AT93C46/56/66
0172Z–SEEPR–9/05
Functional
Description
The AT93C46/56/66 is accessed via a simple and versatile three-wire serial communi-
cation 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 mem-
ory 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 ENABLE (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 EWEN state, programming remains
enabled until an 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
WP starts
after the last bit of data is received at serial data input pin DI. The DO pin outputs the
Read/Busy status of the part if CS is brought high after being kept low for a minimum of
250 ns (t
CS). A logic “0” at DO indicates that programming is still in progress. A logic “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 tWP.
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
CS). The ERAL instruction is valid only at VCC = 5.0V ± 10%.
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
CS).
The WRAL instruction is valid only at V
CC = 5.0V ± 10%.
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.
