enCoRe⢠USB Combination Low-Speed
USB and PS/2 Peripheral Controller
1.0 Features
⢠enCoRe⢠USB - enhanced Component Reduction
â Internal oscillator eliminates the need for an external
crystal or resonator
â Interface can auto-configure to operate as PS/2 or
USB without the need for external components to
switch between modes (no General Purpose I/O
[GPIO] pins needed to manage dual mode capability)
â Internal 3.3V regulator for USB pull-up resistor
â 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, game-
pads, joysticks, and many others.
⢠USB Specification Compliance
â Conforms to USB Specification, Version 2.0
â Conforms to USB HID Specification, Version 1.1
â Supports one low-speed USB device address and
three data endpoints
â Integrated USB transceiver
â 3.3V regulated output for USB pull-up resistor
⢠8-bit RISC microcontroller
â Harvard architecture
â 6-MHz external ceramic resonator or internal clock
mode
