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.
