DS8023 Description
The DS8023 smart card interface IC is a low-cost, lowpower, analog front-end for a smart card reader designed for all ISO 7816, EMV , and GSM11-11 applications. The DS8023 supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption. The DS8023 is available in 28-pin TSSOP and SO packages, and can often be used as a replacement for the TDA8024 with little or no application...
