25LC512T-I/SN Flash Ic Memory EEPROM 512Kbit SPI 20 MHz 8-SOIC

25LC512T-I/SN EEPROM Memory IC 512Kbit SPI 20 MHz 8-SOIC

Description:

The Microchip Technology Inc. 25LC512 is a 512 Kbit serial EEPROM memory with byte-level and page-level

serial EEPROM functions. It also features Page, Sector and Chip erase functions typically associated with Flash-based

products. These functions are not required for byte or page write operations. The memory is accessed via a simple Serial

Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI)

and data out (SO) lines. Access to the device is controlled by a Chip Select (CS) input.
