GD25LB16ESIGR

Memory IC Overview

The GD25LB16ESIGR is a 16 Mbit (2M x 8) SPI NOR Flash memory component manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2.1 V and supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 133 MHz. The device features uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. It includes advanced security features such as hardware write protection, OTP security registers, and a unique ID. The part is available in SOP-8 and USON-8 packages.

Memory IC Feature Summary

• Supports Standard, Dual, Quad SPI, and QPI modes for flexible data transfer rates up to 532 Mbits/s.
• Includes software and hardware write protection mechanisms with top/bottom block protection capabilities.
• Features 128-bit Unique ID and three 3x1024-Byte Security Registers with One-Time Programmable locks.
• Enables Execute In Place (XiP) operation with continuous read wrap functionality to reduce latency.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring low power consumption.
• Embedded systems utilizing Execute In Place (XiP) operations.
• Applications requiring secure boot code storage with hardware write protection.
• Consumer electronics and IoT devices needing small form factor memory solutions.

Memory IC Procurement Notes

Verify the specific package variant (SOP-8 or USON-8) matches the design footprint, as the suffix 'GR' indicates reel packaging. Confirm the voltage range requirement aligns with the 1.65V to 2.1V specification. Ensure the host controller supports the required SPI modes (Standard/Dual/Quad) for optimal performance. Check for any specific ordering suffixes that might affect pin compatibility or temperature ratings.

Memory IC Selection Notes

Select this component when a 16 Mbit density is required with a low voltage supply constraint between 1.65 V and 2.1 V. It is suitable for designs prioritizing low standby current and high-speed read access via Quad I/O. Consider the USON-8 package for space-constrained PCB layouts. Ensure the application does not require automotive-grade certification, as this specific part number is not listed as AEC-Q100 qualified in the provided documentation.

Memory IC Part Context

The GD25LB16E series belongs to GigaDevice's Uniform Sector Dual and Quad Serial Flash family. This series is designed for high-performance code storage with a focus on low power consumption and compact packaging. The GD25LB16ESIGR specifically denotes the 16 Mbit density variant with the 'GR' suffix indicating tape and reel packaging for automated assembly processes.

Memory IC Replacement Considerations

GD25LB16EEIGR: Identical electrical specifications but utilizes an 8-USON (3x2mm) package instead of SOP-8.

Memory IC FAQ

Is the Quad Enable (QE) bit user-configurable?

No, the QE bit is permanently set to 1 by default and cannot be changed, ensuring IO2 and IO3 pins are always enabled for Quad operation.

What is the typical deep power-down current consumption?

The typical deep power-down current is 1 μA.

How many security registers are available?

The device includes three 3x1024-Byte Security Registers, each with One-Time Programmable (OTP) lock bits.
