PLLs and source‑synchronous I/O support simplify timing architectures and reduce external clocking requirements.
