Description:
The Microchip Technology Inc. 24AA024H/24LC024H is
a 2 Kbit Serial Electrically Erasable PROM with
operation down to 1.7V. The device is organized as a
single block of 256 x 8-bit memory with a 2-wire serial
interface. Low-current design permits operation with
maximum standby and active currents of only 1 μA and
400 μA, respectively. The device has a page write
capability for up to 16 bytes of data. Functional address
lines allow the connection of up to eight 24AA024H/
24LC024H devices on the same bus for up to 16 Kbits
of contiguous EEPROM memory. The device is
available in the standard 8-pin PDIP, 8-pin SOIC (150
mil), TSSOP, 2x3 TDFN and MSOP packages.

Note 1: Not 100% tested. CB = 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 suppres-
sion. This eliminates the need for a T
I 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 web site at www.microchip.com.
