Key Features

• Core Logic — 640 logic elements and 80 logic blocks provide the capacity for glue logic, state machines and control functions.
• I/O Density — 159 I/Os available in a 256-ball package enable dense peripheral and bus connections without larger packages.
• Non-volatile, Instant-on Architecture — Single-chip non-volatile implementation enables microsecond power-up and eliminates the need for external configuration memory.
• Reconfiguration and Programming — Supports background programming and in-field updates; SRAM-based logic can be reconfigured in milliseconds via supported programming interfaces.
• Embedded and Distributed Memory — Approximately 6.1 Kbits of distributed RAM for small embedded storage and buffering tasks.
• Flexible I/O Buffering — Family-level support for a wide range of interfaces including LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL and differential standards as listed in the device family documentation.
• Power and Sleep Modes — Core voltage specified at 1.14 V to 1.26 V and a sleep mode capability that reduces static current by up to 100× as documented for the MachXO family.
• Package and Mounting — Surface-mount 256-LBGA; supplier device package specified as 256-FTBGA (17 × 17 mm) for compact board integration.
• Commercial Temperature Range — Rated for 0 °C to 85 °C operation to suit a wide range of commercial applications.
• Standards and Tool Support — Family documentation references IEEE 1149.1 boundary scan and ispLEVER design tool support for synthesis, place-and-route and timing verification.

Typical Applications

• Glue Logic and System Control — Implement address decoding, bus arbitration and control-state machines using the device’s logic resources and instant-on capability.
• Bus Bridging and Interface Conditioning — Use the high I/O count and flexible I/O standards to bridge or condition signals between subsystems and external peripherals.
• Power-up and Reset Sequencing — Leverage single-chip non-volatile configuration and fast start-up for reliable power-up control and sequencing logic.
• Field Upgradeable Logic — Perform in-field firmware and logic updates with background programming and TransFR-style reconfiguration supported in the MachXO family.

Unique Advantages

• Single-Chip Non-volatile Solution: Eliminates external configuration memory and reduces BOM and board area compared with multi-chip configurations.
• Fast, Predictable Start-up: Instant-on architecture provides immediate availability of implemented logic after power-up, improving system responsiveness.
• High Pin-to-Logic Ratio: 159 I/Os alongside 640 logic elements enable dense I/O designs without moving to larger, more expensive packages.
• Low-Power Options: Documented sleep mode capability significantly reduces static current for power-sensitive applications.
• Compact Surface-Mount Package: 256-LBGA (256-FTBGA 17×17 mm) offers a small footprint for space-constrained PCBs while maintaining robust I/O.
• Design Ecosystem Support: Family-level support for boundary scan and ispLEVER toolchain simplifies design, verification and in-system programming workflows.
