Description
The AT93C46/56/57/66 provides 1024/2048/4096 bits of serial electrically erasable
programmable read only memory (EEPROM) organized as 64/128/256 words of 16
bits each, when the ORG Pin is connected to VCC and 128/256/512 words of 8 bits
each when it is tied to ground. The device is optimized for use in many industrial and
commercial applications where low power and low voltage operations are essential.
The AT93C46/56/57/66 is available in space saving 8-pin PDIP and 8-pin JEDEC and
EIAJ SOIC packages.

DO
The AT93C46/56/57/66 is enabled through the Chip Select
pin (CS), and accessed via a 3-wire serial interface consist-
ing 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 out-
puts the READY/BUSY status of the part.
The AT93C46 is available in 4.5V to 5.5V, 2.7V to 5.5V,
2.5V to 5.5V, and 1.8V to 5.5V versions. The
AT93C56/57/66 is available in 4.5V to 5.5V, 2.7V to 5.5V,
and 2.5V to 5.5V versions.

Block Diagram
Note:
1. When the ORG pin is connected to VCC, the x 16 organization is selected. When it is connected to ground, the x 8 organiza-
tion is selected. If the ORG pin is left unconnected, then an internal pullup device (of approximately 1 MΩ) will select the x
16 organization. This feature is not available on 1.8V devices.

Functional Description
The AT93C46/56/57/66 is accessed via a simple and ver-
satile 3-wire serial communication interface. Device opera-
tion is controlled by seven instructions issued by the host
processor. A valid instruction starts with a rising edge
of CS and consists of a Start Bit (logic ‘1’) followed by the
appropriate Op Code and the desired memory Address
location.
WRITE (WRITE): The Write (WRITE) instruction contains
the 8 or 16 bits of data to be written into the specified mem-
ory location. The self-timed programming cycle, tWP, starts
after the last bit of data is received at serial data input pin
DI. The DO pin outputs the READY/BUSY status of the part
if CS is brought high after being kept low for a minimum of
250 ns (tCS). A logic ‘0’ at DO indicates that programming is
still in progress. A logic ‘1’ indicates that the memory loca-
tion at the specified address has been written with the data
pattern contained in the instruction and the part is ready for
further instructions. A READY/BUSY status cannot be
obtained if the CS is brought high after the end of the
READ (READ): The Read (READ) instruction contains
the Address code for the memory location to be read. After
the instruction and address are decoded, data from the
selected memory location is available at the serial output
pin DO. Output data changes are synchronized with the ris-
ing edges of serial clock SK. It should be noted that a
dummy bit (logic ‘0’) precedes the 8- or 16-bit data output
string.
self-timed programming cycle, tWP
.
ERASE ALL (ERAL): The Erase All (ERAL) instruction
programs every bit in the memory array to the logic ‘1’ state
and is primarily used for testing purposes. The DO pin out-
puts the READY/BUSY status of the part if CS is brought
high after being kept low for a minimum of 250 ns (tCS). The
ERAL instruction is valid only at VCC = 5.0V ± 10%.
ERASE/WRITE (EWEN): To assure data integrity, the
part automatically goes into the Erase/Write Disable
(EWDS) state when power is first applied. An Erase/Write
Enable (EWEN) instruction must be executed first before
any programming instructions can be carried out. Please
note that once in the Erase/Write Enable state, program-
ming remains enabled until an Erase/Write Disable
(EWDS) instruction is executed or VCC power is removed
from the part.
WRITE ALL (WRAL): The Write All (WRAL) instruction
programs all memory locations with the data patterns spec-
ified in the instruction. The DO pin outputs the
READY/BUSY status of the part if CS is brought high after
being kept low for a minimum of 250 ns (tCS). The WRAL
instruction is valid only at VCC = 5.0V ± 10%.
ERASE (ERASE): The Erase (ERASE) instruction pro-
grams all bits in the specified memory location to the logical
‘1’ state. The self-timed erase cycle starts once the ERASE
instruction and address are decoded. The DO pin outputs
the READY/BUSY status of the part if CS is brought high
after being kept low for a minimum of 250 ns (tCS). A logic
‘1’ at pin DO indicates that the selected memory location
has been erased, and the part is ready for another instruc-
tion.
ERASE/WRITE DISABLE (EWDS): To protect against
accidental data disturb, the Erase/Write Disable (EWDS)
instruction disables all programming modes and should be
executed after all programming operations. The operation
of the READ instruction is independent of both the EWEN
and EWDS instructions and can be executed at any time.
