Overview

The LCMXO3LF-4300C-5BG400C is a member of the MachXO3LF family, a non-volatile FPGA designed for bridging and I/O expansion. It features 4320 logic elements and integrated flash memory, allowing for instant-on capability and high-density integration in a 400-ball caBGA package. This part operates on a 2.375V to 3.465V supply and provides a high I/O count of 335 pins for complex system management tasks.

Why Choose This Part

The MachXO3LF series offers ultra-low power consumption with a standby current as low as 10uA and a run current of approximately 12.87mA. Its integrated 448KB flash memory eliminates the need for external boot PROMs, reducing both BOM cost and PCB footprint. With 335 I/O pins in a 17x17mm package, it provides an exceptional ratio of connectivity to physical size.

Applications

System Control and Power Sequencing
Managing power-up/down sequences and glue logic for complex PCBs with multiple processors and peripherals.
I/O Expansion
Providing additional GPIO, I2C, or SPI ports to host microprocessors that have limited native pin counts.
Sensor Hub Interface
Aggregating multiple low-speed sensor inputs into a single high-speed interface for a central SoC.
Video Bridging
Implementing interface conversion logic for small displays or camera modules in embedded systems.
