73S8009R-IM/F

Overview

The 73S8009R-IM/F is a dedicated power management integrated circuit designed for smart card applications, functioning as a reader and writer controller. Manufactured by Analog Devices Inc./Maxim Integrated, it integrates necessary voltage regulation and level shifting capabilities within a compact 20-QFN (4x4 mm) package. This component supports standard smart card interface requirements, providing efficient power management solutions for contact-based smart card systems in embedded environments.

Feature Summary

• Integrates smart card reader and writer functionality with dedicated power management
• Provides level shifting and voltage regulation for smart card interfaces
• Designed for compact embedded applications requiring efficient power control

Applications

• Smart card reader devices
• Smart card writer modules
• Contact-based smart card systems

Procurement Notes

Verify the specific suffix 'R' against official datasheets to confirm functional differences from non-R variants. Confirm package dimensions match the 20-QFN (4x4 mm) specification. Check current lifecycle status as this part may be discontinued or subject to limited supply constraints.

Selection Notes

Select this component when a combined power management and smart card interface solution is required in a small form factor. Ensure the application environment supports the thermal characteristics of the QFN package. Verify compatibility with existing smart card protocol requirements before integration.

Part Context

This part belongs to the 73S8009 series of smart card PMICs. It is related to the 73S8009CN-32IM/F, which uses a larger 32-VFQFN package. The 73S8009R-IM/F offers a more compact footprint suitable for space-constrained designs compared to its 32-pin counterpart.

Replacement Considerations

The 73S8009CN-32IM/F is a related part but utilizes a 32-VFQFN package instead of the 20-QFN. Direct pin-to-pin replacement is not possible due to the different package sizes and pin counts.
