GD25Q127CZIGY

Memory IC Overview

The GD25Q127CZIGY is a 128 Mbit NOR flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 2.7 V to 3.6 V and features an SPI interface with a maximum clock frequency of 104 MHz. The memory organization is specified as 16 M x 8 bits, supporting an active read current of up to 27 mA. This component is housed in a TFBGA-24 package (6x4 mm ball array) and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Quad I/O data transfer modes for efficient code execution and data access.
• Features uniform sector architecture enabling flexible block protection and erase operations.
• Includes hardware-based security registers with OTP lock capabilities for intellectual property protection.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile code storage
• Consumer electronics firmware hosting
• Embedded applications needing high-reliability data retention

Memory IC Procurement Notes

Verify the NRND status before integration, as this designation indicates the component is not recommended for new designs. Confirm package compatibility with the TFBGA-24 footprint and ensure voltage levels align with the 2.7V to 3.6V operational range. Check for moisture sensitivity handling requirements during assembly.

Memory IC Selection Notes

Select this part when a 128 Mbit density is required in a compact TFBGA-24 form factor. Ensure the design supports the 104 MHz SPI clock speed and 3.3V nominal supply. Consider alternative packages like WSON if board space constraints differ, while maintaining the same electrical specifications.

Memory IC Part Context

This component belongs to the GD25Q127C series of SPI NOR flash memories. The 'Z' suffix typically denotes the specific package type, while 'IGY' indicates the industrial temperature grade and tray packaging configuration. It shares core electrical characteristics with other variants in the family but differs in physical dimensions and mounting style.

Memory IC Replacement Considerations

GD25Q127CWIGR offers identical electrical performance in a WSON-8 package. GD25Q127CYIGR provides the same functionality in an 8-WSON package. Verify pinout compatibility and thermal dissipation requirements when substituting between these package types.
