GD25Q64EZIGY

Memory IC Overview

The GD25Q64EZIGY is a 64M-bit (8M x 8) 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 ranging from 2.7V to 3.6V. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key specifications include a typical page program time of 0.5ms, block erase times of 150ms or 250ms, and chip erase time of 25s. Data retention is typically 20 years with endurance of at least 100,000 program/erase cycles.

Memory IC FAQ

What is the function of the QE bit in the Status Register?

The Quad Enable (QE) bit allows Quad SPI operation. When set to 1, the WP# and HOLD# pins act as bidirectional I/O pins (IO2 and IO3). When 0, these pins retain their dedicated functions.

How does the Hold function work?

The Hold function pauses serial communication without resetting internal logic. It requires CS# to remain low and starts on the falling edge of HOLD# when SCLK is low. It ends on the rising edge of HOLD# when SCLK is low.
