Atmel launched a 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. They provide ultra-low power standby of 700 nA, 200 μA for write current, and 80 μA for read current at 25°C.
With confined spacing in smaller IoT, wearables, battery and cable identification applications, the AT21CS01/11 devices eliminate the need for external capacitors and rectifiers with their parasitic power scheme over a single data pin. Additionally, they have 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.
The AT21CS01/11 include a simple product identification with a plug-and-play 64-bit unique serial number in every device. The devices deliver an electrostatic discharge (ESD) rating compliant with IEC 61000-4-2 Level 4, so applications such as cables, consumables, etc. can tolerate exposure to the outside environment or direct human contact while still delivering flawless performance.
The chips adopt the I²C protocol, allowing for easy migration from existing EEPROM with less overhead and capability to connect up to eight devices on the same bus. The AT21CS01 devices offer a security register with a 64-bit factory programmed serial number and an extra 16 Bytes of user programmable and permanently lockable storage, delivering a guaranteed unique serial number for inventory tracking, asset tagging and can permanently protect the data if needed.
There are two variants of the device available to support different voltage requirements. The AT21CS01 is targeted for low-voltage applications operating at 1,7 V - 3,6 V. For applications that require higher voltage ranges such as Li-Ion/polymer batteries, the AT21CS11 will support a 2,7 V - 4,5 V operating range and is the ideal product to meet IEEE1725 specifications for electronic identification of battery packs.
