LCMXO2-640HC-6TG100I

The LCMXO2-640HC-6TG100I is a MachXO2 family field programmable gate array (FPGA) in a 100-pin LQFP (14 × 14 mm) package. It provides 640 logic elements, approximately 18 kbits of embedded RAM, and 78 I/Os in a low-power, instant-on, non-volatile FPGA architecture.

Designed for industrial-grade applications, this device combines flexible, reconfigurable logic with on-chip flash memory, system-level peripherals and programmable I/O to simplify control, interface and glue-logic tasks in embedded systems.

Key Features

• Core Logic 640 logic elements enable small to medium density glue logic, control and interface functions within a single-chip FPGA.
• Embedded Memory Approximately 18 kbits of total RAM bits (embedded block RAM and distributed RAM) for FIFOs, small buffers and configuration storage.
• On-Chip Non-Volatile Flash Family support for on-chip user flash memory (UFM) enables single-chip, infinitely reconfigurable designs and background programming.
• Flexible I/O 78 I/Os with a programmable sysIO buffer supporting a wide range of standards, differential termination and hot-socketing options for robust interface design.
• Clocking and PLLs Multiple primary clocks with up to two analog PLLs per device for fractional-n frequency synthesis and flexible clocking in mixed-signal systems.
• Low Power Options MachXO2 family devices include ultra low power modes with very low standby power and programmable power-saving options to reduce system consumption.
• System-Level Functions On-chip hardened peripherals including SPI, I²C and timer/counter functionality reduce external components and simplify firmware integration.
• Industrial Grade and Packaging Surface-mount 100-LQFP (14 × 14 mm) package with an operating temperature range of −40 °C to 100 °C and RoHS-compliant construction for industrial deployments.
• Supply Voltage Supports a single supply range of 2.375 V to 3.465 V to accommodate 2.5 V and 3.3 V system rails.

Typical Applications

• Control and Glue Logic Implement board-level glue logic, bus bridging and peripheral control using compact, reconfigurable logic and on-chip flash for firmware updates.
• User Interfaces Manage display and input interfacing with programmable I/O and embedded memory for buffering and timing.
• Industrial Automation Integrate sensor interfacing, simple motor control logic and communications glue within an industrial-temperature FPGA package.
• System Management Offload system supervisory tasks using on-chip timers, SPI/I²C hardware and non-volatile configuration storage.

Unique Advantages

• Instant-on, Non-volatile Operation: On-chip flash enables immediate startup without external configuration devices, simplifying power-up and system design.
• Reduced BOM and Board Complexity: Hardened SPI, I²C and timer/counter peripherals along with on-chip memory reduce the need for external components.
• Flexible, High-Functionality I/O: Programmable sysIO supports a wide range of signaling standards and differential terminations, allowing versatile interface implementation.
• Industrial Temperature Range: Rated for −40 °C to 100 °C operation to meet demanding environmental requirements in industrial applications.
• Power Efficiency: Family-level low-power modes and configurable power-saving options help minimize standby and runtime power consumption.
