enCoRe™ USB Combination Low-Speed
USB and PS/2 Peripheral Controller
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
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
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

SPI serial communication block
Master or slave operation
2 Mbit/s transfers
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)
Low-voltage Reset at 3.75V
Internal brown-out reset for suspend mode
Improved output drivers to reduce EMI
