The W25P10 (1M-bit), W25P20 (2M-bit) and W25P40 (4M-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 1A for power-down. All devices are offered in space-saving 8-pin SOIC type packages as shown below. Contact Winbond for availability of alternate packages. As part of a family of Serial Flash products, Winbond also provides a compatible migration path to 8M/16M/32M-bit densities.
The W25P10/20/40 array is organized into 512/1024/2048 programmable pages of 256-bytes each. A single byte or, up to 256 bytes, can be programmed at a time using the Page Program instruction. Pages are grouped into 2/4/8 erasable sectors of 256 pages (64K-byte) each as shown in figure 2. Both Sector Erase and Chip (full chip) Erase instructions are supported.
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 40MHz. 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 ID. Special customer ID (for copy authentication) and factory programming is available, contact Winbond for more information.
The Winbond W25P10/20/40 are fully compatible with the previous NexFlash NX25P10/20/40 Serial Flash memories.
