Product details
Overview
TDA8020HL/C1,118 from NXP Semiconductors (formerly Philips) is a dual ISO/EMV-compliant smart card interface IC designed for secure transaction systems. It integrates two independent 6-contact card interfaces, supports 3 V and 5 V card supply with up to 60 mA per card, features an integrated multimode DC-to-DC converter (doubler/tripler/follower), and communicates via I²C-bus with four configurable device addresses. It is used in banking terminals requiring EMV2000-certified card activation, reset sequencing, and fault-safe deactivation.
For engineers reviewing the TDA8020HL/C1,118 datasheet, TDA8020HL/C1,118 pinout, TDA8020HL/C1,118 application, or TDA8020HL/C1,118 equivalent, this page delivers verified technical context, exact pin functions, real-world smart card interface design constraints, ESD-hardened contact protection, and validated alternative options for dual-card terminal designs.
Technical Context
The TDA8020HL/C1,118 implements two independent ISO 7816-3/EMV2000-compliant sequencers with automatic cold/warm reset, clock count supervision, and presence detection. Its internal oscillator (2.5 MHz typ.) drives precise activation/deactivation timing-tde = 50–100 µs-with controlled VCC slew rates (0.09–0.14 V/µs) and built-in voltage supervisor (Vth1 = 2.1–2.4 V, hysteresis 50–100 mV).
It uses a capacitor-based DC-to-DC converter with mode selection based on VDD and target VCC: doubler (≈5.5 V) below 3.4 V input for 5 V cards, tripler (≈5.5 V) for 3 V cards at low VDD, or follower (VDD passed to VUP) above 3.5 V. Separate VDDI (1.5–6.5 V) powers I²C, IRQ, and host-side I/O pins, enabling mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 2.7 V to 6.5 V - supports single-supply operation across battery, USB, and industrial rails |
| VCC Output | 5 V ±2.5% or 3 V ±5% - meets ISO 7816-3 voltage tolerance for both card types |
| Card Current | 60 mA max per 5 V card, 55 mA per 3 V card - with 80 mA total ICC1+ICC2 limit enforcing power budgeting |
| I²C Interface | 400 kHz fast-mode slave - enables real-time status polling and control without MCU overhead |
| ESD Protection | ±6 kV HBM on card contacts - satisfies IEC 61000-4-2 Level 4 for field-deployed terminals |
| Thermal Range | −30 °C to +85 °C - qualified for commercial-grade set-top boxes and banking peripherals |
| Deactivation Time | 50–100 µs - ensures rapid, safe card disconnection during emergency events |
Pinout & Package
LQFP32 package (SOT358-1), 7 × 7 × 1.4 mm body, 32-pin quad flat with exposed thermal pad (not electrically connected). Pin 1 marked by dot; pin numbering follows standard counter-clockwise LQFP convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PRES1, PRES2 | Card presence sense inputs | Active-HIGH detection of physical card insertion; triggers sequencer readiness |
| VCC1, VCC2 | Smart card power outputs | Regulated 3 V or 5 V supplies with current limiting (90 mA max) and ripple <350 mV p-p |
| CLK1, CLK2 | Card clock outputs | Driven by internal oscillator or external CLKIN; current-limited to ±70 mA for short-circuit resilience |
| RST1, RST2 | Card reset outputs | Open-drain compatible; LOW during activation, HIGH after timeout or ATR failure; ±20 mA current limit |
| I/O1, I/O2 | Card data I/O | Internal 14 kΩ/15 kΩ pull-ups to respective VCC; ±15 mA current limit; ISO 7816-3 compliant signaling |
| SCL, SDA, IRQ | I²C bus and interrupt | Open-drain, level-shifted to VDDI - allows interfacing with 1.8 V/3.3 V MCUs without external translators |
| VDD, VDDA, VDDI, AGND, GND | Power domains | Separate analog (VDDA/AGND) and digital (VDD/GND) supplies; VDDI isolates interface logic from noisy DC-DC switching |
| SAP, SAM, SBP, SBM, VUP, CDEL | DC-to-DC converter nodes | Require 220 nF ceramic caps (ESR <100 mΩ); CDEL sets supervisor delay (1 ms per 2 nF) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent ISO/EMV sequencers | Hardware-enforced activation/deactivation per ISO 7816-3, eliminating MCU firmware timing risks |
| Auto-configuring DC-to-DC converter | Selects doubler/tripler/follower mode dynamically based on VDD and card voltage - no external configuration needed |
| Integrated voltage supervisor | Monitors VDD, asserts IRQ and sets SUPL bit on drop-out - triggers emergency deactivation before card corruption |
| Per-pin current limiting | Hardware limits on CLK, RST, I/O, and VCC prevent latch-up and enable fail-safe operation during faults |
| Four-device I²C address space | SAD0/SAD1 pins support up to four TDA8020HL devices on one bus - scalable for multi-slot readers |

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 |
|---|---|---|---|
| SLB9670 | Trusted Platform Module (TPM) with integrated smart card controller - not a pure interface IC; lacks dual independent VCC control and sequencer autonomy | Designed for PC platform security, not embedded terminal use; requires full TPM stack, not ISO 7816 direct access | Choose only if system requires TPM 2.0 compliance alongside card interface - adds software complexity and cost |
| ST8020 | Pin-compatible dual interface but lacks integrated DC-to-DC converter - requires external charge pump and separate 3 V/5 V regulators | Higher BOM count and layout area; no automatic VDD-to-VCC mode selection - increases firmware configuration burden | Select when existing design already includes discrete power circuitry and board space permits added components |
Compared with SLB9670 and ST8020, the TDA8020HL/C1,118 uniquely combines autonomous dual-card sequencers, integrated multimode DC-to-DC conversion, and hardware-level fault response - reducing component count, firmware effort, and validation scope for ISO/EMV terminal designs.

FAQ
What is the maximum total current the TDA8020HL/C1,118 can deliver to both smart cards simultaneously?
The TDA8020HL/C1,118 supports a maximum combined card supply current (ICC1 + ICC2) of 80 mA. This means if one card draws its full rated 60 mA (at 5 V), the other must operate below 20 mA. At VDD > 3 V, both cards may draw up to 60 mA each for 5 V operation or 55 mA each for 3 V operation - but only when total current remains within the 80 mA limit. The TDA8020HL/C1,118 enforces this via internal current limiting and automatic deactivation on overload.
Does the TDA8020HL/C1,118 support both 3 V and 5 V smart cards concurrently?
Yes, the TDA8020HL/C1,118 supports independent 3 V and 5 V operation per card slot: VCC1 and VCC2 can be set to different voltages via I²C control bits (bit 2 of CONTROL byte). Each output delivers regulated 3 V ±5% (2.85–3.15 V) or 5 V ±2.5% (4.75–5.25 V), with ripple under 350 mV p-p. The integrated DC-to-DC converter automatically selects doubler/tripler/follower mode to generate required VCC from a single 2.7–6.5 V VDD rail - no external regulators needed for the TDA8020HL/C1,118.
How does the TDA8020HL/C1,118 handle card insertion and removal events?
The TDA8020HL/C1,118 detects card presence via dedicated PRES1 and PRES2 inputs (active HIGH). Insertion triggers IRQ assertion and sets PRESL bit in the STATUS register; removal during active session initiates automatic emergency deactivation - pulling RST LOW, stopping CLK, and ramping VCC down with controlled slew rate (0.09–0.14 V/µs). The TDA8020HL/C1,118 also monitors for card take-off during transactions and asserts PROT bit on IRQ if detected - ensuring data integrity and preventing partial writes.
What I²C address options are available for the TDA8020HL/C1,118?
The TDA8020HL/C1,118 provides four unique I²C slave addresses using SAD0 and SAD1 pins: LOW/LOW = 0x40 (card 1) / 0x48 (card 2); LOW/HIGH = 0x42 / 0x4A; HIGH/LOW = 0x44 / 0x4C; HIGH/HIGH = 0x46 / 0x4E. Each device responds to two addresses - one per card interface - enabling independent control of both slots over a shared bus. The TDA8020HL/C1,118 operates in standard (100 kHz) and fast (400 kHz) I²C modes, with open-drain SCL/SDA pins tolerant of pull-up voltages up to VDDI.
Is the TDA8020HL/C1,118 RoHS-compliant and lead-free?
Yes, the TDA8020HL/C1,118 is RoHS-compliant and lead-free, manufactured in accordance with EU Directive 2011/65/EU. The LQFP32 package (SOT358-1) uses lead-free solderable terminations and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 3. Full compliance documentation, including substance declarations and test reports, is available through NXP's official product support portal for the TDA8020HL/C1,118.
