24AA04/24LC04B 2 4K I C Serial EEPROM Device Selection Table Description: Part VCC Max. Clock Temp. The Microchip Technology Inc. 24AA04/24LC04B Number Range Frequency Ranges (24XX04*) is a 4 Kbit Electrically Erasable PROM. The device is organized as two blocks of 256 x 8-bit (1) 24AA04 1.7-5.5 400 kHz I memory with a 2-wire serial interface. Low-voltage 24LC04B 2.5-5.5 400 kHz I, E design permits operation down to 1.7V, with standby Note 1: 100 kHz for VCC <2.5V. and active currents of only 1 A and 1mA, respectively. The 24XX04 also has a page write capability for up to 16 bytes of data. The 24XX04 is Features: available in the standard 8-pin PDIP, surface mount Single Supply with Operation down to 1.7V for SOIC, TSSOP, 2x3 DFN, 2x3 TDFN, and MSOP 24AA04 Devices, 2.5V for 24LC04B Devices packages and is also available in the 5-lead SOT-23, or 4-lead Chip Scale package.
