At 133 MHz clock frequency, quad mode achieves 532 MHz equivalent throughput, enabling fast code shadowing and XIP operation. The device supports both 3-byte and 4-byte address modes to access the full 32MB address space. With 4KB, 32KB, and 64KB erase options, program and erase suspend\/resume, and security registers with OTP lock, it provides flexible and secure non-volatile storage in a 16-pin SOIC package.","working_principle":"The W25Q256JVFIQ uses NOR-type flash memory cells organized as 32M x 8 bits. In quad SPI mode, four data lines (SI, SO, WP, HOLD repurposed as SIO0-SIO3) operate simultaneously for 4x throughput. QPI mode uses all four lines for both commands and data. For the full 256Mbit address space, the device uses 4-byte addressing or a bank register with 3-byte addresses. Program and erase suspend\/resume allows interrupting a long erase or program operation to read from a different area, enabling concurrent firmware execution and updates.","pin_description":"
