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. Figure 6-1. 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 condition will place the EEPROM in a standby power mode. Figure 6-2.

The EEPROM sends a zero to acknowledge that it has received each word. When the EEPROM is reading data out, the host will transmit an ACK after each data word to indicate that the next word can be transmitted.This happens during the ninth clock cycle. Figure 6-3.

Create a Start condition (if possible). 2. 3. Clock nine cycles. Create another Start condition followed by Stop condition as shown in the following figures. 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 6-4.

Device Addressing The 1K/2K/4K/8K EEPROM devices require an 8-bit device address word following a Start condition to enable the device for a read or write operation. The device address word consists of a mandatory '1010' sequence for the first four Most Significant Bits (MSB). This is common to all the Serial EEPROM devices. For the 1K/2K EEPROM, the next three bits are the A2, A1, and A0 device address bits. These three bits must compare to their corresponding hardwired input A2, A1, and A0 pins. The 4K EEPROM only uses the A2 and A1 device address bits with the A0 bit being a memory address bit (P0). The two device address bits must compare to their corresponding hardwired input A2 and A1 pins. The A0 pin is not connected. The 8K EEPROM only uses the A2 device address bit with the next two bits (P1, P0) being for memory page addressing. The A2 bit must compare to its corresponding hardwired input pin. The A1 and A0 pins 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. After a valid comparison of the device address, the EEPROM will output a zero. If the comparison is invalid, the device will return to a standby state.

Write Operations Byte Write: A write operation requires an 8-bit data 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. Figure 8-1. Byte Write S T A R T W R I T E Device Address Word Address S T O P Data SDA Line M S B L R A S / C BW K M S B L A SC BK A C K * = Don't care bit for 1K Page Write: The 1K/2K EEPROM are capable of an 8-byte Page Write. The 4K/8K EEPROM devices are capable of 16-byte Page Writes. A Page Write is initiated the same 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 seven (1K/2K) or fifteen (4K/ 8K) more 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. The data Word Address lower three (1K/2K) or four (4K/8K) 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 Word Address, internally generated, reaches the page boundary, the next byte sent will be written to the beginning address on the same page. In order words, if more than eight (1K/2K) or sixteen (4K/8K) data words are transmitted to the EEPROM, the data Word Address will "roll over" and the data previously sent to the device at the beginning of the page write sequence will be altered.

This involves sending a Start condition followed by the device address word. The read/write bit state is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM respond with a zero, allowing the read or write sequence to continue. 12 AT24C01C/02C/04C/08C Automotive [DATASHEET] Atmel-8819C-SEEPROM-AT24C01C-02C-04C-08C-Auto-Datasheet_092016 9. 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 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 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. To end the command, the microcontroller does not respond with a zero but does generate a Stop condition in the subsequent clock cycle. Figure 9-1. Current Address Read S T A R T R E A D Device Address S T O P Data SDA Line M S B N O L R A S / C B WK 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. To end the command, the microcontroller does not respond with a zero but does generate a Stop condition in the subsequent clock cycle. Figure 9-2.

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. To end the command, the microcontroller does not respond with a zero but does generate a Stop condition in the subsequent clock cycle. Figure 9-3.
