Description
The Microchip Technology Inc. 24LC09 is an 8 Kbit
Electrically Erasable PROM (EEPROM) designed to
meet the Advanced Communication Riser Special
Interest Group (ACR-SIG). The device is organized as
four blocks of 256 x 8-bit memory that supports the 2-
wire serial interface with a special address: 1011. Low
voltage design permits operation down to 2.5 volts with
typical standby and active currents of only 5 µA and
1 mA, respectively. The 24LC09 also has a page-write
capability for up to 16 bytes of data. The 24LC09 is
available in the standard 8-pin DIP, 8-lead surface
mount SOIC packages.

... Following the start condition, the 24LC09 monitors the SDA bus checking the device type identifier being transmitted, upon a 1011 code the slave device out- puts an acknowledge signal on the SDA line. Depend- ing on the state of the R/W bit, the 24LC09 will select a read or write operation. Control Operation ...

... Then the master issues the control byte again but with the R/W bit set to a one. The 24LC09 will then issue an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer but does generate a stop condition and the 24LC09 discon- tinues transmission (Figure 8-2) ...
