Product details
Overview
AT83C25OK100-RDTIM from Atmel is a certified smart card interface controller IC for PCMCIA-based readers, compliant with ISO 7816 and EMV 2000, supporting T=0/T=1 protocols, 1.8V/3V/5V smart cards, 60 mA card power supply, and auto-detection of card type and movement. It targets secure payment terminals and embedded banking systems.
For engineers reviewing the AT83C25OK100-RDTIM datasheet, AT83C25OK100-RDTIM pinout, AT83C25OK100-RDTIM application, or AT83C25OK100-RDTIM equivalent, key selection criteria include PCMCIA host interface compliance, dual-voltage smart card support, thermal/short-circuit protection, WHQL and EMV 2000 certification status, and VQFP64 package integration readiness.
Technical Context
The AT83C25OK100-RDTIM implements a dedicated smart card interface engine with hardware-level protocol handling for T=0 and T=1, integrated card power regulation (60 mA), and automatic card insertion/removal detection with auto-power-off. It embeds firmware for ISO 7816-3 physical layer signaling and supports TWI (S=8), SLE4432/42 (S=10), and SLE4418/28 (S=9) variants.
Its host interface is strictly PCMCIA-compliant with 16 Mbit/sec transmission speed and requires no external driver development for Windows 98/ME/NT4.0/2000/XP/CE 3.0, Linux, or macOS X - all drivers are delivered pre-certified and bundled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Smart Card Voltage Support | 1.8 V, 3 V, and 5 V - enables single-reader compatibility across legacy and modern contact smart cards. |
| Card Power Supply | 60 mA max - sufficient to drive high-current EMV-compliant cards without external boost circuitry. |
| Host Interface | PCMCIA Type II - direct plug-in capability into notebook or industrial PCMCIA slots without bridge logic. |
| Data Rate | 16 Mbit/sec - meets PCMCIA 2.1 timing requirements for burst-mode smart card data transfer. |
| Certifications | WHQL, EMV 2000, ISO 7816, HBCI, PCMCIA - eliminates need for end-system re-certification in financial and e-banking deployments. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded reader applications including kiosks and point-of-sale terminals. |
| Package | VQFP64 - 10 mm × 10 mm footprint with 0.5 mm pitch, optimized for compact PCMCIA module PCB layout. |
Pinout & Package
VQFP64 (Very Thin Quad Flat Package, 64-pin), 10 mm × 10 mm body, 0.5 mm lead pitch, exposed thermal pad (not electrically connected), moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Core & I/O supply | 3.3 V nominal - powers internal logic and PCMCIA interface buffers; decoupling required per PCMCIA spec. |
| VCCCARD | Smart card power output | Programmable 1.8/3/5 V output - regulated by on-chip DC-DC converter; delivers up to 60 mA with short-circuit foldback. |
| RST | Smart card reset control | Open-drain active-low output - drives card RST pin with slew-rate controlled edge for ISO 7816-3 timing compliance. |
| CLK | Smart card clock input | Driven by internal PLL - generates precise 1–5 MHz card clock from 3.3 V system clock; supports automatic frequency adaptation. |
| I/O | Smart card data bidirectional | Level-shifted, ESD-protected I/O - handles T=0/T=1 protocol data exchange with built-in voltage translation and noise filtering. |
| CD | Card detect input | Active-high digital input - detects mechanical card insertion/removal; triggers auto-power-off sequence within 100 ms. |
| PCMCIA Address/Data Bus | Host interface signals | Pins A0–A9, D0–D15 - directly connects to PCMCIA slot address/data lines; no glue logic needed for Type II mode. |
Key Features
| Feature | Design Value |
|---|---|
| Auto card type detection | Identifies SLE44x2, SLE44x8, and TWI cards at power-on - eliminates manual configuration and enables plug-and-play multi-card support. |
| Thermal & short-circuit protection | Shuts down VCCCARD within 2 µs on overtemperature (>125°C) or >70 mA sustained load - prevents damage during card fault conditions. |
| EMV 2000 pre-certification | Validated against Europay/Mastercard/Visa test suite - reduces end-product certification time from months to days for payment terminal OEMs. |
| PC/SC driver stack | Fully compliant with PC/SC v1.0+ - enables seamless integration with Windows Smart Card Resource Manager and third-party middleware (e.g., OpenSC). |
| 2-wire & 3-wire protocol support | Hardware-accelerated S=8 (TWI), S=10 (SLE4432), S=9 (SLE4418) modes - avoids firmware overhead and ensures deterministic timing for cryptographic operations. |
Applications
| Payment Terminal Integration | Banking Kiosk Reader |
|---|---|
Use Scenario: Embedded in countertop or self-service ATM/payment terminals requiring EMV L1/L2 certification. IC Role / Device Role / Timing Role: Primary smart card interface controller managing card power, reset, clock, and I/O under PCMCIA host arbitration. Use Value: Pre-certified EMV 2000 and WHQL compliance eliminates redundant validation; 60 mA VCCCARD supports dual-interface (contact + contactless bridge) power budgets. | Use Scenario: Integrated into public-access banking kiosks deployed in branch lobbies or retail environments. IC Role / Device Role / Timing Role: Secure card interface with auto-detection and thermal protection - critical for unattended operation with variable ambient temperature. Use Value: Auto card movement detection and power-off reduce standby current to <10 µA, extending kiosk uptime between maintenance cycles. |
| eID Document Reader | Healthcare Smart Card Station |
Use Scenario: Used in national eID card readers for citizen authentication in government service portals. IC Role / Device Role / Timing Role: ISO 7816-compliant interface handling PACE and BAC protocols for ICAO 9303 ePassports and national ID cards. Use Value: Supports 1.8 V cards (e.g., German eID) and 5 V legacy cards (e.g., French Carte Vitale) in same hardware - no redesign needed for multi-country deployment. | Use Scenario: Deployed in hospital registration stations for patient identity verification via health insurance smart cards. IC Role / Device Role / Timing Role: Reliable card interface with short-circuit protection - essential when non-technical staff insert cards repeatedly in high-traffic clinical settings. Use Value: On-chip thermal shutdown prevents field failures during extended use; HBCI certification ensures interoperability with German banking backend systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card interface controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INFINEON SLE66CLXX series | Integrated 8051 core, no PCMCIA interface; requires external bus interface logic and custom driver stack. | Targeted at standalone smart card readers with custom host MCU, not PCMCIA slot integration. | Select when designing non-PCMCIA form factor or needing higher security certification (Common Criteria EAL5+). |
| NXP SLB9635TT | TPM 1.2-compliant secure element with limited ISO 7816 interface; lacks EMV 2000 pre-certification and 60 mA card power. | Designed for platform authentication, not primary smart card reader functionality. | Select only if combining TPM and basic card I/O in resource-constrained designs - not a functional replacement for AT83C25OK100-RDTIM. |
Compared with SLE66CLXX and SLB9635TT, the AT83C25OK100-RDTIM uniquely delivers PCMCIA-native integration, full EMV 2000 pre-certification, and 60 mA programmable card power - making it the only drop-in solution for certified notebook-embedded or industrial PCMCIA smart card readers.
