S25FL129P0XMFI001

The S25FL129P0XMFI001 is a 128MB CMOS Flash Memory with 104MHz SPI (serial peripheral interface) multi I/O bus. The device is offered in two configurations - 256 uniform 64kB sectors with the two 64kB sectors further split up into thirty-two 4kB sub sectors or 64 uniform 256kB sectors. The S25FL129P device is backward compatible with the S25FL128P (uniform 256kB sector) device. The device accepts data written to SI (serial input) and outputs data on SO (serial output). The device is designed to be programmed in-system with the standard system 3VCC 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. The device requires only a 3V power supply 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 the W#/ACC pin to enable the Accelerated Programming mode.
