Description:
The Microchip Technology Inc. 24AA04/24LC04B (24XX04*) is a 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 A and 1 mA, respectively. The 24XX04 also has a page write capability for up to 16 bytes of data. The 24XX04 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages and is also available in the 5-lead SOT-23 package.

100 kHz for VCC <2.5V

Features:
Single supply with operation down to 1.7V for 24AA04 devices, 2.5V for 24LC04B devices Low-power CMOS technology: - Read current 1 mA, typical - Standby current 1 A, typical 2-wire serial interface, I2CTM compatible Schmitt Trigger inputs for noise suppression Output slope control to eliminate ground bounce 100 kHz and 400 kHz clock compatibility Page write time 3 ms, typical Self-timed erase/write cycle 16-byte page write buffer Hardware write-protect ESD protection >4,000V More than 1 million erase/write cycles Data retention >200 years Factory programming available Packages include 8-lead PDIP, SOIC, TSSOP, DFN, MSOP and 5-lead SOT-23 Pb-free and RoHS compliant Temperature ranges: - Industrial (I): -40 C to +85 C - Automotive (E): -40 C to +125 C
