enCoRe⢠II
Low-Speed USB Peripheral Controller
1.0 Features
⢠enCoRe II USBââenhanced Component Reductionâ
â Crystalless oscillator with support for an external
crystal or resonator. The internal oscillator
eliminates the need for an external crystal or
resonator
â Internal 3.3V regulator and internal USB pull-up
resistor
â Configurable IO for real-world interface without
external components
⢠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
â Supports one control endpoint and two data
endpoints
â Integrated USB transceiver
⢠Enhanced 8-bit microcontroller
â Harvard architecture
â M8C CPU speed can be up to 24 MHz or sourced by
an external crystal, resonator, or signal
⢠Internal memory
â Up to 256 bytes of RAM
â Up to eight Kbytes of Flash including EEROM
emulation
⢠Interface can auto-configure to operate as PS/2 or USB
â No external components for switching between PS/2
and USB modes
â No GPIO pins needed to manage dual-mode
capability
⢠Low power consumption
â Typically 10 mA at 6 MHz
â 10-µA sleep
⢠In-system re-programmability
â Allows easy firmware update
⢠General-purpose I/O ports
â Up to 36 General Purpose I/O (GPIO) pins
â High current drive on GPIO pins. Configurable 8- or
50-mA/pin current sink on designated pins
â Each GPIO port supports high-impedance inputs,
configurable pull-up, open drain output, CMOS/TTL
inputs, and CMOS output
â Maskable interrupts on all I/O pins
⢠125-mA 3.3V voltage regulator can power external 3.3V
devices
⢠3.3V I/O pins
â 4 I/O pins with 3.3V logic levels

â Master or slave operation
â Configurable up to 2-Mbit/second transfers
â Supports half duplex single data line mode for
optical sensors
⢠2-channel 8-bit or 1-channel 16-bit capture timer.
Capture timers registers store both rising and falling
edge times
â Two registers each for two input pins
â Separate registers for rising and falling edge capture
â Simplifies interface to RF inputs for wireless
applications
⢠Internal low-power wake-up timer during suspend
mode
â Periodic wake-up with no external components
⢠Programmable Interval Timer interrupts
⢠Reduced RF emissions at 27 MHz and 96 MHz
⢠Advanced development tools based on Cypress
MicroSystems PSoC⢠tools
⢠Watchdog timer (WDT)
⢠Low-voltage detection with user-configurable
threshold voltages
⢠Improved output drivers to reduce EMI
