Functional Description
Cypress has reinvented its leadership position in the low-speed USB market with a new family of innovative microcontrollers. Introducing...enCoRe USB-"enhanced Component Reduction." Cypress has leveraged its design expertise in USB solutions to create a new family of low-speed USB microcontrollers that enables peripheral developers to design new products with a minimum number of components.
At the heart of the enCoRe USB technology is the breakthrough design of a crystalless oscillator. By integrating the oscillator into our chip, an external crystal or resonator is no longer needed. We have also integrated other external components commonly found in low-speed USB applications such as pull-up resistors, wake-up circuitry, and a 3.3V regulator. All of this adds up to a lower system cost.
The CY7C637xx is an 8-bit RISC one-time-programmable (OTP) microcontroller. The instruction set has been optimized specifically for USB and PS/2 operations, although the microcontrollers can be used for a variety of other embedded applications.
