General Description
The S25FL004A is a 3.0 Volt (2.7 V to 3.6 V), single-power-supply Flash memory device. The device consists
of 8 sectors, each with 512 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 V
CC
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 (2.7 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
PP
supply.
