Description
The AT93C46B 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 AT93C46B is available in space saving 8-pin
PDIP and 8-pin JEDEC packages.
The AT93C46B 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 pin DO. 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 AT93C46B is available in 4.5V to 5.5V, 2.7V to 5.5V, and 2.5V to 5.5V versions.
