Device Power Supply
Note:
1. The exposed pad on this package can be connected to GND or left floating.
2.1
Chip Select (CS)
The Chip Select (CS) pin is used to control device selection. The AT93C56B/AT93C66B is selected when the CS pin
is high. When the device is not selected, data will not be accepted via the Serial Data Input (DI) pin, and the Serial
Output (DO) pin will remain in a high-impedance state.
2.2
Serial Data Clock (SK)
The Serial Data Clock (SK) pin is used to synchronize the communication between a master and the AT93C56B/
AT93C66B. Instructions, addresses or data present on the Serial Data Input (DI) pin is latched in on the rising edge of
SK, while output on the Serial Data Output (DO) pin is also clocked out on the rising edge of SK.
2.3
Serial Data Input (DI)
The Serial Data Input (DI) pin is used to transfer data into the device. It receives instructions, addresses and data.
Data is latched on the rising edge of the Serial Data Clock (SK).
2.4
Serial Data Output (DO)
The Serial Data Output (DO) pin is used to transfer data out of the AT93C56B/AT93C66B. During a read sequence,
data is shifted out on this pin after the rising edge of the Serial Data Clock (SK).
This pin also outputs the Ready/Busy status of the part if CS is brought high after being low for a minimum of tcs and
an erase or write operation has been initiated.
2.5
Ground (GND)
The ground reference for the power supply. The Ground (GND) pin should be connected to the system ground.

2.6
Internal Organization (ORG)
The Internal Organization (ORG) pin is used to select between the x16 or x8 memory organizations of the device.
When the ORG pin is tied to VCC, the x16 memory organization is selected. When the ORG pin is tied to VSS, the x8
memory organization is selected.
If the ORG pin is left unconnected and the application does not load the input beyond the capability of the internal 1
MΩ pull-up resistor, then the x16 organization is selected.
2.7
Device Power Supply (VCC)
The Device Power Supply (VCC) pin is used to supply the source voltage to the device. Operations at invalid VCC
voltages may produce spurious results and should not be attempted.

Description
The AT93C56B/AT93C66B provides 2,048/4,096 bits of Serial Electrically Erasable and 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/AT93C66B
is available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-pad XDFN and 8-ball VFBGA packages. All
packages operate from 1.7V to 5.5V.
The AT93C56B/AT93C66B is enabled through the Chip Select (CS) pin and accessed via a three-wire serial interface
consisting of Data Input (DI), Data Output (DO), and Serial Data 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.

AT93C56B/AT93C66B
Electrical Characteristics
4.6
4.6.1
Electrical Specifications
Power-Up Requirements and Reset Behavior
During a power-up sequence, the VCC supplied to the AT93C56B/AT93C66B should monotonically rise from GND to
the minimum VCC level, as specified in Table 4-1, with a slew rate no faster than 0.1 V/µs.
4.6.1.1
Device Reset
To prevent inadvertent write operations or any other spurious events from occurring during a power-up sequence, the
AT93C56B/AT93C66B includes a Power-on Reset (POR) circuit. Upon power-up, the device will not respond to any
commands until the VCC level crosses the internal voltage threshold (VPOR) that brings the device out of Reset and
into Standby mode.
The system designer must ensure the instructions are not sent to the device until the VCC supply has reached a
stable value greater than or equal to the minimum VCC level. Additionally, once the VCC is greater than or equal to the
minimum VCC level, the bus master must wait at least tPUP before sending the first command to the device. See
Power-up Conditions(1) for the values associated with these power-up parameters.

Note:
1. These parameters are characterized but they are not 100% tested in production.
If an event occurs in the system where the VCC level supplied to the AT93C56B/AT93C66B drops below the
maximum VPOR level specified, it is recommended that a full power cycle sequence be performed by first driving the
VCC pin to GND, waiting at least the minimum tPOFF time and then performing a new power-up sequence in
compliance with the requirements defined in this section.

Device Commands and Addressing
The AT93C56B/AT93C66B is accessed via a simple and versatile three-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 (SB), followed by the appropriate opcode, and the desired memory address location.

5.1
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 DO pin. Output data changes are
synchronized with the rising edges of the SK pin. The AT93C56B/AT93C66B 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.
Note: A dummy bit (logic ‘0’) precedes the initial 8-bit or 16-bit data output string.

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 write enabled state, programming remains enabled until an EWDS instruction is executed, or VCC
power is removed from the part.

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.

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 selftimed programming cycle, tWP, starts after the last bit of data is received at DI pin . 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.

Microchip Devices Code Protection Feature
Note the following details of the code protection feature on Microchip devices:
•
•
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today,
when used in the intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these
methods, to our knowledge, require using the Microchip products in a manner outside the operating
specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of
intellectual property.

Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code
protection does not mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection
features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital
Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you
may have a right to sue for relief under that Act.
