GENERAL DESCRIPTION
The Teridian Semiconductor Corporation 73S1217F is a
versatile and economical CMOS System-on-Chip device
intended for smart card reader applications. The circuit
features an ISO-7816 / EMV interface, an USB 2.0
interface (full-speed 12Mbps - slave) and a 5x6 PINpad
interface. Additional features include 8 user I/Os,
multiple interrupt options and an analog voltage input (for
DC voltage monitoring such as battery level detection).
Other built-in interfaces include an asynchronous serial
and an I2C interface.
The System-on-Chip is built around an 80515 high-
performance core. Its feature and instruction set is
compatible with the industry standard 8051, while
offering one clock-cycle per instruction processing
power (most instructions). With a CPU clock running up
to 24MHz, it results in up to 20MIPS available that
meets the requirements of various encryption needs
such as AES, DES / 3-DES and even RSA (for PIN
encryption for instance). The circuit requires a single 6
to 12 MHz crystal. An optional 32kHz crystal can be
connected to a sub-system oscillator with a real-time-
clock counter to enable stand-alone applications to
access an RTC value.
The respective 73S1217F embedded memories are;
64KB Flash program memory, 2KB user XRAM
memory, and 256B IRAM memory. On top of these
memories are added independent FIFOs dedicated to
the ISO7816 UART and to the USB interface.
The chip incorporates an inductor-based DC-DC
converter that generates all the necessary voltages to
the various 73S1217F function blocks (smart card
interface, digital core, etc.) from any of two distinct
power supply sources: The +5V USB bus (VBUS, 4.4V to
6.5V), or a main battery (VBAT, 4.0V to 6.5V). The chip
automatically powers-up the DC-DC converter with VBUS
if it is present, or uses VBAT as the supply input.
Alternatively, the pin VPC can support a wider power
supply input range (2.7V to 6.5V), when using a single
system supply source.
In addition, the circuit features an ON/OFF mode which
operates directly with an ON/OFF system switch: Any
activity on the ON/OFF button is debounced internally
and controls the power generation circuit accordingly,
under the supervision of the firmware (OFF request /
OFF acknowledgement at firmware level). The OFF
mode can be alternatively initiated from the controller
(firmware action instead of ON/OFF switch).
In OFF mode, the circuit typically draws less than 1μA,
which makes it ideal for applications where battery life
must be maximized.
Wake-up of the controller upon USB cable insertion is
supported.
Embedded Flash memory is in-system programmable
and lockable by means of on-silicon fuses. This makes
the Teridian 73S1217F suitable for both development and
production phases.
Teridian Semiconductor Corporation offers with its
73S1217F a very comprehensive set of software libraries,
including the smart card and USB protocol layers that are
pre-approved against USB, Microsoft WHQL and EMV,
as well as a CCID reference design. Refer to the
Teridian Semiconductor Corporation 73S12xxF Software
User’s Guide for a complete description of the Application
Programming Interface (API Libraries) and related
Software modules.
A complete array of development and programming
tools, libraries and demonstration boards enable
rapid development and certification of readers that
meet most demanding smart card standards.
APPLICATIONS
Hand-held PINpad smart card readers:
With USB or serial connectivity
Ideal for E-banking (MasterCard CAP, etc) and Digital
Identification (Secure Login, Gov’t ID...)
Transparent USB card readers and USB keys
General purpose smart card readers
ADVANTAGES
Reduced BOM
Larger built-in Flash / RAM than its competitors
Higher performance CPU core (up to 24MIPS)
On-chip DC-DC converter and CMOS switches for
battery and USB power
Sub-μA Power Down mode with ON/OFF switch
Powerful In-Circuit Emulation and Programming
A complete set of EMV4.1, USB and CCID libraries
Overall, the ideal compromise cost / features for high
volume, PINpad reader applications!
