25CSM04数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The Microchip 25CSM04 is a 4 Mb Serial EEPROM with a Serial Peripheral Interface (SPI) capable of operation across a broad voltage range (2.5V to 5.5V). Thedevice is organized as one block of 524,288 bytes of 8-bits each (512 KByte). It includes a security register with a 128-bit unique serial number and a 256-byte (2048-bit) user-programmable lockable ID page, built in ECC, and a configurable write protection scheme for all bytes.  The 25CSM04 is optimized for use in consumer electronics, industrial, and medical applications where reliable and dependable nonvolatile memorystorage is essential, and is packaged in SOIC, DFN, and WLCSP purchase options.
