MX25L25735FZ2I-10G

MX25L25735FZ2I-10G is Macronix’s 256-Mbit serial NOR flash memory. It is designed for embedded code storage and firmware updates, offering fast SPI-based access with Quad I/O options for higher throughput.
Key points
- Density and interface: 256 Mbit (32 MBytes); SPI-compatible with Quad I/O support for higher data rates.
- Addressing: 4-byte addressing to access the full capacity.
- Operations: page program (typically 256 bytes), sector erase (e.g., 4 KB), block erases (e.g., 64 KB/256 KB), and full-chip erase; supports fast read and standard read modes.
- Features: low-power modes, power-down, hold, and hardware protection/security features (e.g., write protection and protection registers), with suspend/resume during erase/program.
- Voltage and package: operates from a nominal 2.7–3.6 V supply; available in small 8-pin packages suitable for compact boards; “-10G” denotes a specific temperature/packaging variant.
- Applications: boot memory, firmware storage/updater, data logging in embedded systems.
For exact electrical timings, voltage ranges, package options, and security features, refer to the official datasheet.
