概要
Description
M24128-BFMH6TG is a serial nonvolatile memory device (SPI flash) used to store firmware or data in microcontroller systems.
Key points:
- Capacity: typically 128 Kbit (16 KB), byte-addressable.
- Interface: SPI (CS, CLK, MOSI, MISO); often has optional WP and HOLD pins.
- Operations: supports page program, sector erase (commonly 4 KB), and chip erase; status register for busy/write-enable flags.
- Voltage and package: usually 2.7–3.6 V operation; available in 8-pin packages (e.g., SOP-8).
- Endurance/retention: endurance in the range of 100k–1M program/erase cycles; data retention on the order of years to decades.
- Applications: firmware storage, configuration data, small boot memory.
For precise specs (capacity exact, page size, sector size, timing, temperature range, and package type), consult the official datasheet from the manufacturer or distributor. If you share the manufacturer or a link, I can summarize the exact numbers.
