73S1209F-68M/F/P1

Overview

The 73S1209F-68M/F/P1 is a self-contained smart card reader integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-bit microcontroller based on the 8051 architecture with a Serial High-Speed (HST) interface. The device operates within a supply voltage range of 2.7V to 6.5V and supports a maximum clock frequency of 24 MHz. It is housed in a 68-QFN package measuring 8x8 mm.

Feature Summary

Integrates an 8051-based microcontroller for self-contained smart card operations
Supports Serial High-Speed (HST) interface communication
Operates across a wide supply voltage range from 2.7V to 6.5V

Applications

Smart card reader systems
Secure identification devices
Payment terminal interfaces

Procurement Notes

Verify the specific suffix 'F' and package variant 'P1' against the manufacturer's current product status, as legacy Maxim Integrated components may have transitioned statuses or packaging updates. Confirm RoHS compliance and availability through authorized distributors, ensuring the part number matches the exact 68-QFN specification required for your design.

Selection Notes

Select this component when a complete, standalone smart card reading solution is required without external host processing overhead. The integrated 8051 core handles protocol management, while the HST interface allows for high-speed data transfer. Ensure the PCB layout accommodates the 68-QFN 8x8mm footprint and that the system power supply remains stable within the 2.7V to 6.5V operating window.

Part Context

This part belongs to the DS24xx/73S series of smart card controllers from Maxim Integrated, now part of Analog Devices. These ICs are designed to simplify smart card integration by embedding the necessary microcontroller and interface logic into a single package, reducing board space and component count compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct pin-compatible alternatives within the 73S1209 family or consult Analog Devices for current lifecycle status and recommended replacements if this specific suffix is discontinued.
