LCMXO3L-4300C-5BG400C

The LCMXO3L-4300C-5BG400C from Lattice Semiconductor Corporation is a MachXO3 family FPGA in a 400-LFBGA (400-CABGA, 17×17) package. It provides a compact, non-volatile programmable logic solution with a focused set of on-chip memory, I/O, and embedded peripherals suitable for commercial-grade designs.

This device integrates approximately 4,320 logic elements, about 94,208 bits of embedded RAM, and up to 335 I/O pins, enabling moderate-density control, glue-logic, and system-integration tasks where a surface-mount, RoHS-compliant FPGA is required.

Key Features

• Core Logic – Approximately 4,320 logic elements for implementing custom logic, finite-state machines, and glue logic in a single device.
• On-chip Memory – Approximately 94,208 bits of embedded RAM that support single-, dual- and pseudo-dual-port configurations and FIFO modes as described in the MachXO3 family architecture.
• High I/O Density – Up to 335 programmable I/O pins for broad interfacing flexibility across multiple buses and peripherals.
• Packaging & Mounting – 400-LFBGA (supplier package: 400-CABGA, 17×17) surface-mount package optimized for high-density board layouts.
• Voltage & Temperature – Supported supply range from 2.375 V to 3.465 V and commercial operating temperature from 0 °C to 85 °C.
• Non-volatile, Multi-time Programmable – MachXO3 family architecture includes non-volatile configuration and multi-time programmability for in-field updates and configuration retention.
• Flexible Clocking & PLLs – Family-level clocking architecture includes on-chip PLLs and flexible clock distribution to support a variety of timing requirements.
• Embedded Hardened IP – MachXO3 family includes hardened functions such as I²C, SPI, and timer/counter blocks to reduce logic overhead for common system tasks.
• Pre-engineered I/O and Reconfiguration – Pre-engineered source-synchronous I/O, flexible I/O buffer options, and TransFR reconfiguration capabilities are part of the MachXO3 feature set.
• Standards & Compliance – RoHS compliant; commercial-grade device suitable for general embedded and consumer applications.

Unique Advantages

• High integration in a compact package: Combines thousands of logic elements, embedded RAM, and up to 335 I/Os in a 400-LFBGA to reduce board area and BOM count.
• Non-volatile configuration: Multi-time programmable, non-volatile configuration simplifies system initialization and field updates without external configuration memory.
• Flexible I/O and clock resources: Pre-engineered source-synchronous I/O and on-chip PLLs simplify timing closure and interface implementation.
• Embedded peripheral IP: Hardened I²C, SPI, and timer/counter blocks free up logic resources for application-specific functions.
• Commercial-grade operating range: Designed for 0 °C to 85 °C operation and a wide supply range (2.375 V–3.465 V) to match common commercial system requirements.
• RoHS compliant: Meets environmental compliance needs for modern electronics manufacturing.
