• Manufacturer Part Number: CY8C36_1105
• Description: Programmable System-on-Chip (PSoC) Multiply and divide instructions
• Manufacturer: CYPRESS [Cypress Semiconductor]

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:
