MCF548x Integrated Microprocessor Hardware Specifications
MOTOROLA
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
MCF548x Family Features
Cache line reads that can use critical word first. These reads can start in the center of a burst and
will wrap to the beginning. This allows the processor quicker access to a needed instruction.
All on-chip bus masters have access to DRAM. This includes PCI, the ColdFire V4e core, the cryptography
accelerator, and the DMA controller.
1.4.8
Peripheral Component Interconnect (PCI)
The PCI controller is a PCI V2.2-compliant bus controller and arbiter. The PCI bus is capable of 66-MHz
operation with a 32-bit address/data bus and support for five external masters.
The PCI module includes an inbound FIFO to increase performance when using an external bus master. The
bus can address all 4 Gbytes of PCI-addressable space.
The PCI bus is also multiplexed with the flexible local bus (FlexBus) address lines. If 32-bit non-muxed
local address and data is required it can be obtained at the expense of utilizing the PCI bus.
When implemented, the PCI controller acts as the central resource, bus arbiter, and configuring master on
the PCI bus.
1.4.9
Flexible Local Bus (FlexBus)
The FlexBus module is intended to provide the user with basic functionality required to interface to
peripheral devices. The FlexBus interface is a multiplexed or non-multiplexed bus, with an operating
frequency from 33–66 MHz. The Flexbus is targeted to support external Flash memories, boot ROMs,
gate-array logic, or other simple target interfaces. Up to six chip selects are supported by the FlexBus.
Possible combinations of address and data bits are:
Non-multiplexed 32-bit address and 32-bit data (32-bit address muxed over
PCI bus–PCI not usable)
Multiplexed 32-bit address and 32-bit data (PCI usable)
Multiplexed 32-bit address and 16-bit data
Multiplexed 32-bit address and 8-bit data
The non-multiplexed 32-bit address and 32-bit data mode is determined at chip reset. For all other modes,
the full 32-bit address is driven during the address phase. The number of bytes used for data are determined
on a chip select by chip select basis.
1.4.10 Security Encryption Controller (SEC)
As consumers and businesses continue to embrace the Internet, the need for secure point-to-point
communications across what is an entirely insecure network has been met by the development of a range of
standard protocols. Computer cryptography fundamentally involves calculations with very large numbers.
Personal computers have sufficient processing power to implement these algorithms entirely in software.
When placed upon the embedded devices typically used for routing and remote access functions, this same
computational burden can potentially decrease the throughput of a 100 Mbps Ethernet interface down to 10
Mbps.
Hardware acceleration of common cryptography algorithms is the solution to the computational bandwidth
requirements of Internet security standards. Discrete solutions currently address this problem, but the next
