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.
