GD25B128EWIGY

Memory IC Overview

The GD25B128EWIGY is a 128 Mbit Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133 MHz. The device operates on a single power supply voltage ranging from 2.7 V to 3.6 V. It features a uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. Key electrical parameters include a typical standby current of 14 μA and a deep power-down current of 1 μA. The memory organization consists of 16 MBytes capacity, organized into pages of 256 Bytes.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for flexible data transfer rates up to 532 Mbits/s in Quad I/O mode.
• Includes software write protection mechanisms allowing top/bottom block protection and security register locking.
• Features a reset function via the RESET# pin to return the device to standby mode and clear volatile status bits.
• Provides advanced security features including a 128-bit Unique ID and Serial Flash Discoverable Parameters (SFDP) support.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring execute-in-place (XiP) capability.
• Embedded systems needing reliable firmware storage with uniform sector erase architectures.
• Consumer electronics devices utilizing low-power flash memory for boot code and configuration data.

Memory IC Procurement Notes

Verify the specific package variant required, as the GD25B128E series is available in SOP8, USON8, WSON8, and TFBGA packages. Confirm that the WIGY suffix corresponds to the desired packaging and temperature range specifications. Ensure compatibility with the host controller's SPI interface speed and voltage levels before integration. Check for any special order requirements regarding reset pin configurations or status register protection modes.

Memory IC Selection Notes
