DS8024
Smart Card Interface
Industry-Standard Smart Card Interface Provides Robust Communication
|
Status
Active: In Production.
Description
The DS8024 smart card interface IC is a low-cost, analog front-end for a smart card reader, designed for all ISO 7816, EMV*, and GSM11-11 applications. The DS8024 is a pin-for-pin drop-in replacement for the NXP TDA8024 and is offered in 28-pin TSSOP and SO packages.
Applications requiring support for 1.8V smart cards or requiring low power should consider the DS8113, which achieves lower active- and stop-mode power with minimal changes to application hardware and software.
