SUMMARY DESCRIPTION nThe M25Pxx is a 512Kbit to 32Mbit (2M x 8) Serial Flash Memory, with advanced write protection mechanisms, accessed by a high speed SPI-com patible bus. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. The memory is organized as a number of sectors, each containing 256 or 128 pages. Each page is 256 bytes wide.nFEATURES SUMMARY n■ 512Kbit to 32Mbit of Flash Memory n■ Page Program (up to 256 Bytes) in 1.4ms (typical) n■ Sector Erase (256 Kbit or 512Kbit) n■ Bulk Erase (512Kbit to 32Mbit) n■ 2.7 to 3.6V Single Supply Voltage n■ SPI Bus Compatible Serial Interface n■ 40MHz to 50MHz Clock Rate (maximum) n■ Deep Power-down Mode 1µA (typical) n■ Electronic Signatures n– JEDEC Standard Two-Byte Signature (20xxh) n– RES Instruction, One-Byte, Signature, for backward compatibility n■ More than 100000 Erase/Program Cycles per Sector n■ More than 20 Year Data Retention
