LCMXO2-640HC-5SG48I

The LCMXO2-640HC-5SG48I is a MachXO2 family FPGA from Lattice Semiconductor Corporation delivering 640 logic elements and approximately 18.4 kbits of on-chip RAM in a compact 48‑VFQFN (7 × 7 mm) exposed pad package. Designed for embedded control and interface tasks, it combines a flexible logic architecture with low-power operation and non-volatile reconfiguration capabilities.

This device targets industrial applications that require a small-footprint, surface-mount FPGA with 40 programmable I/Os, a single power supply range of 2.375 V to 3.465 V, and an extended operating temperature range from −40 °C to 100 °C.

Key Features

• Core Logic — 640 logic elements suitable for glue logic, control functions, and small to mid-density programmable logic tasks.
• On‑Chip Memory — Total on-chip RAM of 18,432 bits, providing distributed and block memory for FIFOs, small buffers, and control state.
• I/O — 40 programmable I/Os with the MachXO2 family’s flexible sysIO buffer support for a wide range of signaling options and on‑chip differential termination.
• Power — Single-supply operation from 2.375 V to 3.465 V and family-level ultra-low-power design options including standby modes and power-saving features.
• Reconfiguration & Non‑Volatility — MachXO2 family supports instant-on non-volatile configuration and in-field reconfiguration capabilities.
• Peripherals & System Functions — Family-level hardened functions including SPI, I2C and timer/counter primitives, plus an on-chip oscillator and unique device identification features.
• Package & Mounting — 48‑VFQFN exposed pad (48‑QFN, 7 × 7 mm) for surface-mount PCB assembly and thermal conduction.
• Industrial Temperature Grade — Rated for operation from −40 °C to 100 °C.
• Compliance — RoHS compliant.

Typical Applications

• Display and Video Interfaces — Use the family’s source-synchronous I/O and gearing features for driving or bridging display interfaces.
• System Glue Logic — Implement bus bridging, protocol adaptation and glue logic between discrete controllers and peripherals using the 640 logic elements and flexible I/O.
• Peripheral Control and Sensor Interfaces — Leverage on-chip SPI/I2C support and programmable I/Os for sensor aggregation, status monitoring, and control modules.
• Low‑Power Embedded Functions — Deploy in battery-conscious or standby-heavy systems that benefit from the family’s low-power modes and instant-on capability.

Unique Advantages

• Compact, Surface-Mount Footprint: The 48‑VFQFN exposed pad package (7 × 7 mm) minimizes PCB area while providing thermal relief and routing convenience.
• Industrial Temperature Range: Rated from −40 °C to 100 °C, suitable for industrial environments that require extended temperature operation.
• Flexible I/O and Interface Support: MachXO2 family sysIO buffering and differential termination enable a broad set of interface options without external components.
• Non‑Volatile, Instant‑On Operation: Built-in non-volatile configuration allows rapid start-up and field updates without external configuration devices.
• Single-Supply Simplicity: Wide supply range (2.375 V to 3.465 V) simplifies power rail design across a variety of systems.
• RoHS Compliance: Meets environmental regulations for lead-free manufacturing processes.
