Description
The Atmel® AT93C56B/66B provides 2,048/4,096 bits of Serial Electrically Erasable
Programmable Read-Only Memory (EEPROM) organized as 128/256 words of 16 bits
each (when the ORG pin is connected to VCC) and 256/512 words of 8 bits each (when
the ORG pin 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 AT93C56B/66B is available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP,
8-pad UDFN, 8-pad XDFN, and 8-ball VFBGA packages.
The AT93C56B/66B 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 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 AT93C56B/66B operates from 1.7V to 5.5V.

Functional Description
The AT93C56B/66B 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 opcode, and the desired memory address location.
Read: The 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 the Serial Clock pin, SK. It should be noted that a dummy bit (Logic 0)
precedes the 8-bit or 16-bit data output string. The AT93C56B/66B supports sequential Read operations. The device will
automatically increment the internal address pointer and clock out the next memory location as long as Chip Select (CS)
is held high. In this case, the dummy bit (Logic 0) will not be clocked out between memory locations, thus allowing for a
continuous stream of data to be read.
Erase/Write Enable (EWEN): To ensure 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.
Note:
Once in the EWEN state, programming remains enabled until an EWDS instruction is executed, or VCC power is
removed from the part.
Erase: The Erase instruction programs all bits in the specified memory location to the Logic 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 tCS. A Logic 1 at the DO pin indicates that the selected
memory location has been erased, and the part is ready for another instruction.
Write: The Write instruction contains the 8-bits or 16-bits of data to be written into the specified memory 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 tCS. 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 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 Memory 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 tCS. The ERAL instruction is valid only at VCC3 (Section 4.2, “DC Characteristics” on page 4).
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 tCS. The WRAL instruction is valid only at VCC3 (Section 4.2).
Erase/Write Disable (EWDS): To protect against accidental data disturbance, 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.
