MCU is smart choice for card readers
Single-chip microcontroller needs only a few passive external components to become a complete embedded smart-card reader solution.
A single-chip microcontroller for both PC-integrated and freestanding smart-card applications has come out of a partnership agreement between STMicoelectronics and smart-card reader specialist Gemalto The new ST7GEM is a secure MCU in ST's ST7 family, preprogrammed with smart-card interface software from Gemalto, and requiring the addition of only a few passive external components to become a complete embedded smart-card reader solution

Integrated smart-card readers are an increasingly popular security feature for laptop PCs, enabling user authentication, and protecting sensitive information in healthcare, banking, government and other areas.
The ST7GEM is already being used in production by a leading laptop manufacturer, and other industry leaders are currently evaluating and qualifying the device for their own PCs.
In addition, it is an ideal solution for stand-alone readers connected through a USB or serial interface, and for POS (point-of-sale) terminals, PIN pads, mobile phones, PDAs and set-top boxes.
"Our partnership with Gemalto has brought together the application and silicon expertise of the industry leaders to create an easy-to-use solution enabling any manufacturer to implement a smart-card reader", says Youssef Benmokhtar, Director of the 8bit Microcontroller Business Unit, STMicroelectronics.
"By sparing our customers the need to develop their own application software, we're providing access to the leading secure software while accelerating our customers' products' time to market".
"The synergies between STMicroelectronics, a leader in silicon technology, and Gemalto, a leader in digital security, will allow us to jointly promote this new original equipment manufacturer (OEM) offer", adds Alain Sigaud, Senior Vice-President for Smart Readers and Tokens at Gemalto.
"Its seamless and cost-effective integration into various devices embedding smart card capability will facilitate their expansion".
The ST7GEM peripherals include an ISO/IEC7816 serial host interface; USB 2.0-compliant interface; card power supply, with power-up/power-down control, ensuring compatibility with 5.0, 3.0 and 1.8V smart-card types; and a card management unit with card insertion and removal detection.
Drivers are embedded for a wide range of popular operating systems, and the whole package makes it straightforward to build an EMV-compliant smart-card interface.
In addition, the device includes 16Kbyte of Flash program memory and 768byte of RAM, as well as a timer, watchdog and low-voltage detector.
The ST7GEM is entering volume production now, and is available in 24-pin SO and QFN packages, priced at US $4.50 in quantities of 1000.
Sample quantities are also available.
It is supported by an evaluation kit developed by Gemalto, and by an application note with PCB recommendations, schematics and component bill of materials.
