24LC512 is a 64K x 8 (512 Kbit) Serial Electrically Erasable PROM (EEPROMs), from Microchip Technology Inc. (see the product page). It has been developed for advanced, low-power applications such as personal communications and data acquisition. This device also has a page write capability of up to 128 bytes of data.
This device is capable of both random and sequential reads up to the 512K boundary. Functional address lines allow up to eight devices on the same bus, for up to 4 Mbit address space.
This is an example how to interface 24XXX EEPROMs with 8051. I use SDCC as C Compiler. My schematic is shown below.
