Description
The Atmel^® AT93C46E provides 1,024 bits of Serial Electrically-Erasable
Programmable Read-Only Memory (EEPROM) organized as 64 words of 16 bits
each. The device is optimized for use in many industrial and commercial
applications where low-power and low-voltage operation are essential. The
AT93C46E is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC,
8-lead, and TSSOP packages.
The AT93C46E is enabled through the Chip Select pin (CS) and accessed via a
3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift
Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and
the data is clocked out serially on the data output 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.
The AT93C46E is available from 1.8V to 5.5V.
