•

DDR SDRAM memory controller

— Programmable timing supporting DDR2 SDRAM

— Integrated SDRAM clock generation

— 16-bit data interface, up to 266-MHz data rate

— 14 address lines

— The following SDRAM configurations are supported:

– Up to two physical banks (chip selects), 256-Mbyte per chip select for 16 bit data interface.

– 64-Mbit to 2-Gbit devices with x8/x16 data ports (no direct x4 support)

– One 16-bit device or two 8-bit devices on a 16-bit bus,

— Support for up to 16 simultaneous open pages for DDR2

— One clock pair to support up to 4 DRAM devices

— Supports auto refresh

— On-the-fly power management using CKE

•

Enhanced local bus controller (eLBC)

— Multiplexed 26-bit address and 8-/16-bit data operating at up to 66 MHz

— Eight chip selects supporting eight external slaves

– Four chip selects dedicated

– Four chip selects offered as multiplexed option

— Supports boot from parallel NOR Flash and parallel NAND Flash

— Supports programmable clock ratio dividers

— Up to eight-beat burst transfers

— 16- and 8-bit ports, separate LWE for each 8 bit

— Three protocol engines available on a per chip select basis:

– General-purpose chip select machine (GPCM)

– Three user programmable machines (UPMs)

– NAND Flash control machine (FCM)

— Variable memory block sizes for FCM, GPCM, and UPM mode

— Default boot ROM chip select with configurable bus width (8 or 16)

— Provides two Write Enable signals to allow single byte write access to external 16-bit eLBC

slave devices

•

Integrated programmable interrupt controller (IPIC)

— Functional and programming compatibility with the MPC8260 interrupt controller

— Support for external and internal discrete interrupt sources

— Programmable highest priority request
