Freescale Semiconductor, Inc.
Terminology and guidelines
• During normal operation, don’t exceed any of the chip’s operating requirements.
• If you must exceed an operating requirement at times other than during normal
operation (for example, during power sequencing), limit the duration as much as
possible.
3.8 Definition: Typical value
A typical value is a specified value for a technical characteristic that:
• Lies within the range of values specified by the operating behavior
• Given the typical manufacturing process, is representative of that characteristic
during operation when you meet the typical-value conditions or other specified
conditions
Typical values are provided as design guidelines and are neither tested nor guaranteed.

1. The device always interprets an input as a 1 when the input is greater than or equal to VIH (min.) and less than or equal to
VIH (max.), regardless of whether input hysteresis is turned on.
2. The device always interprets an input as a 0 when the input is less than or equal to VIL (max.) and greater than or equal to
VIL (min.), regardless of whether input hysteresis is turned on.
3. All functional non-supply pins are internally clamped to VSS and VDD. Input must be current limited to the 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. 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 external power supply going out of regulation. Ensure external
VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not
consuming power. Examples are: if no system clock is present, or if clock rate is very low (which would reduce overall
power consumption).

mode).
2. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=0.
3. The resulting system clock frequencies should not exceed their maximum specified values. The DCO frequency deviation
(Δfdco_t) over voltage and temperature should be considered.
4. These typical values listed are with the slow internal reference clock (FEI) using factory trim and DMX32=1.
5. The resulting clock frequency must not exceed the maximum specified clock frequency of the device.

6. This specification applies to any time the FLL reference source or reference divider is changed, trim value is changed,
DMX32 bit is changed, DRS bits are changed, or changing from FLL disabled (BLPE, BLPI) to FLL enabled (FEI, FEE,
FBE, FBI). If a crystal/resonator is being used as the reference, this specification assumes it is already running.
7. Excludes any oscillator currents that are also consuming power while PLL is in operation.
8. This specification was obtained using a Freescale developed PCB. PLL jitter is dependent on the noise characteristics of
each PCB and results will vary.
9. This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled
(BLPE, BLPI) to PLL enabled (PBE, PEE). If a crystal/resonator is being used as the reference, this specification assumes

1. Other frequency limits may apply when external clock is being used as a reference for the FLL or PLL.
2. When transitioning from FBE to FEI mode, restrict the frequency of the input clock so that, when it is divided by FRDIV, it
remains within the limits of the DCO input clock frequency.
3. Proper PC board layout procedures must be followed to achieve specifications.
4. Crystal startup time is defined as the time between the oscillator being enabled and the OSCINIT bit in the MCG_S register
being set.

1. Typical data retention values are based on measured response accelerated at high temperature and derated to a constant
25°C use profile. Engineering Bulletin EB618 does not apply to this technology.
2. Data retention is based on Tjavg = 55°C (temperature profile over the lifetime of the application).
3. Cycling endurance represents number of program/erase cycles at -40°C ≤ Tj ≤ 125°C.
4. Write endurance represents the number of writes to each FlexRAM location at -40°C ≤Tj ≤ 125°C influenced by the cycling
endurance of the FlexNVM (same value as data flash) and the allocated EEPROM backup. Minimum and typical values
assume all byte-writes to FlexRAM.
6.4.1.5 Write endurance to FlexRAM for EEPROM
When the FlexNVM partition code is not set to full data flash, the EEPROM data set size
can be set to any of several non-zero values.
MCF51QU128 Data Sheet, Rev. 4, 01/2012.

Freescale Semiconductor, Inc.
Memories and memory interfaces
The bytes not assigned to data flash via the FlexNVM partition code are used by the
FTFL to obtain an effective endurance increase for the EEPROM data. The built-in
EEPROM record management system raises the number of program/erase cycles that can
be attained prior to device wear-out by cycling the EEPROM data through a larger
EEPROM NVM storage space.
While different partitions of the FlexNVM are available, the intention is that a single
choice for the FlexNVM partition code and EEPROM data set size is used throughout the
entire lifetime of a given application. The EEPROM endurance equation and graph
shown below assume that only one configuration is ever used.
EEPROM – 2 × EEESIZE
Writes_FlexRAM =
× Write_efficiency × nnvmcycd
where
• Writes_FlexRAM — minimum number of writes to each FlexRAM location
• EEPROM — allocated FlexNVM based on DEPART; entered with Program
Partition command
• EEESIZE — allocated FlexRAM based on DEPART; entered with Program Partition
command
• Write_efficiency —
• 0.25 for 8-bit writes to FlexRAM
• 0.50 for 16-bit or 32-bit writes to FlexRAM
• nnvmcycd — data flash cycling endurance

6.4.3 Mini-Flexbus Switching Specifications
All processor bus timings are synchronous; input setup/hold and output delay are given in
respect to the rising edge of a reference clock, FB_CLK. The FB_CLK frequency may be
the same as the internal system bus frequency or an integer divider of that frequency.
The following timing numbers indicate when data is latched or driven onto the external
bus, relative to the Mini-Flexbus output clock (FB_CLK). All other timing relationships
can be derived from these values.

3. This resistance is external to MCU. The analog source resistance should be kept as low as possible in order to achieve the
best results. The results in this datasheet were derived from a system which has <8 Ω analog source resistance. The RAS

2. Typical values assume VDDA = 3.0 V, Temp = 25°C, fADCK = 2.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
3. The ADC supply current depends on the ADC conversion clock speed, conversion rate and the ADLPC bit (low power).
For lowest power operation the ADLPC bit should be set, the HSC bit should be clear with 1MHz ADC conversion clock

6.8.1 SPI switching specifications
The Serial Peripheral Interface (SPI) provides a synchronous serial bus with master and
slave operations. Many of the transfer attributes are programmable. The following tables
provide timing characteristics for classic SPI timing modes. See the SPI chapter of the
chip's Reference Manual for information about the modified transfer formats used for
communicating with slower peripheral devices.
All timing is shown with respect to 20% VDD and 70% VDD, unless noted, as well as
input signal transitions of 3 ns and a 50 pF maximum load on all SPI pins. All timing
assumes slew rate control is disabled and high drive strength is enabled for SPI output
pins.

1. The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.
2. CAPTRM=7, DELVOL=7, and fixed external capacitance of 20 pF.
3. CAPTRM=0, DELVOL=2, and fixed external capacitance of 20 pF.
4. CAPTRM=0, EXTCHRG=9, and fixed external capacitance of 20 pF.
5. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.
6. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current.
7. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
8. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
10. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes, it is equal to (Cref
* Iext)/( Iref * PS * NSCN). Sensitivity depends on the configuration used. The typical value listed is based on the following
configuration: Iext = 5 μA, EXTCHRG = 4, PS = 128, NSCN = 2, Iref = 16 μA, REFCHRG = 15, Cref = 1.0 pF. The
minimum sensitivity describes the smallest possible capacitance that can be measured by a single count (this is the best
sensitivity but is described as a minimum because it’s the smallest number). The minimum sensitivity parameter is based
on the following configuration: Iext = 1 μA, EXTCHRG = 0, PS = 128, NSCN = 32, Iref = 32 μA, REFCHRG = 31, Cref= 0.5
pF
11. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1
electrode, DELVOL = 2, EXTCHRG = 15.
12. CAPTRM=7, DELVOL=2, REFCHRG=0, EXTCHRG=4, PS=7, NSCN=0F, LPSCNITV=F, LPO is selected (1 kHz), and
fixed external capacitance of 20 pF. Data is captured with an average of 7 periods window.

8.2 Pinout diagrams
The following diagrams show pinouts for the 64-pin, 48-pin, 44-pin, and 32-pin
packages. These diagrams are representations for ease of reference. See the package
drawings for mechanical details.
For each pin, the diagrams show the default function or (when disabled is the default) the
ALT1 signal for a GPIO function. However, many signals may be multiplexed onto a
single pin.
