CY7C63310, CY7C638xx
enCoRe™ II
Low Speed USB Peripheral Controller
enCoRe™ II Low Speed USB Peripheral Controller
■ GPIO ports
Features
❐ Up to 20 GPIO pins
■ USB 2.0-USB-IF certified (TID # 40000085)
❐ 2 mA source current on all GPIO pins. Configurable 8 or
50 mA/pin current sink on designated pins.
■ 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.
❐ Each GPIO port supports high impedance inputs,
configurable pull-up, open drain output, CMOS/TTL inputs,
and CMOS output
❐ Two internal 3.3 V regulators and an internal USB Pull-up
❐ Maskable interrupts on all I/O pins
resistor
■ A dedicated 3.3 V regulator for the USB PHY. Aids in signalling
and D– line pull-up
❐ Configurable I/O for real world interface without external
components
■ 125 mA 3.3 V voltage regulator powers external 3.3 V devices
■ 3.3 V I/O pins
■ 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
❐ 4 I/O pins with 3.3 V logic levels
❐ Each 3.3 V pin supports high impedance input, internal
pull-up, open drain output or traditional CMOS output
■ SPI serial communication
❐ Integrated USB transceiver with dedicated 3.3 V regulator for
USB signalling and D– pull-up.
❐ Master or slave operation
❐ Configurable up to 4 Mbps transfers in the master mode
❐ Supports half duplex single data line mode for optical sensors
■ Enhanced 8-bit microcontroller
❐ Harvard architecture
■ 2-channel 8-bit or 1-channel 16-bit capture timer registers.
Capture timer registers store both rising and falling edge times.
❐ M8C CPU speed is up to 24 MHz or sourced by an external
clock signal
❐ Two registers each for two input pins
■ Internal memory
❐ 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)
❐ 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 I/O (GPIO) pins required to manage
dual mode capability
■ Low power consumption
❐ Typically 10 mA at 6 MHz
❐ 10 A sleep
■ Low-voltage detection with user configurable threshold
voltages
■ Operating voltage from 4.0 V to 5.5 V DC
■ Operating temperature from 0 °C–70 °C
■ In system reprogrammability
❐ Allows easy firmware update
■ Available in 18-pin PDIP; 16, 18, and 24-pin SOIC; 24-pin
QSOP, and 24-pin and 32-pin QFN Sawn packages
■ Industry standard programmer support
