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.
The solution is scalable, thanks to a built-in I
2
C 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.
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.
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).
The circuit requires a single 6MHz to 12MHz crystal.
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.
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.
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:
the +5V bus (V
BUS
, 4.4 to 6.5V), or a main battery (V
BAT
,
4.0V to 6.5V). The chip automatically powers-up the DC-
DC converter with V
BUS
if it is present, or uses V
BAT
as the
supply input if V
BUS
is not present. Alternatively, the pin V
PC
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.
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.
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.
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.
