GD25LE16ESIGR

Memory IC Overview

The GD25LE16ESIGR is a 16M-bit (2M x 8) Serial NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V and supports Standard, Dual, Quad SPI, and QPI interfaces with a maximum clock frequency of 133MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware/software write protection, 128-bit unique ID, and serial flash discoverable parameters.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532Mbits/s in Quad I/O mode.
• Provides comprehensive data protection via software block protect bits, hardware WP# pin control, and one-time programmable security registers.
• Features low power consumption with typical standby current of 10μA and deep power-down current of 0.2μA.
• Ensures high reliability with minimum 100,000 program/erase cycles endurance and 20-year data retention.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip applications
• Firmware storage in consumer electronics and IoT devices
• Data logging and configuration storage in industrial systems

Memory IC Procurement Notes

Verify the specific package variant (SOP8 or USON8) required for your design, as the ESIGR suffix denotes SOP8 while EEIGR denotes USON8. Confirm operating temperature range matches your application requirements (-40°C to +85°C). Ensure voltage supply strictly adheres to the 1.65V-2.0V specification. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a low-voltage (1.8V class) NOR Flash with small form factor is needed. Compare against GD25Q16 series if 3.3V operation is acceptable, as it may offer broader availability. Consider GD25LE16EEIGR if a smaller USON8 package is preferred over SOP8. Evaluate pin compatibility if replacing existing designs, noting that hold and write-protect pins function as I/O in Quad mode.

Memory IC Part Context

The GD25LE16E series belongs to GigaDevice's low-voltage SPI NOR Flash portfolio, targeting cost-sensitive and space-constrained embedded applications. It complements the 3.3V GD25Q series by offering reduced power consumption suitable for battery-operated devices. The uniform sector architecture simplifies file system implementation compared to mixed sector devices.

Memory IC Replacement Considerations

GD25LE16EEIGR offers identical electrical specifications but utilizes an 8-USON package instead of SOP8. GD25Q16ESIGR provides similar functionality but operates at 2.7V-3.6V, requiring voltage level adjustment. Cross-referencing datasheets is essential to confirm pinout and command set compatibility before substitution.
