MCF548x Integrated Microprocessor Hardware Specifications

PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
MCF548x Family Overview
To maximize throughput, the MCF548x family incorporates three independent external bus interfaces:
1. The general-purpose local bus (FlexBus) is used for system boot memories and simple peripherals
and has up to six chip selects.
2. Program code and data can be stored in SDRAM connected to a dedicated 32-bit double data rate
(DDR) bus that can run at up to one half of the CPU core frequency. The glueless DDR SDRAM
controller handles all address multiplexing, input and output strobe timing, and memory bus clock
generation.
3. A 32-bit PCI bus compliant with the version 2.2 specification and running at a typical frequency of
33 MHz or 66 MHz supports peripherals that require high bandwidth, the ability to arbitrate for
bus mastership, and access to internal MCF548x memory resources.
The MCF548x family provides substantial communications functionality by integrating the following
connectivity peripherals:
Up to two 10/100 Mbps fast Ethernet controllers (FECs)
An optional USB 2.0 device (slave) module with seven endpoints and an integrated transceiver
Up to four UART/USART/IRDA/modem programmable serial controllers (PSCs)
A DMA serial peripheral interface (DSPI)
An inter-integrated circuit (I2C) bus controller
Two controller area network 2.0B (FlexCAN) interfaces with 16 message buffers each
Additionally, the MCF548x provides hardware support for a range of Internet security standards with an
optional bus-mastering cryptography accelerator. This module incorporates units to speed DES/3DES and
AES block ciphers, the RC4 stream cipher, bulk data hashing (MD5/SHA-1/SHA-256/HMAC), and random
number generation. Hardware acceleration of these functions is critical to avoiding the throughput
bottlenecks associated with software-only implementations of SSH, SSL/TLS, IPsec, SRTP, WEP, and other
security standards. The incorporation of cryptography acceleration makes the MCF548x family a
compelling solution for a wide range of office automation, industrial control, and SOHO networking
devices that must have the ability to securely transmit critical equipment control information across
typically insecure Ethernet data networks.
Additional features of MCF548x products include a watchdog timer, two 32-bit slice timers for RTOS
scheduling and alarm functionality, up to four 32-bit general-purpose timers with capture, compare, and
pulse width modulation capability, a multisource vectored interrupt controller, a phase-locked loop (PLL)
to generate the system clock, 32 Kbytes of SRAM for high-speed local data storage, and multiple
general-purpose I/O ports. To manage current consumption, MCF548x products provide chip-wide internal
clock gating control on a per module basis under software control.
With on-chip support for multiple common communications interfaces, MCF548x products require only the
addition of memories and certain physical layer transceivers to be cost-effective system solutions for many
applications, such as industrial routers, high-end POS terminals, building automation systems, and process
control equipment.
MCF548x products require four supply voltages: 1.5V for the high-performance, low power, internal core
logic, 2.5V for the DDR SDRAM bus interface, 1.25V for the DDR SDRAM VREF, and 3.3V for all other
I/O functionality, including the PCI and FlexBus interfaces.
