Smart Card Interface

General Description

The DS8313 smart card and SIM interface IC is a low-

cost, analog front-end for a smart card reader designed

for smart card applications that do not require the use

of the auxiliary card I/O contacts C4 and C8 (AUX1 and

AUX2). The DS8313 supports 5V, 3V, and 1.8V smart

cards. The absence of a charge pump reduces active

power consumption, and the DS8313 also supports an

ultra-low-power 10nA stop mode.

The DS8313 is designed to interface between a system

microcontroller and the smart card interface, providing

all power supply, protection, and level shifting required

for IC card applications.

The DS8314 is similar to the DS8313, but only uses one

analog (smart card) power supply. Therefore, the

device has reduced ability to provide power to smart

cards, but it is still sufficient for many applications,

allowing the DS8314 to drop into many TDA8024 sock-

ets without hardware changes.

The DS8313L and DS8314L use a negative polarity-pres-

ence detect instead of the default positive-polarity detect.

Both devices are available in a 28-pin SO package.
