LCMXO3L-4300E-5UWG81ITR

The LCMXO3L-4300E-5UWG81ITR is a MachXO3 family Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It provides a compact, surface-mount FPGA implementation in an 81-WLCSP package designed for industrial-grade applications.

With 4,320 logic elements, approximately 0.094 Mbits (94,208 bits) of embedded RAM and 63 I/Os, this device targets system control, I/O interfacing and configuration tasks where non-volatile, reprogrammable logic and flexible I/O are required. Key value lies in integrated memory, reconfiguration capabilities and tailored on-chip resources exposed by the MachXO3 family architecture.

Key Features

• Logic and Configurable Resources — 4,320 logic elements and 540 logic blocks provide compact programmable logic capacity for glue-logic, control and simple state machines.
• Embedded Memory — Approximately 0.094 Mbits (94,208 bits) of on-chip RAM for small FIFOs, buffers or lookup tables.
• I/O and Package — 63 user I/Os in an 81-WLCSP (3.80×3.69 mm) package; surface-mount mounting for tight BOM and small form-factor designs.
• Voltage and Temperature — Operates from 1.14 V to 1.26 V and specified for an industrial temperature range of −40 °C to 100 °C.
• Non-volatile, Multi-time Programmable — MachXO3 family features include non-volatile configuration and multi-time programmability for field updates and configuration retention.
• Integrated Peripherals and IP — Datasheet highlights embedded hardened IP such as I²C and SPI cores, timer/counter, on-chip oscillator and user flash memory (UFM) for common control and interface functions.
• Flexible Clocking and Reconfiguration — Family-level features include PLLs and TransFR reconfiguration to support versatile clocking and in-field reconfiguration workflows.
• RoHS Compliant — Device is RoHS compliant for environmental and manufacturing compliance.

Typical Applications

• System Control and Glue Logic — Implement control state machines, interconnect logic and protocol adaptation in compact industrial systems.
• I/O Expansion and Interface Bridging — Use the flexible I/O and embedded IP to bridge peripherals, manage sensor interfaces or aggregate signals for higher-level controllers.
• Configuration and Boot Management — Non-volatile, reprogrammable configuration makes the device suitable for configuration management, boot sequencing and small-scale security or initialization tasks.

Unique Advantages

• Compact, production-friendly package: 81-WLCSP (3.80×3.69 mm) and surface-mount mounting reduce PCB area and simplify integration into dense assemblies.
• Industrial temperature range: Specified operation from −40 °C to 100 °C supports deployment in thermally demanding environments.
• Non-volatile reprogrammability: Multi-time programmable configuration enables in-field updates and simplifies inventory by allowing firmware revisions without hardware changes.
• Integrated IP and peripherals: Hardened I²C/SPI cores, timer/counter, on-chip oscillator and UFM reduce external component count and shorten development time.
• Right-sized resources: 4,320 logic elements and ~0.094 Mbits of RAM balance capability and cost for control, interface and glue-logic roles.
