Description:
The Microchip Technology Inc. 24AA04H/24LC04BH
(24XX04H*) is an 4 Kbit Electrically Erasable PROM.
The device is organized as two blocks 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 24XX04H also has a page write
capability for up to 16 bytes of data. The 24XX04H is
available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP, 2x3 TDFN and MSOP packages, and
is also available in the 5-lead SOT-23 package. All
packages are Pb-free and RoHS compliant.

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 on Microchip’s web site at
