DESCRIPTION
The 73S8014BN is a single smart card (ICC) interface circuit
that is firmware compatible (in most cases) with 8024-type
devices. It is derived from the 73S8024RN industry-standard
electrical interface, but adds support for 1.8V smart card
applications. The 73S8014BN has been optimized to match
set-top
box/A/V
conditional
access
applications.
The
optimization adds functionality while creating a device with a
smaller pin count.
The 73S8014BN interfaces with the host processor through the
same bus (digital I/Os) as the 73S8024RN and most other
8024 type devices. As a result, the 73S8014BN is a very
attractive cost-reduction path from traditional 8024 ICs.
The 73S8014BN has been designed to provide full electrical
compliance
with
ISO
7816-3,
EMV
4.2,
and
NDS
specifications.
Interfacing with the system controller is done through a control
bus, composed of digital inputs to control the 73S8014BN, and
one interrupt output to inform the system controller of the card
presence, device readiness and faults.
The card clock can be generated by an on-chip oscillator using
an external crystal or by connection to an externally supplied
clock signal. In addition, the clock divider provides divisor
values of divide by 1, 2, 4, and 8 that are controlled through a
single pin.
The
73S8014BN
incorporates
an
ISO
7816-3
activation/deactivation
sequencer
that
controls
the
card
signals. Level-shifters drive the card signals with the selected
card voltage (1.8V, 3V, or 5V), coming from an internal low
dropout (LDO) voltage regulator. This LDO regulator is
powered by a dedicated power-supply input, VPC. Digital
circuitry is powered separately by a digital power supply, VDD.
With its embedded LDO regulator, the 73S8014BN is a cost-
effective solution for any application where a 5V (typically -5%
+10%) power supply is available.
Emergency card deactivation is initiated upon card extraction
or upon any fault detected by the protection circuitry. The fault
can be a card overcurrent, VCC undervoltage, or power-supply
fault (VDD). The card overcurrent circuitry is a true current-
detection function, as opposed to VCC voltage drop detection,
as usually implemented in non-Teridian 8024 interface ICs.
The 73S8014BN contains a power-down mode with typical
power consumption of 1
A on each of the V
DD
and VPC
supplies. The power-down mode is controlled through existing
control pins without the need for a dedicated control pin.
