25LC640T datasheet

Description :

The Microchip Technology Inc. 25AA640 / 25LC640T / 25LC640(25XX640*) is a 64 Kbit Serial Electrically Erasable PROM [EEPROM]. 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 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.

Features : 

• 8192 x 8 bit organization

• 32 byte page

• Write cycle time: 5ms max.

• Self-timed ERASE and WRITE cycles

• Block write protection
