73S1210F  
Self-Contained Smart Card Reader  
with PINpad and Power Management  
Simplifying System Integration™  
DATA SHEET  
May 2009  
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).  
GENERAL DESCRIPTION  
The 73S1210F is a versatile and economical CMOS  
System-on-Chip device intended for smart card reader  
applications. The circuit is built around an 80515 high-  
performance core; it features primarily an ISO-7816 / EMV  
interface and a generic asynchronous serial interface.  
Delivered with turnkey Teridian embedded firmware, it  
forms a ready-to-use smart card reader solution that can be  
seamlessly incorporated into any microprocessor-based  
system where a serial line is available.  
In OFF mode, the circuit typically draws less than 1µA,  
which makes it ideal for applications where battery life  
must be maximized.  
The solution is scalable, thanks to a built-in I2C interface  
that allows to drive external electrical smart card interfaces  
such as Teridian 73S8010 ICs. This makes the solution  
immediately able to support multi-card slots or multi-SAM  
architectures.  
Embedded Flash memory is in-system programmable  
and lockable by means of on-silicon fuses. This makes  
the 73S1210F suitable for both development and  
production phases.  
In addition, the 73S1210 features a 5x6 PINpad interface, 8  
user I/Os, multiple interrupt options and an analog voltage  
input (for DC voltage monitoring such as battery level  
detection) that make it suitable for low-cost PINpad reader  
devices.  
Teridian Semiconductor Corporation offers with its  
73S1210F a very comprehensive set of software  
libraries for EMV. Refer to the 73S12xxF Software  
User’s Guide for a complete description of the  
Application Programming Interface (API Libraries) and  
related software modules.  
The 80515 CPU core 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 24MIPS  
available that meets the requirements of various encryption  
needs such as AES, DES / 3-DES and even RSA (for PIN  
encryption for instance).  
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  
The circuit requires a single 6MHz to 12MHz crystal.  
•
PINpad smart card readers:  
o
o
With serial connectivity  
Ideal for low-cost POS Terminals and Digital  
Identification (Secure Login, Gov’t ID, ...)  
The respective 73S1210F embedded memories are 32KB  
Flash program memory, 2KB user XRAM memory, and  
256B IRAM memory. Dedicated FIFOs for the ISO 7816  
UART are independent from the user XRAM and IRAM.

•
SIM Readers in Personal Wireless devices  
Payphones & Vending machines  
General purpose smart card readers  
Alternatively to the turnkey firmware offered by Teridian,  
customers can develop their own embedded firmware  
directly within their application or using Teridian 73S1210F  
Evaluation Board through a JTAG-like interface.  
ADVANTAGES  
•
•
Reduced BOM  
Versatile power supply options  
o
2.7V to 6.5V ranges  
The chip incorporates an inductor-based DC-DC converter  
that generates all the necessary voltages to the various  
73S1210F function blocks (smart card interface, digital  
core, etc.) from any of two distinct power supply sources:  
•
•
•
Higher performance CPU core (up to 24MIPS)  
Built-in EMV/ISO slot, expandable to multi-slots  
Flexible power supply options  
o
o
On-chip DC-DC converter  
CMOS switches between supply inputs  
the +5V bus (VBUS, 4.4 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 if VBUS is not present. Alternatively, the pin VPC  
can support a wider power supply input range (2.7V to  
6.5V), when using a single system supply source.

•
Sub-µA Power Down mode with ON/OFF switch  
Powerful In-Circuit Emulation and Programming  
A complete set of EMV4.1 / ISO7816 libraries  
Turnkey PC/SC firmware and host drivers
