SHA104-TFLXAUTHS-CZ-HV

Overview

The SHA104-TFLXAUTHS-CZ-HV is a pre-provisioned secure authentication integrated circuit from Microchip Technology's CryptoAuthentication family. Designed for low-cost applications, it supports symmetric and asymmetric authentication protocols to establish trust in electronic ecosystems. The device operates within a voltage range of 1.65V to 5.5V and functions across an industrial temperature range of -40°C to +105°C. It utilizes a Single Wire Interface (SWI) for communication and is housed in a UDFN package. This component is specifically targeted at consumable and disposable accessory applications requiring robust security without complex provisioning.

Feature Summary

• Pre-provisioned for immediate deployment in symmetric authentication scenarios
• Supports both symmetric and asymmetric cryptographic authentication methods
• Optimized for low-cost disposable and accessory product integration

Applications

• Consumable cartridge authentication
• Disposable medical device verification
• Accessory ecosystem trust establishment

Procurement Notes

Verify the specific suffix 'HV' against official Microchip documentation to confirm exact temperature grade and package variant specifications. Ensure the pre-provisioned key data matches your system requirements, as this parameter cannot be altered post-manufacture. Confirm interface compatibility with the host controller's Single Wire Interface implementation before finalizing procurement.

Selection Notes

Select this component when a cost-effective, pre-configured solution for accessory authentication is required. It is suitable for designs where asymmetric capabilities are needed but provisioning complexity must be minimized. Consider the SWI interface constraints and operating voltage range relative to the target system architecture.

Part Context

This part belongs to the SHA104 series within Microchip's CryptoAuthentication portfolio. These devices provide hardware-based security solutions for protecting intellectual property and verifying authenticity in connected devices. The SHA104 series is distinct from other microcontrollers by focusing solely on secure element functions rather than general-purpose processing.

Replacement Considerations

Consult Microchip's official cross-reference guides for verified substitutes. Generic crypto-authentication ICs may not offer identical pre-provisioning or interface compatibility.
