MT25QL128ABB8ESF-0AUT

MT25QL128ABB8ESF-0AUT is Macronix’s 128‑Mbit serial NOR flash memory with Quad SPI interface. It’s used to store firmware or data in embedded systems and can be accessed via standard SPI or Quad I/O modes for higher throughput.
Key points:
- Capacity: 128 Mbit (16 MB)
- Interface: Quad SPI (supports single/dual/quad I/O reads)
- Features: 256‑byte page program, sector/block erase, write protection options, deep power‑down and resume
- Package: 8‑pin package (typical for this part)
- Variants: available in different supply voltages and temperature ranges (commercial and automotive variants exist)
Note: exact electrical specs (voltage, clock speed, endurance, temperature range) depend on the specific variant. For precise numbers, consult the MT25QL128ABB8ESF-0AUT datasheet or Macronix product page.

Common cross-refs for a 128-Mbit Quad-SPI flash (same density/interface):
- Winbond: W25Q128FV/JV
- Macronix: MX25L12845G (MX25L12845GUI); MX25U12845G
- Gigadevice: GD25Q128C/D
- Cypress/Spansion: S25FL128S
- Puya: P25Q128H
Note: verify voltage (1.8V vs 3.3V), temperature range, and package/pinout for exact compatibility.
