7.6 USB
PSoC includes a dedicated Full-Speed (12 Mbps) USB 2.0
transceiver supporting all four USB transfer types: control,
interrupt, bulk, and isochronous. PSoC Creator provides full
configuration support. USB interfaces to hosts through two
dedicated USBIO pins, which are detailed in the
Routing”
USB includes the following features:
Document Number: 001-66236 Rev. *A
Eight unidirectional data endpoints
One bidirectional control endpoint 0 (EP0)
Shared 512-byte buffer for the eight data endpoints
Dedicated 8-byte buffer for EP0
Two memory modes
Internal 3.3 V regulator for transceiver
Internal 48 MHz oscillator that auto locks to USB bus clock,
requiring no external crystal for USB (USB equipped parts only)
