Available now from Alpha Micro Components, the Teridian 73S1217F is a single-chip PINPad smart card reader with power management features and dedicated USB and serial interfaces. The 73S1217F offers a low cost yet feature-heavy combination which makes it ideal for high volume PINPad reader applications.
The Teridian 73S1217F is a single-chip smart card terminal solution, optimised to build low-cost, handheld PINPad card readers.
It is particularly suited to combination devices that can be used either in unconnected stand-alone mode or attached to a computer by USB.
This means that personal PINPads, for use in applications such as e-banking or digital identification, can now take advantage of the USB connectivity with almost no impact on the cost, when compared with traditional unconnected solutions.
Other potential applications include transparent smart card and SIM readers, and general purpose smart card readers.
Key advantages of the new Teridian 73S1217F microchip involve reduced bill of materials, larger built-in Flash/RAM than its competitors and a higher performance CPU core of up to 24MIPS.

Flash and masked ROM options are available together with powerful in-circuit emulation and programming with a complete set of ISO7816, EMV4.1, PC/SC, USB and CCID libraries.
The new Teridian 73S1217F is built around the Teridian 80515 core, offering the features of the Teridian 73S1215F with the addition of a DC/DC convertor and several built-in power management features.
When in USB mode, it operates from a single power supply, either the USB bus power or from a set of batteries, and as stand-alone the device uses a 2.7-6.5V power supply.
The Teridian 73S1217F can drive a main system on/off switch, which internally controls the power generation circuit.
In off mode, the circuit typically draws less than 1uA, which makes it ideal for applications where battery life must be maximised.
Teridian provides a free-of-charge CCID reference design including embedded firmware compatible with Windows standard CCID driver, and Teridian's proprietary CD driver, which supports additional features such as PINPad, display, multicard slots that are not supported by the Windows CCID driver.
This CCID reference design is fully compliant with EMV 4.1 and WHQL(1).
Teridian also offers a specially designed development kit for assessing and testing the 73S1217F, as well as a Flash programmer, which can be used for test on the production line or in the field to program 73S1217F devices through JTAG-like interface, directly on the PCB.
Christos Papakyriacou, Managing Director of Alpha Micro commented: 'With the increasing rise of Internet fraud and 'cardholder not present' type transactions, this new device will be a big help in assisting our customers to develop low cost solutions to combat this serious crime'.
'Teridian Semiconductor's extensive knowledge in the arena simplifies the whole process of adopting such technologies and will greatly assist the fight against credit card fraud'.
