Description:
The Microchip Technology Inc. 24VL024/24VL025 is a
2 Kbit Serial Electrically Erasable PROM with
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 EEPROM memory. The device is
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.
