Preliminary - Revision I

W25X10, W25X20, W25X40, W25X80

1. GENERAL DESCRIPTION

The W25X10 (1M-bit), W25X20 (2M-bit), W25X40 (4M-bit) and W25X80 (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 2.7V 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 W25X10/20/40/80 array is organized into 512/1024/2048/4096 programmable pages of 256-bytes

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 W25X10/20/40/80 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 W25X10/20/40/80 supports the standard Serial Peripheral Interface (SPI), and a high

performance dual output SPI using four pins: Serial Clock, Chip Select, Serial Data I/O and Serial

Data Out. SPI clock frequencies of up to 75MHz are supported allowing equivalent clock rates of

150MHz when using the Fast Read Dual Output instruction. These transfer rates are comparable 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 identification.
