Product details
Overview
TDA8007BHL/C2,118 from NXP Semiconductors (formerly Philips) is a dual smart card interface IC supporting ISO 7816 T=0/T=1 protocols and EMV 3.1.1 compliance. It delivers independent 5 V/3 V/1.8 V dual-card power supplies (65 mA/50 mA/30 mA max), integrated ISO UART with FIFO, and hardware-controlled activation/deactivation sequences. It serves as the core interface controller in multi-protocol banking and access control readers.
For engineers reviewing the TDA8007BHL/C2,118 datasheet, TDA8007BHL/C2,118 pinout, TDA8007BHL/C2,118 application, or TDA8007BHL/C2,118 equivalent, key selection criteria include dual-card protocol handling, programmable ETU timing for ATR/WWT, step-up converter operation from 2.7–6 V, and LQFP48 package compatibility with 80C51-style parallel bus interfacing.
Technical Context
The TDA8007BHL/C2,118 implements a dedicated ISO 7816 UART with parallel-access registers, supporting both multiplexed (ALE-driven) and non-multiplexed (AD0–AD3 address decoding) 8-bit bus configurations. Its register architecture includes per-card PCR, UCR1/UCR2, GTR, PDR, and CSR for independent T=0/T=1 parameter management.
Hardware-level security features include ESD protection ≥6 kV on card I/O pins, short-circuit current limiting on VCC1/VCC2/RST1/RST2/I/O1/I/O2, and supply supervisor-triggered reset. The integrated step-up converter supports doubler/tripler/follower modes, enabling single-supply operation across 2.7–6 V while generating stable card voltages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLB9670 | Trusted Platform Module (TPM) with integrated smart card controller - lacks dual-card support and external ISO UART interface. | Designed for PC platform root-of-trust, not standalone card readers. | Select only when cryptographic key storage and attestation are primary requirements over multi-card flexibility. |
| TDA8020 | Single-card interface IC with identical register map and pinout - no dual-card logic, no shared UART, no CSR register. | Targeted at cost-sensitive single-slot readers where dual functionality is unnecessary. | Choose for simplified design and lower unit cost when only one card slot is required and TDA8007BHL/C2,118's dual-channel capability is unused. |
Compared with SLB9670 and TDA8020, the TDA8007BHL/C2,118 uniquely provides hardware-managed dual-card protocol arbitration, shared ISO UART with per-card register banks, and integrated step-up conversion - making it the only option for compact, single-supply, dual-protocol EMV readers requiring no external power management.

FAQ
What protocols does the TDA8007BHL/C2,118 support?
The TDA8007BHL/C2,118 supports ISO/IEC 7816-3 asynchronous T=0 and T=1 protocols and is certified for EMV 3.1.1 compliance. It does not support EMV 2000 or synchronous card protocols beyond basic ISO 7816 Annex A extensions. Protocol selection is managed per-card via UCR1/UCR2 registers, and the hardware UART handles character framing, parity, and guard time generation without host intervention.
How does the TDA8007BHL/C2,118 handle dual-card power sequencing?
The TDA8007BHL/C2,118 implements independent power control for each card via dedicated PCR registers, enabling staggered activation (225 µs max), controlled voltage ramp (0.05–0.22 V/µs), and hardware-enforced deactivation (150 µs max). Each VCC1/VCC2 output supports 5 V/3 V/1.8 V selection with overload detection at 100 mA - ensuring EMV-compliant power delivery without external supervisors or sequencers.
Can the TDA8007BHL/C2,118 operate from a 3.3 V supply?
Yes, the TDA8007BHL/C2,118 operates from a 2.7 V to 6 V VDD supply. At VDD = 3.3 V, it delivers full functionality including step-up conversion to generate 5 V card supplies (65 mA), 3 V supplies (50 mA), or 1.8 V supplies (30 mA). The internal step-up converter uses external 220 nF capacitors on VUP/SAP/SBP/SAM/SBM pins and requires no additional inductors or controllers.
What is the purpose of the DELAY pin on the TDA8007BHL/C2,118?
The DELAY pin on the TDA8007BHL/C2,118 connects to an external capacitor that sets the duration of the internal power-on reset pulse (RSTOUT) and stabilizes the step-up converter startup sequence. A typical 100 pF capacitor yields ~10 µs delay; values from 10 pF to 1 nF are supported. This pin ensures reliable initialization timing across temperature and voltage variations without requiring external RC networks.
Does the TDA8007BHL/C2,118 support hot-plug detection for smart cards?
Yes, the TDA8007BHL/C2,118 provides dedicated PRES1 and PRES2 inputs with Schmitt-trigger thresholds for reliable card insertion/removal detection. These pins feed directly into the Hardware Status Register (HSR), where PRL1/PRL2 bits latch level changes and assert the INT pin. No external pull-ups or debouncing circuitry is required - the internal hysteresis and noise filtering meet EN 61000-4-2 immunity requirements.
