LCMXO3LF-4300E-5UWG81ITR1K

The LCMXO3LF-4300E-5UWG81ITR1K is a MachXO3 family field programmable gate array (FPGA) from Lattice Semiconductor. Built for compact, low-voltage embedded designs, this device integrates a mid-density logic fabric with programmable I/O and on-chip memory suitable for system control, interface bridging, and glue-logic tasks.

Key architectural elements include programmable logic with 4,320 logic elements, approximately 0.094 Mbits of embedded memory, flexible on-chip clocking and I/O features drawn from the MachXO3 family, making it a practical choice for industrial-grade applications that require non-volatile configuration and compact packaging.

Key Features

• Core Logic — 4,320 logic elements providing mid-range programmable logic capacity for control, sequencing, and interface functions.
• Embedded Memory — Approximately 0.094 Mbits of on-chip RAM (94,208 bits) for small FIFOs, state machines, and buffering.
• I/O Capability — 63 user I/O pins in a compact package supporting flexible I/O buffering and source-synchronous interfaces as described for the MachXO3 family.
• Non-volatile, Multi-time Programmable Configuration — MachXO3 family configuration supports non-volatile, multi-time programming and TransFR reconfiguration functionality for field updates.
• On-chip Clocking — Flexible on-chip clocking architecture with phase-locked loop (PLL) support and an internal oscillator as documented for the MachXO3 family.
• Embedded Hardened IP — MachXO3 family includes hardened IP building blocks such as I²C and SPI controllers, timers/counters, and other system functions to reduce external components.
• Power and Configuration Features — User Flash Memory (UFM), standby and power-saving modes, and IEEE 1149.1-compliant boundary scan support are included in the MachXO3 family feature set.
• Supply and Mounting — Operates from a nominal supply range of 1.14 V to 1.26 V; surface-mount package suitable for compact PCB assembly.
• Package and Thermal — 81-pin WLCSP / UFBGA package (supplier device package: 81-WLCSP, 3.80 × 3.69 mm) and industrial operating temperature range of −40 °C to 100 °C.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement motor drivers, sequencers, and safety-related control logic using the device’s industrial temperature rating and on-chip logic and memory.
• Interface Bridging and Protocol Conversion — Use the programmable I/O and hardened SPI/I²C IP to implement protocol translators and bridge legacy interfaces to modern systems.
• Embedded System Glue Logic — Replace discrete glue logic and small CPLDs by consolidating control, timing, and buffering functions into the integrated FPGA fabric and on-chip memory.
• Human-Machine Interface (HMI) Control — Drive displays, buttons, and indicator logic while offloading timing and serial peripheral handling to embedded IP blocks.

Unique Advantages

• Non-volatile Configuration: Multi-time programmable, non-volatile configuration reduces external configuration memory and simplifies system start-up.
• Compact WLCSP Footprint: 81-pin WLCSP (3.80 × 3.69 mm) minimizes PCB area for space-constrained designs.
• Industrial Temperature Range: Rated for −40 °C to 100 °C, enabling deployment in industrial environments where extended temperature tolerance is required.
• Low-voltage Operation: Narrow supply range (1.14–1.26 V) supports designs targeting low-voltage digital domains and power-optimized systems.
• Integrated System IP: Hardened I²C, SPI, timers/counters, UFM and other MachXO3 family features reduce BOM and simplify software/firmware integration.
• Flexible Clocking and I/O: On-chip oscillator, PLLs, and pre-engineered source-synchronous I/O options (from MachXO3 family documentation) enable a range of interface timing strategies without added components.
