Programming operations are allowed if WP pin is left un-connected or input to VIL. Conversely all programming functions are disabled if WP pin is connected to VIH or VCC. Read operations is not affected by the WP pin’s input level. If left unconnected, it is internally recognized as VIL. However, due to capacitive coupling that may appear in customer applications, recommends always connecting the WP pin to a known state. When using a pull-up or pull-down resistor, recommends using 10kΩ or less. MEMORY ORGANIZATION The 24C16devices have 128 pages. Since each page has 16 bytes, random word addressing to 24C16 will require 11 bits data word addresses. DEVICE OPERATION (A) SERIAL CLOCK AND DATA TRANSITIONS The SDA pin is typically pulled to high by an external resistor. Data is allowed to change only when Serial clock SCL is at VIL. Any SDA signal transition may interpret as either a START or STOP condition as described below. (B) START CONDITION With SCL ≥ VIH, a SDA transition from high to low is interpreted as a START condition. All valid commands must begin with a START condition. (C) STOP CONDITION With SCL ≥ VIH, a SDA transition from low to high is interpreted as a STOP condition. All valid read or write commands end with a STOP condition. The device goes into the STANDBY mode if it is after a read command. A STOP condition after page or byte write command will trigger the chip into the STANDBY mode after the self timed internal programming finish. (D) ACKNOWLEDGE The 2-wire protocol transmits address and data to and from the EEPROM in 8 bit words. The EEPROM acknowledges the data or address by outputting a "0" after receiving each word. The ACKNOWLEDGE signal occurs on the 9th serial clock after each word. (E) STANDBY MODE The EEPROM goes into low power STANDBY mode after a fresh power up, after receiving a STOP bit in read mode, or after completing a self-time internal programming operation. (F) SOFT RESET After an interruption in protocol power loss or system reset, any two-wire part can be reset by following these steps: 1.

The first four most significant bits of the device address must be 1010, which is common to all serial EEPROM devices. The next three bits are device address bits. These three device address bits (5th) are to match with the external chip select/address pin states. If a match is made, the EEPROM device outputs an ACKNOWLEDGE signal after the 8th read/write bit, otherwise the chip will go into STANDBY mode. The last or 8th bit is a read/write command bit. If the 8th bit is at VIH then the chip goes into read mode. If a “0” is detected, the device enters programming mode. 24C16 does not use any device address bit. Only one 24C16 device can be used on the on 2-wire bus. WRITE OPERATIONS (A) BYTE WRITE A byte write operation starts when a micro-controller sends a START bit condition, follows by a proper EEPROM device address and then a write command. If the device address bits match the chip select address, the EEPROM device will acknowledge at the 9th clock cycle. The micro-controller will then send the rest of the lower 8 bits word address. At the 18th cycle, the EEPROM will acknowledge the 8-bit address word. The micro- controller will then transmit the 8 bit data. Following an ACKNOWLDEGE signal from the EEPROM at the 27 th clock cycle, the micro-controller will issue a STOP bit. After receiving the STOP bit, the EEPROM will go into a self-timed programming mode during which all external inputs will be disabled. After a programming time of TWC, the byte programming will finish and the EEPROM device will return to the STANDBY mode. (B) PAGE WRITE A page write is similar to a byte write with the exception that one to sixteen bytes can be programmed along the same page or memory row. All 24C16are organized to have 16 bytes per memory row or page. With the same write command as the byte write, the micro-controller does not issue a STOP bit after sending the 1st byte data and receiving the ACKNOWLEDGE signal from the EEPROM on the 27 th clock cycle. Instead it sends out a second 8-bit data word, with the EEPROM acknowledging at the 36th cycle. This data sending and EEPROM acknowledging cycle repeats until the micro-controller sends a STOP bit after the n × 9th clock cycle. After which the EEPROM device will go into a self-timed partial or full page programming mode. After the page programming completes after a time of TWC, the devices will return to the STANDBY mode. The least significant 4 bits of the word address (column address) increments internally by one after receiving each data word. The rest of the word address bits (row address) do not change internally, but pointing to a specific memory row or page to be programmed. The first page write data word can be of any column address. Up to 16 data words can be loaded into a page. If more then 16 data words are loaded, the 17th data word will be loaded to the 1st data word column address. The 18th data word will be loaded to the 2nd data word column address and so on. In other word, data word address (column address) will “roll” over the previously loaded data.

By issuing a valid read or write address command, the EEPROM will not acknowledge at the 9th clock cycle if the device is still in the self-timed programming mode. However, if the programming completes and the chip has returned to the STANDBY mode, the device will return a valid ACKNOWLEDGE signal at the 9th clock cycle. READ OPERATIONS The read command is similar to the write command except the 8th read/write bit in address word is set to “1”. The three read operation modes are described as follows: (A) CURRENT ADDRESS READ The EEPROM internal address word counter maintains the last read or write address plus one if the power supply to the device has not been cut off. To initiate a current address read operation, the micro-controller issues a START bit and a valid device address word with the read/write bit (8th ) set to “1”. The EEPROM will response with an ACKNOWLEDGE signal on the 9th serial clock cycle. An 8-bit data word will then be serially clocked out. The internal address word counter will then automatically increase by one. For current address read the micro-controller will not issue an ACKNOWLEDGE signal on the 18th clock cycle. The micro-controller issues a valid STOP bit after the 18th clock cycle to terminate the read operation. The device then returns to STANDBY mode. (B) SEQUENTIAL READ The sequential read is very similar to current address read. The micro-controller issues a START bit and a valid device address word with read/write bit (8th ) set to “1”. The EEPROM will response with an ACKNOWLEDGE signal on the 9th serial clock cycle. An 8-bit data word will then be serially clocked out. Meanwhile the internally address word counter will then automatically increase by one. Unlike current address read, the micro-controller sends an ACKNOWLEDGE signal on the 18th clock cycle signaling the EEPROM device that it wants another byte of data. Upon receiving the ACKNOWLEDGE signal, the EEPROM will serially clocked out an 8-bit data word based on the incremented internal address counter. If the micro-controller needs another data, it sends out an ACKNOWLEDGE signal on the 27th clock cycle. Another 8-bit data word will then be serially clocked out. This sequential read continues as long as the micro-controller sends an ACKNOWLEDGE signal after receiving a new data word. When the internal address counter reaches its maximum valid address, it rolls over to the beginning of the memory array address. Similar to current address read, the micro-controller can terminate the sequential read by not acknowledging the last data word received, but sending a STOP bit afterwards instead. (C) RANDOM READ Random read is a two-steps process. The first step is to initialize the internal address counter with a target read address using a “dummy write” instruction. The second step is a current address read.

The EEPROM will then acknowledge. The micro-controller will then send the address word. Again the EEPROM will acknowledge. Instead of sending a valid written data to the EEPROM, the micro-controller performs a current address read instruction to read the data. Note that once a START bit is issued, the EEPROM will reset the internal programming process and continue to execute the new instruction - which is to read the current address.

A decoupling cap should be connected to the VCC PAD which is no smaller than 10nF. (B)Device Reset To prevent inadvertent write operations or any other spurious events from occurring during a power-up sequence, this device includes a Power-on Reset (POR) circuit. Upon power-up, the device will not respond to any commands until the VCC level crosses the internal voltage threshold (VPOR) that brings the device out of Reset and into Standby mode. The system designer must ensure the instructions are not sent to the device until the VCC supply has reached a stable value greater than or equal to the minimum VCC level.
