24VL024/24VL025 2 2K I C Serial EEPROM Device Selection Table Description: The Microchip Technology Inc. 24VL024/24VL025 is a Part Number VCC Range Max Clock 2Kbit Serial Electrically Erasable PROM with (1) 24VL024 1.5 to 3.6V 400 kHz operation down to 1.5V. The device is organized as a single block of 256 x 8-bit memory with a 2-wire serial (1) 24VL025 1.5 to 3.6V 400 kHz interface. Low-current design permits operation with maximum standby and active currents of only 1 A and Note 1: 100 kHz for VCC < 1.8V 400 A, respectively. The device has a page write capability for up to 16 bytes of data. Functional address Features: lines allow the connection of up to eight 24VL024/ 24VL025 devices on the same bus for up to 16 Kbits of Single-Supply with Operation down to 1.5V contiguous EEPROM memory. The device is Low-Power CMOS Technology: available in the standard 8-pin PDIP, 8-pin SOIC (150 - 400 A active current, maximum mil), TSSOP, 2x3 TDFN and MSOP packages. The -1 A standby current, maximum 24VL025 is also available in the 6-lead, SOT-23 2 2-Wire Serial Interface Bus, I C Compatible package.
