Figure. 3.6.1 MEMORY BLOCK DIAGRAM
The FM25Q32 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 devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and
1 A for power-down. All devices offered in space-saving packages.
The FM25Q32 array is organized into 16.384 programmable pages of 256-bytes each. Up to 256 bytes can be
programmed at a time using the Page Program instructions. Pages can be erased in groups of 16 (sector erase)
groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The FM25Q32
has 1,024 erasable sectors and 64 erasable blocks respectively. The small 4KB sectors allow for greater flexibility
in applications that require data and parameter storage.
