Signal Descriptions
Signal Descriptions
Signal descriptions are in the reference manual. Special signal considerations are listed following this
paragraph. The BGA ball assignment is in Section 5, “Package Information and Pinout.”
Special Signal Considerations:
• Tamper detect (GPIO1_6)
Tamper detect logic is used to issue a security violation. This logic is activated if the tamper detect
input is asserted.
The tamper detect logic is disabled after reset. After enabling the logic, it is impossible to disable
it until the next reset. The GPR[16] bit functions as the tamper detect enable bit.
GPIO1_6 functions similarly to other I/O with GPIO capabilities regardless of the status of the
tamper detect enable bit. (For example, the GPIO1_6 can function as an input with GPIO
capabilities, such as sampling through PSR or generating interrupts.)
• Power ready (GPIO1_5)
The power ready input, GPIO1_5, should be connected to an external power management IC power
ready output signal. If not used, GPIO1_5 must either be (a) externally pulled-up to NVCC1 or (b)
a no connect, internally pulled-up by enabling the on-chip pull-up resistor. GPIO1_5 is a dedicated
input and cannot be used as a general-purpose input/output.
• SJC_MOD
SJC_MOD must be externally connected to GND for normal operation. Termination to GND
through an external pull-down resistor (such as 1 kΩ) is allowed, but the value should be much
smaller than the on-chip 100 kΩ pull-up.
• CE_CONTROL
CE_CONTROL is a reserved input and must be externally tied to GND through a 1 kΩ resistor.
• TTM_PAD
TTM_PAD is for Freescale factory use only. Control bits indicate pull-up/down disabled. However,
TTM_PAD is actually connected to an on-chip pull-down device. Users must either float this signal
or tie it to GND.
• M_REQUEST and M_GRANT
These two signals are not utilized internally. The user should make no connection to these signals.
• Clock Source Select (CLKSS)
The CLKSS is the input that selects the default reference clock source providing input to the DPLL.
To select CKIH, tie CLKSS to NVCC1. To select CKIL, tie CLKSS to ground. After initialization,
the reference clock source can be changed (initial setting is overwritten) by programming the
PRCS bits in the CCMR.

Measured at package balls, including peripherals, ARM, and L2 cache supplies (QVCC, QVCC1, QVCC4, respectively).
The core voltage must be higher than 1.38V to avoid corrupted data during transfers from the USB HS. Please refer to Errata
file ENGcm02610 ID.
If the Core voltage is supplied by the MC13738, it will be 1.6 ± 0.05 V during the power-up sequence. This is allowed. After
power-up the voltage should be reduced to avoid operation in overdrive mode.
Supply voltage is considered “overdrive” for voltages above 1.47 V. Operation time in overdrive—whether switching or
not—must be limited to a cumulative duration of 1.25 years (10,950 hours) or less to sustain the maximum operating voltage
without significant device degradation—for example, 25% (average 6 hours out of 24 yours per day) duty cycle for 5-year rated
equipment. To tolerate the maximum operating overdrive voltage for 10 years, the device must have a duty cycle of 12.5% or
less in overdrive (for example 3 out of 24 hours per day). Below 1.47V, duty cycle restrictions may apply for equipment rated
above 5 years.
The SR voltage is applied to QVCC, QVCC1, and QVCC4 after the device is placed in SR mode. The Real-Time Clock (RTC)
is operational in State Retention (SR) mode.
Overshoot and undershoot conditions (transitions above NVCC and below GND) on I/O must be held below 0.6 V, and the
duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/undershoot must be
controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other
methods. Non-compliance to this specification may affect device reliability or cause permanent damage to the device.

Table 8 provides the operating ranges.
Electrical Characteristics
Supply voltage is considered “overdrive” for voltages above 3.1 V. Operation time in overdrive—whether switching or
not—must be limited to a cumulative duration of 1 year (8,760 hours) or less to sustain the maximum operating voltage without
significant device degradation—for example, 20% (average 4.8 hours out of 24 hours per day) duty cycle for 5-year rated
equipment. Operation at 3.3 V that exceeds a cumulative 3,504 hours may cause non-operation whenever supply voltage is
reduced to 1.8 V; degradation may render the device too slow or inoperable. Below 3.1 V, duty cycle restrictions may apply for
equipment rated above 5 years.
8
For normal operating conditions, PLLs’ and core supplies must maintain the following relation: PLL ≥ Core – 100 mV. In other
words, for a 1.6 V core supply, PLL supplies must be set to 1.5 V or higher. This restriction is no longer necessary on mask
set M91E. PLL supplies may be set independently of core supply. PLL voltage must not be altered after power up, otherwise
the PLL will be unstable and lose lock. To minimize inducing noise on the PLL supply line, source the voltage from a low-noise,
dedicated supply. PLL parameters in Table 31, "DPLL Specifications," on page 37, are guaranteed over the entire specified
voltage range.

Supply Power-Up/Power-Down Requirements and Restrictions
Any MCIMX31 board design must comply with the power-up and power-down sequence guidelines as
described in this section to guarantee reliable operation of the device. Any deviation from these sequences
may result in any or all of the following situations:
• Cause excessive current during power up phase
• Prevent the device from booting
• Cause irreversible damage to the MCIMX31 (worst-case scenario)
4.2.1
Powering Up
The Power On Reset (POR) pin must be kept asserted (low) throughout the power up sequence. Power up
logic must guarantee that all power sources reach their target values prior to the release (de-assertion) of
POR. Figure 2 shows the power-up sequence for silicon Revisions 1.2 and previous. Figure 3 and Figure 4
show the power-up sequence for silicon Revision 2.0.
NOTE
Stages need to be performed in the order shown; however, within each stage,
supplies can be powered up in any order. For example, supplies IOQVDD,
NVCC1, and NVCC3 through NVCC10 do not need to be powered up in the
order shown.
CAUTION
NVCC6 and NVCC9 must be at the same voltage potential. These supplies
are connected together on-chip to optimize ESD damage immunity.

Power-Up Sequence for Silicon Revision 2
Silicon revision 2.0 offers two options for power-up sequencing. Option 1 is backwards compatible with
silicon revision 1.2 and earlier versions of the IC. It should be noted that using option 1 on silicon Rev. 2.0
introduces a slight increase in current drain on IOQVDD when IOQVDD is raised before NVCC21. The
expected resulting increase is in the range of 3 mA to 5 mA, which does not pose a risk to the IC.
Option 2 is an alternative power-up sequence that allows the powering up of NVCC2, NVCC21, NVCC22
with IOQVDD, NVCC1, and NVCC3-10 without producing a current drain increase on IOQVDD.
These two power-up options on the 2.0 silicon allow the user to select the optimum power-up sequence for
their application.

The board design must guarantee that supplies reach

The NVCC1 supply must not precede IOQVDD by more
than 0.2 V until IOQVDD has reached 1.5 V. If IOQVDD
is powered up first, there are no restrictions.
The parallel paths in the flow indicate that supply group
NVCC2, NVCC21, and NVCC22, and supply group
FVCC, MVCC, SVCC, and UVCC ramp-ups are
independent. Note that this power-up sequence is
backward compatible to Silicon Revs. 1.15 and 1.2,
because NVCC2x ramp-up proceeding PLL supplies is
allowed.
Unlike the power-up sequence for Silicon Revision 1.2,
FUSE_VDD should not be driven on power-up for Silicon
Revision 2.0. This supply is dedicated for fuse burning
(programming), and should not be driven upon boot-up.
Raising IOQVDD before NVCC21 produces a slight
increase in current drain on IOQVDD of approximately
3–5 mA. The current increase will not damage the IC.

The board design must guarantee that supplies reach
90% level before transition to the next state, using Power
Management IC or other means.
The NVCC1 supply must not precede IOQVDD by more
than 0.2 V until IOQVDD has reached 1.5 V. If IOQVDD
is powered up first, there are no restrictions.
Raising NVCC2, NVCC21, and NVCC22 at the same
time as IOQVDD does not produce the slight increase in
current drain on IOQVDD (as described in Figure 3,
Note 5).
Unlike the power-up sequence for Silicon Revision 1.2,
FUSE_VDD should not be driven on power-up for Silicon
Revision 2.0. This supply is dedicated for fuse burning
(programming), and should not be driven upon boot-up.

Powering Down
The power-down sequence prior to silicon Revision 2.0 should be completed as follows:
1. Lower the FUSE_VDD supply (when in write mode).
2. Lower the remaining supplies.
For silicon revisions beginning with Revision 2.0 there is no special requirements for power down
sequence.

I/O Pad (PADIO) Electrical Specifications
This section specifies the AC/DC characterization of functional I/O of the MCIMX31. There are two main
types of I/O: regular and DDR. In this document, the “Regular” type is referred to as GPIO.
4.3.1.1
DC Electrical Characteristics
The MCIMX31 I/O parameters appear in Table 15 for GPIO. See Table 8 for temperature and supply
voltage ranges.
NOTE
The term NVCC in this section refers to the associated supply rail of an
input or output. The association is shown in the Signal Multiplexing chapter
of the reference manual. NVCC for Table 15 refers to NVCC1 and
NVCC3–10; QVCC refers to QVCC, QVCC1, and QVCC4.

ATA Electrical Specifications (ATA Bus, Bus Buffers)
This section discusses ATA parameters. For a detailed description, refer to the ATA specification.
The user needs to use level shifters for 3.3 Volt or 5.0 Volt compatibility on the ATA interface.
The use of bus buffers introduces delay on the bus and introduces skew between signal lines. These factors
make it difficult to operate the bus at the highest speed (UDMA-5) when bus buffers are used. If fast
UDMA mode operation is needed, this may not be compatible with bus buffers.
Another area of attention is the slew rate limit imposed by the ATA specification on the ATA bus.
According to this limit, any signal driven on the bus should have a slew rate between 0.4 and 1.2 V/ns with
a 40 pF load. Not many vendors of bus buffers specify slew rate of the outgoing signals.
When bus buffers are used, the ata_data bus buffer is special. This is a bidirectional bus buffer, so a
direction control signal is needed. This direction control signal is ata_buffer_en. When its high, the bus
should drive from host to device. When its low, the bus should drive from device to host. Steering of the
signal is such that contention on the host and device tri-state busses is always avoided.

The user or board designer must take into account that the use of a frequency other than 26 MHz would require adjustment to
the DPTC–DVFS table, which is incorporated into operating system code.
2 The PLL reference frequency must be ≤ 35 MHz. Therefore, for frequencies between 35 MHz and 70 MHz, program the
predivider to divide by 2 or more. If the CKIH frequency is above 70 MHz, program the predivider to 3 or more. For PD bit

NOTE
High is defined as 80% of signal value and low is defined as 20% of signal
value.
Timing for HCLK is 133 MHz and internal NFC clock (flash clock) is
approximately 33 MHz (30 ns). All timings are listed according to this NFC
clock frequency (multiples of NFC clock phases), except NF16 and NF17,
which are not NFC clock related.

Wireless External Interface Module (WEIM)
All WEIM output control signals may be asserted and deasserted by internal clock related to BCLK rising
edge or falling edge according to corresponding assertion/negation control fields. Address always begins
related to BCLK falling edge but may be ended both on rising and falling edge in muxed mode according
to control register configuration. Output data begins related to BCLK rising edge except in muxed mode
where both rising and falling edge may be used according to control register configuration. Input data,
ECB and DTACK all captured according to BCLK rising edge time. Figure 27 depicts the timing of the
WEIM module, and Table 33 lists the timing parameters.

Timing parameters are relevant only to SDR SDRAM. For the specific DDR SDRAM data related timing parameters, see
Table 38 and Table 39.
NOTE
SDR SDRAM CLK parameters are being measured from the 50%
point—that is, high is defined as 50% of signal value and low is defined as
50% of signal value. SD1 + SD2 does not exceed 7.5 ns for 133 MHz.
The timing parameters are similar to the ones used in SDRAM data
sheets—that is, Table 34 indicates SDRAM requirements. All output signals
are driven by the ESDCTL at the negative edge of SDCLK and the
parameters are measured at maximum memory frequency.

A device must internally provide a hold time of at least 300 ns for I2DAT signal in order to bridge the undefined region of the
falling edge of I2CLK.
2 The maximum hold time has to be met only if the device does not stretch the LOW period (ID IC6) of the I2CLK signal.
3 A Fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement of set-up time (ID IC7) of
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the I2CLK signal.
If such a device does stretch the LOW period of the I2CLK signal, it must output the next data bit to the I2DAT line max_rise_time
(ID No IC10) + data_setup_time (ID No IC8) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification)
before the I2CLK line is released.

4.3.14.2
Functional Description
There are three timing modes supported by the IPU.
4.3.14.2.1
Pseudo BT.656 Video Mode
Smart camera sensors, which include imaging processing, usually support video mode transfer. They use
an embedded timing syntax to replace the SENSB_VSYNC and SENSB_HSYNC signals. The timing
syntax is defined by the BT.656 standard.
This operation mode follows the recommendations of ITU BT.656 specifications. The only control signal
used is SENSB_PIX_CLK. Start-of-frame and active-line signals are embedded in the data stream. An
active line starts with a SAV code and ends with a EAV code. In some cases, digital blanking is inserted in
between EAV and SAV code. The CSI decodes and filters out the timing-coding from the data stream, thus
recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use.

Figure 43. Gated Clock Mode Timing Diagram
A frame starts with a rising edge on SENSB_VSYNC (all the timings correspond to straight polarity of the
corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. Pixel clock is valid
as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks.
SENSB_HSYNC goes to low at the end of line. Pixel clocks then become invalid and the CSI stops
receiving data from the stream. For next line the SENSB_HSYNC timing repeats. For next frame the
SENSB_VSYNC timing repeats.
4.3.14.2.3
Non-Gated Clock Mode
The timing is the same as the gated-clock mode (described in Section 4.3.14.2.2, “Gated Clock Mode”),
except for the SENSB_HSYNC signal, which is not used. See Figure 44. All incoming pixel clocks are
valid and will cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states
low) until valid data is going to be transmitted over the bus.

4.3.14.2.2
The timing described in Figure 44 is that of a Motorola sensor. Some other sensors may have a slightly
different timing. The CSI can be programmed to support rising/falling-edge triggered SENSB_VSYNC;
active-high/low SENSB_HSYNC; and rising/falling-edge triggered SENSB_PIX_CLK.

the clock is inverted and all timing specifications will remain the same but are referenced to the falling edge of
the clock.

Figure 46 depicts the LCD interface timing for a generic active matrix color TFT panel. In this figure
signals are shown with negative polarity. The sequence of events for active matrix interface timing is:
• DISPB_D3_CLK latches data into the panel on its negative edge (when positive polarity is
selected). In active mode, DISPB_D3_CLK runs continuously.
• DISPB_D3_HSYNC causes the panel to start a new line.
• DISPB_D3_VSYNC causes the panel to start a new frame. It always encompasses at least one
HSYNC pulse.

NOTE
HSP_CLK is the High-Speed Port Clock, which is the input to the Image
Processing Unit (IPU). Its frequency is controlled by the Clock Control
Module (CCM) settings. The HSP_CLK frequency must be greater than or
equal to the AHB clock frequency.
The SCREEN_WIDTH, SCREEN_HEIGHT, H_SYNC_WIDTH, V_SYNC_WIDTH, BGXP, BGYP and
V_SYNC_WIDTH_L parameters are programmed via the SDC_HOR_CONF, SDC_VER_CONF,
SDC_BG_POS Registers. The FW and FH parameters are programmed for the corresponding DMA
channel. The DISP3_IF_CLK_PER_WR, HSP_CLK_PERIOD and DISP3_IF_CLK_CNT_D parameters
are programmed via the DI_DISP3_TIME_CONF, DI_HSP_CLK_PER and DI_DISP_ACC_CC
Registers.
Figure 49 depicts the synchronous display interface timing for access level, and Table 48 lists the timing
parameters. The DISP3_IF_CLK_DOWN_WR and DISP3_IF_CLK_UP_WR parameters are set via the
DI_DISP3_TIME_CONF Register.

Synchronous Interface to Dual-Port Smart Displays
Functionality and electrical characteristics of the synchronous interface to dual-port smart displays are
identical to parameters of the synchronous interface. See Section 4.3.15.2.2, “Interface to Active Matrix
TFT LCD Panels, Electrical Characteristics.”
4.3.15.4.1
Interface to a TV Encoder, Functional Description
The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The bits
D7–D0 of the value are mapped to bits LD17–LD10 of the data bus, respectively. Figure 51 depicts the
interface timing,
• The frequency of the clock DISPB_D3_CLK is 27 MHz (within 10%).
• The DISPB_D3_HSYNC, DISPB_D3_VSYNC and DISPB_D3_DRDY signals are active low.
• The transition to the next row is marked by the negative edge of the DISPB_D3_HSYNC signal. It
remains low for a single clock cycle.
• The transition to the next field/frame is marked by the negative edge of the DISPB_D3_VSYNC
signal. It remains low for at least one clock cycle.
— At a transition to an odd field (of the next frame), the negative edges of DISPB_D3_VSYNC
and DISPB_D3_HSYNC coincide.
— At a transition to an even field (of the same frame), they do not coincide.
• The active intervals—during which data is transferred—are marked by the DISPB_D3_HSYNC
signal being high.

Asynchronous Interfaces
Parallel Interfaces, Functional Description
The IPU supports the following asynchronous parallel interfaces:
• System 80 interface
— Type 1 (sampling with the chip select signal) with and without byte enable signals.
— Type 2 (sampling with the read and write signals) with and without byte enable signals.
• System 68k interface
— Type 1 (sampling with the chip select signal) with or without byte enable signals.
— Type 2 (sampling with the read and write signals) with or without byte enable signals.
For each of four system interfaces, there are three burst modes:
1. Burst mode without a separate clock. The burst length is defined by the corresponding parameters
of the IDMAC (when data is transferred from the system memory) of by the HBURST signal (when
the MCU directly accesses the display via the slave AHB bus). For system 80 and system 68k type
1 interfaces, data is sampled by the CS signal and other control signals changes only when transfer
direction is changed during the burst. For type 2 interfaces, data is sampled by the WR/RD signals
(system 80) or by the ENABLE signal (system 68k) and the CS signal stays active during the whole
burst.
2. Burst mode with the separate clock DISPB_BCLK. In this mode, data is sampled with the
DISPB_BCLK clock. The CS signal stays active during whole burst transfer. Other controls are
changed simultaneously with data when the bus state (read, write or wait) is altered. The CS
signals and other controls move to non-active state after burst has been completed.
3. Single access mode. In this mode, slave AHB and DMA burst are broken to single accesses. The
data is sampled with CS or other controls according the interface type as described above. All
controls (including CS) become non-active for one display interface clock after each access. This
mode corresponds to the ATI single access mode.
Both system 80 and system 68k interfaces are supported for all described modes as depicted in Figure 52,
Figure 53, Figure 54, and Figure 55. These timing images correspond to active-low DISPB_D#_CS,
DISPB_D#_WR and DISPB_D#_RD signals.
Additionally, the IPU allows a programmable pause between two burst. The pause is defined in the
HSP_CLK cycles. It allows to avoid timing violation between two sequential bursts or two accesses to
different displays. The range of this pause is from 4 to 19 HSP_CLK cycles.

Serial Interfaces, Functional Description
The IPU supports the following types of asynchronous serial interfaces:
• 3-wire (with bidirectional data line)
• 4-wire (with separate data input and output lines)
• 5-wire type 1 (with sampling RS by the serial clock)
• 5-wire type 2 (with sampling RS by the chip select signal)
Figure 61 depicts timing of the 3-wire serial interface. The timing images correspond to active-low
DISPB_D#_CS signal and the straight polarity of the DISPB_SD_D_CLK signal.
For this interface, a bidirectional data line is used outside the device. The IPU still uses separate input and
output data lines (IPP_IND_DISPB_SD_D and IPP_DO_DISPB_SD_D). The I/O mux should provide
joining the internal data lines to the bidirectional external line according to the IPP_OBE_DISPB_SD_D
signal provided by the IPU.
Each data transfer can be preceded by an optional preamble with programmable length and contents. The
preamble is followed by read/write (RW) and address (RS) bits. The order of the these bits is
programmable. The RW bit can be disabled. The following data can consist of one word or of a whole
burst. The interface parameters are controlled by the DI_SER_DISP1_CONF and DI_SER_DISP2_CONF
Registers.

The interface is meant to be used with synchronous SIM cards. This means that the SIM module provides
a clock for the SIM card to use. The frequency of this clock is normally 372 times the data rate on the
TX/RX pins, however SIM module can work with CLK equal to 16 times the data rate on TX/RX pins.
There is no timing relationship between the clock and the data. The clock that the SIM module provides
to the aim card will be used by the SIM card to recover the clock from the data much like a standard UART.
All six (or 5 in case bi-directional TXRX is used) of the pins for each half of the SIM module are
asynchronous to each other.
There are no required timing relationships between the signals in normal mode, but there are some in two
specific cases: reset and power down sequences.

Reset Sequence
Cards with Internal Reset
The sequence of reset for this kind of SIM Cards is as follows (see Figure 74):
• After powerup, the clock signal is enabled on SGCLK (time T0)
• After 200 clock cycles, RX must be high.
• The card must send a response on RX acknowledging the reset between 400 and 40000 clock cycles
after T0.

Cards with Active Low Reset
The sequence of reset for this kind of card is as follows (see Figure 75):
1. After powerup, the clock signal is enabled on CLK (time T0)
2. After 200 clock cycles, RX must be high.
3. RST must remain Low for at least 40000 clock cycles after T0 (no response is to be received on
RX during those 40000 clock cycles)
4. RST is set High (time T1)
5. RST must remain High for at least 40000 clock cycles after T1 and a response must be received
on RX between 400 and 40000 clock cycles after T1.

Power Down Sequence
Power down sequence for SIM interface is as follows:
1. SIMPD port detects the removal of the SIM Card
2. RST goes Low
3. CLK goes Low
4. TX goes Low
5. VEN goes Low
Each of this steps is done in one CKIL period (usually 32 kHz). Power down can be started because of a
SIM Card removal detection or launched by the processor. Figure 76 and Table 58 show the usual timing
requirements for this sequence, with Fckil = CKIL frequency value.

On cases where SDMA TAP is put in the chain, the max TCK frequency is limited by max ratio of 1:8 of SDMA core frequency
to TCK limitation. This implies max frequency of 8.25 MHz (or 121.2 ns) for 66 MHz IPG clock.

SSI Electrical Specifications
This section describes the electrical information of SSI. Note the following pertaining to timing
information:
• All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP/RSCKP = 0)
and a non-inverted frame sync (TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync
have been inverted, all the timing remains valid by inverting the clock signal STCK/SRCK and/or
the frame sync STFS/SRFS shown in the tables and in the figures.
• All timings are on AUDMUX signals when SSI is being used for data transfer.
• “Tx” and “Rx” refer to the Transmit and Receive sections of the SSI.
• For internal Frame Sync operation using external clock, the FS timing will be same as that of Tx
Data (for example, during AC97 mode of operation).
