MX25UM51245G 512Mbit Serial NOR Flash
Overview
The MX25UM51245GXDR00-T is a Macronix serial NOR flash memory device with a 1.8 V interface and 512 Mbit capacity. It uses x8 I/O and a BGA-24 package, making it suitable for compact designs that need high-density nonvolatile storage. The automotive grade +105 C rating makes it a fit for demanding embedded systems.
Why Choose This Part
This part combines a relatively large serial NOR capacity with a simple x8 serial interface, which can reduce PCB area and pin count compared with parallel flash. The 1.8 V supply helps match modern low-voltage processors and SoCs. Its automotive temperature rating also makes it more suitable for harsh embedded environments than consumer-grade flash.
Applications
Getting Started
Use it with a host MCU, application processor, or SoC that supports serial NOR flash over SPI or an equivalent memory interface. Confirm the target device supports the required command set, voltage range, and BGA-24 footprint before layout. For firmware bring-up, start with the processor vendor's reference board and bootloader documentation, then verify clocking, read mode, and erase/program timing in your design.
