LCMXO3D-4300HC-5SG72I

The LCMXO3D-4300HC-5SG72I is a MachXO3D family FPGA from Lattice Semiconductor Corporation. This non-volatile, reconfigurable device combines on-chip programmable logic, embedded memory and hardened system IP to support control, interface and security functions in compact board-level designs.

Designed for industrial environments, the device delivers 4,300 logic elements, 58 general-purpose I/Os and a broad supply and temperature range to support embedded control, I/O bridging and system management tasks where integration, configurability and reliability are required.

Key Features

• Programmable Logic — 4,300 logic elements for implementing glue logic, protocol bridges, finite state machines and control functions.
• Embedded Memory — Approximately 0.094 Mbits of on-chip RAM (94,208 bits) for small buffers, FIFOs and state storage.
• I/O Capacity & Flexibility — 58 I/Os with pre‑engineered source-synchronous and flexible I/O buffer support for diverse interface requirements.
• Power and Voltage — Operates from 2.375 V to 3.465 V to match common board power rails.
• Industrial Grade Temperature — Qualified to operate from −40 °C to 100 °C for use in industrial applications.
• Package — 72‑VFQFN exposed pad package (72‑QFN, 10×10 mm) for a compact board footprint and thermal performance.
• Embedded Hardened IP — Includes dedicated blocks such as an Embedded Security Block and hardened peripherals (I2C, SPI, timer/counter) to simplify system integration.
• Clocking & Configuration — Flexible on-chip clocking with PLLs, on-chip oscillator, TransFR reconfiguration and user flash memory (UFM) for system configuration and updates.
• System-Level Support — Features for boundary-scan testability, standby and power-saving modes to assist board-level validation and low-power operation.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement control logic, protocol conversion and I/O handling with the device’s industrial temperature rating and flexible I/O.
• Secure Embedded Systems — Use the Embedded Security Block and hardened peripherals for system authentication, secure boot controllers and protected configuration storage.
• Interface Bridging and Glue Logic — Replace discrete logic for bus bridging, level translation and peripheral aggregation using the programmable logic and on-chip memory.
• Board-Level System Management — Implement reset management, configuration sequencers and monitoring functions leveraging UFM, on-chip oscillator and timers.

Unique Advantages

• Non‑volatile, reconfigurable logic: Enables field updates and persistent functionality without external configuration memory.
• Compact, thermally aware package: 72‑VFQFN with exposed pad offers a small footprint and board-level thermal path for industrial designs.
• Integrated security and hardened IP: Reduces the need for external secure controllers and simplifies implementation of protected functions.
• Wide operating range: 2.375 V–3.465 V supply support and −40 °C to 100 °C operation align with common industrial power rails and ambient conditions.
• Balanced I/O and memory resources: 58 I/Os with built-in memory (≈0.094 Mbits) to support buffering and interface timing without large external RAM.
