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 indi-
vidual system. Low current design permits operation
with typical standby and active currents of only 10 A
and 1 mA respectively. The device has a page-write
capability for up to 16 bytes of data. The device is avail-
able in the standard 8-pin PDIP, SOIC (150 mil), and
TSSOP packages.
