2 Kb contactless memory IC

3 March 2010 DSP, Micros & Memory

Paving the way for more flexible e-ticketing, STMicroelectronics has introduced the SRi2K, a new 2 Kb IC enabling contactless tickets to manage access to multiple services.

The SRi2K leverages ST’s EEPROM technology to implement a large on-chip memory of 2 Kb density alongside RFID circuitry. This enlarged data capacity allows e-tickets to become more intelligent and flexible, to enable services such as transportation to become more efficient. It allows seamless access to transport modes such as bus, train, tram, taxi or cycle hire, for example, with one e-ticket. Due to its flexibility and enhanced features, it is also suitable for access control, event ticketing, vending machines and theme park applications.

Providing contactless access to its increased memory capacity, the SRi2K features integrated RFID circuitry operating at the standard 13,56 MHz carrier frequency and meeting all applicable international standards including ISO 14443-2/3 covering interfaces and data formatting. The IC also allows the implementation of security schemes, based on its unique 64-bit ID as well as lockable memory blocks.

An 8-bit anti-collision mechanism based on the chip ID allows large numbers of contactless tickets to co-exist without interfering. The chip’s fast memory access time and 106 Kbps data rate enable rapid communication between the ticket and reader, to speed up each transaction. For optimum reliability the SRi2K features dual 32-bit decrementing counters to prevent data loss, known as ticket tearing, in the event of power-failure while the ticket is being debited. The device is certified for one million erase/rewrite cycles and 40 year data retention.
