$Fonctionnalités et applications

The 25XX020A* series of 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM)  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 through a Chip Select (CS) input. Communication to the device can be  paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the  exception of Chip Select, allowing the host to service higher priority interrupts. The 25XX020A is available in  standard packages including 8-lead PDIP and SOIC, and advanced packages including 8-lead MSOP, 8-lead  TSSOP and rotated TSSOP, 8-lead 2x3 DFN, and 6-lead SOT-23.
