Description:
The Microchip Technology Inc. 24AA02E48/
24AA025E48 (24AAXXXE48*) is a 2 Kbit Electrically
Erasable PROM. The device is organized as two
blocks of 128 x 8-bit memory with a 2-wire serial inter-
face. Low-voltage design permits operation down to
1.7V, with maximum standby and active currents of
only 1
A
and 1 mA, respectively. The 24AAXXXE48
also has a page write capability for up to 8 bytes of
data (16 bytes on the 24AA025E48). The
24AAXXXE48 is available in the standard 8-pin
SOIC, 5-lead SOT-23, and 6-lead SOT-23 packages.

Not 100% tested. C
B
= total capacitance of one bus line in pF.
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.
The combined T
SP
and V
HYS
specifications are due to new Schmitt Trigger inputs which provide improved
noise spike suppression. This eliminates the need for a
T
I
specification for standard operation.
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 web site
