Product details
Overview
TDA8029HL/C206,118 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 EMVCo 4.3 compliance for portable payment terminals and secure identity readers.
For engineers reviewing the TDA8029HL/C206,118 datasheet, TDA8029HL/C206,118 pinout, TDA8029HL/C206,118 application, or TDA8029HL/C206,118 equivalent, this page provides verified technical context, validated pin functions, confirmed power modes (shut-down current ≤20 μA), real-world timing parameters (e.g., 11.8 ETU min inter-character delay in T=0), and direct alternative options for smart card interface design.
Technical Context
The TDA8029HL/C206,118 embeds a hardened 80C51FB core with enhanced UART, dedicated 24-bit ETU counter for ATR and T=1 block guard time, and independent sequencer for automatic card activation/deactivation. Its ISO 7816 UART supports MOVX-accessible register control, character-level error handling, and variable baud rate generation via Timer 2.
Power management includes three hardware-controlled reduction modes: shut-down (≤20 μA), power-down (≤110 μA), and sleep (≤800 μA), enabled by SDWN_N input and internal supply supervisor. Card voltage (VCC) is generated with controlled slew rate (0.05–0.22 V/μs) and supports 1.8 V, 3 V, and 5 V cards with current limits up to 65 mA.

FAQ
What is the maximum crystal frequency supported by the TDA8029HL/C206,118?
The TDA8029HL/C206,118 supports an external crystal frequency of up to 27 MHz on XTAL1, with typical operation at 20 MHz for full-speed card clock generation. The internal oscillator architecture allows stable operation across the full −40 °C to +90 °C ambient temperature range, and the device remains functional at lower frequencies (down to DC) in Power-down mode. This 27 MHz limit is specified in Table 1 of the official datasheet Rev. 3.4.
Does the TDA8029HL/C206,118 support both T=0 and T=1 smart card protocols?
Yes, the TDA8029HL/C206,118 natively supports both T=0 and T=1 protocols per ISO/IEC 7816-3, including automatic convention processing, character-level error management, and protocol-specific guard times (16 ETU for T=0, 22 ETU for T=1). Its dedicated UART and 24-bit ETU counter ensure hardware-accelerated compliance - confirmed in Section 2 "Features and benefits" and Section 8.9 of the datasheet.
What is the minimum inter-character delay for T=0 protocol on the TDA8029HL/C206,118?
The TDA8029HL/C206,118 guarantees a minimum inter-character delay of 11.8 ETU in T=0 protocol mode, as explicitly stated in Table 1 "Quick reference data" and confirmed in Section 2's feature list. This value meets EMVCo 4.3 timing requirements for legacy card compatibility and is enforced by the dedicated ETU counter and sequencer hardware.
How does the shut-down mode function on the TDA8029HL/C206,118?
The TDA8029HL/C206,118 enters shut-down mode when the SDWN_N pin is driven LOW, reducing total supply current to ≤20 μA at VDD = 3.3 V. In this state, all internal circuitry (including the oscillator and microcontroller) is disabled except for wake-up logic on INT1_N, RX, and INT0_N. The datasheet specifies this behavior in Section 4 "Quick reference data" and Section 8.14 "Power reduction modes".
Is external memory required to run firmware on the TDA8029HL/C206,118?
No, the TDA8029HL/C206,118 contains 16 kB of on-chip ROM, 256 bytes of RAM, and 512 bytes of XRAM - sufficient to execute the standard embedded software referenced in AN10207 without external memory. The 80C51FB core supports MOVX instructions for XRAM access, and the datasheet confirms full static operation with no external bus interface required for basic smart card reader functionality.
