Description The Atmel® AT24CS64 provides 65,536 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 8,192 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24CS64 is available in space-saving, 8-lead JEDEC SOIC, 8-lead TSSOP, and 8-pad UDFN packages and is accessed via a 2-wire serial interface. Full operation is guaranteed from 1.7V to 5.5V VCC. The AT24CS64 provides the additional feature of a factory programmed, guaranteed unique 128-bit serial number, while maintaining all of the traditional features available in the 64-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 64-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/Page Addresses (A2, A1, A0): The A2, A1, and A0 pins are device address inputs that are hard wired for the AT24CS64. As many as eight 64-Kbit devices may be addressed on a single bus system. For more detail, see Section 8., “Device Addressing” on page 10. Write Protect (WP): AT24CS64 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.

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 in Figure 7-2. Figure 7-1. Data Validity SDA SCL Data Stable Data Stable Data Change 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 command will place the EEPROM in a standby power mode. Figure 7-2. Start and Stop Definition SDA SCL Start Stop AT24CS64 [DATASHEET] Atmel-8870D-SEEPROM-AT24CS64-Datasheet_012015 7 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. Figure 7-3. Output Acknowledge 1 SCL 8 9 DATA IN DATA OUT Start Acknowledge Standby Mode: The AT24CS64 features a low-power standby mode which is enabled upon power-up as well as after the receipt of the Stop condition 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 condition (if possible). 2. 3. Clock nine cycles. Create another Start condition followed by Stop condition. The device should be ready for the next communication after 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. Figure 7-4.

AT24CS64 [DATASHEET] Atmel-8870D-SEEPROM-AT24CS64-Datasheet_012015 9 8. Device Addressing Standard EEPROM Access: The 64K 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. This is common to all Serial EEPROM devices. The next three bits are the A2, A1, and A0 device address bits for the 64K EEPROM. These three bits must compare to their corresponding hard-wired input pins A2, A1, and A0 in order for the part to acknowledge. 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 valid compare of the device address with hard-wired input pins A2, A1, and A0, the EEPROM will output a zero. If a compare is not successfully made, the chip will return to a standby state. Serial Number Access: The AT24CS64 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 (A2, A1, and A0) remain the same as during a standard EEPROM addressing sequence. These three bits must compare to their corresponding hard-wired input pins A2, A1, and A0 in order for the part to acknowledge. 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 Section 10., “Read Operations” on page 12 for more details on accessing the special feature. Table 8-1.

Write Operations Byte Write: A Byte Write operation requires 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 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 (see Figure 7-6). All inputs are disabled during this write cycle and the EEPROM will not respond until the Write is complete (see Figure 9-1). Figure 9-1. Byte Write S T A R T Device Address W R I T E First Word Address Second Word Address S T O P Data SDA Line M S B Note: R A / C W K A C K A C K A C K * = Don't care bit. Page Write: The 64K EEPROM is capable of a 32-byte Page Write. 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 31 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. Figure 9-2.

The data word address lower five 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 eight 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. AT24CS64 [DATASHEET] Atmel-8870D-SEEPROM-AT24CS64-Datasheet_012015 11 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 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 a zero but does generate a following Stop condition. Figure 10-1. Current Address Read S T A R T Device Address R E A D S T O P Data SDA LINE N O R A / C WK M S B A C K 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. Figure 10-2.

AT24CS64 [DATASHEET] Atmel-8870D-SEEPROM-AT24CS64-Datasheet_012015 L A S C B K R A / C WK N O A C K 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. Figure 10-3. Device Address Sequential Read R E A D Data (n) Data (n + 1) Data (n + 2) S T O P Data (n + x) SDA LINE R A / C WK A C K A C K A C K N O A C K Serial Number Read: Reading the serial number is similar to the sequential read sequence but requires use of the device address seen in Table 8-1 on page 10, a dummy write, and the use of a 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 regular EEPROM array and the serial number block, a dummy write sequence, as part of a Random Read or Sequential Read protocol, should be performed to ensure the address pointer is set to zero. A Current Address Read of the serial number block is supported but if the previous operation was to the EEPROM array, the address pointer will retain the last location accessed, incremented by one. Reading the serial number from a location other than the first address of the block will not result in a unique serial number. Additionally, the word address contains a ‘10’ sequence in bit A11 and A10 of the word address, regardless of the intended address as depicted in Table 8-2 on page 10. If a word address other than ‘10’ is used, then the device will output undefined data. Example: If the application desires to read the first byte of the serial number, the word address input would need to be 0800h. When the end of the 128-bit serial number is reached (16 bytes of data), continued reading of the extended memory region will result in an additional 16 bytes of 00h data. Upon reaching the end of the 32-byte extended memory region, 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 a zero (ACK) and instead issues a Stop condition (see Figure 10-4 on page 14).
