MPC859P/859T/859DSLBlock Diagram 1.2 Embedded MPC8xx Core The MPC859P/859T/859DSL Family integrates an embedded MPC8xx core with high-performance, low-power peripherals to extend the Motorola data communications family of embedded processors farther into high-end communications and networking products. The core is compliant with the UISA (user instruction set architecture) portion of the PowerPC architecture. It has an integer unit (IU) and a load/store unit (LSU) that execute all integer and load/store operations in hardware. The core supports integer operations on a 32-bit internal data path and 32-bit arithmetic hardware. The core interface to the internal and external buses is 32 bits. 6 MPC859P/859T/859DSL PowerQUICC™ Family Technical Summary For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. System Interface Unit (SIU) The IU uses 32, 32-bit GPRs for source and target operands. Typically, it can execute one integer instruction each clock cycle. Each element in the integer block is clocked only when valid data is in the data queue and is ready for operation. This holds power consumption of the device to the absolute minimum. The core is integrated with MMUs as well as instruction and data caches. Each MMU provides a 32-entry, fully associative instruction and data TLB, with multiple page sizes of 4, 16, 512, and 256 Kbytes and 8 Mbytes. It supports 16 virtual address spaces with 8 protection groups. Three special scratch registers support software table search and update operations. Freescale Semiconductor, Inc... The instruction cache is four-way, set associative with physical addressing. It allows single-cycle access on hits with no added latency for misses. It has four words per block, supporting a four-beat burst line fill using an LRU (least recently used) replacement algorithm. The cache can be locked on a per cache block basis for application-critical routines. The data cache is two-way, set associative with physical addressing. It allows single-cycle accesses on hits with one added clock latency for misses. It has four words per cache block, supporting burst line fill using LRU replacement. The cache can be locked on a per block basis for application critical routines. The data cache can be programmed through the MMU to support copy-back or write-through. Cache-inhibit mode can be programmed per MMU page. The debug interface provides debug capabilities without degrading operation speed. This interface supports six watchpoint pins that are used to detect software events. Four of its eight internal comparators operate on the effective address on the address bus, two operate on the effective address on the data address bus, and two operate on the data bus. The core can make =, ≠, <, and > comparisons to generate watchpoints. Each watchpoint can then generate a break point that can be configured to trigger in a programmable number of events. 1.3 System Interface Unit (SIU) The SIU on the MPC859P/859T/859DSL Family integrates general-purpose features useful in almost any 32-bit processor system. Dynamic bus sizing allows 8-, 16-, and 32-bit peripherals and memory to exist in the 32-bit system bus mode. The SIU also provides power management functions, reset control, decrementer, and timebase. The memory controller supports up to eight memory banks with glueless interfaces to DRAM, SRAM, SSRAM, EPROM, Flash EPROM, SDRAM, EDO, and other peripherals with 2-clock-cycle access to external SRAM and bursting support. It provides variable block sizes from 32 Kbytes to 256 Mbytes. The memory controller provides 0–30 wait states for each memory bank and can use address type matching to qualify each memory bank access. It provides four byte-enable signals, an output-enable signal. and a boot chip select available at reset. The DRAM interface supports port sizes of 8, 16, and 32 bits. Memory banks can be defined in depths of 256 or 512 Kbytes or 1, 2, 4, 8, 16, 32, or 64 Mbytes for all port sizes. The memory depth can be 64 and 128 Kbytes for 8-bit memory or 128 and 256 Mbytes for 32-bit memory. The DRAM controller supports page-mode access for successive transfers within bursts. The MPC859P/859T/859DSL supports a glueless interface to one bank of DRAM while external buffers are required for additional memory banks. The refresh unit provides CAS before RAS, a programmable refresh timer, refresh active during external reset, disable refresh mode, and stacking up to 7 refresh cycles. The DRAM interface uses a programmable state machine to support almost any memory interface.

PCMCIA Controller 1.4 PCMCIA Controller The PCMCIA interface is a master (socket) controller and is compliant with release 2.1. The interface supports up to two independent PCMCIA sockets requiring only external transceivers/buffers. The interface provides eight memory or I/O windows where each window can be allocated to a particular socket. If only one PCMCIA port is used, the unused port may be used as general-purpose input with interrupt capability. On the MPC859DSL, PCMCIA support is provided on Port B only. Freescale Semiconductor, Inc... 1.5 Power Management The MPC859P/859T/859DSL Family supports two power management features including Normal High and Normal Low Power Modes. Full on mode leaves the MPC8 processor fully powered with all internal units operating at the full processor speed. A gear mode is determined by a clock divider, allowing the operating system to reduce the processor’s operational frequency and operate in Normal Low Mode. 1.6 Communications Processor Module (CPM) The MPC859P/859T/859DSL Family is the next generation MPC8xx family of devices. Like its predecessor it implements a dual-processor architecture, which provides both a high-performance, general-purpose processor for application programming use as well as a special-purpose communication processor (CPM) uniquely designed for communications applications. The CPM contains features that, like its predecessor, allow the MPC859P/859T/859DSL Family to excel in communications and networking products. These features are grouped as follows: • • • Communications processor (CP) Ten independent DMA (SDMA) controllers on the MPC859T; eight independent DMA (SDMA) controllers on the MPC859DSL Four general-purpose timers The CP provides the communication features of the MPC859P/859T/859DSL. Included are a RISC processor, one serial communication controller (SCC1), two serial management controllers (SMCs), a serial peripheral interface (SPI), an I2C interface, 8 Kbytes of dual-port RAM, an interrupt controller, a time-slot assigner, three parallel ports, a parallel interface port, four independent baud rate generators, and ten serial DMA channels to support the SCC, SMCs, SPI, and I2C. The SDMAs provide two channels of general-purpose DMA capability for each communications channel. They offer high-speed transfers, 32-bit data movement, buffer chaining, and independent request and acknowledge logic. The four general-purpose timers on the CPM are identical to the timers found on all of the MPC8xx devices, and supporting the internal cascading of two timers to form a 32-bit timer. 1.7 ATM Capabilities The MPC859P/859T/859DSL Family can be used as an adaptable ATM controller suited for a variety of applications, including the following: • • • 8 DSLAM Line Cards Access Concentrators LAN/WAN Switches MPC859P/859T/859DSL PowerQUICC™ Family Technical Summary For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.
