enCoRe™ USB Combination Low-Speed
USB and PS/2 Peripheral Controller
Features
■ 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.
■ USB Specification Compliance
❐ Conforms to USB Specification, Version 2.0
❐ Conforms to USB HID Specification, Version 1.1
❐ Supports one low-speed USB device address and three data
endpoints
❐ Integrated USB transceiver
❐ 3.3V regulated output for USB pull-up resistor
■ 8-bit RISC microcontroller
❐ Harvard architecture
❐ 6-MHz external ceramic resonator or internal clock mode
❐ 12-MHz internal CPU clock
❐ Internal memory
❐ 256 bytes of RAM
❐ 8 Kbytes of EPROM
❐ Interface can auto-configure to operate as PS/2 or USB
❐ No external components for switching between PS/2 and
USB modes
❐ No GPIO pins needed to manage dual mode capability
■ I/O ports
❐ Up to 16 versatile GPIO pins, individually configurable
❐ High current drive on any GPIO pin: 50 mA/pin current sink
