GD25LQ16EWIGR

Memory IC Overview

The GD25LQ16EWIGR is a 16 Mbit (2M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65 V to 2.1 V and supports SPI, Dual SPI, Quad SPI, and QPI 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/software write protection, 128-bit unique ID, and three 1024-Byte security registers with OTP locks. The component is housed in an 8-lead WSON package.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532 Mbits/s.
• Provides software and hardware write protection mechanisms including block protect bits and WP# pin control.
• Includes 128-bit unique identification and three 1024-Byte security registers with one-time programmable lock capabilities.
• Enables Execute In Place (XiP) operation with continuous read wrap functionality to reduce instruction fetch latency.

Memory IC Applications

• Firmware storage for embedded systems requiring low voltage operation
• Code execution directly from flash memory (XiP)
• Secure data storage utilizing hardware write protection and unique IDs

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature range compatibility. Ensure the design accommodates the 1.65 V to 2.1 V supply voltage requirements. Confirm that the target application supports the required SPI or QPI interface protocols before procurement.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation between 1.65 V and 2.1 V. It is suitable for designs needing high-speed data access via Quad SPI or QPI modes. Consider the WSON-8 package dimensions for PCB layout constraints. Verify that the system supports the necessary command set for security register programming if protection features are utilized.

Memory IC Part Context

This part belongs to the GD25LQ16E series of uniform sector dual and quad serial flash memories. It shares architectural similarities with other devices in the GD25LQ family but is distinguished by its specific 16 Mbit capacity and low-voltage operating range. The WSON-8 package variant provides a compact surface-mount solution for space-constrained designs.
