High-Performance, Multi-I/O, RPMC SPI NOR FLASH PC BIOS Micron SPI NOR Flash for PC BIOS ® Finding a serial peripheral interface (SPI) NOR Flash solution that’s right for your PC BIOS application is easy when you have access to one of the industry’s broadest SPI NOR product portfolios. Our SPI NOR product line is tailored to meet PC BIOS application requirements, including replay-protected monotonic counter (RPMC)-based security needs. Your design will benefit from dramatic read performance, flexible memory partitioning, small package sizes, and a range of density and packaging options. Meet Security Requirements RPMC significantly enhances preboot security in cost-sensitive embedded, mobile, and personal computing architectures. Our RPMC-enabled device facilitates critical nonvolatile data storage while making systems resistant to rollback and replay attacks. It enables designers to strengthen code/data storage in the boot memory and deliver increased security. SPI NOR Solutions – N25Q • Single, dual, quad SPI I/O •16Mb–1Gb • 1.8V or 3V • 108 MHz sync reads (54 MB/s) • DFN, SOP, PBGA packages Contact Us Visit micron.com for more details on SPI NOR Flash solutions. 4 Reasons Why Micron SPI NOR Flash Is Right for Your PC BIOS Design 1. Broad Portfolio Get a flexible, efficient board design when you choose from a wide range of densities and reduced ball count package options. 2. High Read Throughput Achieve faster boot-up with quad I/O and 54 MB/s read speeds. 3. Flexible Memory Partitioning Manage data with greater efficiency with uniform 4KB and 64KB subsector erase. 4.
