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.

The SCL input is used to synchronize the data transfer to and from the device. 2.2 2.4 Serial Address/Data Input/Output (SDA) The SDA input is a bidirectional pin used to transfer addresses and data into and out of the device. Since it is an open-drain terminal, the SDA bus requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ 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. DS20002084C-page 6 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 000-03FF). If tied to VCC, write operations are inhibited, half of the memory will be write-protected (200h-3FFh). Read operations are not affected.  2008-2021 Microchip Technology Inc. 24AA08H/24LC08BH 3.0 FUNCTIONAL DESCRIPTION The 24XX08H supports a bidirectional, two-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 host device which generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24XX08H works as client. Both host and client can operate as transmitter or receiver, but the host 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). 4.1 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 the data bytes transferred between the Start and Stop conditions is determined by the host 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) principle. 4.5 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 be ended with a Stop condition. FIGURE 4-1: SCL (A) Acknowledge Each receiving device, when addressed, is obliged to generate an Acknowledge after the reception of each byte. The host device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: Bus Not Busy (A) Data Valid (D) The 24XX08H does not generate any Acknowledge bits if an internal programming cycle is in progress. The device that acknowledges has to 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. Moreover, setup and hold times must be taken into account. During reads, a host must signal an end of data to the client by not generating an Acknowledge bit on the last byte that has been clocked out of the client. In this case, the client (24XX08H) will leave the data line high to enable the host to generate the Stop condition.

The control byte consists of a four-bit control code. For the 24XX08H, this is set as ‘1010’ binary for read and write operations. The next bit of the control byte is a “don’t care” for the 24XX08H. The last two bits, B1 and B0, are used by the host device to select which of the four 256-word blocks of memory are to be accessed. These bits, in effect, are the Most Significant bits of the word address. The combination of the 4-bit control code and the next three bits are called the client address. The last bit of the control byte is the Read/Write (R/W) bit and it 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 24XX08H monitors the SDA bus, checking the device type identifier being transmitted. Upon receiving a valid client address and the R/W bit, the client device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24XX08H will select a read or write operation.

If the host should transmit more than 16 words prior to generating the Stop condition, the Address Pointer 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). Following the Start condition from the host, the device code (4 bits), the block address (3 bits) and the R/W bit, which is a logic-low, are placed onto the bus by the host transmitter. This indicates to the addressed client 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 host is the word address and will be written into the Address Pointer of the 24XX08H. After receiving another Acknowledge signal from the 24XX08H, the host device will transmit the data word to be written into the addressed memory location. The 24XX08H acknowledges again and the host generates a Stop condition. This initiates the internal write cycle and, during this time, the 24XX08H will not generate Acknowledge signals (Figure 6-1). 6.2 Note: Page Write The write control byte, word address and the first data byte are transmitted to the 24XX08H in the same way as in a byte write. However, instead of generating a Stop condition, the host transmits up to 16 data bytes to the 24XX08H, which are temporarily stored in the on-chip page buffer and will be written into memory once the host has transmitted a Stop condition. Upon receipt of each word, the four lower-order Address Pointer bits, which form the byte counter, are internally incremented by one. FIGURE 6-1: Write Protection The WP pin allows the user to write-protect half of the array (200h-3FFh) when the pin is tied to VCC. If the pin is tied to VSS, the write protection is disabled.

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.

Once the Stop condition for a write command has been issued from the host, the device initiates the internally-timed write cycle and ACK polling can then be initiated immediately. This involves the host 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 host can then proceed with the next read or write operation. 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 DS20002084C-page 10  2008-2021 Microchip Technology Inc. 24AA08H/24LC08BH 8.0 READ OPERATION 8.3 Sequential Read Read operations are initiated in the same way as write operations, with the exception that the R/W bit of the client address is set to ‘1’. There are three basic types of read operations: current address read, random read and sequential read. Sequential reads are initiated in the same way as a random read, except that once the 24XX08H transmits the first data byte, the host issues an Acknowledge as opposed to a Stop condition in a random read. This directs the 24XX08H to transmit the next sequentially-addressed 8-bit word (Figure 8-3). 8.1 To provide sequential reads, the 24XX08H 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. Current Address Read The 24XX08H contains an Address Pointer 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 client address with R/W bit set to ‘1’, the 24XX08H issues an Acknowledge and transmits the 8-bit data word. The host will not acknowledge the transfer, but does generate a Stop condition and the 24XX08H discontinues transmission (Figure 8-1). 8.2 8.4 Noise Protection 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. Random Read Random read operations allow the host 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 24XX08H as part of a write operation. Once the word address is sent, the host generates a Start condition following the Acknowledge. This terminates the write operation, but not before the internal Address Pointer is set. The host then issues the control byte again, but with the R/W bit set to a ‘1’. The 24XX08H will then issue an Acknowledge and transmit the 8-bit data word. The host will not acknowledge the transfer, but does generate a Stop condition and the 24XX08H will discontinue transmission (Figure 8-2).
