W25Q32 32M-BIT SERIAL FLASH MEMORY WITH DUAL AND QUAD SPI

  • The W25Q80 (8M-bit), W25Q16 (16M-bit), and W25Q32 (32M-bit) Serial Flash memories provide 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 are offered in space-saving packages.
  • The W25Q80/16/32 array is organized into 4,096/8,192/16,384 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 W25Q80/16/32 has 256/512/1024 erasable sectors and 16/32/64 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in  applications that require data and parameter storage.

  • The W25Q80/16/32 supports the standard Serial Peripheral Interface (SPI), and a high performance  Dual/Quad output as well as Dual/Quad I/O SPI using SPI pins: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 80MHz are  supported allowing equivalent clock rates of 160MHz for Dual Output and 320MHz 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 64-bit Unique Serial Number
