Description

The 25Q64FW (64M-bit) Serial Flash memory provides a storage solution for systems with limited
space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial
Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 1.65V to 1.95V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in space-saving packages. […]

S25FL129P datasheet

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 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 VCCsupply.

Memory architecture :

1. Uniform 64 KB sectors

2. Top or bottom parameter block (Two 64-KB sectors broken down into sixteen 4-KB sub-sectors each)

3. Uniform 256 KB sectors (no 4-KB sub-sectors)

4. 256-byte page size

5. Backward compatible with the S25FL128P (uniform 256 KB sector) device
