Macronix MX25Ux/MX66Ux 1.8V CMOS OctaBus™ NOR Flash

Macronix MX25UM, MX25UW, MX66UM, and MX66UW 1.8V CMOS OctaBus™ NOR Flash are extreme speed memory products built on a Serial Peripheral Interface (SPI) and command protocol, providing extendable I/O capability. These components incorporate flash and RAM into the same data I/O bus, reducing the pin count to twelve. These NOR Flash devices are an ideal solution for Over-the-Air (OTA) update applications, which are becoming more prevalent within automotive cockpit solutions.

The MX25UM, MX25UW, MX66UM, and MX66UW components feature a multiple bank architecture solution based on an ultra-high-performance OctaBus interface. The UW series provides simultaneous Read-While-Write capability, allowing read access from one memory bank while writing to another. The UM series features a fast 250MHz frequency and a Data Transfer Rate (DTR) feature.

Features

  • Single I/O and Octa I/O protocol support
  • Supports DTR (Double Transfer Rate) mode
  • Supports clock frequencies up to 133MHz
  • 1.65V to 2V single power supply operation for read, erase, and program
  • Equal sectors with 4K bytes each or equal blocks with 64K bytes each, any block can be erased individually
  • 24-ball BGA (5mm x 5mm ball array), 16-pin SOP, 49-ball WLCSP, or 68-Ball WLCSP package options
  • Halogen-free and RoHS-compliant
