GD25Q256EFIRY

Memory IC Overview

The GD25Q256EFIRY is a 256 Mbit (32M x 8) NOR flash memory manufactured by GigaDevice. It features a 16-lead SOP package and supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 133 MHz. The device operates on a single power supply ranging from 2.7 V to 3.6 V. It provides uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. Key electrical characteristics include a typical standby current of 16 μA and deep power-down current of 1 μA.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer speeds.
• Includes advanced security features such as hardware write protection via the WP# pin and software block protection.
• Enables execute-in-place (XiP) operation for direct code execution without data transfer overhead.
• Features a uniform sector architecture allowing granular erasure and programming operations.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications needing reliable firmware retention
