【Description】 The Winbond Flash Memory provides extended megabits and bytes serial flash, used for storage on enhance performance beyond ordinary Serial Flash Devices. This device is ideal for code shadowing to RAM, executing code directly from the Dual Quad SPI storing voice, text, and data. This device operates on a single 2.7v ~ 3.6v power supply with current consumption as low as 4mA active & 1uA for power down. For this demonstration we will going to wire the W25Q80BV an 8Mbit serial flash memory which is available in modular type suited for any microcontroller like Arduino. 【Specification】 W25Q32 = 4Mb W25Q64 = 8Mb W25Q128 =16Mb Using serial nor flash external expansion memory chip W25Q32 Support SPI-interface Provide STM32 test code Main parameters: Capacity: 32M-bit/4M-by
