LCMXO3LF-4300C-5BG400I

The LCMXO3LF-4300C-5BG400I is a MachXO3 family FPGA device in a 400-LFBGA (400-CABGA, 17×17) package, offered in an industrial grade configuration. It provides 4,320 logic elements, approximately 94,208 bits of on-chip RAM, and 335 I/O pins, delivering a flexible, non-volatile FPGA building block for embedded system control, interface bridging, and programmable I/O applications.

Designed for surface-mount applications, this device supports a supply voltage range of 2.375 V to 3.465 V and an operating temperature range of –40 °C to 100 °C, making it suitable for industrial temperature environments while providing integrated clocking, memory, and hardened IP functionality as described in the MachXO3 family documentation.

Key Features

• Logic Capacity — 4,320 logic elements (logic cells) for implementing glue logic, control state machines, and moderate-density programmable logic functions.
• Embedded Memory — Total RAM: 94,208 bits of on-chip memory (sysMEM block RAM) for small FIFOs, buffering and local data storage.
• High Pin Count I/O — 335 I/O pins to support multiple interfaces and parallel/serial connectivity in a single device package.
• Non-volatile, Multi-time Programmable Configuration — MachXO3 family capability for non-volatile configuration and in-field reprogramming (as documented in the MachXO3 family data sheet).
• Embedded Hardened IP — Family-level documentation lists hardened IP including I2C, SPI and timer/counter blocks that simplify common peripheral integration.
• Flexible Clocking — On-chip clocking resources such as PLLs (sysCLOCK) to support diverse timing and clock-domain requirements.
• Package & Mounting — 400-LFBGA (supplier device package 400-CABGA, 17×17) in a surface-mount form factor for compact board integration.
• Industrial Temperature Grade — Rated for operation from –40 °C to 100 °C to meet industrial-environment requirements.
• Voltage Range — Operates from 2.375 V to 3.465 V, enabling use with common board power rails.
• RoHS Compliant — Device conforms to RoHS requirements.

Typical Applications

• Sensor and Peripheral Interfaces — Use the device’s hardened I2C and SPI IP blocks and multiple I/Os for robust sensor interfacing and peripheral control.
• Protocol Bridging and I/O Expansion — High I/O count and programmable I/O cells support protocol translation, bus bridging, and expansion of microcontroller I/O without major PCB redesign.
• Embedded System Control — On-chip clocking, timers/counters and logic elements enable implementation of control state machines and timing-critical functions.
• Configuration and Local Storage — Non-volatile configuration and on-chip RAM (sysMEM) support local storage of configuration data, small FIFOs, and buffering needs.

Unique Advantages

• Highly Integrated Functionality: Combines logic elements, embedded RAM, PLL-based clocking and hardened IP to reduce external components and BOM complexity.
• Industrial-ready Thermal Range: Specified operation from –40 °C to 100 °C for deployments in industrial temperature environments.
• Wide Supply Voltage Window: 2.375 V to 3.465 V operation accommodates common board power architectures and eases integration.
• Large I/O Availability: 335 I/O pins enable multiple interfaces and parallel connectivity without additional multiplexers or bridges.
• Non-volatile, Reprogrammable: Multi-time programmable non-volatile configuration enables field updates and design iteration without external configuration devices.
• Compact, Surface-Mount Package: 400-LFBGA (17×17) provides a high-pin-count solution in a compact footprint for space-constrained designs.
