LCMXO2-640HC-4SG48I

The LCMXO2-640HC-4SG48I is a MachXO2 field programmable gate array (FPGA) IC from Lattice Semiconductor, offered in a 48‑lead VFQFN with exposed pad (7 mm × 7 mm). This industrial‑grade device provides a compact, non-volatile FPGA solution with 640 logic elements, on‑chip RAM, and 40 general I/Os for board‑level control, glue logic, and I/O interfacing.

Designed for low‑power and flexible system integration, the MachXO2 family offers features such as instant‑on non‑volatile configuration, programmable I/O options and on‑chip memory, enabling robust control and interface functions across a broad range of embedded applications.

Key Features

• Logic Capacity – Contains 640 logic elements suitable for glue logic, control functions and small state machines.
• On‑chip Memory – 18,432 bits of total RAM (approximately 18 kbits) for distributed memory and buffering.
• I/Os and Interfaces – 40 I/O pins support versatile interfacing for sensors, peripherals and board‑level signals.
• Supply and Power – Single supply operation across a wide range: 2.375 V to 3.465 V, enabling compatibility with common system voltages.
• Industrial Temperature Rating – Operating range from −40 °C to 100 °C for reliable performance in industrial environments.
• Package and Mounting – 48‑VFQFN exposed pad (48‑QFN, 7×7 mm) surface‑mount package for compact PCB integration and thermal performance.
• RoHS Compliant – Device is RoHS compliant.
• MachXO2 Family Capabilities – Family features include ultra low power operation, on‑chip user flash memory, programmable I/O buffer options, flexible clocking and in‑field reconfiguration (as documented in the MachXO2 family data sheet).

Typical Applications

• Board‑level glue logic – Use the 640 logic elements and 40 I/Os to implement address/data multiplexing, protocol bridging and custom control logic that reduce external components.
• System control and monitoring – On‑chip RAM and non‑volatile configuration support control tasks, state machines and system supervisory functions in industrial systems.
• Peripheral and sensor interfacing – Flexible I/O and single‑supply operation make the device suitable for interfacing mixed voltage peripherals and sensors.
• Display and synchronous I/O support – Leverage MachXO2 family I/O features for source‑synchronous or display gearing applications as required by the system design.

Unique Advantages

• Compact, thermally capable package – The 48‑VFQFN (7×7 mm) with exposed pad enables small footprint designs while supporting thermal dissipation and surface‑mount assembly.
• Wide supply range – Operation from 2.375 V to 3.465 V simplifies integration with common 2.5 V and 3.3 V systems without additional regulators.
• Industrial temperature support – Specified for −40 °C to 100 °C to meet the needs of industrial control and instrumentation environments.
• On‑chip RAM for local buffering – 18,432 bits of embedded RAM provide space for lookup tables, FIFOs and small buffers directly inside the FPGA fabric.
• Non‑volatile family architecture – MachXO2 family characteristics include instant‑on configuration and on‑chip user flash memory options for persistent configuration and secure boot strategies.
