Description
The AT93C46/56/66 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
AT93C46/56/66 is available in space-saving 8-lead PDIP and 8-lead JEDEC and EIAJ
SOIC packages.

The AT93C46/56/66 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 selftimed 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 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 AT93C56/66 is available in 4.5V to 5.5V, 2.7V to 5.5V, and 2.5V to 5.5V
versions.

Block Diagram
Notes: 1. When the ORG pin is connected to VCC, the x 16 organization is selected. When it is connected to ground, the x 8 orga-
nization is selected. If the ORG pin is left unconnected and the application does not load the input beyond the capability of
the internal 1 Meg ohm pullup, then the x 16 organization is selected. The feature is not available on the 1.8V devices.
2. For the AT93C46, if x 16 organization is the mode of choice and Pin 6 (ORG) is left unconnected, Atmel recommends
using the AT93C46A device. For more details, see the AT93C46A datasheet.

Functional Description
The AT93C46/56/66 is accessed via a simple and versatile 3-wire serial communication
interface. Device operation 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.
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 rising edges of serial clock SK. It should be noted that a
dummy bit (logic “0”) precedes the 8- or 16-bit data output string.
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, programming
remains enabled until an Erase/Write Disable (EWDS) instruction is executed or V
CC
power is removed from the part.
ERASE (ERASE): The Erase (ERASE) instruction programs 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 (t
CS
A logic “1” at pin DO indicates that the selected memory location has been erased, and
the part is ready for another instruction.
WRITE (WRITE): The Write (WRITE) instruction contains the 8 or 16 bits of data to be
written into the specified memory location. The self-timed programming cycle, t
, starts
WP
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 (t
). A logic “0” at DO indicates that programming is still in progress. A logic
CS
“1” indicates that the memory location 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 self-timed programming cycle, t
WP
.
ERASE ALL (ERAL): The Erase All (ERAL) instruction programs every bit in the mem-
ory array to the logic “1” state and is primarily used for testing purposes. 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 (t
). The ERAL instruction is valid only at VCC = 5.0V ± 10%.
CS
WRITE ALL (WRAL): The Write All (WRAL) instruction programs all memory locations
with the data patterns specified 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 (t
The WRAL instruction is valid only at V
= 5.0V ± 10%.
CC
CS
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.
