• I/O Flexibility: 68 I/Os with programmable buffer options enable a wide range of interface standards and signal types at the device I/O level.
• Low-Voltage Supply: Single supply operation between 1.14 V and 1.26 V aligns with low-voltage system domains.
• Power and Modes: MachXO2 family features include ultra low power options and instant-on non-volatile configuration (family-level capability documented in the MachXO2 datasheet).
• Embedded System Support: On-chip user flash memory and hardened functions such as SPI, I²C and timers are available in the MachXO2 family (series-level features referenced in the datasheet).
• Package and Mounting: 84‑VFQFN dual-row, exposed pad package (84‑QFN footprint, 7 mm × 7 mm) for surface-mount assembly and thermal/power handling.
• Commercial Temperature Grade: Specified operating temperature range 0 °C to 85 °C for commercial applications.
• RoHS Compliant: Device meets RoHS requirements.

Typical Applications

• Interface and Protocol Bridging: Use the programmable I/Os and on-chip resources to implement board-level protocol translation, bus bridging, and custom interface logic.
• Embedded Control and Timing: Integrate timers, counters, and on-chip flash to implement control functions, sequencers, and non-volatile configuration storage.
• Display and Memory I/O Support: Leverage the MachXO2 family’s pre‑engineered I/O capabilities for display gearings and memory interface control (family-level features documented in the datasheet).
• System Glue and Peripheral Management: Implement glue logic, reset sequencing, and peripheral interfacing in a compact surface-mount FPGA package.

Unique Advantages

• Highly Integrated Mid-Density FPGA: Combines 4,320 logic elements and substantial on-chip RAM to consolidate multiple discrete functions into a single device, reducing BOM and board area.
• Flexible I/O Count and Packaging: 68 configurable I/Os in a compact 84‑VFQFN package provide adaptable connectivity for varied board designs while maintaining a small footprint.
• Low-Voltage Operation: Narrow supply range (1.14 V to 1.26 V) supports low-voltage system domains and simplifies power-tree design for compatible platforms.
• Non-Volatile, Instant-On Behavior (Family Feature): MachXO2 family supports on-chip user flash and instant-on configuration modes for fast startup and field reconfiguration.
• Commercial Temperature and RoHS Compliance: Specified for 0 °C to 85 °C operation and RoHS compliant for broad commercial deployments.
