Description
The Microchip CryptoAuthentication™ devices are often used in product accessory or product ecosystem management in a wide variety of markets. These include battery authentication, disposable cartridge authentication or similar applications. When used in these applications, the only electronic device that is required on the cartridge is often the authentication device. For this reason, the 3-lead Contact package was developed to eliminate the need for a PCB board. The package itself is mounted by attaching the backside of the package to the item being authenticated with the exposed pads facing outward. Connection to the electrical contacts of the authentication device is made using mechanical pressure against the compression connectors or pogo pins (i.e., unsoldered connections).
