W25Q64 NOR Flash 64MB Memory Module

Description

The W25Q64JV is a high-capacity Serial Flash memory IC with 64 megabits (Mb) or 8 megabytes (MB) of storage, featuring a standard Serial Peripheral Interface (SPI) for easy interfacing with digital devices. It supports Quad SPI mode, offering fast read and write operations, and is organized into uniform 4KB sectors for efficient data management.

These modules are useful for offering non-volatile storage for audio, image, or sensor data files. As the module operates at 3.3V, caution must be taken when using it with a 5V MCU to prevent potential damage. Level shifters are necessary in such cases. The module is equipped with a power LED and a 2K current-limiting resistor for added convenience and safety during operation.

The memory operates within a wide voltage range, typically supporting 2.7V to 3.6V (Vcc) and 2.3V to 3.6V (VccQ). It includes power-saving features and has a high endurance rating of over 100,000 erase/write cycles per sector. Additionally, it offers data protection through Write Protection and Lock-Down functions and operates reliably in industrial temperature ranges from -40°C to +85°C. The W25Q64JV is RoHS compliant, meeting environmental standards and regulations.
