GENERAL DESCRIPTION
The 73S1215F 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 device) and a 5x6 PINpad
interface. Maximum design flexibility is supported
with additional features such as 9 user I/Os,
multiple interrupt options, up to 4 programmable
current outputs (to drive external LEDs), and 1
analog voltage input (suitable for DC voltage
monitoring such as battery level detection). Other
built-in hardware interfaces include an
2
asynchronous serial UART and an I C 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 20 MIPS 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 crystal, which frequency can be
between 6MHz and 12MHz. In addition, a 32768
Hz sub-system oscillator (optional) with an
independent real-time-clock counter enables stand-
alone applications to access an RTC value. The
respective 73S1215F embedded memories are;
64KB Flash program memory, 2KB user XRAM
memory, and 256B IRAM memory. In addition to
these memories are independent FIFOs dedicated
to the ISO7816 UART and to the USB interface.
Overall, the 73S1215F offers a cost effective
solution to implement hand-held PINpad smart card
readers - USB connected, serial connected,
standalone or combo – as well as turnkey smart
®
card reader modules, USB or ExpressCard type.
Embedded Flash memory is in-system
programmable and lockable by means of on-silicon
fuses. This makes the Teridian 73S1215F suitable
for both development and production phases.
Teridian Semiconductor Corporation offers with
its 73S1215F 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
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 smart card readers that meet
most demanding smart card standards.
