LCMXO2-256HC-5SG32I

The LCMXO2-256HC-5SG32I is a compact, industrial-grade FPGA from the MachXO2 family designed for low-density control, interface and glue-logic functions. It provides 256 logic elements and 21 I/O pins in a 32‑UFQFN (5×5) exposed-pad package, supporting single-supply operation across a 2.375 V to 3.465 V range and an operating temperature of −40 °C to 100 °C.

As a member of the MachXO2 family, this device benefits from the family’s flexible logic architecture and system-level features such as instant-on configuration and standard programming interfaces, making it suitable for embedded control and interface tasks in industrial environments.

Key Features

• Logic Capacity — 256 logic elements and 32 logic blocks provide compact programmable logic ideal for glue logic, control sequencing and small state machines.
• I/O — 21 general-purpose I/Os offered in a small-package footprint to support peripheral interfacing and signal aggregation.
• Package — 32‑UFQFN exposed pad (5×5 mm) package provides a compact, thermally aided footprint for space-constrained board designs.
• Voltage Range — Single-supply operation from 2.375 V to 3.465 V to accommodate a range of system power rails.
• Industrial Temperature Range — Rated for −40 °C to 100 °C operation to meet demanding environmental requirements.
• Family-Level System Features — As part of the MachXO2 family, benefits include instant-on non-volatile configuration, support for JTAG/SPI/I²C programming interfaces, and system-level functions such as on-chip timers and SPI/I²C controllers (family capability).
• Compliance — RoHS-compliant device to support regulatory requirements for lead-free assemblies.

Typical Applications

• Industrial Control — Compact control logic and interface bridging in industrial equipment where the −40 °C to 100 °C rating and exposed‑pad QFN package aid thermal management.
• Board-Level Glue Logic — Replaces discrete logic for address decoding, bus arbitration and simple state machines using the device’s 256 logic elements and 21 I/Os.
• Human-Machine Interfaces — Manage buttons, LEDs and simple display drive circuits with on-chip programmable logic and multiple general-purpose I/Os.
• Embedded System Integration — Implement custom peripherals, protocol converters or control sequencers in compact embedded systems with limited board space and a single supply rail.

Unique Advantages

• Small-footprint programmable logic: 256 logic elements in a 5×5 mm QFN package lets designers add programmable functionality without increasing board area.
• Industrial robustness: Rated from −40 °C to 100 °C and offered in an exposed‑pad QFN for improved thermal dissipation, supporting reliable operation in challenging environments.
• Flexible power interfaces: Wide supply range (2.375 V–3.465 V) simplifies integration with common 2.5 V and 3.3 V system rails.
• Part of an expandable family: MachXO2 family support enables density migration and access to shared design flows and system-level features across higher-density members.
• RoHS compliant: Meets lead-free assembly requirements for modern manufacturing processes.
• Standard programming interfaces: Family support for JTAG, SPI and I²C programming simplifies in-system programming and production workflows.
