Description:

The Microchip Technology Inc. 24AA16/24LC16B

(24XX16*) is a 16 Kbit Electrically Erasable PROM.

The device is organized as eight blocks 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 μA and 1 mA,

respectively. The 24XX16 also has a page write

capability for up to 16 bytes of data. The 24XX16 is

available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, 2x3 DFN, 2x3 TDFN and MSOP pack-

ages, and is also available in the 5-lead SOT-23, and

Chip Scale packages.

... FUNCTIONAL DESCRIPTION The 24XX16 supports a bidirectional, 2-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 master device which generates the ...

... WRITE OPERATION 6.1 Byte Write Following the Start condition from the master, the device code (4 bits), the block address (3 bits) and the R/W bit, which is a logic-low, is placed onto the bus by the master transmitter. This indicates to the addressed slave receiver that a byte with a word address will follow once it has generated an Acknowledge bit during the ninth clock cycle ...

... 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 ...
