Description:
The Microchip Technology Inc. 24AA04/24LC04B
(24XX04*) is a 4 Kbit Electrically Erasable PROM. The
device is organized as two blocks of 256 x 8-bit
memory with a 2-wire serial interface. Low-voltage
design permits operation down to 1.8V, with standby
and active currents of only 1 A and 1 mA,
respectively. The 24XX04 also has a page write
capability for up to 16 bytes of data. The 24XX04 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.

... 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).
