DS2502P-E48+T&R

The DS2502P-E48+T&R is a 48bit node address chip in 6 pin TSOC package. The add-only memory identifies and stores relevant information about the product to which it is associated. This lot or product specific information can be accessed with minimal interface for example, a single port pin of a microcontroller. It is a is a variant of the DS2502 1024bit add-only memory. It differs from the standard DS2502 in its custom ROM family code 89h and the UniqueWare identifier 5E7h in place of the upper 12 bits of the standard ROM serialization field. Data is transferred serially via the 1-wire protocol which requires only a single data lead and a ground return. The entire device can be programmed and then write-protected if desired. Alternatively, the part may be programmed multiple times with new data being appended to, but not overwriting, existing data with each subsequent programming of the device.

• Reads at 2.8V to 6V from -40°C to +85°C and programs at 11.5V to 12V from -40°C to + 50°C
• Factory programmed 48bit node address chip with 768 bits user programmable OTP EPROM
• Provides valid MAC-48/EUI-48 Ethernet address
• Unique, factory lasered and tested 64bit registration number assures absolute traceability
