With 533 Mbit\/s read throughput in Quad mode, flexible sector architecture (4K\/32K\/64K), 100K erase\/program cycles, and Execute-in-Place (XIP) capability, it is the industry-standard choice for firmware storage, BIOS\/UEFI, and data logging in embedded and computing systems.","working_principle":"The W25Q32JVSIQ is organized as 16,384 programmable pages of 256 bytes each. The memory array is divided into 4 KB sectors, 32 KB and 64 KB blocks. Data is accessed through a Serial Peripheral Interface (SPI) using command-based protocol. Standard SPI uses SI\/SO pins for single-bit data transfer at up to 50 MHz. Dual SPI uses both SI and SO for 2-bit transfer. Quad SPI uses SI, SO, WP, and HOLD pins for 4-bit transfer at 133 MHz, achieving 533 Mbit\/s throughput. Programming is performed page-by-page (256 bytes at a time) after an erase operation. The Execute-in-Place (XIP) feature allows the MCU to execute code directly from the flash without first copying it to RAM.","pin_description":"\n
