W25Q32 refers to a specific model of serial flash memory produced by Winbond Electronics Corporation. In particular, the "W25Q32" is part of the W25Q series, which consists of a range of flash memory chips differing in capacity and features. Standard SPI Instructions: The W25Q32JV is accessed through an SPI-compatible bus consisting of four signals: Serial Clock (CLK), Chip Select (/CS), Serial Data Input (DI), and Serial Data Output (DO). Standard SPI instructions use the DI input pin to serially write instructions, addresses, or data to the device on the rising edge of CLK. The DO output pin reads data or status from the device on the falling edge of CLK. SPI bus operation Mode 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and Mode 3 concerns the normal state of the CLK signal when the SPI bus master is on standby and data is not being transferred to the Serial Flash. For Mode 0, the CLK signal is typically low on the falling and rising edges of /CS. For Mode 3, the CLK signal is usually high on the falling and rising edges of /CS. Dual SPI Instructions: The W25Q32JV supports Dual SPI operation when using instructions such as "Fast Read Dual Output (3Bh)" and "Fast Read Dual I/O (BBh)". These instructions allow data to be transferred to or from the device at two to three times the rate of ordinary Serial Flash devices. The Dual SPI Read instructions are ideal for quickly downloading code to RAM upon power-up (code-shadowing) or for executing non-speed-critical code directly from the SPI bus (XIP). When using Dual SPI instructions, the DI and DO pins become bidirectional I/O pins: IO0 and IO1.
