    — Supports auto refreshing
    — On-the-fly power management using CKE signal
    — Registered DIMM support
    — Fast memory access via JTAG port
    — 2.5-V SSTL2 compatible I/O
    RapidIO interface unit
    — 8-bit RapidIO I/O and messaging protocols
    — Source-synchronous double data rate (DDR) interfaces
    — Supports small type systems (small domain, 8-bit device ID)
    — Supports four priority levels (ordering within a level)
    — Reordering across priority levels
    — Maximum data payload of 256 bytes per packet
    — Packet pacing support at the physical layer
    — CRC protection for packets
    — Supports atomic operations increment, decrement, set, and clear
    — LVDS signaling
    RapidIO–compliant message unit
    — One inbound data message structure (inbox)
    — One outbound data message structure (outbox)
    — Supports chaining and direct modes in the outbox
    — Support of up to 16 packets per message
    — Support of up to 256 bytes per packet and up to 4 Kbytes of data per message
    — Supports one inbound doorbell message structure
    Programmable interrupt controller (PIC)
    — Programming model is compliant with the OpenPIC architecture
    — Supports 16 programmable interrupt and processor task priority levels
    — Supports 12 discrete external interrupts
    — Supports 4 message interrupts with 32-bit messages
    — Supports connection of an external interrupt controller such as the 8259 programmable
    interrupt controller
    — Four global high resolution timers/counters that can generate interrupts
    — Supports 22 other internal interrupt sources
    — Supports fully nested interrupt delivery
    — Interrupts can be routed to external pin for external processing
