Product details
Overview
DS8007A-EAG+T from Maxim Integrated is an automotive-grade multiprotocol dual smart card interface IC supporting ISO 7816, EMV™, and GSM11-11 standards. It provides full electrical interface and control for two independent smart cards plus auxiliary I/O for a third, integrates 1.8V/3V/5V voltage conversion, and features an internal UART with per-card variable baud-rate capability - deployed in banking POS terminals and secure access control systems.
For engineers reviewing the DS8007A-EAG+T datasheet, DS8007A-EAG+T pinout, DS8007A-EAG+T application, or DS8007A-EAG+T equivalent, key selection criteria include its dual-card activation sequencer, 8kV ESD protection on card interfaces, 2.7V–6V supply range, 48-pin LQFP automotive package, and support for nonmultiplexed/multiplexed 8-bit parallel host bus interfacing.
Technical Context
The DS8007A-EAG+T implements dedicated internal sequencers for automatic T=0/T=1/synchronous protocol activation/deactivation, including emergency deactivation during supply dropout. Its integrated DC-DC converter delivers regulated 5.0V±5% (65mA), 3.0V±8% (50mA), and 1.8V±10% (30mA) outputs to power diverse smart cards.
It supports both multiplexed and nonmultiplexed 8-bit parallel host interfaces via AD3–AD0 address selects and ALE detection logic, with separate 10MHz card clock generation (2× frequency doubling) and programmable clock stop modes (high/low/1.25MHz). The single UART is time-multiplexed across all card interfaces.

Applications
| Banking Point-of-Sale Terminal | EMV-Certified Payment Kiosk |
|---|---|
Use Scenario: Secure debit/credit card processing at retail checkout stations with dual-card reader capability for primary and backup cards. IC Role / Device Role / Timing Role: Dual smart card interface managing simultaneous T=1 protocol handshaking, voltage switching, and clock synchronization for two EMV-compliant cards. Use Value: Enables redundant card reading and hot-swappable card support while maintaining full EMVCo certification through integrated sequencers and voltage regulation. |
Use Scenario: Self-service payment kiosk in unattended locations requiring tamper-resistant, automotive-grade smart card handling. IC Role / Device Role / Timing Role: Automotive-qualified interface providing −40°C to +125°C operation, emergency deactivation on supply dropout, and 8kV ESD protection for public-access hardware. Use Value: Eliminates external reset supervisors and voltage translators - reduces BOM count and improves long-term field reliability in harsh environments. |
| Secure Physical Access Control Panel | Telecom SIM Card Reader Module |
Use Scenario: Multi-factor building entry system using dual smart cards (e.g., employee ID + cryptographic token) for layered authentication. IC Role / Device Role / Timing Role: Dual-interface controller coordinating independent activation sequences, separate clock domains, and isolated power delivery to prevent side-channel coupling. Use Value: Guarantees deterministic timing for ISO 7816-3 activation (tACT ≤ 130μs, tDE ≤ 150μs) - critical for real-time access decision latency. |
Use Scenario: Embedded SIM reader in pay-TV set-top boxes supporting legacy and next-gen UICC cards with mixed voltage requirements. IC Role / Device Role / Timing Role: Voltage-flexible interface delivering 1.8V/3V/5V to SIM slots while sharing UART resources across cards via time-division multiplexing. Use Value: Reduces PCB footprint versus discrete solutions - single 48-pin LQFP replaces dual-reader ICs plus level shifters and regulators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual smart card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3232ESE+ | RS-232 transceiver only - no smart card interface, voltage conversion, or protocol sequencers | Used for host-to-PC serial communication, not card reader subsystems | Select only if replacing legacy RS-232 level-shifting in non-smart-card designs |
| ST8024M | Single smart card interface, no auxiliary I/O, no integrated voltage converter - requires external 5V/3V supplies | Limited to one card slot; lacks automotive temperature rating and EMV-certified reference design | Consider for cost-sensitive single-card applications where extended temp range is not required |
Compared with MAX3232ESE+ and ST8024M, the DS8007A-EAG+T uniquely integrates dual-card protocol control, triple-voltage generation, and automotive qualification - making it the only drop-in solution for certified dual-slot EMV terminals requiring −40°C to +125°C operation and minimal external components.

This range is validated across all electrical specifications including card supply regulation, UART timing, and sequencer functionality - no derating is required within this span.
Does the DS8007A-EAG+T support both T=0 and T=1 smart card protocols?
Yes, the DS8007A-EAG+T supports both T=0 and T=1 protocols via dedicated internal sequencers that handle full activation, deactivation, and data exchange sequences per ISO 7816-3. It also supports synchronous card modes using C4/C8 lines - all without host MCU intervention beyond register configuration.
How does the DS8007A-EAG+T generate multiple card supply voltages?
The DS8007A-EAG+T uses an integrated step-up DC-DC converter with external capacitors on CPA1/CPA2/CPB1/CPB2/VUP pins to generate 5.0V±5% (65mA), 3.0V±8% (50mA), and 1.8V±10% (30mA) outputs. Voltage selection is software-controlled per card via PCR register bits, enabling mixed-voltage multi-card operation from a single 2.7V–6V input.
Can the DS8007A-EAG+T interface with an 80C51 microcontroller?
Yes, the DS8007A-EAG+T supports multiplexed 8-bit bus operation compatible with 80C51 derivatives. When ALE is enabled, D0–D7 carry address/data multiplexed signals, and MOVX instructions access registers - eliminating need for external address latches or glue logic in legacy 8051-based designs.
