LCMXO3L-640E-5MG121C

The LCMXO3L-640E-5MG121C is a MachXO3 family FPGA in a 121-VFBGA (6×6) CSPBGA package designed for surface-mount integration. It provides 640 logic elements, 65,536 bits of on-chip RAM, and 100 I/Os in a commercial-grade device targeted at embedded control, interface bridging, and system glue logic.

Built on the MachXO3 architecture, the device combines non-volatile, multi-time programmable configuration with embedded peripherals and on-chip memory to simplify system design and reduce external component count.

Key Features

• Core Logic  640 logic elements suitable for small to mid-range control and glue logic functions.
• Embedded Memory  65,536 bits of on-chip RAM (approximately 64 kbits) for FIFOs, small buffers, and state storage.
• I/O Resources  100 general-purpose I/Os provided in programmable I/O cells for flexible interfacing to peripherals and buses.
• Non‑volatile Configuration  MachXO3 family supports non-volatile, multi-time programmable configuration and TransFR reconfiguration capabilities.
• Integrated System IP  Family-level embedded hardened IP functions include I²C and SPI cores, timers/counters and user flash memory (UFM), reducing external logic requirements.
• Clocking and Timing  On-chip oscillator and system PLLs (sysCLOCK) documented in the family datasheet for flexible clock management.
• Power and Modes  Standby mode and power-saving options are available as part of the MachXO3 family feature set.
• Package & Supply  121-VFBGA, CSPBGA (supplier package: 121-CSFBGA, 6×6) in a surface-mount format; nominal supply range 1.14 V to 1.26 V.
• Operating Range & Compliance  Commercial grade operation from 0 °C to 85 °C; RoHS compliant.
• System & Test  Family includes features for configuration and testing such as IEEE 1149.1-compliant boundary-scan support and configuration/testing infrastructure.

Typical Applications

• Interface Bridging  Use the 100 I/Os and programmable I/O cells to implement bus bridging, level translation control, or peripheral aggregation without extensive external logic.
• Embedded Control  Leverage 640 logic elements and on-chip RAM for state machines, control logic, and local sequencing in consumer and industrial equipment (commercial-grade temperature range).
• Glue Logic & System Integration  Replace discrete glue components by consolidating miscellaneous control, reset sequencing, and timing functions into a single programmable device.
• Peripheral Offload  Hardened I²C/SPI IP cores and timers enable offloading of common peripheral control tasks from a main processor.

Unique Advantages

• Compact, high‑density integration: 640 logic elements and 65,536 bits of embedded RAM in a 121-VFBGA (6×6) package reduce board footprint and BOM complexity.
• Non-volatile, reprogrammable configuration: Multi-time programmable, non-volatile configuration removes the need for an external configuration memory while enabling in-field updates.
• Built-in system IP: Hardened I²C and SPI cores, timers, and UFM lower software and hardware integration effort by providing ready-to-use blocks.
• Flexible clocking and I/O: On-chip oscillator and PLL support combined with programmable I/O cells enable adaptable timing architectures and interfacing options.
• Designed for manufacturability: Surface-mount 121-VFBGA (6×6) package and RoHS compliance simplify assembly and regulatory handling for commercial products.
• Test and debug support: Family-level support for boundary-scan and configuration/debug features assists manufacturing test and field diagnostics.
