Low-Speed USB Peripheral Controller 40-Pin PDIP

Cypress has reinvented its leadership position in the lowspeed USB market with a new family of innovative microcontrollers. Introducing enCoRe II USB - “enhanced Component Reduction.” Cypress has leveraged its design expertise in USB solutions to advance its family of low-speed USB microcontrollers, which enable peripheral developers to design new products with a minimum number of components. The enCoRe II USB technology builds on to 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 pullup resistors, wake-up circuitry, and a 3.3V regulator. All of this adds up to a lower system cost. The enCoRe II is an 8-bit Flash-programmable microcontroller with integrated low-speed USB interface. 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.
