Pin Description  
Serial Clock (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative  
edge clock data out of each device.  
Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open drain driven and may be  
wire-ORed with any number of other open drain or open collector devices.  
Device Addresses (A2 and A1): The A2 and A1 pins are device address inputs that can be hardwired or left not  
connected for hardware compatibility with other Atmel AT24Cxx devices. When the A2 and A1 pins are  
hardwired, as many as four 1-Mbit devices may be addressed on a single bus system (See “Device Addressing”  
on page 9. for more details). If the A2 and A1 pins are left floating, the A2 and A1 pin will be internally pulled down  
to GND if the capacitive coupling to the circuit board VCC plane is <3pF. If coupling is >3pF, Atmel recommends  
connecting the A2 and A1 pin to GND.  
Write Protect (WP): The Write Protect input, when connected to GND, allows normal write operations. When  
WP is connected high to VCC, all write operations to the memory are inhibited. If the pin is left floating, the WP  
pin will be internally pulled down to GND if the capacitive coupling to the circuit board VCC plane is <3pF. If  
coupling is >3pF, Atmel recommends connecting the pin to GND. Switching WP to VCC prior to a write operation  
creates a software write protect function.

Device Operation  
Clock and Data Transitions: The SDA pin is normally pulled high with an external device. Data on the SDA pin  
may change only during SCL low time periods. Data changes during SCL high periods will indicate a Start or  
Stop condition as defined below.

Start Condition: A high-to-low transition of SDA with SCL high is a Start condition which must precede any  
other command.  
Stop Condition: A low-to-high transition of SDA with SCL high is a Stop condition. After a read sequence, the  
Stop condition will place the EEPROM in a standby power mode.

Standby Mode: The AT24CM01 features a low-power standby mode which is enabled:  
Upon power-up.  
After the receipt of the Stop condition and the completion of any internal operation.  
Software Reset: After an interruption in protocol, power loss, or system reset, any 2-wire part can be protocol  
reset by following these steps:  
1. Create a Start condition (if possible).  
2. Clock nine cycles.  
3. Create another Start condition followed by Stop condition as in Figure 6-4.  
The device should be ready for the next communication after the above steps have been completed. In the  
event that the device is still non-responsive or remains active on the SDA bus, a power cycle must be used to  
reset the device.

Device Addressing  
The 1-Mbit EEPROM requires an 8-bit device address word following a Start condition to enable the chip for a  
read or write operation (see Figure 7-1 below). The device address word consists of a mandatory ‘1010’  
sequence for the first four most significant bits. This is common to all 2-wire EEPROM devices.  
The 1-Mbit uses the two device address bits, A2 and A1, to allow up to four devices on the same bus. These A2  
and A1 bits must compare to the corresponding hardwired input pins, A2 and A1. The A2 and A1 pins uses an  
internal proprietary circuit that biases it to a logic low condition if the pin is allowed to float.  
The seventh bit (P0) of the device address is a memory page address bit. This memory page address bit is the  
most significant bit of the data word address that follows. The eighth bit of the device address is the read/write  
operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low.  
Upon a compare of the device address, the EEPROM will output a zero. If a valid compare is not made, the  
device will return to a standby state.

Write Operations  
Byte Write: To select a data word in the 1-Mbit memory requires a 17-bit word address. The word address field  
consists of the P0 bit in the device address byte, then the most significant word address followed by the least  
significant word address (Figure 8-1).  
A write operation requires the P0 bit and two 8-bit data word addresses following the device address word and  
acknowledgment. Upon receipt of this address, the EEPROM will again respond with a zero and then the part is  
to receive the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a zero. The  
addressing device, such as a microcontroller, then must terminate the write sequence with a Stop condition. At  
this time the EEPROM enters an internally timed write cycle, tWR, to the nonvolatile memory. All inputs are  
disabled during this write cycle and the EEPROM will not respond until the write is complete (Figure 8-1).

Page Write: The 1-Mbit EEPROM is capable of a 256-byte Page Write.  
A Page Write is initiated the same way as a Byte Write, but the microcontroller does not send a Stop condition  
after the first data word is clocked in. Instead, after the EEPROM acknowledges receipt of the first data word,  
the microcontroller can transmit up to 255 more data words. The EEPROM will respond with an acknowledge  
after each data word is received. The microcontroller must terminate the page write sequence with a Stop  
condition (Figure 8-2) and the internally timed write cycle will begin.  
The data word address lower 8 bits are internally incremented following the receipt of each data word. The  
higher data word address bits are not incremented, retaining the memory page row location. When the internally  
generated word address, reaches the page boundary, the following byte is placed at the beginning of the same  
page. If more than 256 data words are transmitted to the EEPROM, the data word address will “roll over” and  
previous data will be overwritten. The address “rollover” during write is from the last byte of the current page to  
the first byte of the same page.

Acknowledge Polling: Once the internally timed write cycle has started and the EEPROM inputs are disabled,  
Acknowledge Polling can be initiated. This involves sending a Start condition followed by the device address  
word. The read/write bit is representative of the operation desired. Only if the internal write cycle has completed  
will the EEPROM respond with a zero, allowing a new read or write sequence to be initiated.  
Data Security: The AT24CM01 has a hardware data protection scheme that allows the user to write protect the  
entire memory when the WP pin is at VCC  
.

Read Operations  
Read operations are initiated the same way as write operations with the exception that the read/write select bit  
in the device address word is set to one. There are three read operations: Current Address Read, Random  
Address Read, and Sequential Read.  
Current Address Read: The internal data word address counter maintains the last address accessed during  
the last read or write operation, incremented by one. This address stays valid between operations as long as the  
VCC to the part is maintained. The address “rollover” during read is from the last byte of the last page, to the first  
byte of the first page of the memory.  
Once the device address with the read/write select bit set to one is input and acknowledged by the EEPROM,  
the current address data word is serially clocked out on the SDA line. The microcontroller does not respond with  
a zero but does generate a following Stop condition.

Random Read: A Random Read requires an initial byte write sequence to load in the data word address. This  
is known as a “dummy write” operation. Once the device address word and data word address are clocked in  
and acknowledged by the EEPROM, the microcontroller must generate another Start condition. The  
microcontroller now initiates a current address read by sending a device address with the read/write select bit  
high. The EEPROM acknowledges the device address and serially clocks out the data word on the SDA line.  
The microcontroller does not respond with a zero but does generate a following Stop condition.

Sequential Read: Sequential Reads are initiated by either a Current Address Read or a Random Read. After  
the microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM receives  
an acknowledge, it will continue to increment the data word address and serially clock out sequential data  
words. When the memory address limit is reached, the data word address will “roll over” and the sequential read  
will continue. The Sequential Read operation is terminated when the microcontroller does not respond with a  
zero, but does generate a following Stop condition.
