Description The Atmel® AT24CS04 and AT24CS08 provides 4096/8192 bits of Serial Electrically Erasable and Programmable Read-only Memory (EEPROM) organized as 512/1024 words of eight bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24CS04/08 is available in space-saving, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN and 5-lead SOT23 packages and is accessed via a 2-wire serial interface. In addition, both devices fully operate from 1.7V to 5.5V VCC. The AT24CS04/08 provides the additional feature of a factory programmed, guaranteed unique 128-bit serial number, while maintaining all of the traditional features available in the 4-Kbit or 8-Kbit Serial EEPROM. The time consuming step of performing and ensuring true serialization of product on a manufacturing line can be removed from the production flow by employing the CS Series Serial EEPROM. The 128-bit serial number is programmed and permanently locked from future writing during the Atmel production process. Further, this 128-bit location does not consume any of the user read/write area of the 4-Kbit or 8-Kbit Serial EEPROM. The uniqueness of the serial number is guaranteed across the entire CS Series of Serial EEPROMs, regardless of the size of the memory array or the type of interface protocol. This means that as an application's needs for memory size or interface protocol evolve in future generations, any previously deployed serial number from any Atmel CS Series Serial EEPROM part will remain valid. 2.

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, A1): The AT24CS04 uses the A2 and A1 inputs for hard wire addressing allowing a total of four 4-Kbit devices to be addressed on a single bus system. Pin 1 is a no connect and can be connected to ground. The AT24CS08 only uses the A2 input for hardware addressing and a total of two 8K devices may be addressed on a single bus system. Pins 1 and 2 are no connects and can be connected to ground. Refer to Section 8. “Device Addressing” on page 10 for details about the pin state and the required protocol for communication . The device address pins are not available on the SOT23 package offering. Refer to Section 8. “Device Addressing” on page 10 for details on the protocol requirements with this package. Write Protect (WP): AT24CS04/08 has a Write Protect (WP) pin that provides hardware data protection. When the Write Protect pin is connected to ground (GND), normal read/write operations to the full array are possible. When the Write Protect pin is connected to VCC, all write operations to the memory are inhibited but read operations are still possible. This operation is summarized in Table 5-1 below. Table 5-1.

Atmel AT24CS04/08 [PRELIMINARY DATASHEET] 8766B–SEEPR–8/12 6 7. 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 (see Figure 7-4 on page 9). 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 (see Figure 7-5 on page 9). Stop Condition: A low-to-high transition of SDA with SCL high is a Stop condition. After a read sequence, the Stop command will place the EEPROM in a standby power mode (see Figure 7-5 on page 9). Acknowledge: All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle. Standby Mode: The AT24CS04/08 features a low-power standby mode which is enabled upon power-up as well as after the receipt of the Stop bit and the completion of any internal operations. 2-wire Software Reset: After an interruption in protocol, power loss, or system reset, any 2-wire part can be reset by following these steps: 1. Create a start bit condition. 2. Clock nine cycles. 3. Create another start bit followed by stop bit condition as shown in Figure 7-1. The device is ready for next communication after above steps have been completed. Figure 7-1.

Device Addressing Standard EEPROM Access: The 4-Kbit and 8-Kbit EEPROM device requires an 8-bit device address word following a Start condition to enable the chip for a read or write operation. The device address word consists of a mandatory ‘1010’ (Ah) sequence for the first four most significant bits as shown in Figure 8-1 below. This is common to all Serial EEPROM devices. The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a memory page address bit (P0). The two device address bits must compare to their corresponding hard-wired input pins. Pin 1 is a no connect. The 8K EEPROM only uses the A2 device address bit with the next two bits being for memory page addressing (P1, P0). The A2 must compare to its corresponding hard-wired A2 input pin. Pins 1 and 2 are not connected. 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 compare is not made, the chip will return to a standby state. Note: For the SOT23 package offering, the 4-Kbit EEPROM software A2 and A1 bits in the device address word must be set to zero to properly communicate. The 8-Kbit EEPROM software A2 bit in the device address word must be set to zero to properly communicate in the SOT23 paclkage. Serial Number Access: The AT24CS04 and AT24CS08 utilizes a separate memory block containing a factory programmed 128-bit serial number. Access to this memory location is obtained by beginning the device address word with a ‘1011’ (Bh) sequence. The behavior of the next three bits remain the same as during a standard EEPROM addressing sequence. These three bits must compare to their corresponding hard-wired input pins A2 and A1 (4-Kbit only) in order for the part to acknowledge. The restrictions for these bits with a SOT23 package are the same when accessing the serial number feature. The eighth bit of the device address needs be set to a one to read the Serial Number. A zero in this bit position, other than during a dummy write sequence to set the address pointer, will result in a unknown data read from the part. Writing or altering the 128-bit serial number is not possible. Further specific protocol is needed to read the serial number from of the device. See Read Operations on page 11 for more details on accessing the special feature. Table 8-1.

Write Operations Byte Write: A Byte Write operation requires an 8-bit word address following the device address word and acknowledgment. Upon receipt of this address, the EEPROM will again respond with a zero and then clock in the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a zero and the addressing device, such as a microcontroller, 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 (see Figure 10-1 on page 12). Page Write: The 4-Kbit and 8-Kbit devices are capable of 16-byte Page Writes. A Page Write is initiated in 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 fifteen additional data words. The EEPROM will respond with a zero after each data word received. The microcontroller must terminate the Page Write sequence with a Stop condition (see Figure 10-2 on page 12). The data word address lower four 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 subsequent byte loaded will be placed at the beginning of the same page. If more than sixteen data words are transmitted to the EEPROM, the data word address will roll-over and previously loaded data will be overwritten. 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 the next read or write sequence to begin. 10. Read Operations Read operations are initiated in 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 four types of read operations: Current Address Read Random Address Read Sequential Read Serial Number 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 chip power is maintained. The address roll-over during read is from the last byte of the last memory page to the first byte of the first page. The address roll-over during write is from the last byte of the current page to the first byte of the same page. Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out. The microcontroller does not respond with an zero but does generate a following Stop condition (see Figure 10-3 on page 13). Random Read: A Random Read requires a dummy byte write sequence to load in the data word address. 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. The microcontroller does not respond with a zero but does generate a following Stop condition (see Figure 10-4 on page 13). Sequential Read: Sequential reads are initiated by either a current address read or a random address 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 (see Figure 10-5 on page 13). Atmel AT24CS04/08 [PRELIMINARY DATASHEET] 8766B–SEEPR–8/12 11 Serial Number Read: Reading the serial number is similar to the sequential read sequence but requires use of the device address seen in Figure 10-1 on page 12, a dummy write, and the use of specific word address. Note: The entire 128-bit value must be read from the starting address of the serial number block to guarantee a unique number. Since the address pointer of the device is shared between the EEPROM array and the serial number block, a dummy Write Sequence should be performed to ensure the address pointer is set to zero. Random reads of the serial number block are supported but if the previous operation was to the EEPROM array, the address pointer will retain the last access location, incremented by one. Reading the serial number from a location other than the initial address of the block will not result in a unique serial number. Additionally, the word address must begin with a ‘10’ sequence regardless of the intended address. If a word address other than ‘10’ is used, then the device will output undefined data. Therefore, if the application desires to read the first byte of the serial number, the word address input would need to be 80h. When the end of the 128-bit serial number is reached (16 bytes of data), the data word address will roll-over back to the beginning of the 128-bit serial number. The Serial Number Read operation is terminated when the microcontroller does not respond with an zero (ACK) and instead issues a Stop condition (see Figure 10-6 on page 14). Figure 10-1.
