2mb Serial Flash With 25mhz Spi Bus Interface

The SA25F020 is a 2Mb (512K X 4) CMOS non-volatile serial Flash Memory. This device fully conforms to the SPI 4-wire protocol, is enabled through the Chip Select (CSb) pin, and uses Clock (SCK), Data-in (SI) and Data-out (SO) pins to synchronously control data transfer between the SPI Microcontroller and the Serial Flash memory. The memory CAN be programmed from 1 up to 256 bytes at a time via the Page Program (PP) instruction. The memory is organized into four sectors. Each sector contains 256 pages, with each page being 256 bytes wide. The entire memory CAN therefore be viewed as consisting of 1024 pages, or 262,144 bytes. The SA25F020 is available in a space-saving, 8-lead narrow SOIC package The SA25F020 is part of the SPI Flash and EEPROM family. It is designed to work with any SPI-compatible, high-speed Microcontroller and offers both hardware (WPb pin) and Software (block protect) data protection. For example, programming a 2-bit code into the status Register prevents program with top , top or entire array write protection and enables block write protection. Separate program enable and program disable instructions are provided for additional data protection. Hardware data protection is provided via the WPb pin to protect against inadvertent write attempts to the status Register By Unkown
