LCMXO2-640ZE-3TG100I

The LCMXO2-640ZE-3TG100I is a MachXO2 series FPGA device providing reconfigurable logic in a compact 100-pin LQFP/TQFP package. It delivers 640 logic elements, 18,432 bits of on-chip RAM and 78 I/Os in a surface-mount industrial-grade package for embedded control, glue-logic and system interface tasks.

Designed for low-power, instant-on system designs, this MachXO2 device targets industrial and general embedded applications that require flexible I/O, non-volatile configuration and a small-footprint FPGA with extended temperature operation.

Key Features

• Core Logic  640 logic elements provide flexible reprogrammable logic for glue logic, protocol bridging and control functions.
• Memory  18,432 total RAM bits of embedded memory for small FIFOs, state machines and buffering needs.
• I/O  78 available I/Os in the 100-pin package support diverse interfacing and board-level connectivity.
• Non-volatile Configuration  MachXO2 family features on-chip user flash memory and instant-on reconfiguration options for single-chip, secure solutions (family-level capability).
• Low Power  Family-level MachXO2 architecture supports ultra-low standby power options (datasheet cites very low standby operation for the family).
• Clocking and Timing  Family architecture provides multiple primary clocks and on-chip PLL options (as specified for MachXO2 family devices).
• Package and Mounting  Surface-mount 100-pin LQFP/TQFP (14 mm × 14 mm) package suitable for compact PCB layouts.
• Voltage and Temperature  Supported supply range 1.14 V to 1.26 V and industrial operating temperature from -40°C to 100°C.
• Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Use as system glue logic, sensor interface and real-time control where extended temperature range and industrial grade are required.
• Interface Bridging  Implement protocol conversion, I/O expansion and timing adaptation between discrete subsystems using the device's flexible I/O and logic resources.
• Embedded System Glue  Replace multiple discrete parts for board-level control, reset logic, and peripheral management with a single reconfigurable device.
• Low-Power, Always-On Logic  Deploy in designs that need minimal standby power and instant-on reconfiguration for background programming and secure boot options.

Unique Advantages

• Compact, Reconfigurable Logic: 640 logic elements in a 100-pin package reduce board space and consolidate glue logic.
• On-Chip Embedded Memory: 18,432 bits of RAM enable local buffering and small FIFO implementations without external SRAM.
• Industrial Operating Range: Rated for -40°C to 100°C operation to meet extended-temperature deployment needs.
• Flexible I/O Count: 78 I/Os provide broad interfacing options for mixed-signal and digital peripherals.
• Low-Voltage Single-Supply: Narrow supply range (1.14 V to 1.26 V) simplifies power supply design where this voltage domain is used.
• RoHS Compliant: Meets common lead-free manufacturing requirements.
