- Features: Write protection, hardware protection, deep power-down, resume
- Temperature/grade: industrial/extended options available; verify exact grade in datasheet
Note: For exact electrical specs, timing, packaging, and temperature range of your exact die/lot, consult the MX25L512EZUI-10G datasheet.

8-pin SOP (SOIC) package, Pb-free.

- Pin count: 8 pins (8-pin package).
- Function: 512-Mbit SPI/NOR flash memory for non-volatile storage. Uses a four‑wire SPI interface (SCK, SI/DI, SO/DO) plus CS, WP#, HOLD#, Vcc, and GND. Used to store firmware/data with commands for read/fast-read, page program, sector/block erase, and chip erase.

- Manufacturer: Macronix International Co., Ltd. (MXIC)
- What kind of company: A Taiwan-based semiconductor company and integrated device manufacturer (IDM) that designs and manufactures non-volatile memory products (NOR/NAND flash) and related ICs using its own fabrication facilities.

- Boot memory and firmware storage for MCUs/SoCs
- FPGA/PLD configuration bitstreams
- Secure firmware updates and code storage
- OS images, applications, and parameter/data logging in embedded devices
- Used in consumer electronics (routers, gateways, set-top boxes, cameras) and automotive/industrial non-volatile storage
