STMicroelectronics added a new contactless smartcard microcontroller (MCU) with 2KB of EEPROM to its ST19 family of secure MCUs.

Promising to bring new benefits to operators, card issuers and card embedders alike, the ST19WR02 chip will allow application developers to build solutions to match the requirements of payment-card and transport operators. Finance applications will benefit from the IC's fast contactless interface for 'Wave, Pay, and Go' convenience, while maintaining the highest levels of security. Contactless payment cards based on the ST19WR02 will enable banks to penetrate the cash-based retail environment, such as local stores, gas stations, fast food restaurants, and cinemas, where speed and convenience are important, said ST.

The high-speed ISO 14443 contactless interface of the ST19WR02 will allow card embedders to rapidly test and personalize their products, while reducing transaction times for users and increasing customer satisfaction, added the company. According to the press release, the ease of use, by embedders' application development teams, of the on-chip security features and cryptographic hardwarecoupled with availability of advanced development tools and backward compatibility with previous productswill allow the rapid deployment of new applications.

The new chip is built using 0.18?m technology. In addition to its 2KB of EEPROM, it includes 64KB of ROM and 1KB of user RAM. A hardware DES cryptographic processor, with library support for symmetrical algorithms, is complemented by a broad collection of high level memory and anti-intrusion security features. It is supplied in micromodule or wafer form. The IC is approximately priced at $1.20, depending on quantity and final packaging.
