Description:
The Microchip Technology Inc. 24AA02/24LC02B
(24XX02*) is a 2 Kbit Electrically Erasable PROM. The
device is organized as one block of 256 x 8-bit memory
with a 2-wire serial interface. Low-voltage design
permits operation down to 1.7V, with standby and
active currents of only 1 A and 1 mA, respectively.
The 24XX02 also has a page write capability for up to
8 bytes of data. The 24XX02 is available in the
standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3
DFN and MSOP packages and is also available in the
5-lead SOT-23 package.

SCL SDA Start Condition © 2007 Microchip Technology Inc. 24AA02/24LC02B 3.4 Data Valid (D) 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 ...

... Device Addressing A control byte is the first byte received following the Start condition from the master device. The control byte consists of a four-bit control code. For the 24XX02, this is set as ‘ 1010’ binary for read and write operations. The next three bits of the control byte are “don’t cares” ...

... Block Select Bits x = don’t care © 2007 Microchip Technology Inc. 24AA02/24LC02B master has transmitted a Stop condition. Upon receipt of each word, the four lower-order Address Pointer bits are internally incremented by ‘ bits of the word address remain constant. If the master should transmit more than 8 words prior to generating the Stop condition, the address counter will roll over and the previously received data will be overwritten ...

Page 8

... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). 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 directs the 24XX02 to transmit the next sequentially- addressed 8-bit word (Figure 7-3) ...
