The first-half of the device incorporates a permanent and a reversible software write protection feature while hardware write protection for the entire array is available via an external pin. Once the permanent software write protection is enabled, by sending a special command to the device, it cannot be reversed. However, the reversible software write protection is enabled and can be reversed by sending a special command. The hardware write protection is controlled with the WP pin and can be used to protect the entire array, whether or not the software write protection has been enabled. This allows the user to protect none, first-half, or all of the array depending on the application. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. The AT34C02B is available in space saving 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire serial interface. It is available in 1.7V (1.7V to 3.6V). 8-ball dBGA2 Table 1.

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 hardwired (directly to GND or to Vcc) for compatibility with other AT24Cxx devices. When the pins are hardwired, as many as eight 2K devices may be addressed on a single bus system. (Device addressing is discussed in detail under “Device Addressing,” page 9.) A device is selected when a corresponding hardware and software match is true. If these pins are left floating, the A2, A1, and A0 pins will be internally pulled down to GND. However, due to capacitive coupling that may appear during customer applications, Atmel recommends always connecting the address pins to a known state. When using a pull-up resistor, Atmel recommends using 10kΩ or less. WRITE PROTECT (WP): The write protect input, when connected to GND, allows normal write operations. When WP is connected directly 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. However, due to capacitive coupling that may appear during customer applications, Atmel recommends always connecting the WP pins to a known state. When using a pull-up resistor, Atmel recommends using 10kΩ or less. Table 2.

Random word addressing requires a 8-bit data word address. 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 4 on page 7). 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 5 on page 8). 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 5 on page 8). 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 AT34C02B features a low-power standby mode which is enabled: (a) upon power-up or (b) after the receipt of the STOP bit and the completion of any internal operations. MEMORY RESET: After an interruption in protocol, power loss or system reset, any Two-wire part can be reset by following these steps: (a) Clock up to 9 cycles, (b) look for SDA high in each cycle while SCL is high and then (c) create a start condition. 6 AT34C02B 3417E–SEEPR–1/07 AT34C02B Figure 2.

Output Acknowledge 8 AT34C02B 3417E–SEEPR–1/07 AT34C02B Device Addressing The 2K EEPROM device requires an 8-bit device address word following a start condition to enable the chip for a read or write operation (see Figure 10 on page 13). The device address word consists of a mandatory one-zero sequence for the first four most-significant bits (1010) for normal read and write operations and 0110 for writing to the write protect register. The next 3 bits are the A2, A1 and A0 device address bits for the AT34C02B EEPROM. These 3 bits must compare to their corresponding hard-wired input pins. 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. The device will not acknowledge if the write protect register has been programmed and the control code is 0110. 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, t WR , 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 11 on page 13). The device will acknowledge a write command, but not write the data, if the software or hardware write protection has been enabled. The write cycle time must be observed even when the write protection is enabled. PAGE WRITE: The 2K device is capable of 16-byte page write. 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 fifteen 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 (see Figure 12 on page 14). 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 word address, internally generated, reaches the page boundary, the following byte is 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 previous data will be overwritten. The address “roll over” during write is from the last byte of the current page to the first byte of the same page. The device will acknowledge a write command, but not write the data, if the software or hardware write protection has been enabled. The write cycle time must be observed even when the write protection is enabled. 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 read or write sequence to continue. 9 3417E–SEEPR–1/07 Write Protection The software write protection, once enabled, write protects only the first-half of the array (00H - 7FH) while the hardware write protection, via the WP pin, is used to protect the entire array. PERMANENT SOFTWARE WRITE PROTECTION: The software write protection is enabled by sending a command, similar to a normal write command, to the device which programs the permanent write protect register. This must be done with the WP pin low. The write protect register is programmed by sending a write command with the device address of 0110 instead of 1010 with the address and data bit being don’t cares (see Figure 7 on page 10). Once the software write protection has been enabled, the device will no longer acknowledge the 0110 control byte. The software write protection cannot be reversed even if the device is powered down. The write cycle time must be observed. REVERSIBLE SOFTWARE WRITE PROTECTION: The reversible software write protection is enabled by sending a command, similar to a normal write command, to the device which programs the reversible write protect register. This must be done with the WP pin low. The write protect register is programmed by sending a write command 01100010 with pins A2 and A1 tied to ground or don't connect and pin A0 connected to VHV (see Figure 8). The reversible write protection can be reversed by sending a command 01100110 with pin A2 tied to ground or no connect, pin A1 tied to VCC and pin A0 tied to VHV (see Figure 9). HARDWARE WRITE PROTECTION: The WP pin can be connected to VCC, GND, or left floating. Connecting the WP pin to VCC will write protect the entire array, regardless of whether or not the software write protection has been enabled. The software write protection register cannot be programmed when the WP pin is connected to VCC. If the WP pin is connected to GND or left floating, the write protection mode is determined by the status of the software write protect register. Figure 7.

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 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. 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 an input zero but does generate a following stop condition (see Figure 13 on page 14). 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 12 AT34C02B 3417E–SEEPR–1/07 AT34C02B does not respond with a zero but does generate a following stop condition (see Figure 14 on page 14). 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 15 on page 14). PERMANENT WRITE PROTECT REGISTER (PSWP) STATUS: To find out if the register has been programmed, the same procedure is used as to program the register except that the R/W bit is set to 1. If the device sends an acknowledge, then the permanent write protect register has not been programmed. Otherwise, it has been programmed and the device is permanently write protected at the first half of the array. Table 10.
