GENERAL DESCRIPTION The W25P80 (8M-bit) and W25P16 (16M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. Devices are offered in space-saving SOIC packages. As part of a family of Serial Flash products, Winbond also offers compatible devices in 1M/2M/4M-bit densities. The W25P80/16 array is organized into 4,096/8,192 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time using the Page Program instruction. Pages are grouped into 16/32 erasable sectors of 256 pages (64K-byte) each as shown in figure 2. Both Sector Erase and Chip (full chip) Erase instructions are supported. Additionally, a 256-byte Parameter Page is provided for user data that is typically stored in EEPROMs such as ID or revision numbers and configuration parameters. The parameter page is separate from the main array allowing for much faster erase times. The Serial Peripheral Interface (SPI) consists of four pins (Serial Clock, Chip Select, Serial Data In and Serial Data Out) that support high speed serial data transfers up to 50MHz. A Hold pin, Write Protect pin and programmable write protect features provide further control flexibility. Additionally, the device can be queried for manufacturer and device type. The Winbond W25P80/16 are fully compatible with the previous NexFlash NX25P80/16 Serial Flash memories. 2.
