CY7C63310, CY7C638xx
enCoRe™ II
Low Speed USB Peripheral Controller
1. Features
■ USB 2.0-USB-IF certified (TID # 40000085)
■ enCoRe™ II USB - “enhanced Component Reduction”
❐ Crystalless oscillator with support for an external clock. The
internal oscillator eliminates the need for an external crystal
or resonator.
❐ Two internal 3.3V regulators and an internal USB pull up
resistor
❐ Configurable IO for real world interface without external com-
ponents
■ 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
❐ Supports one control endpoint and two data endpoints
❐ Integrated USB transceiver with dedicated 3.3V regulator for
USB signalling and D– pull up.
■ Enhanced 8-bit microcontroller
❐ Harvard architecture
❐ M8C CPU speed is up to 24 MHz or sourced by an external
clock signal
■ Internal memory
❐ Up to 256 bytes of RAM
❐ Up to eight Kbytes of Flash including EEROM emulation
■ Interface can auto configure to operate as PS/2 or USB
❐ No external components for switching between PS/2 and
USB modes
❐ No General Purpose IO (GPIO) pins required to manage dual
mode capability
■ Low power consumption
❐ Typically 10 mA at 6 MHz
❐ 10 μA sleep
■ In system reprogrammability:
❐ Allows easy firmware update
■ GPIO ports
❐ Up to 20 GPIO pins
❐ 2 mA source current on all GPIO pins. Configurable 8 or
50 mA/pin current sink on designated pins.
❐ Each GPIO port supports high impedance inputs, config-
urable pull up, open drain output, CMOS/TTL inputs, and
CMOS output
❐ Maskable interrupts on all IO pins
■ A dedicated 3.3V regulator for the USB PHY. Aids in signalling
and D– line pull up
■ 125 mA 3.3V voltage regulator powers external 3.3V devices
■ 3.3V IO pins
❐ 4 IO pins with 3.3V logic levels
❐ Each 3.3V pin supports high impedance input, internal pull
up, open drain output or traditional CMOS output
■ SPI serial communication
❐ Master or slave operation
❐ Configurable up to 4 Mbit/second transfers in the master
mode
❐ Supports half duplex single data line mode for optical sensors
■ 2-channel 8-bit or 1-channel 16-bit capture timer registers.
Capture timer registers store both rising and falling edge times.
❐ Two registers each for two input pins
❐ Separate registers for rising and falling edge capture
❐ Simplifies the interface to RF inputs for wireless applications
■ Internal low power wakeup timer during suspend mode:
❐ Periodic wakeup with no external components
■ 12-bit Programmable Interval Timer with interrupts
■ Advanced development tools based on Cypress PSoC® tools
■ Watchdog timer (WDT)
■ Low voltage detection with user configurable threshold
voltages
■ Operating voltage from 4.0V to 5.5V DC
■ Operating temperature from 0–70°C
■ Available in 16 and 18-pin PDIP; 16, 18, and 24-pin SOIC;
24-pin QSOP, and 32-pin QFN packages
■ Industry standard programmer support
