W25R64JVSSIQ TR

The W25R64JV (64Mb) serial flash provides a storage solution for systems with limited space, pins, and power. The W25 series offers greater flexibility and performance than ordinary serial flash devices. They are well suited for code shadowing to RAM, executing code directly from Dual/Quad SPI, and storing voice, text, and data. The device operates from a single 2.7V to 3.6V supply, with active current consumption as low as 4mA and power-down current of 1μA. All devices are available in space-saving packages. The W25R64JV supports standard SPI, Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0, I/O1, I/O2, and I/O3. SPI clock frequencies up to 133MHz are supported, with equivalent clock rates of 266MHz for Dual I/O and 532MHz for Quad I/O when using Fast Read Dual/Quad I/O instructions. These transfer rates can exceed those of standard asynchronous 8-bit and 16-bit parallel flash. The device supports JEDEC standard manufacturer and device ID, SFDP registers, one 64-bit serial number, and three 256-byte security registers. The W25R series also features an enhanced security function known as the Replay Protected Monotonic Counter. Replay protection provides a high level of secure communication between the flash device and the controller to reduce system vulnerability to hardware attacks.
