Description
The AT93C46A provides 1024 bits of serial electrically-erasable programmable read-
only memory (EEPROM) organized as 64 words of 16 bits each. The device is opti-
mized for use in many industrial and commercial applications where low-power and
low-voltage operation are essential. The AT93C46A is available in space-saving 8-
lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages.
The AT93C46A is enabled through the Chip Select pin (CS) and accessed via a three-
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 AT93C46A is available in 2.7V to 5.5V and 1.8V to 5.5V versions.
