Serial Flash Memory is a type of non-volatile memory that is commonly used to store data, program code, configuration settings, and other information in a wide range of electronic devices. It is called “serial” because data is read and written sequentially, typically using serial communication protocols like SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

Description
The EN25Q80A is an 8 Megabit (1024K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q80A supports the standard Serial Peripheral Interface (SPI), and a high
performance Dual output as well as Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI),
DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 80MHz are supported allowing
equivalent clock rates of 160MHz for Dual Output and 320MHz for Quad Output when using the
Dual/Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction. […]
