LCMXO3L-4300E-5UWG81CTR50

The LCMXO3L-4300E-5UWG81CTR50 is a MachXO3 family field-programmable gate array (FPGA) from Lattice Semiconductor Corporation. It integrates approximately 4,320 logic elements, approximately 94 kbits of embedded RAM (94,208 bits), and 63 general-purpose I/Os in an 81-WLCSP package.

Designed for commercial-grade applications, this surface-mount device offers non-volatile, multi-time programmable configuration and family-level features such as flexible on-chip clocking, programmable I/O, hardened peripheral IP, and configurable memory modes—making it suitable for compact system control, I/O bridging, and in-field reconfiguration tasks.

Key Features

• Core Logic  Approximately 4,320 logic elements to implement glue logic, control functions, and small to moderate FPGA designs.
• Embedded Memory  Total RAM bits: 94,208 (approximately 94 kbits) with sysMEM capabilities including single/dual-port and FIFO modes as described in the MachXO3 family documentation.
• I/O and Interface  63 I/O pins with family-level support for pre-engineered source synchronous I/O and flexible I/O buffering for a variety of interface roles.
• Clocking  Flexible on-chip clocking including sysCLOCK PLLs for common clocking and timing requirements (MachXO3 family features).
• On-chip Functions and Hardened IP  Family-level hardened IP options referenced in the datasheet include I2C, SPI, timer/counter, on-chip oscillator and user flash memory (UFM) for configuration and small data storage.
• Configuration and Reconfiguration  Non-volatile, multi-time programmable configuration and TransFR reconfiguration support as part of the MachXO3 family feature set.
• Package and Mounting  81-WLCSP package (supplier device package: 81-WLCSP (3.80x3.69)), surface-mount mounting type, optimized for space-constrained boards.
• Power  Nominal supply voltage range: 1.14 V to 1.26 V, enabling low-voltage system designs aligned with the device’s recommended operating conditions.
• Temperature and Grade  Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Compliance  RoHS compliant for modern manufacturing and environmental requirements.
• Production-Test and System Integration  Family datasheet references IEEE 1149.1-compliant boundary scan testability, hot-socketing support, and TraceID for device traceability and system integration.

Typical Applications

• System Control and Glue Logic  Implement control state machines, protocol adaptation, and peripheral glue logic using the device’s 4,320 logic elements and 63 I/Os.
• I/O Bridging and Interface Adaptation  Use pre-engineered source synchronous I/O and flexible I/O buffering to bridge differing peripheral interfaces and provide timing-aligned data paths.
• Embedded Memory Functions  Leverage approximately 94 kbits of embedded RAM for FIFOs, small buffers, and on-chip data staging in communication or control applications.
• Field-Updatable Logic  Take advantage of non-volatile, multi-time programmable configuration and TransFR reconfiguration for in-field updates and iterative feature development.

Unique Advantages

• Compact, low-profile packaging: The 81-WLCSP footprint provides a small board area solution for space-constrained designs.
• Low-voltage operation: 1.14 V to 1.26 V supply range supports integration into modern low-voltage power rails.
• Integrated memory and I/O: Built-in RAM (94,208 bits) and 63 I/Os reduce external component count for buffering and interfacing tasks.
• Non-volatile configuration: Multi-time programmable, non-volatile configuration removes the need for external configuration memory in many designs.
• Family-level hardened IP: On-chip I2C, SPI, timers, and oscillator options lower BOM and accelerate system integration where these functions are required.
• Commercial-grade readiness: Operates across a 0 °C to 85 °C range and is RoHS compliant for standard commercial product lines.
