AT93C46DN-SH-T

AT93C46DN-SH-T is a 1-Kbit, three-wire automotive temperature serial electrically EEPROM. The device is optimized for use in many automotive applications where low-power and low-voltage operations are essential. It is enabled through the Chip Select (CS) pin and accessed via a three-wire serial interface consisting of data input (DI), data output (DO), and serial data clock (SK). Upon receiving a READ instruction at DI, the address is decoded, and the data is clocked out serially on the DO pin. The write cycle is completely self-timed, and no separate erase cycle is required before write. The write cycle is only enabled when the part is in the erase/write enable state. When CS is brought high following the initiation of a write cycle, the DO pin outputs the Ready/Busy status of the part.
