3. TECHNICAL BRIEF
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.
