Description:

The Microchip Technology Inc. 24AA64F/24LC64F

(24XX64F*) is a 64 Kbit Electrically Erasable PROM.

The device is organized as a single block of 8K x 8-bit

memory with a 2-wire serial interface. Low-voltage

design permits operation down to 1.7V, with standby

and read currents of only 1 μA and 400 μA,

respectively. It has been developed for advanced, low-

power applications such as personal communications

or data acquisition. The 24XX64F also has a page

write capability for up to 32 bytes of data. Functional

address lines allow up to eight devices on the same

bus, for up to 512 Kbits address space. The 24XX64F

is available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, TDFN and MSOP packages. The

24XX64F is also available in the 5-lead SOT-23

package.

... WRITE OPERATIONS 6.1 Byte Write Following the Start condition from the master, the control code (four bits), the Chip Select (three bits) and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. This indicates to the addressed slave receiver that the address high byte 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 ...
