DS8313 Description
The DS8313 smart card and SIM interface IC is a lowcost, 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.
