Product Overview
The DS1961S-F5+ is an iButton 1Kb EEPROM with SHA-1 engine in F5 MicroCAN package. It combines 1024bits of EEPROM, 64bit secret, 8byte register/control page with up to five user read/write bytes, 512bit SHA-1 engine and fully featured 1-wire interface in a rugged iButton device. Data is transferred serially via 1-wire protocol which requires only single data lead and ground return. The DS1961S has an additional memory area called scratchpad that acts as a buffer when writing to main memory, register page or when installing a new secret. Data is first written to scratchpad from where it can be read back. After data has been verified, copy scratchpad command will transfer data to its final memory location provided that DS1961S receives matching 160bit message authentication code (MAC). Accessories permit DS1961S to be mounted on almost any surface including plastic key fobs and photo-ID badges.
- Reads and writes over wide voltage range of 2.8V to 5.25V from -40°C to +85°C

- World class security in stainless steel case for access control and eCash applications
- 128bits of 5V EEPROM memory partitioned into four pages of 256bits
- Overdrive mode boosts communication speed to 125Kbps
- On-chip 16bit CRC generator for safeguarding data transfers
- Communicates to host with single digital signal at 14.1Kb per second using 1-wire protocol
- Unique, factory lasered and tested 64bit registration number for absolute traceability
- Digital identification and information by momentary contact
- Easily affixed with self stick adhesive backing, latched by flange or locked with ring
