Infineon/CYPRESS CY7C63813-SXC

Cypress has reinvented its leadership position in the low - speed USB market with a new family of innovative microcontrollers. Introducing enCoRe II USB - “enhanced Component Reduction.” The enCoRe II USB technology builds on the enCoRe family. The enCoRe family has an integrated oscillator that eliminates the external crystal or resonator, reducing overall cost. Also integrated into this chip are other external components commonly found in low - speed USB applications, such as pull up resistors, wakeup circuitry, and a 3.3V regulator. Integrating these components reduces the overall system cost.

The enCoRe II is an 8 - bit Flash programmable microcontroller with an integrated low - speed USB interface. The instruction set is optimized specifically for USB and PS/2 operations, although the microcontrollers may be used for a variety of other embedded applications.

The enCoRe II features up to 20 General Purpose IO (GPIO) pins to support USB, PS/2, and other applications. Each GPIO port supports high impedance inputs, configurable pull up, open drain output, CMOS/TTL inputs, and CMOS output with up to five pins that support a programmable drive strength of up to 50 mA sink current. GPIO Port 1 features four pins that interface at a voltage level of 3.3 volts. Additionally, each IO pin may be used to generate a GPIO interrupt to the microcontroller.

The enCoRe II features an internal oscillator. With the presence of USB traffic, the internal oscillator may be set to precisely tune to USB timing requirements (24 MHz ±1.5%). Optionally, an external 12 MHz or 24 MHz clock is used to provide a higher precision reference for USB operation. The clock generator provides the 12 MHz and 24 MHz clocks that remain internal to the microcontroller. The enCoRe II also has a 12 - bit programmable interval timer and a 16 - bit Free Running Timer with Capture Timer registers. In addition, the enCoRe II includes a Watchdog timer and a vectored interrupt controller.

The enCoRe II has up to eight Kbytes of Flash for user code and up to 256 bytes of RAM for stack space and user variables.
