DS8024-RJX+

Specialized Overview

The DS8024-RJX+ is a smart card interface IC designed for ISO 7816, EMV, and GSM 11-11 applications. It operates within a temperature range of -40°C to +85°C in a 28-pin TSSOP package. The device supports 3.0V and 5.0V smart cards with internal voltage generation providing up to 80mA at 5V or 65mA at 3V. Digital supply voltage (VDD) ranges from 2.7V to 6.0V, while the charge-pump supply (VDDA) ranges from 3.0V to 6.0V. Active current consumption reaches 215mA for 5V cards and 100mA for 3V cards. The I/O lines support a maximum frequency of 1MHz, and the clock output supports frequencies up to 10MHz.

Specialized Feature Summary

• Analog interface and level shifting for IC card communication
• Internal IC card supply-voltage generation with high-current capability
• Automatic card activation and deactivation controlled by dedicated internal sequencer
• Flexible card clock generation supporting external crystal frequency division

Specialized Applications

• Set-Top Box Conditional Access
• POS Terminals
• Automated Teller Machines
• PIN Pads

Specialized Procurement Notes

Verify the component matches the specific 28-pin TSSOP package configuration. Confirm that the lead-free designation aligns with RoHS compliance requirements for your assembly process. Ensure the operating temperature range meets the environmental specifications of the target application before finalizing procurement.

Specialized Selection Notes

Select this component when a pin-for-pin replacement for the NXP TDA8024 is required. Consider the DS8113 if the design demands lower active- and stop-mode power consumption for 1.8V smart card support. Verify that the host controller voltage levels are compatible with the VDD supply range specified for this interface.

Specialized Part Context

This part belongs to the Maxim Integrated DS8024 family of smart card interfaces. It serves as an analog front-end for readers requiring compatibility with major global standards. The RJX suffix specifically denotes the 28-pin Thin Shrink Small Outline Package variant, distinguishing it from the standard SO package options available in the series.

Specialized Replacement Considerations

The DS8024-RJX+ is a direct drop-in replacement for the NXP TDA8024. For designs requiring reduced power consumption, the DS8113 is the recommended alternative.
