The S25FL128P is a 3.0 Volt (2.7V to 3.6V), single-power-supply Flash memory device. The device consists
of 64 sectors of 256 KB memory, or 256 sectors of 64 KB memory.
The device accepts data written to SI (Serial Input) and outputs data on SO (Serial Output). The devices are
designed to be programmed in-system with the standard system 3.0 volt VCC supply.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program command. The device
supports Sector Erase and Bulk Erase commands.
Each device requires only a 3.0 volt power supply (2.7V to 3.6V) for both read and write functions. Internally
generated and regulated voltages are provided for the program operations. This device requires a high
voltage supply to WP#/ACC pin for the Accelerated Programming mode.
