The HC1206 is a low profile, surface-mount component in the MICRF family of devices from Microchip. It is a 3V antifuse device, specifically designed to support MCU or applications that require controlled change detection to store critical data, such as unlocking codes or unique ID numbers. The device is extremely small and thin, measuring just 0.5mm x 0.5mm with a 0.125mm height profile. It has a 6-pin package, including an active output and enable, while a 100 ohm adjustable resistive value allows the user to set the output voltage. The device is ideal for a variety of applications, featuring a high-impedance input pin and small packages. It can be used in battery modules, tamper detection, or circuit protection. Additionally, features such as very low standby/active current, high tolerance for harsh environments, and high reliability make it an excellent choice for a wide range of applications.
