- Read/write performance: 45 ns typical access; up to high-speed clock (datasheet specifies max frequency for the chosen mode).
- Memory organization: 256-byte page program; erase blocks of 4 KB, 8 KB, and 64 KB.
- Features: write-enable control, status and configuration registers, block protection, security registers, suspend/resume for erase/program, and deep power-down with wake-up.
- Power and operating range: usually 2.7–3.6 V (check exact variant); temperature ranges per part option.
- Packaging: commonly available in 8-pin packages (e.g., SOP8, WSON8) with the DX suffix indicating package/config.
Typical uses: boot flash, firmware updates, code storage in MCUs/SoCs. For exact timing, voltage, temperature, and package options, refer to the current datasheet for MX25UW51245GXDQ00.
