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

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

Self-Contained PINpad, Smart Card Reader

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.
