GENERAL DESCRIPTION
The Teridian Semiconductor Corporation 73S1209F is a
versatile and economical CMOS System-on-Chip device
intended for smart card reader applications. More
generally, it is suitable anywhere a UART to ISO-7816 /
EMV bridge function is needed. 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 73S8010R/C ICs. This makes the solution
immediately able to support multi-card slots or multi-SAM
architectures.
In addition, the 73S1209F features a 5x6 PINpad interface,
9 user I/Os, 2 LED outputs (programmable current),
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 73S1209F embedded memories are 32KB
Flash program memory, 2KB user XRAM memory, and
256B IRAM memory. Dedicated FIFOs for the ISO7816
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 73S1209F
Evaluation Board through a JTAG-like interface.
Overall, the Teridian 73S1209F IC requires 2 distinct power
supply voltages to operate normally with full support of all
smart card voltages, 1.8V, 3V and 5V. The digital power
supply V
DD
requires a 2.7V to 3.6V voltage, and the analog
power supply V
PC
requires typically a 4.75V to 6.0V.
While the V
DD
is used to power up the CPU core and the
digital functions of the IC, the V
PC
voltage is used to supply
the proper V
CC
voltage to the smart card interface: The chip
incorporates an low drop-out linear voltage regulator that
generates the smart card power-supply V
CC
from the power
supply source V
PC
.
Embedded Flash memory is in-system programmable
and lockable by means of on-silicon fuses. This makes
the 73S1209F suitable for both development and
production phases.
Teridian Semiconductor Corporation offers with its
73S1209F 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.
