MPC8309 PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 0
— Supports 1-/4-bit SD and SDIO modes, 1-/4-bit modes
— Supports block sizes of 1 ~ 4096 bytes
Universal serial bus (USB) dual-role controller
— Designed to comply with Universal Serial Bus Revision 2.0 Specification
— Supports operation as a stand-alone USB host controller
— Supports operation as a stand-alone USB device
— Supports high-speed (480-Mbps), full-speed (12-Mbps), and low-speed (1.5-Mbps) operations.
FlexCAN module
— Full implementation of the CAN protocol specification version 2.0B
— Up to 64 flexible message buffers of zero to eight bytes data length
— Powerful Rx FIFO ID filtering, capable of matching incoming IDs
— Selectable backwards compatibility with previous FlexCAN module version
— Programmable loop-back mode supporting self-test operation
— Global network time, synchronized by a specific message
— Independent of the transmission medium (an external transceiver is required)
— Short latency time due to an arbitration scheme for high-priority messages
Dual I
— Two-wire interface
— Multiple-master support
— Master or slave I
— On-chip digital filtering rejects spikes on the bus
— I
DMA Engine1
— Support for the DMA engine with the following features:
— Support for scatter/gather DMA processing
IO Sequencer
– Up to 133 Mbps data transfer for SD/SDIO/MMC cards using 4 parallel data lines
Low speed is only supported in host mode.
– Sixteen DMA channels
– All data movement via dual-address transfers: read from source, write to destination
– Transfer control descriptor (TCD) organized to support two-deep, nested transfer operations
– Channel activation via one of two methods (for both the methods, one activation per
– Support for fixed-priority and round-robin channel arbitration
– Channel completion reported via optional interrupt requests

execution of the minor loop is required):
– Explicit software initiation
– Initiation via a channel-to-channel linking mechanism for continuous transfers
C interfaces
(independent channel linking at end of minor loop and/or major loop)
