Cypress Perform

The enCoRe II (CY7C63310, CY7C638xx) is programmable low speed USB controller. enCoRe II eliminates the external crystal or resonator, pull up resistors, wakeup circuitry and 3.3V regulator to reduce the overall system cost. enCoRe II features a wide selection of I/O (up to 20 GPIOs) and memory (up to 8 kB of flash for user code and 256 Bytes of RAM) options targeted for USB applications.
