 Intergrated Processor Hardware Specifications





This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications for the .29 μm (HiP3) devices of the PowerQUICC II family of communications processors: the MPC8260 and the MPC8255. Throughout this document, the MPC8260 and the MPC8255 are collectively referred to as the MPC8260.





• Dual-issue integer core

— A core version of the EC603e microprocessor

— System core microprocessor supporting frequencies of 133–200 MHz (150–200 MHz for the MPC8255)

— Separate 16-Kbyte data and instruction caches:

– Four-way set associative

– Physically addressed

– LRU replacement algorithm

— PowerPC architecture-compliant memory management unit (MMU)

— Common on-chip processor (COP) test interface

200 MHz)

— Supports bus snooping for data cache coherency

— Floating-point unit (FPU)

• Separate power supply for internal logic and for I/O

• Separate PLLs for G2 core and for the CPM

— G2 core and CPM can run at different frequencies for power/performance optimization

— Internal core/bus clock multiplier that provides 1.5:1, 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 5:1, 6:1 ratios

— Internal CPM/bus clock multiplier that provides 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 5:1, 6:1 ratios

• 64-bit data and 32-bit address 60x bus

— Bus supports multiple master designs

— Supports single- and four-beat burst transfers

— 64-, 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller

— Supports data parity or ECC and address parity

• 32-bit data and 18-bit address local bus

— Single-master bus, supports external slaves

— Eight-beat burst transfers

— 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller

• System interface unit (SIU)

— Clock synthesizer

— Reset controller

— Real-time clock (RTC) register

— Periodic interrupt timer

— Hardware bus monitor and software watchdog timer

— IEEE Std 1149.1™ JTAG test access port

— Byte write enables and selectable parity generation

— 32-bit address decodes with programmable bank size

— Three user programmable machines, general-purpose chip-select machine, and page-mode pipeline SDRAM machine

— Byte selects for 64 bus width (60x) and byte selects for 32 bus width (local)

— Dedicated interface logic for SDRAM

• CPU core can be disabled and the device can be used in slave mode to an external core

• Communications processor module (CPM)

— Embedded 32-bit communications processor (CP) uses a RISC architecture for flexible support for communications protocols

— Interfaces to G2 core through on-chip 24-Kbyte dual-port RAM and DMA controller

— Serial DMA channels for receive and transmit on all serial channels

— Parallel I/O registers with open-drain and interrupt capability

— Virtual DMA functionality executing memory-to-memory and memory-to-I/O transfers

— Three fast communications controllers (two on the MPC8255) supporting the following protocols:

– 10/100-Mbit Ethernet/IEEE Std 802.3™ CDMA/CS interface through media independent interface (MII)

– ATM—Full-duplex SAR protocols at 155 Mbps, through UTOPIA interface, AAL5, AAL1,

AAL0 protocols, TM 4.0 CBR, VBR, UBR, ABR traffic types, up to 16 K external connections

– Transparent

– HDLC—Up to T3 rates (clear channel)

— Two multichannel controllers (MCCs) (only MCC2 on the MPC8255)

– Each MCC handles 128 serial, full-duplex, 64-Kbps data channels. Each MCC can be split into four subgroups of 32 channels each.

– Almost any combination of subgroups can be multiplexed to single or multiple TDM interfaces up to four TDM interfaces per MCC

— Four serial communications controllers (SCCs) identical to those on the MPC860, supporting the digital portions of the following protocols:

– Ethernet/IEEE 802.3 CDMA/CS

– HDLC/SDLC and HDLC bus

– Universal asynchronous receiver transmitter (UART)

– Synchronous UART

– Binary synchronous (BISYNC) communications

– Transparent

— Two serial management controllers (SMCs), identical to those of the MPC860

– Provide management for BRI devices as general circuit interface (GCI) controllers in time- division-multiplexed (TDM) channels

– Transparent

– UART (low-speed operation)

— One serial peripheral interface identical to the MPC860 SPI

— One inter-integrated circuit (I2C) controller (identical to the MPC860 I2C controller)

– Microwire compatible

– Multiple-master, single-master, and slave modes

— Up to eight TDM interfaces (4 on the MPC8255)

– Supports two groups of four TDM channels for a total of eight TDMs

– 2,048 bytes of SI RAM

– Bit or byte resolution

– Independent transmit and receive routing, frame synchronization
