W25Q64JVSSIQ

Introduction:

The W25Q64JV is a 64M-bit Serial NOR Flash memory device developed by Winbond, providing a storage solution for systems with limited space, pins, and power requirements. This high-performance device is ideal for applications such as code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data. It operates on a 2.7V to 3.6V power supply with low current consumption and is available in various space-saving packages.

Function & Applications:

The W25Q64JV is designed for a wide range of applications, including automotive, industrial, and consumer electronics. It offers flexibility and performance superior to ordinary Serial Flash devices, with a flexible architecture featuring uniform 4KB sectors. This allows greater adaptability in applications that demand data and parameter storage. Moreover, its support for standard SPI, Dual/Quad I/O SPI, and JEDEC standard ID features makes it compatible with a variety of systems.

Performance Parameters:

The W25Q64JV supports SPI clock frequencies of up to 133MHz, allowing equivalent clock rates of 266MHz (133MHz x 2) for Dual I/O and 532MHz (133MHz x 4) for Quad I/O when using Fast Read Dual/Quad I/O. These transfer rates outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. Additionally, the device boasts a minimum of 100K Program-Erase cycles per sector and more than 20-year data retention, ensuring reliable high-performance operation.

Package Types, Interface & Pin Configuration:

The W25Q64JV is available in various package types, including 8-pin SOIC 208-mil, 8-pad WSON 6x5-mm/8x6-mm, 16-pin SOIC 300-mil, 8-pad XSON 4x4-mm, 24-ball TFBGA 8x6-mm (6x4 ball array), 24-ball TFBGA 8x6-mm (6x4/5x5 ball array), and 12-ball WLCSP. The device supports a range of interfaces, such as standard SPI, Dual SPI, Quad SPI, and QPI, to cater to different application requirements.

Reliability & Lifespan:

With a wide operating temperature range of -40°C to +85°C, and -40°C to +105°C, the W25Q64JV is suitable for harsh environments. Its low power consumption (<1¬µA power-down) ensures energy-efficiency, while advanced security features such as software and hardware write-protect, OTP protection, and unique 64-bit device ID ensure data integrity and protection.

Standards & Certifications:

The W25Q64JV adheres to JEDEC standards for manufacturer and device ID, offering guaranteed quality and compatibility.
