All specifications other than those relating to security apply to the MPC8568 and MPC8567 exactly as described in this document. 1.2 1.2.1 MPC8568E Architecture Overview e500 Core and Memory Unit The MPC8568E contains a high-performance, 32-bit, Book E–enhanced e500v2 Power Architecture core. In addition to 36-bit physical addressing, this version of the e500 core includes the following: • Double-precision floating-point APU—Provides an instruction set for double-precision (64-bit) floating-point instructions that use the 64-bit GPRs • Embedded vector and scalar single-precision floating-point APUs—Provide an instruction set for single-precision (32-bit) floating-point instructions The MPC8568E also contains 512 Kbytes of L2 cache/SRAM, as follows: • Eight-way set-associative cache organization with 32-byte cache lines • Flexible configuration (can be configured as part cache, part SRAM) • External masters can force data to be allocated into the cache through programmed memory ranges or special transaction types (stashing). • SRAM features include the following: — I/O devices access SRAM regions by marking transactions as snoopable (global). — Regions can reside at any aligned location in the memory map. MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 Freescale Semiconductor 3 MPC8568E Overview — Byte-accessible ECC uses read-modify-write transaction accesses for smaller-than-cache-line accesses. 1.2.2 e500 Coherency Module (ECM) and Address Map The e500 coherency module (ECM) provides a mechanism for I/O-initiated transactions to snoop the bus between the e500 core and the integrated L2 cache in order to maintain coherency across local cacheable memory. It also provides a flexible switch-type structure for core- and I/O-initiated transactions to be routed or dispatched to target modules on the device. The MPC8568E supports a flexible 36-bit physical address map. Conceptually, the address map consists of local space and external address space. The local address map is supported by eight local access windows that define mapping within the local 36-bit (64-Gbyte) address space. The MPC8568E can be made part of a larger system address space through the mapping of translation windows. This functionality is included in the address translation and mapping units (ATMUs). Both inbound and outbound translation windows are provided. The ATMUs allows the MPC8568E to be part of larger address maps such as the PCI or PCI Express 64-bit address environment and the RapidIO environment. 1.2.3 • QUICC Engine Integrated 8-port L2 Ethernet switch — 8 connection ports of 10/100 Mbps MII/RMII & one CPU internal port — Each port supports four priority levels — Priority levels used with VLAN tags or IP TOS field to implement QoS — QoS types of traffic, such as voice, video, and data Includes support for the following protocols: — ATM SAR up to 622 Mbps (OC-12) full duplex, with ATM traffic shaping (ATF TM4.1) for up to 64K ATM connections — ATM AAL1 structured and unstructured Circuit Emulation Service (CES 2.0) — IMA and ATM Transmission convergence sub-layer — ATM OAM handling features compatible with ITU-T I.610 — PPP, Multi-Link (ML-PPP), Multi-Class (MC-PPP) and PPP mux in accordance with the following RFCs: 1661, 1662, 1990, 2686 and 3153 — IP termination support for IPv4 and IPv6 packets including TOS, TTL and header checksum processing — ATM (AAL2/AAL5) to Ethernet (IP) interworking — Extensive support for ATM statistics and Ethernet RMON/MIB statistics. — 256 channels of HDLC/Transparent or 128 channels of SS#7 Includes support for the following serial interfaces: — Two UL2/POS-PHY interfaces with 124 Multi-PHY addresses on UTOPIA interface each or 31 Multi-PHY addresses on the POS interface each.

Although it is not a protocol processor, the SEC is designed to perform multi-algorithmic operations (for example, 3DES-HMAC-SHA-1) in a single pass of the data. The version of the SEC used in the MPC8568E is specifically capable of performing single-pass security cryptographic processing for SSL 3.0, SSL 3.1/TLS 1.0, IPSec, SRTP, and 802.11i. • Optimized to process all the algorithms associated with IPSec, IKE, WTLS/WAP, SSL/TLS, and 3GPP • Compatible with code written for the Freescale MPC8541E and MPC8555E devices • XOR engine for parity checking in RAID storage applications. • Four crypto-channels, each supporting multi-command descriptor chains • Cryptographic execution units: — PKEU—public key execution unit — DEU—Data Encryption Standard execution unit — AESU—Advanced Encryption Standard unit — AFEU—ARC four execution unit — MDEU—message digest execution unit — KEU—Kasumi execution unit — RNG—Random number generator 1.2.5 Enhanced Three-Speed Ethernet Controllers The MPC8568E has two on-chip enhanced three-speed Ethernet controllers (eTSECs). The eTSECs incorporate a media access control (MAC) sublayer that supports 10- and 100-Mbps and 1-Gbps Ethernet/802.3 networks with MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces. The eTSECs include 2-Kbyte receive and 10-Kbyte transmit FIFOs and DMA functions. The MPC8568E eTSECs support programmable CRC generation and checking, RMON statistics, and jumbo frames of up to 9.6 Kbytes. Frame headers and buffer descriptors can be forced into the L2 cache to speed classification or other frame processing. They are IEEE Std 802.3™, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z, IEEE 802.3ac, IEEE 802.3ab-compatible. The buffer descriptors are based on the MPC8260 and MPC860T 10/100 Ethernet programming models. Each eTSEC can emulate a PowerQUICC III TSEC, allowing existing driver software to be re-used with minimal change. Some of the key features of these controllers include: • Flexible configuration for multiple PHY interface configurations. Table 1 lists available configurations.

The memory interface controls main memory accesses and provides for a maximum of 16 Gbytes of main memory. The MPC8568E supports a variety of SDRAM configurations. SDRAM banks can be built using DIMMs or directly-attached memory devices. Sixteen multiplexed address signals provide for device densities of 64 Mbits, 128 Mbits, 256 Mbits, 512 Mbits, 1 Gbits, 2 Gbits and 4 Gbits. Four chip select signals support MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 6 Freescale Semiconductor MPC8568E Overview up to four banks of memory. The MPC8568E supports bank sizes from 64 Mbytes to 4 Gbytes. Nine column address strobes (MDM[0:8]) are used to provide byte selection for memory bank writes. The MPC8568E can be configured to retain the currently active SDRAM page for pipelined burst accesses. Page mode support of up to 16 simultaneously open pages (32 for DDR2) can dramatically reduce access latencies for page hits. Depending on the memory system design and timing parameters, using page mode can save 3 to 4 clock cycles from subsequent burst accesses that hit in an active page. Using ECC, the MPC8568E detects and corrects all single-bit errors and detects all double-bit errors and all errors within a nibble. The MPC8568E can invoke a level of system power management by asserting the MCKE SDRAM signal on-the-fly to put the memory into a low-power sleep mode. 1.2.7 Table Lookup Unit (TLU) The table lookup unit (TLU) provides access to application-defined routing topology and control tables in external memory. It accesses an external memory array attached to the local bus controller (LBC). Communication between the CPU and the TLU occurs via messages passed through the TLU’s memory-mapped configuration and status registers. The TLU provides resources for efficient generation of table entry addresses in memory, hash generation of addresses, and binary table searching algorithms for both exact-match and longest-prefix-match strategies.It supports the following TLU complex table types: • Hash-Trie-Key table for hash-based exact-match algorithms • Chained-Hash table for partially indexed and hashed exact-match algorithms • Longest-prefix-match algorithm • Flat-Data table for retrieving search results and simple indexed algorithms 1.2.8 PCI Controller The MPC8568E supports one 32-bit PCI controller, which supports speeds of up to 66 MHz. Other features include: • Compatible with the PCI Local Bus Specification, Revision 2.2, supporting 32- and 64-bit addressing • Can function as host or agent bridge interface • As a master, supports read and write operations to PCI memory space, PCI I/O space, and PCI configuration space • Can generate PCI special-cycle and interrupt-acknowledge commands. As a target, it supports read and write operations to system memory as well as configuration accesses. • Supports PCI-to-memory and memory-to-PCI streaming, memory prefetching of PCI read accesses, and posting of processor-to-PCI and PCI-to-memory writes • PCI 3.3-V compatible with selectable hardware-enforced coherency MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 Freescale Semiconductor 7 MPC8568E Overview 1.2.9 High Speed I/O Interfaces The MPC8568E supports two high-speed I/O interface standards: serial RapidIO and PCI Express. It can be configured as x1/x4 SRIO and 1x/2x/4x PCI Express simultaneously with the following limitation: • Both SRIO and PCI-Express are limited to use the same clock and are limited to 2.5G. • Spread spectrum clocking can not be used because SRIO doesn't support this (PCI-Express does support it). If x8 PCI Express is needed, then SRIO is not available due to the pin multiplex limitation. 1.2.10 Serial RapidIO The serial RapidIO interface is based on the RapidIO Interconnect Specification, Revision 1.2. RapidIO is a high-performance, point-to-point, low-pin-count, packet-switched system-level interconnect that can be used in a variety of applications as an open standard. The RapidIO architecture has a rich variety of features including high data bandwidth, low-latency capability, and support for high-performance I/O devices, as well as support for message-passing and software-managed programming models. Key features of the serial RapidIO interface unit include: • Support for RapidIO Interconnect Specification, Revision 1.2 (all transaction flows and priorities) • Both 1x and 4x LP-serial link interfaces, with transmission rates of 1.25, 2.5, and 3.125 Gbaud (data rates of 1.0, 2.0, and 2.5 Gbps) per lane • Auto detection of 1x or 4x mode operation during port initialization • 34-bit addressing and up to 256-byte data payload • Receiver-controlled flow control • Support for RapidIO error injection The RapidIO messaging unit supports two inbox/outbox mailboxes (queues) for data and one doorbell message structure. Both chaining and direct modes are provided for the outbox, and messages can hold up to 16 packets of 256 bytes, or a total of 4 Kbytes. 1.2.11 PCI Express Interface The MPC8568E supports a PCI Express interface compatible with the PCI Express Base Specification Revision 1.0a. It is configurable at boot time to act as either root complex or endpoint.The physical layer of the PCI Express interface operates at a 2.5-Gbaud data rate per lane. Other features of the PCI Express interface include: • x8, x4, x2, and x1 link widths supported • Selectable operation as root complex or endpoint • Both 32- and 64-bit addressing and 256-byte maximum payload size • Full 64-bit decode with 32-bit wide windows MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 8 Freescale Semiconductor MPC8568E Overview 1.2.12 Programmable Interrupt Controller (PIC) The MPC8568E PIC implements the logic and programming structures of the OpenPIC architecture, providing for external interrupts (with fully nested interrupt delivery), message interrupts, internal-logic driven interrupts, and global high-resolution timers. Up to 16 programmable interrupt priority levels are supported. The PIC can be bypassed to allow use of an external interrupt controller. 1.2.13 DMA Controller, I2C, DUART, and Local Bus Controller The MPC8568E provides an integrated four-channel DMA controller, which can transfer data between any of its I/O or memory ports or between two devices or locations on the same port. The DMA controller also: • Allows chaining (both extended and direct) through local memory-mapped chain descriptors. • Scattering, gathering, and misaligned transfers are supported. In addition, stride transfers and complex transaction chaining are supported. • Local attributes such as snoop and L2 write stashing can be specified. There are two I2C controllers. These synchronous, multimaster buses can be connected to additional devices for expansion and system development. The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550 programming models. 16-byte FIFOs are supported for both the transmitter and the receiver. The MPC8568E local bus controller (LBC) port allows connections with a wide variety of external memories, DSPs, and ASICs. Three separate state machines share the same external pins and can be programmed separately to access different types of devices. The general-purpose chip select machine (GPCM) controls accesses to asynchronous devices using a simple handshake protocol. The user programmable machine (UPM) can be programmed to interface to synchronous devices or custom ASIC interfaces. The SDRAM controller provides access to standard SDRAM. Each chip select can be configured so that the associated chip interface can be controlled by the GPCM, UPM, or SDRAM controller. All may exist in the same system. The local bus controller supports the following features: • Multiplexed 32-bit address and data bus operating at up to 133 MHz • Eight chip selects support eight external slaves • Up to eight-beat burst transfers • 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller • Three protocol engines available on a per-chip-select basis • Parity support • Default boot ROM chip select with configurable bus width (8, 16, or 32 bits) • Supports zero-bus-turnaround (ZBT) RAM 1.2.14 Power Management In addition to low-voltage operation and dynamic power management, which automatically minimizes power consumption of blocks when they are idle, four power consumption modes are supported: full on, doze, nap, and sleep.

Overshoot/Undershoot Voltage for BVDD/GVDD/LVDD/TVDD/OVDD MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 12 Freescale Semiconductor Electrical Characteristics The core voltage must always be provided at nominal 1.1V. (See Table 3 for actual recommended core voltage). Voltage to the processor interface I/Os are provided through separate sets of supply pins and must be provided at the voltages shown in Table 3. The input voltage threshold scales with respect to the associated I/O supply voltage. OVDD and LVDD based receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR SDRAM interface uses a single-ended differential receiver referenced the externally supplied MVREF signal (nominally set to GVDD/2) as is appropriate for the SSTL2 electrical signaling standard. 2.1.3 Output Driver Characteristics Table 4 provides information on the characteristics of the output driver strengths. The values are preliminary estimates. Table 4.

The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR. 2. The drive strength of the PCI interface is determined by the setting of the PCI_GNT[1] signal at reset. 2.2 Power Sequencing The MPC8568E requires its power rails to be applied in specific sequence in order to ensure proper device operation. These requirements are as follows for power up: 1. VDD, AVDD_n, BVDD, SCOREVDD, LVDD, TVDD, XVDD, OVDD 2. GVDD All supplies must be at their stable values within 50 ms. MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 Freescale Semiconductor 13 Power Characteristics NOTE Items on the same line have no ordering requirement with respect to one another. Items on separate lines must be ordered sequentially such that voltage rails on a previous step must reach 90% of their value before the voltage rails on the current step reach 10% of theirs. In order to guarantee MCKE low during power-up, the above sequencing for GVDD is required. If there is no concern about any of the DDR signals being in an indeterminate state during power-up, then the sequencing for GVDD is not required. 3 Power Characteristics The power dissipation of VDD for various core complex bus (CCB) versus the core and QE frequency for MPC8568E is shown in Table 5. Note that this is based on the design estimate only. More accurate power number will be available after we have done the measurement on the silicon. Table 5.
