Description:
The Microchip Technology Inc. 24AA02/24LC02B
(24XX02*) is a 2 Kbit Electrically Erasable PROM. The
device is organized as one block 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 24XX02 also has a page write capability for up to
8 bytes of data. The 24XX02 is available in the
standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3
DFN, 2x3 TDFN and MSOP packages and is also avail-
able in the 5-lead SOT-23 and SC-70 packages.

Supply
2.1 Serial Address/Data Input/Output
(SDA)
SDA is a bidirectional pin used to transfer addresses
and data into and out of the device. Since it is an open-
drain terminal, the SDA bus requires a pull-up resistor
to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating Start and Stop conditions.
2.2 Serial Clock (SCL)
The SCL input is used to synchronize the data transfer
to and from the device.
2.3 Write-Protect (WP)
The WP pin must be connected to either VSS or VCC.
If tied to VSS, normal memory operation is enabled
(read/write the entire memory 00-FF).
If tied to VCC, write operations are inhibited. The entire
memory will be write-protected. Read operations are
not affected.
2.4 A0, A1, A2
These A0, A1 and A2 pins are not used by the 24XX02.
They may be left floating or tied to either VSS or VCC.
