73S8009C-32IMR/F

Overview

The 73S8009C-32IMR/F is a specialized power management integrated circuit (PMIC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a smart card reader and writer interface controller, designed to facilitate communication with smart cards in compliance with ISO/IEC 7816 standards. The component is housed in a 32-pin QFN package measuring 5x5 mm, suitable for compact electronic designs requiring dedicated I/O control for smart card applications.

Feature Summary

• Provides dedicated interface control for smart card reading and writing operations
• Ensures compliance with ISO/IEC 7816 standards for smart card communication
• Integrates power management capabilities within a single specialized PMIC solution

Applications

• Smart card reader devices
• Smart card writer systems
• Embedded I/O controllers requiring smart card support

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing from distributors. Confirm the manufacturer designation matches Analog Devices or Maxim Integrated, as historical branding may vary. Ensure the 32-QFN package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a dedicated PMIC is required for smart card interfaces rather than general-purpose logic. Consider the 32-pin QFN form factor for space-constrained layouts. Evaluate compatibility with existing system voltage levels and ensure design adherence to ISO/IEC 7816 timing specifications provided in official application notes.

Part Context

This part belongs to the 73S8009 series of smart card interface ICs from Maxim Integrated. It serves as a specialized solution for managing power and data lines for smart cards, distinct from general microcontrollers or standard interface chips. The series supports various packaging options including QFN variants for different board size constraints.

Replacement Considerations

Check for other variants within the 73S8009 family, such as the 73S8009CN-32IM/F, which may offer identical functionality with different packaging or temperature grades. Verify pin-to-pin compatibility and electrical specifications before substituting with any alternative part numbers.
