TDA8037TT/C1J

Specialized Overview

The TDA8037TT/C1J is a low-power contact smart card interface IC designed for the 3 V supply domain. It provides comprehensive card protection including thermal and short-circuit detection, ESD protection exceeding 8 kV, and supply supervision. The device operates with a supply voltage (VDD) of 3 V to 3.6 V and delivers a regulated 3 V card supply (VCC). Key electrical parameters include a shutdown current of 250 µA typ., an active no-load current of 5 mA typ., and a maximum VCC output current of 65 mA. It supports external clock inputs up to 20 MHz and features three protected half-duplex bidirectional I/O lines.

Specialized Feature Summary

• Provides enhanced security through integrated thermal protection, short-circuit detection on all contacts, and high-level ESD protection.
• Enables easy integration via software compatibility with previous generations and automatic activation/deactivation sequences triggered by hardware faults or software commands.
• Supports parallel operation of multiple devices using a dedicated Chip Select input and offers flexible clock generation from external sources.

Specialized Applications

• Pay TV systems
• Electronic payment terminals
• Identification cards readers
• Banking IC card readers

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Ensure that the selected variant matches the required pin configuration and environmental specifications for the target application design.

Specialized Selection Notes

Select the TDA8037TT variant for applications requiring a TSSOP16 package. Consider the SO28 version if footprint compatibility with the legacy TDA8024T is required or if additional control pins like Chip Select are needed for multi-device setups.

Specialized Part Context

The TDA8037 serves as the cost-efficient successor to the established TDA8035 contact smart card reader IC. It maintains functional compatibility while optimizing power consumption in the 3 V domain, making it suitable for modern power-efficient contact reader designs.

Specialized Replacement Considerations

The TDA8037 is explicitly documented as the successor to the TDA8035. It is also software compatible with the TDA8024 and TDA8034. Designers should verify pinout differences when migrating from these older models.
