Microcontrollers

Unlike memory products, microcontrollers need a card operating system (COS) to manage their on-board resources just like a personal computer requires an operating system i.e. Windows XGP. Keystone can provide microcontroller chips which offer the absolute highest security available today as defined by international criteria and standards for chip devices. They are the perfect solution for public key cryptography, secure network log-on and authentication for e-commerce transactions.
