Product details
Overview
TDA8002CT/C/C1,518 from NXP Semiconductors (formerly Philips) is an ISO 7816-compliant IC card interface IC designed to sit between smart cards and microcontrollers in secure transaction systems. It delivers regulated 3 V or 5 V card supply (±5%), supports up to 12 MHz card clock generation with synchronous frequency switching, integrates thermal/short-circuit protection, and provides automatic ISO 7816 activation/deactivation sequences - enabling use in banking terminals and GSM SIM readers.
For engineers reviewing the TDA8002CT/C/C1,518 datasheet, TDA8002CT/C/C1,518 pinout, TDA8002CT/C/C1,518 application, or TDA8002CT/C/C1,518 equivalent, key selection criteria include its dual-voltage card supply capability (3 V/5 V), integrated step-up converter for VCC generation, EMV/GSM11.11 compliance, low-power sleep mode (<150 µA), and SO28 package compatibility with legacy reader designs.
Technical Context
The TDA8002CT/C/C1,518 implements a fully autonomous analog interface with three protected half-duplex buffered I/O lines (I/O, AUX1, AUX2), internal oscillator (2.5 MHz typ.), and external crystal support (2–24 MHz). Its sequencer executes deterministic activation (180–220 µs) and deactivation (50–100 µs) sequences per ISO 7816-3, while the voltage supervisor triggers ALARM pulses (6–20 ms) during VDD transients.
It features dual-domain power architecture: VDDA/VDDD (3.0–6.5 V) powers logic and interfaces, while VCC output (3 V ±5% or 5 V ±5%) drives the card under controlled slew rate (0.10–0.20 V/µs) and current limiting (55 mA max, 200 mA short-circuit). Chip select (CS) enables parallel multi-interface configurations with high-impedance isolation of I/OUC/AUX1UC/AUX2UC when inactive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VDD) | 3.0–6.5 V - supports single-supply operation in both 3.3 V and 5 V host systems without level-shifting circuitry. |
| Card Supply (VCC) | 3 V ±5% or 5 V ±5% - programmable via CV/TV pin; regulated output capable of sourcing up to 55 mA for ISO-compliant card powering. |
| Card Clock Frequency | 0–12 MHz - internally generated; synchronous frequency changes enabled for dynamic protocol adaptation (e.g., T=0/T=1 switching). |
| Supply Current (Idle) | ≤5 mA at 10 MHz CLKOUT - enables low standby power in always-on card readers without compromising clock stability. |
| Supply Current (Sleep) | ≤150 µA - reduces system-level power consumption during card absence or idle polling intervals. |
| Deactivation Duration | 50–100 µs - ensures rapid, safe card disconnection meeting ISO 7816-3 timing requirements for contact separation. |
| ESD Protection (Card Side) | >6 kV HBM - protects against electrostatic discharge during card insertion/removal in uncontrolled environments. |
Pinout & Package
Package: SO28 - plastic small outline package, 28 leads, body width 7.5 mm (SOT136-1). Compatible with standard surface-mount assembly and legacy PCB footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL2 | Crystal oscillator input/output | Supports 2–24 MHz quartz crystals; enables precise clock generation for ISO-compliant card timing without external PLL. |
| I/O, AUX1, AUX2 | Card-side bidirectional data lines | Three protected half-duplex transceivers with anti-latch logic; tolerate VCC ≠ VDD and support 200 kHz max data rate. |
| VCC | Card supply output | Regulated 3 V or 5 V output with short-circuit protection and controlled rise/fall times (0.10–0.20 V/µs) per ISO 7816-3. |
| RST, CLK | Card reset and clock outputs | Drive C2I and C3I contacts directly; RST delay ≤100 ns, CLK duty cycle 45–55%, rise/fall ≤8 ns (CL = 30 pF). |
| CV/TV | Card voltage selection input | Active-HIGH selects 5 V; LOW selects 3 V - sets VCC regulation target before activation sequence begins. |
| CS | Chip select input | Enables parallel use of multiple TDA8002CT/C/C1,518 devices; disables I/OUC/AUX1UC/AUX2UC when LOW (100 kΩ pull-up). |
| MODE | Sleep mode control | LOW enters low-power mode (≤150 µA); requires ≥6 ms wake-up delay and 16 kHz CLKOUT stabilization before resuming active mode. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic ISO 7816 activation/deactivation | Hardware-sequenced 180–220 µs activation and 50–100 µs deactivation - eliminates firmware timing-critical code for contact management. |
| Step-up converter for VCC generation | Generates regulated 3 V or 5 V from 3.0–6.5 V VDD - removes need for external DC-DC converter in compact reader designs. |
| Enhanced ESD protection (>6 kV) | Integrated protection on all card-contact pins (I/O, RST, CLK, VCC, AUX1, AUX2, PRES) - meets IEC 61000-4-2 Level 4 for rugged field deployment. |
| EMV/GSM11.11/ISO 7816 compliance | Fully compliant with Europay/MasterCard/Visa, GSM phase 2+, and ISO/IEC 7816-3 standards - certified for payment and telecom applications. |
| Thermal and short-circuit protection | Shut-down at 135 °C junction temperature; limits VCC output current to 90 mA during overload - prevents damage during card faults or misinsertion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IC card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLB9670 | TPM-integrated secure microcontroller with built-in ISO 7816 interface; requires external VCC regulator and lacks step-up converter. | Targets secure boot and cryptographic offload; not drop-in for pure analog interface replacement. | Select when end-system requires hardware-rooted trust; avoid when only analog card interfacing is needed. |
| MAX3232E | RS-232 transceiver only; no VCC regulation, clock generation, or ISO 7816 sequencing logic. | Limited to serial communication bridging; cannot replace TDA8002CT/C/C1,518's full card interface functionality. | Use only for UART-level signal translation - not a functional alternative for smart card readers. |
Compared with SLB9670 and MAX3232E, the TDA8002CT/C/C1,518 uniquely integrates VCC step-up, ISO-compliant sequencer, and triple buffered I/O in a single SO28 package - making it irreplaceable for cost-sensitive, space-constrained readers requiring full analog card control without firmware overhead.

FAQ
What is the primary function of the TDA8002CT/C/C1,518 in a smart card system?
The TDA8002CT/C/C1,518 serves as a complete analog interface between a microcontroller and ISO 7816-compliant smart cards. It generates and regulates the card's VCC supply (3 V or 5 V), delivers precise clock signals up to 12 MHz, controls RST and I/O lines, and executes automatic activation/deactivation sequences - eliminating the need for discrete regulators, oscillators, and protection circuitry in the TDA8002CT/C/C1,518-based design.
Does the TDA8002CT/C/C1,518 support both 3 V and 5 V smart cards?
Yes, the TDA8002CT/C/C1,518 supports dual-voltage operation via the CV/TV pin: HIGH selects 5 V ±5% VCC output, LOW selects 3 V ±5%. This allows a single TDA8002CT/C/C1,518 design to interface with legacy 5 V cards and modern 3 V cards without hardware modification - provided the voltage selection is set before activation begins.
What package type is used for the TDA8002CT/C/C1,518?
The TDA8002CT/C/C1,518 uses the SO28 package (SOT136-1): a plastic small outline package with 28 leads and 7.5 mm body width. This surface-mount package is compatible with standard reflow processes and widely supported in legacy smart card reader PCB layouts.
How does the TDA8002CT/C/C1,518 handle card insertion and removal events?
The TDA8002CT/C/C1,518 monitors card presence via the PRES pin (active LOW) and initiates automatic ISO 7816-compliant activation upon CMDVCC assertion. During removal or fault conditions (e.g., short-circuit), it executes a deterministic deactivation sequence (50–100 µs) that safely ramps down VCC, disables CLK/RST, and isolates I/O lines - preventing electrical stress on the card or interface.
Is the TDA8002CT/C/C1,518 compliant with EMV and GSM standards?
Yes, the TDA8002CT/C/C1,518 is explicitly designed for EMV (Europay, MasterCard, Visa), GSM11.11, and ISO/IEC 7816-3 compliance. Its integrated sequencer, regulated VCC, ESD-hardened card pins (>6 kV), and precise timing parameters (e.g., tde ≤100 µs) meet the mandatory requirements for certified payment and telecom terminals using the TDA8002CT/C/C1,518.
