PowerQUICC III
Integrated Processor
Hardware Specifications
Due to feature similarities, this document covers both the
MPC8568E and MPC8567E features. For simplicity,
MPC8568 may only be mentioned throughout the document.
The MPC8567E feature differences are as follows:
• The MPC8567E PCI-Express supports x1/x2/x4, but
does not have x8 support.
• Does not have eTSEC1, eTSEC2, or TLU
Note that both the MPC8568E and MPC8567E have their
own pin assignment tables.

NOTE
The MPC8568E and MPC8567E are also available without a security

specifications other than those relating to security apply to the MPC8568
and MPC8567 exactly as described in this document.

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 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.

MPC8568E Overview
— Three 1-Gbps Ethernet interfaces using three GMII, two RGMII/TBI/RTBI
— Up to eight 10/100-Mbps Ethernet interfaces using MII or RMII
— Up to eight T1/E1/J1/E3 or DS-3 serial interfaces
1.2.4
Integrated Security Engine (SEC)
The SEC is a modular and scalable security core optimized to process all the algorithms associated with
IPSec, IKE, WTLS/WAP, SSL/TLS, and 3GPP. 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.
