GENERAL DESCRIPTION
The F25S04PA is a 4Megabit, 2.5V only CMOS Serial Flash memory device. The device supports the standard Serial Peripheral Interface (SPI), and a Dual SPI. ESMT’s memory devices reliably store memory data even after 100,000 programming and erase cycles.
The memory array can be organized into 2,048 programmable pages of 256 byte each. 1 to 256 byte can be programmed at a time with the Page Program instruction.
