Description
The CTK24BC family provides 1K, 2K, 4K, 8K and 16K of serial electrically erasable and programmable
read-only memory (EEPROM). The wide Vdd range allows for low-voltage operation down to 1.8V. The
device, fabricated using traditional CMOS EEPROM technology, is optimized for many industrial and
commercial applications where low-voltage and low-power operation is essential. The device is accessed
via a 2-wire serial interface.
Features
• Internally organized as 128×8(1K), 256×8(2K)
512×8(4K), 1024×8(8K), 2048×8(16K)
• Low-voltage and standard-voltage operation :
1.8~5.5V
• 2-wire serial interface bus
• Date retention : 100 years
• High endurance : 1,000,000 write cycles
• 100kHz(1.8V)& 400kHz(5V) compatibility
• Bi-directional data transfer protocol
• Self-timed write cycle (5ms max)
• Write protect pin for hardware data protection
• 8-byte page (1K, 2K) and 16-byte page (4K, 8K, 16K)
write modes
• Allows for partial page write

Note: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of these specifications are not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.

Device Operation
Clock and Data Transitions: Transitions on the SDA pin should only occur when SCL is low(refer to the
Data Validity timing diagram in Figure 3). If the SDA pin changes when SCL is high, then the transition
will be interpreted as a START or STOP condition.
START Condition: A START condition occurs when the SDA transitions from high to low when SCL is
high. The START signal is usually used to initiate a command(refer to the START and STOP definition
timing diagram in Fig 4)
STOP Condition: A STOP condition occurs when the SDA transitions from low to high when SCLis high.
(refer to the START and STOP definition timing diagram in Fig 4) The STOP command will put the device
into standby mode after no acknowledgement is issued during the read sequence.
Acknowledge: An acknowledgement is sent by pulling the SDA low to confirm that a word has been
successfully received. All addresses and data words are serially transmitted to and from the EEPROM in
8-bit words, so acknowledgements are usually issued during the 9th clock cycle.
Standby Mode: Standby mode is entered when the chip is initially powered-on or after a STOP command
has been issued and any internal operations have been completed.
Memory Reset: In the event of unexpected power or connection loss, a START condition can be issued to
restart the input command sequence. If the device is currently in write cycle mode, this command will be
ignored.
