LCMXO3LF-4300E-5UWG81CTR50

The LCMXO3LF-4300E-5UWG81CTR50 is a MachXO3 family FPGA in an 81-ball WLCSP package designed for compact, low-power programmable logic integration. Built around a flexible FPGA architecture, it offers 4,320 logic elements, on-chip memory, and a rich I/O complement for embedded control, glue logic and interface bridging in space-constrained commercial designs.

This device combines non-volatile multi-time programmability with embedded system features from the MachXO3 family, enabling reconfigurable functions and system-level integration while operating from a low core voltage range of 1.14 V to 1.26 V.

Key Features

• Core Logic  4,320 logic elements for implementing glue logic, state machines and small to mid-density programmable functions.
• Embedded Memory  Approximately 0.094 Mbits (94,208 bits) of on-chip RAM to support FIFOs, small buffers and lookup tables.
• I/O Capability  63 I/O pins to support diverse peripheral interfaces and board-level signal routing in compact designs.
• Package and Mounting  81-ball UFBGA / WLCSP package (81-WLCSP, 3.80 × 3.69 mm) with surface-mount compatibility for dense PCB layouts.
• Power and Temperature  Core supply operating range of 1.14 V to 1.26 V and commercial operating temperature range of 0 °C to 85 °C.
• Non‑volatile, Multi‑time Programmable  MachXO3 family capability for non-volatile configuration and multi-time reprogramming (family-level feature).
• On‑chip System and IP Support  Family features include flexible on-chip clocking (PLLs), an on-chip oscillator, and embedded hardened IP blocks such as I²C, SPI and timer/counter functions (as described in MachXO3 family documentation).
• Standards and Compliance  RoHS compliant; commercial-grade device suitable for general-purpose embedded applications.

Typical Applications

• Embedded Control and Glue Logic  Implement board-level glue logic, protocol conversion and control state machines where small, reprogrammable logic is required.
• Interface Bridging  Bridge between sensors, peripherals and host processors using the device’s I/O density and embedded memory for buffering.
• Compact Consumer and Industrial Electronics  Integrate system logic and peripheral management in space-constrained products leveraging the WLCSP package and surface-mount mounting.

Unique Advantages

• Compact WLCSP Package: Small 81-ball WLCSP (3.80 × 3.69 mm) reduces PCB area and enables dense board integration.
• Low-Voltage Core: Narrow supply range (1.14 V–1.26 V) tailored for low-power system designs.
• Integrated Non‑volatile Configuration: Multi-time programmable configuration reduces the need for external configuration memory in many designs.
• Balanced Logic and Memory: 4,320 logic elements combined with ~0.094 Mbits of embedded RAM supports both control logic and modest on-chip data buffering.
• Commercial Temperature Range: Rated 0 °C to 85 °C for general-purpose applications in consumer and commercial environments.
• RoHS Compliant: Meets lead‑free and hazardous materials requirements for global commercial products.
