... Description: Temp. The Microchip Technology Inc. 24AA02/24LC02B Ranges (24XX02 Kbit Electrically Erasable PROM. The device is organized as one block of 256 x 8-bit memory I with a 2-wire serial interface. Low-voltage design I, E permits operation down to 1.7V, with standby and active currents of only 1 μA and 1 mA, respectively. ...

FUNCTIONAL DESCRIPTION The 24XX02 supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, while a device receiving data is defined as a receiver. The bus has ...

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 ‘ binary for read and ...

... However, instead of generating a Stop condition, the master transmits data bytes to the 24XX02, 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 ‘ ...

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 ...

... To provide sequential reads, the 24XX02 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 the 8.4 ...
