Product details
Overview
TDA8020HL/C2,118 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 or 5 V card supply (up to 60 mA per card), features an integrated multimode DC-to-DC converter (doubler/tripler/follower), and provides I²C-bus control with four addressable device options. It is used in banking terminals requiring simultaneous EMV2000-compliant card handling.
For engineers reviewing the TDA8020HL/C2,118 datasheet, TDA8020HL/C2,118 pinout, TDA8020HL/C2,118 application, or TDA8020HL/C2,118 equivalent, this page delivers verified technical context, exact pin functions, real-world activation/deactivation timing, ESD-protected card contact behavior, and validated alternative options for dual smart card interface design.
Technical Context
The TDA8020HL/C2,118 implements two independent ISO 7816-3 and EMV2000-compliant sequencers with hardware-controlled cold/warm reset, automatic ATR clock counting, and precise deactivation timing (tde = 50–100 µs). Its internal oscillator (2.0–3.2 MHz) clocks both sequencers and enables synchronous CLKIN/CLK output switching without pulse shortening.
It uses separate analog (VDDA/AGND) and digital (VDD/GND) supplies for the DC-to-DC converter, isolates interface signal references via VDDI (1.5–6.5 V), and provides open-drain I²C (SCL/SDA) and IRQ outputs compatible with host voltages exceeding VDD. The device enforces current limits on CLK (±70 mA), RST (±20 mA), I/O (±15 mA), and VCC (90 mA), triggering emergency deactivation upon violation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLB9670VQ2.0 | Trusted Platform Module (TPM) with integrated smart card controller; no dual-card support; requires external card interface circuitry | Designed for PC platform security-not for standalone card readers or EMV terminals | Choose only if system-level TPM functionality is required alongside card interface; not a functional replacement |
| ST8020 | Single-channel ISO 7816 interface; lacks dual-card capability, DC-to-DC converter, and I²C address selection pins (SAD0/SAD1) | Requires two ST8020 ICs plus external power management to match TDA8020HL/C2,118 functionality | Select when cost-per-channel is prioritized over integration; expect higher layout complexity and component count |

FAQ
What is the key difference between TDA8020HL/C1 and TDA8020HL/C2,118?
The TDA8020HL/C2,118 variant specifies an extended ambient temperature range of −40 °C to +85 °C (vs. −30 °C to +85 °C for C1), making it suitable for uncontrolled environments like outdoor banking kiosks. Its ATR timing window is also adjusted: for card activation, it uses 42100 CLK cycles before asserting MUTE (vs. 41950 for C1), providing tighter synchronization with EMV2000 v4.3 requirements. Both share identical pinout, registers, and electrical specs.
How does the TDA8020HL/C2,118 handle simultaneous dual-card operation under power constraints?
The TDA8020HL/C2,118 enforces a total current limit of 80 mA across both VCC outputs. When one card draws its maximum (60 mA at 5 V or 55 mA at 3 V), the other must operate below 20–25 mA. If VDD exceeds 3 V, both cards may draw full current simultaneously. The device monitors ICC1 + ICC2 in real time and triggers emergency deactivation if the sum exceeds 80 mA-ensuring safe, predictable power delivery without external supervision.
Can the TDA8020HL/C2,118 interface directly with a 1.8 V microcontroller?
Yes-the TDA8020HL/C2,118 supports independent VDDI (1.5–6.5 V) for interface signals. By connecting VDDI to 1.8 V, pins SCL, SDA, IRQ, SAD0, SAD1, CLKIN1/2, and I/O1uC/2uC operate at 1.8 V logic levels. SCL and SDA remain open-drain, so external pull-ups to 1.8 V are required. This eliminates level-shifting components while maintaining full I²C communication and interrupt functionality.
What protections does the TDA8020HL/C2,118 provide during card hot-swap events?
The TDA8020HL/C2,118 detects card insertion/removal via PRES1/PRES2 inputs and asserts IRQ with PRESL bit set. During hot removal, it executes an automatic emergency deactivation sequence: RST goes LOW, CLK stops, I/O goes LOW, and VCC ramps down with controlled slew rate (0.09–0.20 V/µs). Overcurrent on RST or VCC, overheating, or DC-to-DC failure also triggers immediate IRQ assertion and per-card deactivation-preventing latch-up or damage.
Is the TDA8020HL/C2,118 compliant with modern EMV specifications?
Yes-the TDA8020HL/C2,118 is explicitly specified to meet EMV2000 requirements, including ATR timing windows, cold/warm reset behavior, clock stability, and electrical characteristics per ISO/IEC 7816-3. Its sequencers implement the exact activation/deactivation timing defined in EMV2000 Book 1, and its 6 kV HBM ESD rating satisfies EMV Level 4 robustness requirements for card contact interfaces.
