General Description

The S25FL129P is a 3.0 Volt (2.7V to 3.6V), single-power-supply Flash memory device. The device is offered in two configurations: 256 uniform 64 KB sectors with the two (Top or Bottom) 64 KB sectors further split up into thirty-two 4 KB sub sectors, or 64 uniform 256 KB sectors. The S25FL129P device is backward compatible with the S25FL128P (uniform 256 KB sector) device.

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.

Distinctive Characteristics
