GD25LB512MEYIGR – Serial NOR Flash – GigaDevice

The GigaDevice GD25LB512MEYIGR is a 512 Mbit, 1.8V automotive-grade Serial NOR Flash memory in a WSON-8 (8x6mm) package, supporting Quad I/O, QPI and DTR operation up to 133 MHz. AEC-Q100 qualified and available now for RFQ.

The GD25LB512MEYIGR from GigaDevice is a high-density 512 Mbit (512 Mb) Serial NOR Flash memory belonging to the automotive-grade GD25LB512ME family. Operating from a low 1.65V to 2.0V supply, it is optimized for 1.8V systems and delivers fast, reliable code-shadow and data storage for space-constrained, power-sensitive designs. The device is packaged in an 8-pin WSON (8x6mm) and is AEC-Q100 qualified for automotive applications.

This part supports a flexible serial interface set including Standard (Single) SPI, Quad I/O, QPI and Double Transfer Rate (DTR) operation, with a maximum clock frequency of 133 MHz in single and quad modes and 90 MHz in quad DTR mode for high-throughput instruction fetch and execute-in-place (XIP) use cases.
