CB = total capacitance of one bus line in pF. As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions. The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation. This parameter is not tested but ensured by characterization.

Since it is an open-drain terminal, the SDA bus requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz). For normal data transfer, SDA is allowed to change only during SCL low. Changes during SCL high are reserved for indicating Start and Stop conditions. 2.2 Serial Clock (SCL) Description 2.3 Write-Protect (WP) The WP pin must be connected to either VSS or VCC. If tied to VSS, normal memory operation is enabled (read/write the entire memory 000-7FF). If tied to VCC, write operations are inhibited. The entire memory will be write-protected. Read operations are not affected. 2.4 A0, A1, A2 The A0, A1 and A2 pins are not used by the 24LC16B. They may be left floating or tied to either VSS or VCC. The SCL input is used to synchronize the data transfer to and from the device. 2009-2016 Microchip Technology Inc. DS20002213B-page 5 24LC16B 3.0 FUNCTIONAL DESCRIPTION The 24LC16B supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as a transmitter, while a device receiving data is defined as a receiver. The bus has to be controlled by a master device which generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24LC16B works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated. 4.0 BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition. Accordingly, the following bus conditions have been defined (Figure 4-1). 4.4 The state of the data line represents valid data when, after a Start condition, the data line is stable for the duration of the high period of the clock signal. The data on the line must be changed during the low period of the clock signal. There is one clock pulse per bit of data. Each data transfer is initiated with a Start condition and terminated with a Stop condition. The number of data bytes transferred between Start and Stop conditions is determined by the master device and is, theoretically, unlimited (although only the last sixteen will be stored when doing a write operation). When an overwrite does occur it will replace data in a first-in first-out (FIFO) fashion. 4.5 Bus Not Busy (A) Both data and clock lines remain high. 4.2 Start Data Transfer (B) A high-to-low transition of the SDA line while the clock (SCL) is high determines a Start condition. All commands must be preceded by a Start condition. 4.3 Stop Data Transfer (C) A low-to-high transition of the SDA line while the clock (SCL) is high determines a Stop condition. All operations must end with a Stop condition. FIGURE 4-1: (A) Acknowledge Each receiving device, when addressed, is obliged to generate an Acknowledge signal after the reception of each byte. The master device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: 4.1 Data Valid (D) The 24LC16B does not generate any Acknowledge bits if an internal programming cycle is in progress. The device that acknowledges must pull down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable-low during the high period of the acknowledge-related clock pulse. Of course, setup and hold times must be taken into account. During reads, a master must signal an end of data to the slave by not generating an Acknowledge bit on the last byte that has been clocked out of the slave. In this case, the slave (24LC16B) will leave the data line high to enable the master to generate the Stop condition.

The control byte consists of a four-bit control code. For the 24LC16B, this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Block Select bits (B2, B1, B0). They are used by the master device to select which of the eight 256 word-blocks of memory are to be accessed. These bits are, in effect, the three Most Significant bits (MSb) of the word address. It should be noted that the protocol limits the size of the memory to eight blocks of 256 words, therefore, the protocol can support only one 24LC16B per system. The last bit of the Control byte defines the operation to be performed. When set to ‘1’, a read operation is selected. When set to ‘0’, a write operation is selected. Following the Start condition, the 24LC16B monitors the SDA bus, checking the device type identifier being transmitted and, upon receiving a ‘1010’ code, the slave device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24LC16B will select a read or write operation.

This indicates to the addressed slave receiver that a byte with a word address will follow once it has generated an Acknowledge bit during the ninth clock cycle. Therefore, the next byte transmitted by the master is the word address and will be written into the Address Pointer of the 24LC16B. After receiving another Acknowledge signal from the 24LC16B, the master device will transmit the data word to be written into the addressed memory location. The 24LC16B acknowledges again and the master generates a Stop condition. This initiates the internal write cycle and, during this time, the 24LC16B will not generate Acknowledge signals (Figure 6-1). Note: 6.2 When doing a write of less than 16 bytes, the data in the rest of the page is refreshed along with the data bytes being written. This will force the entire page to endure a write cycle; for this reason, endurance is specified per page. Note: 6.3 Page write operations are limited to writing bytes within a single physical page, regardless of the number of bytes actually being written. Physical page boundaries start at addresses that are integer multiples of the page buffer size (or ‘page-size’) and end at addresses that are integer multiples of [page size – 1]. If a Page Write command attempts to write across a physical page boundary, the result is that the data wraps around to the beginning of the current page (overwriting data previously stored there), instead of being written to the next page, as might be expected. It is therefore necessary for the application software to prevent page write operations that would attempt to cross a page boundary. Write Protection The WP pin allows the user to write-protect the entire array (000-7FF) when the pin is tied to VCC. If tied to VSS, the write protection is disabled. Page Write The write control byte, word address and the first data byte are transmitted to the 24LC16B in the same way as in a byte write. However, instead of generating a Stop condition, the master transmits up to 16 data bytes to the 24LC16B, which are temporarily stored in the on-chip page buffer and will be written into memory once the master has transmitted a Stop condition. Upon receipt of each word, the four lower-order Address Pointer bits are internally incremented by one. The higher-order 7 bits of the word address remain constant. If the master should transmit more than 16 bytes prior to generating the Stop condition, the address counter will roll over and the previously received data will be overwritten. As with the byte write operation, once the Stop condition is received an internal write cycle will begin (Figure 6-2).

Once the Stop condition for a Write command has been issued from the master, the device initiates the internally-timed write cycle and ACK polling can then be initiated immediately. This involves the master sending a Start condition followed by the control byte for a Write command (R/W = 0). If the device is still busy with the write cycle, no ACK will be returned. If the cycle is complete, the device will return the ACK and the master can then proceed with the next Read or Write command. See Figure 7-1 for a flow diagram of this operation. FIGURE 7-1: ACKNOWLEDGE POLLING FLOW Send Write Command Send Stop Condition to Initiate Write Cycle Send Start Send Control Byte with R/W = 0 Did Device Acknowledge (ACK = 0)? No Yes Next Operation DS20002213B-page 10 2009-2016 Microchip Technology Inc. 24LC16B 8.0 READ OPERATION Read operations are initiated in the same way as write operations, with the exception that the R/W bit of the slave address is set to ‘1’. There are three basic types of read operations: current address read, random read and sequential read. 8.1 8.4 Noise Protection The 24LC16B employs a VCC threshold detector circuit which disables the internal erase/write logic if the Vcc is below 1.5V at nominal conditions. The SCL and SDA inputs have Schmitt Trigger and filter circuits which suppress noise spikes to assure proper device operation, even on a noisy bus. Current Address Read The 24LC16B contains an address counter that maintains the address of the last word accessed, internally incremented by one. Therefore, if the previous access (either a read or write operation) was to address ‘n’, the next current address read operation would access data from address n + 1. Upon receipt of the slave address with R/W bit set to ‘1’, the 24LC16B issues an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the 24LC16B discontinues transmission (Figure 8-1). 8.2 Random Read Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, the word address must first be set. This is accomplished by sending the word address to the 24LC16B as part of a write operation. Once the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the internal Address Pointer is set. The master then issues the control byte again, but with the R/W bit set to a ‘1’. The 24LC16B will then issue an acknowledge and transmit the 8-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the 24LC16B will discontinue transmission (Figure 8-2). 8.3 Sequential Read Sequential reads are initiated in the same way as a random read, except that once the 24LC16B transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24LC16B to transmit the next sequentially addressed 8-bit word (Figure 8-3). To provide sequential reads, the 24LC16B contains an internal Address Pointer that is incremented by one upon completion of each operation. This Address Pointer allows the entire memory contents to be serially read during one operation. 2009-2016 Microchip Technology Inc.
