Product details
Overview
TDA8029HL/C207 from NXP Semiconductors is a single-chip, low-power smart card reader IC integrating an 80C51 microcontroller (16 kB ROM, 256 B RAM, 512 B XRAM), ISO/IEC 7816-3 UART with T=0/T=1 protocol support, programmable card clock up to 20 MHz, and DC-to-DC converter for 2.7–6.0 V input. It delivers full card activation/deactivation sequencing, ETU timing control, and embedded firmware for portable EMV-compliant readers.
For engineers reviewing the TDA8029HL/C207 datasheet, TDA8029HL/C207 pinout, TDA8029HL/C207 application, or TDA8029HL/C207 equivalent, this device serves as a complete, self-contained smart card interface solution requiring no external microcontroller - ideal for battery-powered terminals, point-of-sale peripherals, and secure identity readers where supply voltage flexibility, ESD robustness (6 kV on card contacts), and low-power shutdown (<20 µA) are critical.
Technical Context
The TDA8029HL/C207 implements a dedicated 80C51FB core with enhanced UART, 24-bit ETU counter for ATR and T=1 Block Guard Time, and integrated analog sequencer for ISO 7816 card power management. Its hardware-accelerated UART supports automatic convention processing, character-level error detection, and variable baud rate generation via Timer 2.
It integrates a configurable DC-to-DC converter (doubler/tripler/follower mode), controlled VCC ramp-up/down (0.05–0.22 V/µs), and shut-down input (SDWN_N) enabling ultra-low-power operation. The chip supports both 5 V and 3 V smart cards with programmable current limits (up to 65 mA) and overload detection at 100 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card reader IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7412AU | ARM Cortex-M0+ core, NFC + contact reader combo, EMVCo 4.3c certified; no integrated DC-to-DC converter | Supports contactless (ISO 14443) and contact interfaces simultaneously; requires external 3.3 V supply | Choose for dual-interface (contact + NFC) terminals needing latest EMVCo 4.3c compliance - not a drop-in replacement due to different power architecture and pinout |
| TDA8035HN/C1 | Same 80C51 core but with extended temperature range (−40 °C to +105 °C); identical pinout and firmware compatibility | Targeted for automotive-grade applications requiring AEC-Q100 qualification and higher thermal margin | Choose when operating ambient exceeds +90 °C or AEC-Q100 compliance is mandatory - otherwise functionally interchangeable with TDA8029HL/C207 |
Compared with PN7412AU, TDA8029HL/C207 offers lower system cost and simpler power design but lacks NFC; compared with TDA8035HN/C1, it provides identical functionality at lower thermal grade - making TDA8029HL/C207 optimal for commercial portable readers where cost and integration density are prioritized over automotive qualification.

FAQ
What is the maximum crystal frequency supported by the TDA8029HL/C207?
The TDA8029HL/C207 supports an external crystal frequency up to 27 MHz on XTAL1, with typical operation at 20 MHz to enable full-speed 20 MHz card clock generation. When VDD < 3.0 V, the maximum crystal frequency is reduced to 16 MHz to maintain timing integrity across the supply range.
Does the TDA8029HL/C207 require external firmware programming?
No - the TDA8029HL/C207 ships with factory-programmed 16 kB ROM containing standard embedded software compliant with ISO/IEC 7816-3 and EMVCo 4.3 (for TDA8029HL/C2 variant). Application-specific customization is possible via the on-chip XRAM and user-accessible registers, but no external flash or bootloader is needed for basic operation.
How does the TDA8029HL/C207 handle card presence detection?
The TDA8029HL/C207 uses the PRES pin (Pin 8) as a dedicated active-HIGH card presence input. It interfaces directly with a normally open mechanical switch on the card slot - no external pull-up or pull-down resistors are required, and internal circuitry automatically debounces and validates insertion events before initiating activation sequencing.
Can the TDA8029HL/C207 drive both 3 V and 1.8 V smart cards?
Yes - the TDA8029HL/C207 dynamically configures its VCC output to 1.8 V (1.62–1.98 V), 3.0 V (2.75–3.25 V), or 5.0 V (4.6–5.3 V) based on ATR response and protocol negotiation. It delivers up to 30 mA at 1.8 V, 65 mA at 3 V, and 65 mA at 5 V, with built-in overload detection at 100 mA to protect against short circuits.
What communication interface does the TDA8029HL/C207 use to connect to the host processor?
The TDA8029HL/C207 communicates with the host processor via a standard full-duplex asynchronous serial interface using P30/RX (input) and P31/TX (output) pins. Baud rate is programmable in firmware, supporting common rates including 9600, 19200, 38400, and 115200 bps - no additional level-shifting or protocol translation is required.
