Key Features

• Logic Capacity — 6,864 logic elements provide configurable resources for glue logic, state machines, and moderate-complexity custom logic implementations.
• Embedded Memory — Approximately 0.246 Mbits of on-chip RAM (245,760 bits) for FIFOs, buffers, and small data stores.
• High I/O Count — 335 general-purpose I/Os to support extensive peripheral connectivity and multi-interface designs.
• Non-volatile, Multi-time Programmable — MachXO3 family architecture provides non-volatile configuration with multi-time programmability for in-field updates and configuration flexibility.
• Flexible I/O and Clocking — Family-level features include flexible on-chip clocking and configurable I/O buffers to support a range of interface requirements.
• Embedded Hardened IP — Series datasheet documents embedded IP functions (for example I2C, SPI, timers) to simplify common system functions.
• Package and Mounting — 400-LFBGA (supplier package: 400-CABGA, 17×17) in a surface-mount form factor for compact board integration.
• Industrial Temperature and Power — Rated for −40 °C to 100 °C operation and supplies from 2.375 V to 3.465 V for robust industrial use.
• Standards and Compliance — RoHS compliant to meet current lead-free environmental requirements.

Typical Applications

• Industrial Control — Implement control logic, interface aggregation, and protocol bridging in industrial equipment using the device’s industrial temperature rating and high I/O count.
• System Glue Logic — Replace discrete glue components by consolidating control, sequencing, and interface adaptation into the FPGA’s logic fabric and embedded memory.
• I/O Expansion and Bridging — Use the 335 I/Os to connect multiple peripherals and translate between interfaces while maintaining a small PCB footprint.
• Configuration and System Supervision — Take advantage of non-volatile, multi-time programmable configuration for in-field updates and system-level configuration storage.

Unique Advantages

• High integration density: 6,864 logic elements and on-chip memory reduce BOM and simplify board-level design by integrating logic, buffering, and small data storage.
• Large peripheral connectivity: 335 I/Os enable direct connection of many sensors, actuators, and interface chips without additional expanders.
• Industrial robustness: Rated for −40 °C to 100 °C operation and RoHS compliant for deployment in industrial environments.
• Compact packaging: 400-LFBGA (400-CABGA, 17×17) provides a space-efficient solution for high-pin-count designs.
• Reconfigurable, non-volatile operation: Multi-time programmable non-volatile configuration supports field updates and flexible system configuration strategies.
• Family-level system features: MachXO3 family capabilities—such as flexible clocking, configurable I/O buffers, and embedded IP—help accelerate development and integration.
