DESCRIPTION
The Microchip Technology Inc. 24LCS61/62 is a 1K/2K
bit Serial EEPROM developed for applications that
require many devices on the same bus but do not have
the I/O pins required to address each one individually.
These devices contain an 8 bit address register that is
set upon power-up and allows the connection of up to
255 devices on the same bus. When the process of
assigning ID values to each device is in progress, the
device will automatically handle bus arbitration if more
than one device is operating on the bus. In addition, an
external open drain output pin is available that can be
used to enable other circuitry associated with each
individual system. Low current design permits opera-
tion with typical standby and active currents of only
10 µA and 1 mA respectively. The device has a page-
write capability for up to 16 bytes of data. The device is
available in the standard 8-pin PDIP, SOIC (150 mil),
and TSSOP packages.

3.5 Acknowledge
Each receiving device, when addressed, is required to
generate an acknowledge after the reception of each
byte. The master device must generate an extra clock
pulse which is associated with this acknowledge bit.
Note:
The 24LCS61/62 does not generate any
acknowledge bits if an internal program-
ming cycle is in progress.
FIGURE 3-2: ACKNOWLEDGE TIMING
The device that acknowledges has to pull down the
SDA line during the acknowledge clock pulse in such a
way that the SDA line is stable LOW during the HIGH
period of the acknowledge related clock pulse. Of
course, setup and hold times must be taken into
account. A master must signal an end of data to the
slave by not generating an acknowledge bit on the last
byte that has been clocked out of the slave. In this case,
the slave must leave the data line HIGH to enable the
master to generate the STOP condition (Figure 3-2).

SDA
Data from transmitter
Transmitter must release the SDA line at this point
allowing the Receiver to pull the SDA line low to
acknowledge the previous eight bits of data.
Data from transmitter
Receiver must release the SDA line at this point
so the Transmitter can continue sending data.
