DATA SHEET
NOVEMBER 2005
DESCRIPTION
The
TERIDIAN
Semiconductor
Corporation
73S1121F is a CMOS single chip dual ISO-7816
smart-card terminal micro-controller that implements
all the functions required to build a low-cost dual
smart-card terminal with a USB interface, suitable for
various applications including EMVCo compliant
payment terminals. Its enhanced set of features
supports several configurations allowing low
component count and a fast design cycle. Based on
an 80C52 core, it incorporates communication and
man-machine interfaces. The TERIDIAN 73S1121F
device is applicable to either portable or host-
connected applications. Embedded Flash memory
makes the TERIDIAN 73S1121F a complete system-
on-chip suitable for both development and
production phases.
This data-sheet presents the package and pin
description, as well as the electrical features that are
unique to the TERIDIAN 73S1121F. It also presents
a brief description of the architecture and of its
embedded functions.
Refer to the 73S11xxF Hardware User’s Guide for
more detailed information about the microcontroller
architecture, description of the registers, description
of the different blocks that are common to the
TERIDIAN 73S11xxF smart card terminal controller
family.
Also refer to the TERIDIAN 73S11xxF Software
User’s Guide for a complete description of the
Application Programming Interface (API).
