W25X10L, W25X20L, W25X40L, W25X80L 1M-BIT, 2M-BIT, 4M-BIT AND 8M-BIT 2.5V SERIAL FLASH MEMORY WITH 4KB SECTORS AND DUAL OUTPUT SPI Publication Release Date: February 27, 2008 -1- Revision I W25X10L, W25X20L, W25X40L, W25X80L 1. GENERAL DESCRIPTION The W25X10L (1M-bit), W25X20L (2M-bit), W25X40L (4M-bit) and W25X80L (8M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.5V ( a range of 2.3V to 3.3V) power supply with current consumption as low as 5m A active and 1µA for power-down. All devices are offered in space-saving packages. The W25X10L/20L/40L/80L array is organized into 512/1024/2048/4096 programmable pages of 256bytes each. Up to 256 bytes can be programmed at a time using the Page Program instruction. Pages can be erased in groups of 16 (sector erase), groups of 256 (block erase) or the entire chip (chip erase). The W25X10L/20L/40L/80L has 32/64/128/256 erasable sectors and 2/4/8/16 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.) The W25X10L/20L/40L/80L supports the standard Serial Peripheral Interface (SPI), and a high performance dual output SPI and low voltage operation using four pins: Serial Clock, Chip Select, Serial Data I/O and Serial Data Out. SPI clock frequencies of up to 40MHz are supported allowing equivalent clock rates of 80MHz when using the Fast Read Dual Output instruction. These transfer rates are parable to those of 8 and 16-bit Parallel Flash memories. A Hold pin, Write Protect pin and programmable write protect, with top or bottom array control Features , provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device...
