GD25S512MDYEGR

Memory IC Overview

The GD25S512MDYEGR is a 3.3V uniform sector dual and quad serial flash memory manufactured by GigaDevice Semiconductor (HK) Limited. It features a stacked die architecture comprising two 256M-bit GD25B256D dies within an 8-pin WSON package, providing a total capacity of 512 Mbit organized as 64M x 8. The device supports standard SPI, Dual SPI, and Quad SPI interfaces with maximum clock frequencies up to 104 MHz at 3.0-3.6V and 80 MHz at 2.7-3.6V. Operating voltage ranges from 2.7V to 3.6V, with active read current typically at 25 mA. It offers concurrent operations, allowing independent access to each die for improved throughput.

Memory IC Feature Summary

• Stacked die architecture enabling concurrent operations for independent single-die access and multi-die program/erase capabilities.
• Supports Standard, Dual, and Quad SPI interfaces with data transfer rates up to 416 Mbits/s in Quad mode.
• Includes advanced security features such as software write protection, OTP lockable security registers, and a unique ID.
• Provides flexible architecture with uniform sectors and blocks, supporting both 3-byte and 4-byte addressing modes.

Memory IC Applications

• Applications requiring high program/erase data throughput in low pin-count packages.
• Systems utilizing stacked die configurations for enhanced performance.
• Embedded designs needing secure code storage with hardware-level protection mechanisms.

Memory IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm interface support for Dual or Quad SPI if higher speeds are required. Check for any special order requirements regarding RESET# pin availability on specific packages.

Memory IC Selection Notes

Select this component when high density is needed in an 8-pin footprint. Consider the stacked die structure for applications benefiting from concurrent operations. Verify that the host controller supports the required SPI modes and address lengths. Ensure thermal management aligns with the specified operating temperature range.
