DS28EC20+ Description

Short technical summary and product information.

The DS28EC20+ from Analog Devices is a 20480-bit nonvolatile EEPROM, organized as 80 memory pages of 256 bits each, plus a control page. Data is written to a 32-byte scratchpad for verification before being copied to EEPROM memory. This device utilizes the single-conductor 1-Wire bus for communication, with each unit possessing a unique 64-bit ROM registration number for addressing in multidrop environments.

 

Key features include individual 8-page groups that can be permanently write-protected or set to EPROM-Emulation mode. It offers backward compatibility with legacy devices and boasts a 200k write/erase cycle endurance at +25°C. The DS28EC20+ operates over a wide temperature range of -40°C to +85°C and is housed in a low-cost TO-92 package, making it suitable for applications such as device authentication, sensor TEDS, and PCB identification.
