Note 1: Not 100% tested. C
B = total capacitance of one bus line in pF.
2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
3: The combined T
SP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved
noise spike suppression. This eliminates the need for a
TI specification for standard operation.
4: This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ Model which can be obtained from Microchip’s website
at www.microchip.com.

2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1: PIN FUNCTION TABLE
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 V
CC (typical 10 k for 100 kHz, 2 k 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 A0, A1, A2 Chip Address Inputs
The A0, A1 and A2 pins are not used by the
24AA02E48/24AA02E64. They may be left floating or
tied to either V
SS or VCC.
For the 24AA025E48/24AA025E64, the levels on the
A0, A1 and A2 inputs are compared with the
corresponding bits in the slave address. The chip is
selected if the compare is true. For the 6-lead SOT-23
package, pin A2 is not connected and its corresponding
bit in the slave address should always be set to ‘0’.
Up to eight 24AA025E48/24AA025E64 devices (four
for the SOT-23 package) may be connected to the
same bus by using different Chip Select bit
combinations. These inputs must be connected to
either V
SS or VCC.
