DESCRIPTION
The Microchip Technology Inc. 24LC024/24LC025 is a
2K bit Serial Electrically Erasable PROM with a voltage
range of 2.5V to 5.5V. 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 10
碌
A and 1
mA 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 24LC024/24LC025
devices on the same bus for up to 16K bits of contigu-
ous EEPROM memory. The device is available in the
standard 8-pin PDIP, 8-pin SOIC (150 mil), and TSSOP
packages.
*WP pin available only on 24LC024. This
pin has no internal connection on 24LC025
