Product details
Overview
TDA8007BHL/C3,118 from NXP Semiconductors is a dual smart card interface IC supporting ISO 7816, EMV4.2, and GSM 11-11 protocols. It provides parallel bus control (8-bit non-multiplexed or multiplexed), integrated ISO UART with FIFO, dual VCC generation (5 V/3 V/1.8 V), and hardware-level ESD protection (6 kV min). It enables secure, low-power dual-card readers for banking terminals and access control systems.
For engineers reviewing the TDA8007BHL/C3,118 datasheet, TDA8007BHL/C3,118 pinout, TDA8007BHL/C3,118 application, or TDA8007BHL/C3,118 equivalent, key selection considerations include multiplexed/non-multiplexed bus compatibility, dual-card clock and power sequencing, ETU-based timeout counter configuration, and step-up converter operation across 2.7–6 V supply.
Technical Context
The TDA8007BHL/C3,118 implements a dedicated ISO 7816 UART with automatic T=0/T=1 protocol handling, including character-level parity error detection and retransmission, 1–8 character receive FIFO, and configurable guard time registers. Its independent sequencer manages activation/deactivation sequences per card, while hardware protections monitor short-circuit, overtemperature, and supply faults on VCC1/VCC2/RST1/RST2/I/O1/I/O2 pins.
It integrates a programmable 24-bit ETU timeout counter (TOR1–TOR3 + TOC register) for ATR, WWT, and BGT timing compliance, plus a step-up converter supporting 2.7–6 V input to generate regulated 5 V (65 mA), 3 V (50 mA), or 1.8 V (30 mA) card supplies with controlled slew rate (0.05–0.22 V/μs). Clock generation supports up to 10 MHz output with fXTAL, ½fXTAL, ¼fXTAL, and ⅛fXTAL division.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.7 V to 6.0 V - enables direct battery or wide-input industrial supply integration without external regulators |
| Card supply outputs | 5 V ±5 % / 65 mA max, 3 V ±8 % / 50 mA max, or 1.8 V ±10 % / 30 mA max - supports legacy and modern smart cards simultaneously |
| Crystal frequency | 4 MHz to 20 MHz - allows flexible clock source selection for timing accuracy and EMI optimization |
| ISO UART FIFO depth | 1–8 characters - reduces host CPU interrupt load during high-speed T=1 block transfers |

Pinout & Package
LQFP48 package (7 × 7 × 1.4 mm, SOT313-2); 48-pin quad flat with exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA8007BHL/C4,118 | Fixed non-multiplexed bus interface only; ALE pin not functional; identical pinout and register map | Lacks multiplexed bus auto-detection - requires static address/data separation in 80C51 designs | Select when design uses fixed non-multiplexed bus and ESD-induced ALE mode switching must be avoided |
| TDA8020HN/C1,118 | Single-card interface; no integrated step-up converter; requires external 5 V supply; LQFP64 package | Lower cost for single-card applications but adds external regulator and increases board footprint | Select only for cost-sensitive single-card readers where dual-card capability and wide-input operation are unnecessary |
Compared with TDA8007BHL/C4,118, the TDA8007BHL/C3,118 offers field-upgradable bus configuration and enhanced ESD resilience; versus TDA8020HN/C1,118, it delivers dual-card support, integrated power conversion, and smaller LQFP48 footprint - critical for compact multi-application terminals.

FAQ
What bus configurations does the TDA8007BHL/C3,118 support?
The TDA8007BHL/C3,118 supports both non-multiplexed and multiplexed 8-bit parallel bus interfaces. In non-multiplexed mode, AD0–AD3 select registers while D0–D7 carry data; in multiplexed mode, ALE rising edge triggers internal demultiplexing, allowing direct connection to 80C51 port P0. This dual-mode capability is unique to the /C3 variant - the /C4 version supports non-multiplexed only.
How does the TDA8007BHL/C3,118 handle smart card power sequencing?
The TDA8007BHL/C3,118 implements hardware-controlled activation and deactivation sequences per card via dedicated sequencers. It generates compliant ISO 7816 Class A/B/C voltages (5 V/3 V/1.8 V) with controlled rise/fall times (0.05–0.22 V/μs), monitors VCC1/VCC2 for overcurrent (100 mA trip), and asserts RST1/RST2 with precise timing - all without host MCU intervention.
What is the role of the 24-bit ETU timeout counter in the TDA8007BHL/C3,118?
The 24-bit ETU timeout counter (TOR1–TOR3 + TOC register) in the TDA8007BHL/C3,118 provides hardware-accelerated timing for ISO 7816 protocol events: Answer-to-Reset (ATR), Work Waiting Time (WWT), and Block Guard Time (BGT). It operates independently per card and triggers interrupts on USR register bits TO1/TO2/TO3 - eliminating software timer overhead in real-time smart card stacks.
Can the TDA8007BHL/C3,118 drive synchronous smart cards?
Yes, the TDA8007BHL/C3,118 supports synchronous cards via auxiliary contacts C41/C42 and C81/C82. These pins provide dedicated I/O paths for ISO 7816-3 synchronous protocols, and are controlled through the Power Control Register (PCR) - enabling mixed asynchronous/synchronous card operation within the same reader.
What protection features does the TDA8007BHL/C3,118 include for card interface reliability?
The TDA8007BHL/C3,118 integrates hardware protections including ±6 kV HBM ESD on card-side pins (I/O1/I/O2/VCC1/VCC2/RST1/RST2), short-circuit current limiting (100 mA trip), overtemperature shutdown (PTL flag), and supply supervisor with power-on/power-off reset. Fault conditions are reported in the Hardware Status Register (HSR) and trigger INT pin assertion for immediate host response.
