... Serial EEPROM Description The Microchip Technology Inc. 24AA01/24LC01B Temp (24XX01 Kbit Electrically Erasable PROM. The Ranges device is organized as one block of 128 x 8-bit memory (1) I with a 2-wire serial interface. Low-voltage design permits operation down to 1.8V with standby and active I, E currents of only 1 A and 1 mA, respectively. The 24XX01 also has a page write capability for bytes of data ...

... However, instead of generating a Stop condition, the master transmits data bytes to the 24XX01, which are temporarily stored in the on-chip page buffer and will be written into the 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 ‘ ...
