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 without the need for external components to 

switch between modes (no General Purpose I/O 

[GPIO] pins needed to manage 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

Four 8-bit Input Capture registers

Two registers each for two input pins

Capture timer setting with five prescaler settings

Separate registers for rising and falling edge capture

Simplifies interface to RF inputs for wireless 

applications

Internal low-power wake-up timer during suspend 

mode

Periodic wake-up with no external components

Optional 6-MHz internal oscillator mode

Allows fast start-up from suspend mode

Watchdog Reset (WDR)
