Features
• enCoRe™ USB - enhanced Component Reduction
¡ªInternal oscillator eliminates the need for an external crystal or resonator
¡ªInterface can auto-configure to operate as PS/2 or USB without the need for external components to switch between
modes (no GPIO pins needed to manage dual mode capability)
¡ªInternal 3.3V regulator for USB pull-up resistor
¡ªConfigurable GPIO for real-world interface without external components
• Flexible, cost-effective solution for applications that combine PS/2 and low-speed USB, such as mice, gamepads,
joysticks, and many others.
