FM25Q32
1. GENERAL DESCRIPTION
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 1µA 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.
The FM25Q32 supports the standard Serial peripheral Interface (SPI), and a high performance
Dual output as well as Dual I/O SPI using pins: Serial Clock, Chip Select, Serial Data I/O0(DI),
Serial Data I/O1(DO). SPI clock frequencies of up to 104MHz are supported allowing equivalent
clock rates of 208MHz for Dual Output and 416Mhz for Quad Output when using the Fast Read
Dual/Quad Output instructions. These transfer rates are comparable to those of 8 and 16-bit
Parallel Flash memories.
A Hold pin, Write protect pin and programmable write protection, with top or bottom array control,
provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer
and device identification with a 4K-bit Secured OTP.
