DS8007A-EAG+T

Specialized Overview

The DS8007A-EAG+T is an automotive-grade, multiprotocol dual smart card interface IC manufactured by Analog Devices Inc./Maxim Integrated. It supports ISO 7816, EMV, and GSM11-11 standards for two independent smart cards plus an auxiliary I/O. The device operates within a supply voltage range of 2.7V to 6V and features an integrated step-up converter generating 5.0V (max 65mA), 3.0V (max 50mA), and 1.8V (max 30mA) supplies. It includes an internal sequencer for automatic activation/deactivation, an 8-bit parallel bus with selectable multiplexed/nonmultiplexed modes, and an 8-character receive FIFO. The component is housed in a 48-pin LQFP package and functions across a temperature range of -40°C to +125°C.

Specialized Feature Summary

• Integrated voltage conversion supporting 1.8V, 3V, and 5V smart cards within a 2.7V to 6V system environment
• Dedicated internal sequencers automate T=0, T=1, and synchronous protocol handling including emergency deactivation
• Host connectivity via an 8-bit parallel bus configurable for direct connection to nonmultiplexed or multiplexed microcontroller buses

Specialized Applications

• Banking applications such as point-of-sale terminals and debit/credit payment terminals
• Automated teller machines (ATMs) and PIN pads
• Telecommunications access control systems
• Pay television interfaces

Specialized Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the 'E' designation ensures compliance with automotive grade requirements and extended temperature specifications. Ensure the ordering documentation explicitly references the lead-free/RoHS-compliant status associated with the '+' suffix to meet regulatory standards.

Specialized Selection Notes

Select the DS8007A-EAG+T for designs requiring simultaneous management of multiple smart card protocols in automotive environments. This component is suitable for hosts needing direct parallel bus integration without external protocol controllers. Consider the auxiliary I/O capabilities if additional serial interface functionality is required alongside standard dual-card operations.

Specialized Part Context

This component belongs to the DS8007A series of multiprotocol dual smart card interfaces. The '-EAG+' suffix specifies the automotive temperature grade (-40°C to +125°C), the 48-pin LQFP package, and lead-free/RoHS compliance. The base DS8007A provides the core functionality, while the suffix defines the environmental rating and physical form factor for industrial deployment.
