24VL024/24VL025

Description:

The Microchip Technology Inc. 24VL024/24VL025 is a

2 Kbit

operation down to 1.5V. The device is organized as a

single block of 256 x 8-bit memory with a 2-wire serial

interface. Low-current design permits operation with

maximum standby and active currents of only 1 μA and

400 μA, respectively. The device has a page write

capability for up to 16 bytes of data. Functional address

lines allow the connection of up to eight 24VL024/

24VL025 devices on the same bus for up to 16 Kbits of

contiguous

available in the standard 8-pin PDIP, 8-pin SOIC (150

mil), TSSOP, 2x3 TDFN and MSOP packages. The

24VL025 is also available in the 6-lead, SOT-23

package.
