General Description

The S25FL004A device is a 3.0 Volt (2.7 V to 3.6 V) single power supply Flash

memory device. S25FL004A consists of eight sectors, each with 512 Kb memory.

Data appears on SI input pin when inputting data into the memory and on the SO

output pin when outputting data from the memory. 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 Pro-

gram instruction.

The memory supports Sector Erase and Bulk Erase instructions.

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 VPP supply.
