Description:
The Microchip Technology Inc. 24VL024H 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 typical
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 24VL024H 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.
