Introduction
MP3 decode requires less than 20 MHz CPU bandwidth and runs from on-chip SRAM.
The MCF5251 is a general purpose system controller with over 125 Dhrystone 2.1 MIPS @ 140 MHz
performance. The integrated peripherals and EMAC allow the MCF5251 to replace both the
microcontroller and the DSP in certain applications. Most peripheral pins can also be remapped as General
Purpose I/O pins.

Functional Description and Application Information
2.1
MCF5251 ColdFire® Core
The ColdFire processor Version 2 (CF2) core consists of two independent, decoupled pipeline structures
to maximize performance while minimizing core size. The instruction fetch pipeline (IFP) is a two-stage
pipeline for prefetching instructions. The prefetched instruction stream is then gated into the two-stage
operand execution pipeline (OEP), which decodes the instruction, fetches the required operands, and then
executes the required function.

The timer module includes two general-purpose timers, each of which
contains a free-running 16-bit timer.
IDE
Integrated Drive
Electronics
Connectivity
peripheral
The IDE hardware consists of bus buffers for address and data and are
intended to reduce the load on the bus and prevent SDRAM and Flash
accesses from propagating to the IDE bus.
INC

The instruction cache improves system performance by providing cached
instructions to the execution unit in a single clock cycle.
I2C
Inter IC
Communication
Module
Connectivity
peripheral
The two-wire I2C bus interfaces, compliant with the Philips I2C bus
standard, are bidirectional serial buses that exchange data between
devices.
SRAM
Internal 128-KB
SRAM
Internal
memory
The 128-Kbyte on-chip SRAM is split over two banks, SRAM0 (64K) and
SRAM1 (64K). It provides single clock-cycle access for the ColdFire core.
LIN
Internal Voltage
Regulator
Linear
regulator
An internal 1.2 V regulator is used to supply the CPU and PLL sections of
the MCF5251, reducing the number of external components required and
allowing operation from a single supply rail, typically 3.3 volts.
JTAG
Joint Test Action
Group
Test and
debug
To help with system diagnostics and manufacturing testing, the MCF5251
includes dedicated user-accessible test logic that complies with the IEEE
1149.1A standard for boundary scan testability, often referred to as Joint
Test Action Group, or JTAG.
QSPI
Queued Serial
Peripheral Interface
Connectivity
Interface
The QSPI module provides a serial peripheral interface with queued
transfer capability.
RTC
Real-Time Clock
Timer
Peripheral
The RTC is a clock that keeps track of the current time even if the clock is
turned off.
BDM
Background Debug
Interface
Test and
debug
A background-debug mode (BDM) interface provides system debug.
SDRAMC
Synchronous DRAM
Memory Controller
Peripheral
Interface
The SDRAM controller provides a glueless interface for one bank of
SDRAM, and can address up to 32MB. The controller supports a 16-bit
data bus. The controller operates in page mode, non-page mode, and
burst-page mode and supports SDRAMs.
SIM
System Integration
Module
System
Integration
The SIM provides overall control of the internal and external buses and
serves as the interface between the ColdFire core and the internal
peripherals or external devices. The SIM is responsible for the two
interrupt controllers (setting priorities and levels). And it also configures
the GPIO ports.
PLL
System Oscillator and System
Phase Lock Loop
Clocking
The oscillator operates from an external crystal connected across CRIN
and CROUT. The circuit can also operate from an external clock
connected to CRIN. The on-chip programmable PLL, which generates the
processor clock, allows the use of almost any low frequency external clock
(5–35 MHz).

NOTE
A pmos regulator is used as a current source in this linear regulator, so a
10 µF capacitor (ESR 0... 5 Ohm) is needed on the output pin (LINOUT) to
integrate the current. Typically, this requires the use of a tantalum type
capacitor.

SDRAM Bus Timing
The SDRAM bus is a synchronous bus. Propagation delays, set-up times and hold times with respect to
the SDRAM clock BCLK are shown in Figure 3 and the parameters provided in Table 11. When BCLK
clock is not active, SDRAM interface is not valid and the external bus cannot be used.

SPDIF Timing
The Sony/Philips Digital Interface (SPDIF) timing parameters are provided in Table 12. SPDIF timing is
totally asynchronous, therefore there is no need for relationship with the clock. Table 12 shows the
differences between high-low and low-high propagation delay which is called the skew.

Note that output data may go invalid before rising edge of the clock. To clock data in reliably, you need to sample data, for
example, 2 ns before rising edge of clock.
