Publication Number S25FL040A_00
The S25FL040A is a 3.0 Volt (2.7 V to 3.6 V), single-power-supply Flash memory device with with erasable
sectors for boot code and parameter storage.
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 V
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 (2.7 V to 3.6 V) for both read and write functions. Internally
generated and regulated voltages are provided for the program operations. This device does not require a
V
device.
