Freescale Semiconductor, Inc.
• USB device mode
• Suspend mode/low power
• Includes an on-chip full-speed (12 Mbps) and low-speed (1.5 Mbps) transceiver
• Compatible with systems powered from:
• Programmable event timers for flexibility and better compatibility with future udpates to the standards
• Compliant with the latest industry standard specification, USB Battery Charging Specification, Revision 1.1
• 5V regulator input typically provided by USB VBUS power
• 3.3V regulated output powers on-chip USB transceiver
• Output pin from regulator can be used to power external board components and source up to 120mA
• Eliminates cost of external LDO
• 3.3V regulated output can power MCU main power supply
• Master and slave mode
• Full-duplex, three-wire synchronous transfers
• Programmable transmit bit rate
• Double-buffered transmit and receive data registers
• Serial clock phase and polarity options
• Slave select output
• Mode fault error flag with CPU interrupt capability
• Control of SPI operation during wait mode
• Selectable MSB-first or LSB-first shifting
• Programmable 8-bit or 16-bit data transmission length
• Receive data buffer hardware match feature
• 64-bit FIFO mode for high speed transfers of large amounts of data
• Support for both transmit and receive by DMA
• Supports enhanced-host-controller interface (EHCI)
• Allows direct connection of FS/LS devices without an OHCI/UHCI companion controller
• Supported by Linux and other commercially available operating systems
• Full-speed operation via the on-chip transceiver
• Supports one upstream facing port
• Supports four programmable, bidirectional USB endpoints, including endpoint 0
• As host, firmware can suspend individual devices or the entire USB and disable chip clocks for low-power
• Device supports low-power suspend
• Remote wake-up supported for host and device
• Integrated with the processor’s low power modes
• Rechargable battery
• Non-rechargable battery
• External 3.3v LDO regulator powered from USB or
• Directly from USB using internal regulator
