GD25B32EWIGR

Memory IC Overview

The GD25B32EWIGR is a 32M-bit (4M x 8) Serial NOR Flash memory 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 2.7V to 3.6V. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key electrical characteristics include a typical standby current of 12μA and deep power-down current of 1μA. The component offers 100,000 program/erase cycle endurance and 20-year data retention.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer rates.
• Includes software write protection mechanisms with top/bottom block protection capabilities.
• Integrates advanced security features such as 128-bit unique identification and OTP-locked security registers.
• Enables execute-in-place operation with continuous read wrap functionality to reduce latency.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip architectures
• Firmware storage in consumer electronics devices
• Data logging and parameter storage in industrial control systems

Memory IC Procurement Notes

Verify the specific package variant against the ordering suffix, as the GD25B32E series includes SOP8, USON8, WSON8, and TFBGA options. Confirm that the required voltage range aligns with the 2.7V to 3.6V specification. Ensure compatibility with the host controller's SPI mode support for dual or quad operations if higher speeds are intended.

Memory IC Selection Notes

Select this component when a 32M-bit density is required with a single 3V supply rail. It is suitable for designs needing high-speed read performance up to 133 MHz. Consider the available package types for space-constrained PCB layouts. Verify that the host system can support the necessary command set for page programming and sector erasing operations.

Memory IC Part Context

This part belongs to the GD25B32E family of uniform sector dual and quad serial flash memories. It shares architectural similarities with other members of the GD25 series but is distinct in its 32M-bit capacity and specific voltage operating range. The device is designed to replace older density levels in applications requiring larger code storage within similar pin configurations.

Memory IC FAQ

Is the Quad Enable (QE) bit 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 operations.

What is the default state of the Status Register Protection bits?

The default state for SRP1 and SRP0 is 0, which enables software protection where the status register can be written after issuing a Write Enable command.
