GD25LB512ME3IRR

Memory IC Overview

The GD25LB512ME is a 512M-bit (64M-Byte) Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard SPI, Quad SPI, DTR Quad I/O, and QPI interfaces with a maximum clock frequency of 166 MHz. The device operates on a single power supply voltage ranging from 1.65V to 2.0V. Key electrical characteristics include a typical standby current of 20μA and a typical power-down current of 4μA. Data transfer rates reach up to 720 Mbits/s in DTR mode. The memory organization consists of uniform sectors of 4K Bytes and blocks of 32K or 64K Bytes.

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type (SOP16, WSON8, TFBGA24, or WLCSP). Confirm the voltage range requirement aligns with the 1.65V–2.0V specification. Ensure design compatibility with the 166 MHz maximum clock frequency and DTR interface support if high-speed performance is critical.

Memory IC Selection Notes

Select this component for designs requiring 512M-bit density within a low-voltage 1.65V–2.0V domain. Consider the available package options including SOP16, WSON8, TFBGA24, and WLCSP based on board space constraints. Evaluate interface needs against Standard SPI, Quad SPI, or DTR capabilities to optimize data throughput.

Memory IC Part Context

The GD25LB512ME belongs to the GD25LB series of low-voltage Serial NOR Flash memories. This series is designed for applications demanding high performance and low power consumption. It complements GigaDevice's broader portfolio of SPI NOR Flash products that support various voltage levels and densities.

Memory IC Replacement Considerations

Check datasheet compatibility for pinout and command set equivalence. Verify voltage range alignment (1.65V–2.0V). Confirm interface support (SPI, QPI, DTR) and timing parameters match system requirements before substitution.

Memory IC FAQ

What is the default state of the device after power-up?

Upon power-up, the device defaults to Standard/Quad SPI mode. All volatile bits return to their default status as defined in the datasheet.

How does the hardware write protection function work?

Hardware write protection is controlled by the WP# pin. When WP# is driven low, it protects the Block Protect (BP) bits and the Status Register Protection (SRP0) bit from being modified.

What is the purpose of the RESET# pin?

The RESET# pin is a dedicated hardware reset input. Driving it low for a minimum period resets the device to standby mode and clears all volatile status bits, regardless of the current operation state.
