MX25L2026EM1I-12G

MX25L2026EM1I-12G is Macronix’s 2-Mbit SPI Serial Flash memory. It provides inexpensive, non-volatile storage for firmware, configuration data, or small data logs in embedded systems, accessible over an SPI interface.
Key points
- Capacity: 2 Mbit (256 KB)
- Interface: SPI with options for Dual/Quad I/O for higher throughput
- Voltage: typically 2.7–3.6 V (single-supply variant)
- Speed: up to high-speed clocking (product variant supports fast SPI/Quad modes; exact max depends on voltage/temperature)
- Operations: read, page program (typically 256-byte pages), sector/block/chip erase, write enable/disable, and usual protection/status registers
- Package/variant: EM1I-12G denotes the specific packaging and speed grade
- Applications: boot firmware storage, code/data storage for MCUs, small configuration stores
Note: exact timing, address width (3-byte vs 4-byte), sector sizes, and pinout depend on the specific datasheet revision. Consult the MX25L2026EM1I-12G datasheet for precise specs and to confirm the features you need.
