73S8023C-IMR/F

Overview

The 73S8023C-IMR/F is a specialized smart card interface integrated circuit manufactured by Analog Devices Inc. (Maxim Integrated). Designed for set-top box applications, this component operates within a supply voltage range of 2.7 V to 3.6 V and draws an operating supply current of 4.9 mA. It features seven I/Os and is housed in a 32-QFN (5x5) package. The device supports surface mount mounting and functions as a dedicated interface solution for smart card readers and writers.

Feature Summary

• Provides dedicated smart card interface functionality for embedded systems
• Supports stable I/O performance across the specified low-voltage operating range
• Designed specifically for integration into set-top box architectures

Applications

• Set-top boxes
• Smart card readers
• Smart card writers

Procurement Notes

Verify the specific suffix IMR/F against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the design environment supports the 2.7 V to 3.6 V supply range and that thermal requirements for the 32-QFN package are met. Confirm availability status with authorized distributors as product lifecycles may vary.

Selection Notes

Select this component when a dedicated smart card interface is required for set-top box designs. It is suitable for systems operating at 2.7 V that demand stable I/O performance. Consider the 32-QFN package size and the 4.9 mA operating current when evaluating power and space constraints relative to alternative interface solutions.
