MT25TL512HBA8ESF-0AAT

MT25TL512HBA8ESF-0AAT is a serial non-volatile memory device (flash) in Micron’s MT25TL family. It provides 512‑Mbit of storage in an 8‑pin package and is designed for embedded applications to store firmware and data.
Key points:
- Interface: Serial NOR flash with Quad SPI (high-speed read) and standard SPI modes.
- Density: 512 Mbit; supports typical page-program (256 bytes) and block/sector erase.
- Features: Deep Power-Down, fast read modes, and sector/block protection with status/configuration registers; security options available.
- Variants: Part naming (HBA8ESF-0AAT) reflects temperature/grade, packaging, and voltage variants (some MT25TL parts support 1.8V and/or higher-voltage operation).
- Use: Connect to a microcontroller/CPU via SPI; issue standard flash commands for read/write/erase and use status bits to poll readiness.
- Documentation: Refer to the MT25TL512HBA8ESF-0AAT datasheet and product brief from Micron for exact electrical characteristics, timing, command set, and protection options.
