1.2.2 V2 Core Overview
The version 2 ColdFire processor core is comprised of two separate pipelines decoupled by an instruction buffer. The two-stage
instruction fetch pipeline (IFP) is responsible for instruction-address generation and instruction fetch. The instruction buffer is
a first-in-first-out (FIFO) buffer that holds prefetched instructions awaiting execution in the operand execution pipeline (OEP).
The OEP includes two pipeline stages. The first stage decodes instructions and selects operands (DSOC); the second stage
(AGEX) performs instruction execution and calculates operand effective addresses, if needed.
The V2 core implements the ColdFire instruction set architecture revision A+ with support for a separate user stack pointer
register and four new instructions to assist in bit processing. Additionally, the core includes the multiply-accumulate (MAC)
unit for improved signal processing capabilities. The MAC implements a three-stage arithmetic pipeline, optimized for 16x16
bit operations, with support for one 32-bit accumulator. Supported operands include 16- and 32-bit signed and unsigned
integers, signed fractional operands, and a complete set of instructions to process these data types. The MAC provides support
for execution of DSP operations within the context of a single processor at a minimal hardware cost.
1.2.3 Integrated Debug Module
The ColdFire processor core debug interface is provided to support system debugging with low-cost debug and emulator
development tools. Through a standard debug interface, access to debug information and real-time tracing capability is provided
on 100-lead packages. This allows the processor and system to be debugged at full speed without the need for costly in-circuit
emulators.
The on-chip breakpoint resources include a total of nine programmable 32-bit registers: an address and an address mask register,
a data and a data mask register, four PC registers, and one PC mask register. These registers can be accessed through the
dedicated debug serial communication channel or from the processor’s supervisor mode programming model. The breakpoint
registers can be configured to generate triggers by combining the address, data, and PC conditions in a variety of single- or
dual-level definitions. The trigger event can be programmed to generate a processor halt or initiate a debug interrupt exception.
This device implements revision B+ of the ColdFire Debug Architecture.
The processor’s interrupt servicing options during emulator mode allow real-time critical interrupt service routines to be
serviced while processing a debug interrupt event. This ensures the system continues to operate even during debugging.
To support program trace, the V2 debug module provides processor status (PST[3:0]) and debug data (DDATA[3:0]) ports.
These buses and the PSTCLK output provide execution status, captured operand data, and branch target addresses defining
processor activity at the CPU’s clock rate. The device includes a new debug signal, ALLPST. This signal is the logical AND of
the processor status (PST[3:0]) signals and is useful for detecting when the processor is in a halted state (PST[3:0] = 1111).

Family Configurations
Freescale Semiconductor9
The full debug/trace interface is available only on the 100-pin packages. However, every product features the dedicated debug
serial communication channel (DSI, DSO, DSCLK) and the ALLPST signal.
1.2.4 JTAG
The processor supports circuit board test strategies based on the Test Technology Committee of IEEE and the Joint Test Action
Group (JTAG). The test logic includes a test access port (TAP) consisting of a 16-state controller, an instruction register, and
three test registers (a 1-bit bypass register, a 256-bit boundary-scan register, and a 32-bit ID register). The boundary scan register
links the device’s pins into one shift register. Test logic, implemented using static logic design, is independent of the device
system logic.
The device implementation can:
• Perform boundary-scan operations to test circuit board electrical continuity
• Sample system pins during operation and transparently shift out the result in the boundary scan register
• Bypass the device for a given circuit board test by effectively reducing the boundary-scan register to a single bit
• Disable the output drive to pins during circuit-board testing
• Drive output pins to stable levels
1.2.5 On-Chip Memories
1.2.5.1 SRAM
The dual-ported SRAM module provides a general-purpose 8- or 16-Kbyte memory block that the ColdFire core can access in
a single cycle. The location of the memory block can be set to any 8- or 16-Kbyte boundary within the 4-Gbyte address space.
This memory is ideal for storing critical code or data structures and for use as the system stack. Because the SRAM module is
physically connected to the processor's high-speed local bus, it can quickly service core-initiated accesses or
memory-referencing commands from the debug module.
The SRAM module is also accessible by the DMA. The dual-ported nature of the SRAM makes it ideal for implementing
applications with double-buffer schemes, where the processor and a DMA device operate in alternate regions of the SRAM to
maximize system performance.
1.2.5.2 Flash Memory
The ColdFire flash module (CFM) is a non-volatile memory (NVM) module that connects to the processor’s high-speed local
bus. The CFM is constructed with up to four banks of 16-Kbyte16-bit flash memory arrays to generate up to 128 Kbytes of
32-bit flash memory. These electrically erasable and programmable arrays serve as non-volatile program and data memory. The
flash memory is ideal for program and data storage for single-chip applications, allowing for field reprogramming without
requiring an external high voltage source. The CFM interfaces to the ColdFire core through an optimized read-only memory
controller that supports interleaved accesses from the 2-cycle flash memory arrays. A backdoor mapping of the flash memory
is used for all program, erase, and verify operations, as well as providing a read datapath for the DMA. Flash memory may also
be programmed via the EzPort, which is a serial flash memory programming interface that allows the flash memory to be read,
erased and programmed by an external controller in a format compatible with most SPI bus flash memory chips.
1.2.6 Power Management
The device incorporates several low-power modes of operation entered under program control and exited by several external
trigger events. An integrated power-on reset (POR) circuit monitors the input supply and forces an MCU reset as the supply
voltage rises. The low voltage detector (LVD) monitors the supply voltage and is configurable to force a reset or interrupt
condition if it falls below the LVD trip point. The RAM standby switch provides power to RAM when the supply voltage to the
chip falls below the standby battery voltage.

Freescale Semiconductor 10
1.2.7 USB On-The-Go Controller
The device includes a Universal Serial Bus On-The-Go (USB OTG) dual-mode controller. USB is a popular standard for
connecting peripherals and portable consumer electronic devices such as digital cameras and handheld computers to host PCs.
The OTG supplement to the USB specification extends USB to peer-to-peer application, enabling devices to connect directly
to each other without the need for a PC. The dual-mode controller on the device can act as a USB OTG host and as a USB
device. It also supports full-speed and low-speed modes.
1.2.8 UARTs
The device has three full-duplex UARTs that function independently. The three UARTs can be clocked by the system bus clock,
eliminating the need for an external clock source. On smaller packages, the third UART is multiplexed with other digital I/O
functions.
1.2.9 I2C Bus
The processor includes two I2C modules. The I2C bus is an industry-standard, two-wire, bidirectional serial bus that provides
a simple, efficient method of data exchange and minimizes the interconnection between devices. This bus is suitable for
applications requiring occasional communications over a short distance between many devices.
1.2.10 QSPI
The queued serial peripheral interface (QSPI) provides a synchronous serial peripheral interface with queued transfer capability.
It allows up to 16 transfers to be queued at once, minimizing the need for CPU intervention between transfers.
1.2.11 Fast ADC
The fast ADC consists of an eight-channel input select multiplexer and two independent sample and hold (S/H) circuits feeding
separate 12-bit ADCs. The two separate converters store their results in accessible buffers for further processing.
The ADC can be configured to perform a single scan and halt, a scan when triggered, or a programmed scan sequence repeatedly
until manually stopped.
The ADC can be configured for sequential or simultaneous conversion. When configured for sequential conversions, up to eight
channels can be sampled and stored in any order specified by the channel list register. Both ADCs may be required during a
scan, depending on the inputs to be sampled.
During a simultaneous conversion, both S/H circuits are used to capture two different channels at the same time. This
configuration requires that a single channel may not be sampled by both S/H circuits simultaneously.
Optional interrupts can be generated at the end of the scan sequence if a channel is out of range (measures below the low
threshold limit or above the high threshold limit set in the limit registers) or at several different zero crossing conditions.
1.2.12 DMA Timers (DTIM0–DTIM3)
There are four independent, DMA transfer capable 32-bit timers (DTIM0, DTIM1, DTIM2, and DTIM3) on the device. Each
module incorporates a 32-bit timer with a separate register set for configuration and control. The timers can be configured to
operate from the system clock or from an external clock source using one of the DTINn signals. If the system clock is selected,
it can be divided by 16 or 1. The input clock is further divided by a user-programmable 8-bit prescaler that clocks the actual
timer counter register (TCRn). Each of these timers can be configured for input capture or reference (output) compare mode.
Timer events may optionally cause interrupt requests or DMA transfers.

1.2.13 General Purpose Timer (GPT)
The general purpose timer (GPT) is a four-channel timer module consisting of a 16-bit programmable counter driven by a
seven-stage programmable prescaler. Each of the four channels can be configured for input capture or output compare.
Additionally, channel three, can be configured as a pulse accumulator.
A timer overflow function allows software to extend the timing capability of the system beyond the 16-bit range of the counter.
The input capture and output compare functions allow simultaneous input waveform measurements and output waveform
generation. The input capture function can capture the time of a selected transition edge. The output compare function can
generate output waveforms and timer software delays. The 16-bit pulse accumulator can operate as a simple event counter or a
gated time accumulator.
1.2.14 Periodic Interrupt Timers (PIT0 and PIT1)
The two periodic interrupt timers (PIT0 and PIT1) are 16-bit timers that provide interrupts at regular intervals with minimal
processor intervention. Each timer can count down from the value written in its PIT modulus register or it can be a free-running
down-counter.
1.2.15 Real-Time Clock (RTC)
The Real-Time Clock (RTC) module maintains the system (time-of-day) clock and provides stopwatch, alarm, and interrupt
functions. It includes full clock features: seconds, minutes, hours, days and supports a host of time-of-day interrupt functions
along with an alarm interrupt.
1.2.16 Pulse-Width Modulation (PWM) Timers
The device has an 8-channel, 8-bit PWM timer. Each channel has a programmable period and duty cycle as well as a dedicated
counter. Each of the modulators can create independent continuous waveforms with software-selectable duty rates from 0% to
100%. The timer supports PCM mode, which results in superior signal quality when compared to that of a conventional PWM.
The PWM outputs have programmable polarity, and can be programmed as left aligned outputs or center aligned outputs. For
higher period and duty cycle resolution, each pair of adjacent channels ([7:6], [5:4], [3:2], and [1:0]) can be concatenated to
form a single 16-bit channel. The module can, therefore, be configured to support 8/0, 6/1, 4/2, 2/3, or 0/4 8-/16-bit channels.
1.2.17 Software Watchdog Timer
The watchdog timer is a 32-bit timer that facilitates recovery from runaway code. The watchdog counter is a free-running
down-counter that generates a reset on underflow. To prevent a reset, software must periodically restart the countdown.
1.2.18 Backup Watchdog Timer
The backup watchdog timer is an independent 16-bit timer that, like the software watchdog timer, facilitates recovery from
runaway code. This timer is a free-running down-counter that generates a reset on underflow. To prevent a reset, software must
periodically restart the countdown. The backup watchdog timer can be clocked by either the relaxation oscillator or the system
clock.
1.2.19 Phase-Locked Loop (PLL)
The clock module contains a crystal oscillator, 8 MHz on-chip relaxation oscillator (OCO), phase-locked loop (PLL), reduced
frequency divider (RFD), low-power divider status/control registers, and control logic. To improve noise immunity, the PLL,
crystal oscillator, and relaxation oscillator have their own power supply inputs: VDDPLL and VSSPLL. All other circuits are
powered by the normal supply pins, VDD and VSS.

1.2.20 Interrupt Controller (INTC)
The device has a single interrupt controller that supports up to 63 interrupt sources. There are 56 programmable sources, 49 of
which are assigned to unique peripheral interrupt requests. The remaining seven sources are unassigned and may be used for
software interrupt requests.
1.2.21 DMA Controller
The direct memory access (DMA) controller provides an efficient way to move blocks of data with minimal processor
intervention. It has four channels that allow byte, word, longword, or 16-byte burst line transfers. These transfers are triggered
by software explicitly setting a DCRn[START] bit or by the occurrence of certain UART or DMA timer events.
1.2.22 Reset
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and keeps track of what
caused the last reset. There are seven sources of reset:
• External reset input
• Power-on reset (POR)
• Watchdog timer
• Phase locked-loop (PLL) loss of lock / loss of clock
•Software
• Low-voltage detector (LVD)
•JTAG
Control of the LVD and its associated reset and interrupt are managed by the reset controller. Other registers provide status flags
indicating the last source of reset and a control bit for software assertion of the RSTO pin.
1.2.23 GPIO
Nearly all pins on the device have general purpose I/O capability and are grouped into 8-bit ports. Some ports do not use all
eight bits. Each port has registers that configure, monitor, and control the port pin.
1.2.24 Part Numbers and Packaging

1The PDSR and PSSR registers are described in the General Purpose I/O chapter. All programmable signals default to 2 mA drive and FAST slew rate in
normal (single-chip) mode.
2All signals have a pull-up in GPIO mode.
3These signals are multiplexed on other pins.
4For primary and GPIO functions only.
5Only when JTAG mode is enabled.
6CLKMOD0 and CLKMOD1 have internal pull-down resistors; however, the use of external resistors is very strongly recommended.
7When these pins are configured for USB signals, they should use the USB transceiver’s internal pull-up/pull-down resistors (see the description of the
OTG_CTRL register). If these pins are not configured for USB signals, each pin should be pulled down externally using a 10 k resistor.
8For secondary and GPIO functions only.
9RSTI has an internal pull-up resistor; however, the use of an external resistor is very strongly recommended.
10 For GPIO function. Primary Function has pull-up control within the GPT module.

1The PLL pre-divider (CCHR+1) reset value is 6 and the PLL input reference range is 2–10 MHz,
so in order to boot with the PLL enabled, the external clock or crystal frequency needs to be
greater than 12 MHz. MCF5221x devices cannot boot with PLL enabled from an external clock
or crystal oscillator with frequency less than 12 MHz. This constraint does not apply to booting
with PLL disabled.
2Cannot boot from the Internal 8 MHz Relaxation oscillator with the PLL enabled. Refer Note1.
Thus this mode has been removed from the table.

Clock
DSCLK Development Serial Clock - Internally synchronized input. (The logic
level on DSCLK is validated if it has the same value on two
consecutive rising bus clock edges.) Clocks the serial communication
port to the debug module during packet transfers. Maximum frequency
is PSTCLK/5. At the synchronized rising edge of DSCLK, the data
input on DSI is sampled and DSO changes state.
I
Breakpoint BKPT Breakpoint - Input used to request a manual breakpoint. Assertion of
BKPT puts the processor into a halted state after the current
instruction completes. Halt status is reflected on processor
status/debug data signals (PST[3:0] and PSTDDATA[7:0]) as the
value 0xF. If CSR[BKD] is set (disabling normal BKPT functionality),
asserting BKPT generates a debug interrupt exception in the
processor.
I
Development Serial
Input
DSI Development Serial Input - Internally synchronized input that provides
data input for the serial communication port to the debug module, after
the DSCLK has been seen as high (logic 1).
I
Development Serial
Output
DSO Development Serial Output - Provides serial output communication for
debug module responses. DSO is registered internally. The output is
delayed from the validation of DSCLK high.
O
Debug Data DDATA[3:0] Display captured processor data and breakpoint status. The CLKOUT
signal can be used by the development system to know when to
sample DDATA[3:0].
O
Processor Status Clock PSTCLK Processor Status Clock - Delayed version of the processor clock. Its
rising edge appears in the center of valid PST and DDATA output.
PSTCLK indicates when the development system should sample PST
and DDATA values.
If real-time trace is not used, setting CSR[PCD] keeps PSTCLK, and
PST and DDATA outputs from toggling without disabling triggers.
Non-quiescent operation can be reenabled by clearing CSR[PCD],
although the external development systems must resynchronize with
the PST and DDATA outputs.
PSTCLK starts clocking only when the first non-zero PST value (0xC,
0xD, or 0xF) occurs during system reset exception processing.
O
Processor Status
Outputs
PST[3:0] Indicate core status. Debug mode timing is synchronous with the
processor clock; status is unrelated to the current bus transfer. The
CLKOUT signal can be used by the development system to know
when to sample PST[3:0].

2 Electrical Characteristics
This section contains electrical specification tables and reference timing diagrams for the microcontroller unit, including
detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications.
The electrical specifications are preliminary and are from previous designs or design simulations. These specifications may not
be fully tested or guaranteed at this early stage of the product life cycle. These specifications will, however, be met for
production silicon. Finalized specifications will be published after complete characterization and device qualifications have
been completed.
NOTE
The parameters specified in this data sheet supersede any values found in the module
specifications.
2.1 Maximum Ratings
Table 19. Absolute Maximum Ratings1, 2
1Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum Ratings
are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond
those listed may affect device reliability or cause permanent damage to the device.
2This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher
than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if
unused inputs are tied to an appropriate logic voltage level (VSS or VDD).

3Input must be current limited to the IDD value specified. To determine the value of the required
current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then
use the larger of the two values.

EXTAL pin voltage VEXTAL 0 to 3.3 V
XTAL pin voltage VXTAL 0 to 3.3 V
Instantaneous maximum current
Single pin limit (applies to all pins)4, 5
4All functional non-supply pins are internally clamped to VSS and VDD.
5The power supply must maintain regulation within operating VDD range during instantaneous and
operating maximum current conditions. If positive injection current (Vin > VDD) is greater than IDD, the
injection current may flow out of VDD and could result in the external power supply going out of
regulation. Ensure that the external VDD load shunts current greater than maximum injection current.
This is the greatest risk when the MCU is not consuming power (e.g., no clock).

2.4 Flash Memory Characteristics
The flash memory characteristics are shown in Table 23 and Table 24.
1JA and jt parameters are simulated in conformance with EIA/JESD Standard 51-2 for natural convection. Freescale
recommends the use of JA and power dissipation specifications in the system design to prevent device junction
temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures
can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature
specification can be verified by physical measurement in the customer’s system using the jt parameter, the device power
dissipation, and the method described in EIA/JESD Standard 51-2.

3Per JEDEC JESD51-6 with the board JESD51-7) horizontal.
4Thermal resistance between the die and the printed circuit board in conformance with JEDEC JESD51-8. Board
temperature is measured on the top surface of the board near the package.
5Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883
Method 1012.1).
6Thermal characterization parameter indicating the temperature difference between package top and the junction
temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written
in conformance with Psi-JT.
The average chip-junction temperature (TJ) in C can be obtained from:
(1)
Where:
TA= ambient temperature, C
JA = package thermal resistance, junction-to-ambient, C/W
PD= PINT PI/O
PINT = chip internal power, IDD VDD, watts
PI/O = power dissipation on input and output pins — user determined, watts
For most applications PI/O PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is:
(2)
Solving equations 1 and 2 for K gives:
K = PD (TA + 273 C) + JMA PD 2 (3)
where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for
any value of TA.

5Loss of Reference Frequency is the reference frequency detected internally, which transitions the PLL into self clocked mode.
6Self clocked mode frequency is the frequency at which the PLL operates when the reference frequency falls below fLOR with
default MFD/RFD settings.
7This parameter is characterized before qualification rather than 100% tested.
8Proper PC board layout procedures must be followed to achieve specifications.
9This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the

10 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the PLL circuitry via VDDPLL and VSSPLL and variation in crystal oscillator frequency increase the Cjitter percentage
for a given interval.

2.14 Equivalent Circuit for ADC Inputs
Figure 8 shows the ADC input circuit during sample and hold. S1 and S2 are always open/closed at the same time that S3 is
closed/open. When S1/S2 are closed & S3 is open, one input of the sample and hold circuit moves to (VREFH-VREFL)/2, while
the other charges to the analog input voltage. When the switches are flipped, the charge on C1 and C2 are averaged via S3, with
the result that a single-ended analog input is switched to a differential voltage centered about (VREFH-VREFL)/2. The switches
switch on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). There are additional
capacitances associated with the analog input pad, routing, etc., but these do not filter into the S/H output voltage, as S1 provides
isolation during the charge-sharing phase. One aspect of this circuit is that there is an on-going input current, which is a function
of the analog input voltage, VREF and the ADC clock frequency.
1. Parasitic capacitance due to package, pin-to-pin and pin-to-package base coupling; 1.8pF
2. Parasitic capacitance due to the chip bond pad, ESD protection devices and signal routing; 2.04pF
3. Equivalent resistance for the channel select mux; 100 s
4. Sampling capacitor at the sample and hold circuit. Capacitor C1 is normally disconnected from the input and is only
connected to it at sampling time; 1.4pF
5. Equivalent input impedance, when the input is selected =
