IC FLASH 256MBIT SPI 133MHZ 8-SOP
Macronix

Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom Board256-megabit serial NOR flash memory supporting single, dual, and quad I/O modes with clock frequencies up to 133MHz. Features SPI protocol compatibility, double transfer rate (DTR) capability, and 3.3V operation. Commonly used for firmware storage, configuration data, and code execution in embedded systems and IoT applications.
This SOIC-8 package is too small to hand-solder reliably and incompatible with breadboards. A breakout board brings 1.27mm pitch pins to standard 0.1-inch spacing, enabling prototyping without specialized equipment. Ideal for memory and sensor ICs that demand convenient development while preserving the compact footprint.
