Atmel - World's most innovative 2-pin self-powered serial EEPROM (AT21CS01)

Atmel launched the industry’s most innovative Single-Wire EEPROM with only two-pins—a data pin and ground pin for operation—making the new family ideal for the Internet of Things (IoT), wearables, consumable, battery and cable identification markets. The new devices are self-powered, eliminating the need for a power source or Vcc pin, with a parasitic power scheme over the data pin. These devices provide best-in-class ultra-low power standby of 700nA, 200µA for write current, and 80µA for read current at 25 degree Celsius—delivering just one-third of the power of leading competitors. With confined spacing in smaller IoT, wearables, battery and cable identification applications, Atmel’s AT21CS01/11 devices eliminate the need for external capacitors and rectifiers with its parasitic power scheme over a single data pin. Additionally, the new devices have an ultra-high write endurance capability to allow more than one million cycles for each memory location to meet the requirements for today’s high-write endurance applications.”
