描述 Description

The ATSHA206A is a Microchip CryptoAuthenticationTM?device primarily dedicated to consumable applications and ecosystem control. The device has five slots and a preassigned configuration that reduces development time and the time-to-market for specific use cases. The ATSHA206A is a true two-wire device that is powered parasitically through the single-wire interface signal. The device comes in a number of custom packaging solutions and has a built-in decoupling capacitor providing an attractive solution for a wide variety of applications where the accessory may or may not require an actual PCB and the space is limited.
