enCoRe™ USB - enhanced Component Reduction
❐
Internal oscillator eliminates the need for an external crystal
or resonator
❐
Interface can auto-configure to operate as PS/2 or USB with-
out the need for external components to switch between
modes (no General Purpose I/O [GPIO] pins needed to man-
age dual mode capability)
❐
Internal 3.3V regulator for USB pull-up resistor
❐
Configurable 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.
