GD25LQ16EEIGR

Memory IC Overview

The GD25LQ16EEIGR is a 16 Mbit NOR flash memory IC manufactured by GigaDevice. It features a USON-8 package and supports SPI, Dual SPI, Quad SPI, and QPI interfaces with a maximum clock frequency of 133 MHz. The device operates on a single power supply voltage ranging from 1.65 V to 2.1 V. Memory organization consists of 2M x 8 bits, providing uniform 4 KByte sectors and 32/64 KByte blocks. Active read current is typically 15 mA.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532 Mbits/s in quad operations.
• Includes advanced security features such as 128-bit unique ID, software/hardware write protection via WP# pin, and three 3x1024-byte security registers with OTP locks.
• Enables Execute In Place (XiP) operation with continuous read with wrap functionality to reduce data latency and fill SoC cache.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics firmware storage
• Industrial control system configuration memory

Memory IC Procurement Notes

Verify the specific ordering suffix EEIGR against official datasheets to confirm the USON-8 package and 1.65V-2.1V voltage range. Ensure compatibility with system power rails before integration. Confirm moisture sensitivity level and reflow soldering profile requirements during procurement planning.

Memory IC Selection Notes

Select this component when low voltage operation between 1.65V and 2.1V is required. The USON-8 package suits space-constrained designs. Verify interface mode support if high-speed Quad I/O or QPI access is necessary for application performance.

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 variants in the family but is distinguished by its specific voltage range and package type.

Memory IC Replacement Considerations

GD25LQ16ESIGR offers similar electrical characteristics but utilizes an SOP-8 package instead of USON-8. Verify footprint compatibility and thermal requirements when considering substitution.
