Overview
— Can operate as a stand-alone USB host controller
– USB root hub with one downstream-facing port
– Enhanced host controller interface (EHCI) compatible
– High-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operations
— External PHY with UTMI, serial and UTMI+ low-pin interface (ULPI)
Local bus controller (LBC)
— Multiplexed 32-bit address and data operating at up to 133 MHz
— Eight chip selects for eight external slaves
— Up to eight-beat burst transfers
— 32-, 16-, and 8-bit port sizes controlled by an on-chip memory controller
— Three protocol engines on a per chip select basis:
– General-purpose chip select machine (GPCM)
– Three user-programmable machines (UPMs)
– Dedicated single data rate SDRAM controller
— Parity support
— Default boot ROM chip select with configurable bus width (8-, 16-, or 32-bit)
Programmable interrupt controller (PIC)
— Functional and programming compatibility with the MPC8260 interrupt controller
— Support for 8 external and 35 internal discrete interrupt sources
— Support for 1 external (optional) and 7 internal machine checkstop interrupt sources
— Programmable highest priority request
— Four groups of interrupts with programmable priority
— External and internal interrupts directed to host processor
— Redirects interrupts to external INTA pin in core disable mode.
— Unique vector number for each interrupt source
Dual industry-standard I2C interfaces
— Two-wire interface
— Multiple master support
— Master or slave I2C mode support
— On-chip digital filtering rejects spikes on the bus
— System initialization data optionally loaded from I2C-1 EPROM by boot sequencer embedded
hardware
DMA controller
— Four independent virtual channels
— Concurrent execution across multiple channels with programmable bandwidth control
— Handshaking (external control) signals for all channels: DMA_DREQ[0:3],
DMA_DACK[0:3], DMA_DDONE[0:3]
— All channels accessible to local core and remote PCI masters
