General Description

The S25FL064K (16-Mbit) Serial Flash memory provides an ideal storage solution for systems with limited space, pins and power. The device offers flexibility and performance well beyond ordinary Serial Flash devices. It is 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 2.7V to 3.6V power supply with current consumption as low as 4 mA active and 1 µA for deep power-down. All devices are offered in space-saving packages. The S25FL064K array is organized into 32,768 programmable pages of 256 bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4-kB sector erase), groups of 128 (32-kB block erase), groups of 256 (64-kB block erase) or the entire chip (chip erase). The S25FL064K has 2048 erasable sectors and 128 erasable blocks respectively. The small 4-kB sectors allow for greater flexibility in applications that require data and parameter storage.
