UJA1169
Mini high-speed CAN system basis chip
Rev. 1 — 4 February 2016
Product data sheet
1. General description
The UJA1169 is a mini high-speed CAN System Basis Chip (SBC) containing an
ISO 11898-2:201x (upcoming merged ISO 11898-2/5/6) compliant HS-CAN transceiver
and an integrated 5 V or 3.3 V 250 mA scalable supply (V1) for a microcontroller and/or
other loads. It also features a watchdog and a Serial Peripheral Interface (SPI). The
UJA1169 can be operated in very low-current Standby and Sleep modes with bus and
local wake-up capability.
The UJA1169 comes in six variants. The UJA1169TK, UJA1169TK/F, UJA1169TK/X and
UJA1169TK/X/F contain a 5 V regulator (V1). V1 is a 3.3 V regulator in the UJA1169TK/3
and the UJA1169TK/F/3.
The UJA1169TK, UJA1169TK/F, UJA1169TK/3 and UJA1169TK/F/3 variants feature a
second on-board 5 V regulator (V2) that supplies the internal CAN transceiver and can
also be used to supply additional on-board hardware.
The UJA1169TK/X and UJA1169TK/X/F are equipped with a 5 V supply (VEXT) for
off-board components. VEXT is short-circuit proof to the battery, ground and negative
voltages. The integrated CAN transceiver is supplied internally via V1, in parallel with the
microcontroller.
The UJA1169xx/F variants support ISO 11898-6:2013 and ISO 11898-2:201x compliant
CAN partial networking with a selective wake-up function incorporating CAN FD-passive.
CAN FD-passive is a feature that allows CAN FD bus traffic to be ignored in
Sleep/Standby mode. CAN FD-passive partial networking is the perfect fit for networks
that support both CAN FD and classic CAN communications. It allows normal CAN
controllers that do not need to communicate CAN FD messages to remain in partial
networking Sleep/Standby mode during CAN FD communication without generating bus
errors.
The UJA1169 implements the standard CAN physical layer as defined in the current
ISO11898 standard (-2:2003, -5:2007, -6:2013). Pending the release of the upcoming
version of ISO11898-2:201x including CAN FD, additional timing parameters defining loop
delay symmetry are included. This implementation enables reliable communication in the
CAN FD fast phase at data rates up to 2 Mbit/s.
A dedicated LIMP output pin is provided to flag system failures.
A number of configuration settings are stored in non-volatile memory. This arrangement
makes it possible to configure the power-on and limp-home behavior of the UJA1169 to
meet the requirements of different applications.

(CAN Offline mode). The autonomous CAN bias voltage is derived directly from VBAT.
7.7.1 CAN operating modes
The integrated CAN transceiver supports four operating modes: Active, Listen-only,
Offline and Offline Bias (see Figure 9). The CAN transceiver operating mode depends on
the UJA1169 operating mode and on the setting of bits CMC in the CAN control register
(Table 15).

UJA1169
NXP Semiconductors
Mini high-speed CAN SBC with optional partial networking
When the UJA1169 is in Normal mode, the CAN transceiver operating mode (Active,
Listen-only or Offline) can be selected via bits CMC in the CAN control register (Table 15).
When the UJA1169 is in Standby or Sleep modes, the transceiver is forced to Offline or
Offline Bias mode (depending on bus activity).
7.7.1.1
CAN Active mode
In CAN Active mode, the transceiver can transmit and receive data via CANH and CANL.
The differential receiver converts the analog data on the bus lines into digital data, which
is output on pin RXD. The transmitter converts digital data generated by the CAN
controller (input on pin TXD) into analog signals suitable for transmission over the CANH
and CANL bus lines.
CAN Active mode is selected when CMC = 01 or 10.
When CMC = 01, VCAN undervoltage detection is enabled and the transceiver goes to
CAN Offline or CAN Offline Bias mode when the voltage at the CAN block drops below the
90 % threshold. V1 is monitored for the 90 % threshold in the /X versions; in the V2
versions, the 90 % threshold is related to the V2 supply voltage.
When CMC = 10, VCAN undervoltage detection is disabled. The transmitter remains active
even if the CAN supply falls below the 90 % threshold while V1 is still above the V1 reset
threshold (selected via bits V1RTC).
If pin TXD is held LOW (e.g. by a short-circuit to GND) when CAN Active mode is selected
via bits CMC, the transceiver does not enter CAN Active mode but switches to or remains
in CAN Listen-only mode. In order to prevent a hardware and/or software application
failure from driving the bus lines to an unwanted dominant state, it remains in Listen-only
mode until pin TXD goes HIGH.
In CAN Active mode, the CAN bias voltage is the CAN supply voltage divided by two
(depending on the derivative, the bias voltage is either V1 divided by two or V2 divided by
two).
The application can determine whether the CAN transceiver is ready to transmit/receive
data (CAN supply above 90 % threshold) or is disabled by reading the CAN Transceiver
Status (CTS) bit in the Transceiver Status Register (Table 16).
7.7.1.2
CAN Listen-only mode
CAN Listen-only mode allows the UJA1169 to monitor bus activity while the transceiver is
inactive, without influencing bus levels. The CAN transmitter is disabled in Listen-only
mode, reducing current consumption. The CAN receiver and CAN biasing remain active.
7.7.1.3
CAN Offline and Offline Bias modes
In CAN Offline mode, the transceiver monitors the CAN-bus for a wake-up event, provided
CAN wake-up detection is enabled (CWE = 1; see Table 32). CANH and CANL are biased
to GND.
CAN Offline Bias mode is the same as CAN Offline mode, with the exception that the
CAN-bus is biased to 2.5 V. This mode is activated automatically when activity is detected
on the CAN-bus while the transceiver is in CAN Offline mode. If the CAN-bus is silent (no
CAN-bus edges) for longer than tto(silence), the transceiver returns to CAN Offline mode.

7.7.1.4
CAN Off mode
In CAN Off mode, bus pins CANH and CANL are set floating with respect to GND, which
prevents reverse currents flowing from the bus to an unsupplied ECU. The differential
input resistance between CANH and CANL remains constant.

A filter at the receiver input prevents unwanted wake-up events occurring due to
automotive transients or EMI. A dominant-recessive-dominant wake-up pattern must be
transmitted on the CAN-bus within the wake-up time-out time (tto(wake)) to pass the
wake-up filter and trigger a wake-up event (see Figure 10; note that additional pulses may
occur between the recessive/dominant phases). The recessive and dominant phases
must last at least twake(busrec) and twake(busdom), respectively.

Mini high-speed CAN SBC with optional partial networking
7.8 CAN partial networking (UJA1169 /F variants only)
Partial networking allows nodes in a CAN network to be selectively activated in response
to dedicated wake-up frames (WUF). Only nodes that are functionally required are active
on the bus while the other nodes remain in a low-power mode until needed.
If both CAN wake-up (CWE = 1) and CAN selective wake-up (CPNC = 1) are enabled,
and the partial networking registers are configured correctly (PNCOK = 1), the transceiver
monitors the bus for dedicated CAN wake-up frames.
7.8.1 Wake-up frame (WUF)
A wake-up frame is a CAN frame according to ISO11898-1:2003, consisting of an
identifier field (ID), a Data Length Code (DLC), a data field and a Cyclic Redundancy
Check (CRC) code including the CRC delimiter.
The wake-up frame format, standard (11-bit) or extended (29-bit) identifier, is selected via
bit IDE in the Frame control register (Table 20).
A valid WUF identifier is defined and stored in the ID registers (Table 18). An ID mask can
be defined to allow a group of identifiers to be recognized as valid by an individual node.
The identifier mask is defined in the ID mask registers (Table 19), where a 1 means ‘don’t
care’.
In the example illustrated in Figure 11, based on the standard frame format, the 11-bit
identifier is defined as 0x1A0. The identifier is stored in ID registers 2 (0x29) and 3 (0x2A).
The three least significant bits of the ID mask, bits 2 to 4 of Mask register 2 (0x2D), are
‘don’t care’. This means that any of eight different identifiers will be recognized as valid in
the received WUF (from 0x1A0 to 0x1A7).

Fig 11. Evaluating the ID field in a selective wake-up frame
The data field indicates the nodes to be woken up. Within the data field, groups of nodes
can be predefined and associated with bits in a data mask. By comparing the incoming
data field with the data mask, multiple groups of nodes can be woken up simultaneously
with a single wake-up message.
The data length code (bits DLC in the Frame control register; Table 20) determines the
number of data bytes (between 0 and 8) expected in the data field of a CAN wake-up
frame. If one or more data bytes are expected (DLC 0000), at least one bit in the data

field of the received wake-up frame must be set to 1 and at least one equivalent bit in the
associated data mask register in the transceiver (see Table 21) must also be set to 1 for a
successful wake-up. Each matching pair of 1s indicates a group of nodes to be activated
(since the data field is up to 8 bytes long, up to 64 groups of nodes can be defined). If
DLC = 0, a data field is not expected.
In the example illustrated in Figure 12, the data field consists of a single byte (DLC = 1).
This means that the data field in the incoming wake-up frame is evaluated against data
mask 7 (stored at address 6Fh; see Table 21 and Figure 13). Data mask 7 is defined as
10101000 in the example, indicating that the node is assigned to three groups (Group1,
Group 3 and Group 5).
The received message shown in Figure 12 could, potentially, wake up four groups of
nodes: groups 2, 3, 4 and 5. Two matches are found (groups 3 and 5) when the message
data bits are compared with the configured data mask (DM7).

Fig 12. Evaluating the Data field in a selective wake-up frame
Optionally, the data length code and the data field can be excluded from the evaluation of
the wake-up frame. If bit PNDM = 0, only the identifier field is evaluated to determine if the
frame contains a valid wake-up message. If PNDM = 1 (the default value), the data field is
included for wake-up filtering.
When PNDM = 0, a valid wake-up message is detected and a wake-up event is captured
(and CW is set to 1) when:
• the identifier field in the received wake-up frame matches the pattern in the ID
registers after filtering AND
• the CRC field in the received frame (including a recessive CRC delimiter) was
received without error
When PNDM = 1, a valid wake-up message is detected when:
• the identifier field in the received wake-up frame matches the pattern in the ID
registers after filtering AND
• the frame is not a Remote frame AND
• the data length code in the received message matches the configured data length
code (bits DLC) AND
• if the data length code is greater than 0, at least one bit in the data field of the
received frame is set and the corresponding bit in the associated data mask register is
also set AND
• the CRC field in the received frame (including a recessive CRC delimiter) was
received without error

UJA1169
NXP Semiconductors
Mini high-speed CAN SBC with optional partial networking
If the UJA1169 receives a CAN message containing errors (e.g. a ‘stuffing’ error) that are
transmitted in advance of the ACK field, an internal error counter is incremented. If a CAN
message is received without any errors appearing in front of the ACK field, the counter is
decremented. Data received after the CRC delimiter and before the next Start of Frame
(SOF) is ignored by the partial networking module. If the counter overflows (counter > 31),
a frame detect error is captured (PNFDE = 1) and the device wakes up; the counter is
reset to zero when the bias is switched off and partial networking is re-enabled.
Partial networking is assumed to be configured correctly when PNCOK is set to 1 by the
application software. The UJA1169 clears PNCOK after a write access to any of the CAN
partial networking configuration registers (see Section 7.8.3).
If selective wake-up is disabled (CPNC = 0) or partial networking is not configured
correctly (PNCOK = 0), and the CAN transceiver is in Offline mode with wake-up enabled
(CWE = 1), then any valid wake-up pattern according to ISO 11898-2:201x (upcoming
merged ISO 11898-2/5/6 standard) will trigger a wake-up event.
If the CAN transceiver is not in Offline mode (CMC 00) or CAN wake-up is disabled
(CWE = 0), all wake-up patterns on the bus are ignored.
7.8.2 CAN FD frames
CAN FD stands for ‘CAN with Flexible Data-Rate’. It is based on the CAN protocol as
specified in the upcoming ISO 11898-1:201x standard.
CAN FD is being gradually introduced into automotive market. In time, all CAN controllers
will be required to comply with the new standard (enabling ‘FD-active’ nodes) or at least to
tolerate CAN FD communication (enabling ‘FD-passive’ nodes). The UJA1169TK/F,
UJA1169TK/F/3 and UJA1169TK/X/F support FD-passive features by means of a
dedicated implementation of the partial networking protocol.
The /F variants can be configured to recognize CAN FD frames as valid CAN frames.
When CFDC = 1, the error counter is decremented every time the control field of a CAN
FD frame is received. The UJA1169xx/F remains in low-power mode (CAN FD-passive)
with partial networking enabled. CAN FD frames are never recognized as valid wake-up
frames, even if PNDM = 0 and the frame contains a valid ID. After receiving the control
field of a CAN FD frame, the UJA1169xx/F ignores further bus signals until idle is again
detected.
CAN FD frames are interpreted as frames with errors by the partial networking module
when CFDC = 0. So the error counter is incremented when a CAN FD frame is received. If
the ratio of CAN FD frames to valid CAN frames exceeds the threshold that triggers error
counter overflow, bit PNFDE is set to 1 and the device wakes up.

7.9 CAN fail-safe features
7.9.1 TXD dominant time-out
A TXD dominant time-out timer is started when pin TXD is forced LOW while the
transceiver is in CAN Active Mode. The transmitter is disabled if the LOW state on pin
TXD persists for longer than the TXD dominant time-out time (tto(dom)TXD), releasing the
bus lines to recessive state. The TXD dominant time-out timer is reset when pin TXD goes
HIGH. The TXD dominant time-out time also defines the minimum possible bit rate of
4.4 kbit/s.
When the TXD dominant time-out time is exceeded, a CAN failure event is captured
(CF = 1; see Table 28), if enabled (CFE = 1; see Table 32). In addition, the status of the
TXD dominant time-out can be read via the CFS bit in the Transceiver status register
(Table 16) and bit CTS is cleared.
7.9.2 Pull-up on TXD pin
Pin TXD has an internal pull-up towards V1 to ensure a safe defined recessive driver state
in case the pin is left floating.
7.9.3 VCAN undervoltage event
A CAN failure event is captured (CF = 1), if enabled, when the supply to the CAN
transceiver falls below 90 % of its nominal value. In addition, status bit VCS is set to 1.

7.9.4 Loss of power at pin BAT
When power is lost at pin BAT, the SBC behaves passively towards the CAN-bus pins,
disabling the bias circuitry. This ensures that a loss of power at BAT does not affect
ongoing communication between nodes on the network.
7.10 Wake-up and interrupt event handling
7.10.1 WAKE pin
Local wake-up is enabled via bits WPRE and WPFE in the WAKE pin event capture
enable register (see Table 33). A wake-up event is triggered by a LOW-to-HIGH (if
WPRE = 1) and/or a HIGH-to-LOW (if WPFE = 1) transition on the WAKE pin. This
arrangement allows for maximum flexibility when designing a local wake-up circuit. In
applications that do not use the local wake-up facility, local wake-up should be disabled
and the WAKE pin connected to GND.

While the SBC is in Normal mode, the status of the voltage on pin WAKE can always be
read via bit WPVS. Otherwise, WPVS is only valid if local wake-up is enabled (WPRE = 1
and/or WPFE = 1).
7.10.2 Wake-up diagnosis
Wake-up and interrupt event diagnosis in the UJA1169 is intended to provide the
microcontroller with information on the status of a range of features and functions. This
information is stored in the event status registers (Table 26 to Table 28) and is signaled on
pin RXD, if enabled.
A distinction is made between regular wake-up events and interrupt events.

PO, WDF and PNFDE interrupts are always enabled and thus captured. Wake-up and
interrupt detection can be enabled/disabled for the remaining events individually via the
event capture enable registers (Table 30 to Table 32).
If an event occurs while the associated event capture function is enabled, the relevant
event status bit is set. If the transceiver is in CAN Offline mode with V1 active (SBC
Normal or Standby mode), pin RXD is forced LOW to indicate that a wake-up or interrupt
event has been detected. If the UJA1169 is in sleep mode when the event occurs, the
microcontroller supply, V1, is activated and the SBC switches to Standby mode (via Reset
mode).
The microcontroller can monitor events via the event status registers. An extra status
register, the Global event status register (Table 25), is provided to help speed up software
polling routines. By polling the Global event status register, the microcontroller can quickly
determine the type of event captured (system, supply, transceiver or WAKE pin) and then
query the relevant event status register (Table 26, Table 27, Table 28 or Table 29
respectively).
After the event source has been identified, the status flag should be cleared (set to 0) by
writing 1 to the relevant bit (writing 0 will have no effect). A number of status bits can be
cleared in a single write operation by writing 1 to all relevant bits.
Only clear the status bits that were set to 1 when the status registers were last read. This
precaution ensures that events triggered just before the write access are not lost.
7.10.3 Interrupt/wake-up delay
If interrupt or wake-up events occur very frequently while the transceiver is in CAN Offline
mode, they can have a significant impact on the software processing time (because pin
RXD is repeatedly driven LOW, requiring a response from the microcontroller each time
an interrupt/wake-up is generated). The UJA1169 incorporates an event delay timer to
limit the disturbance to the software.

UJA1169
NXP Semiconductors
Mini high-speed CAN SBC with optional partial networking
When one of the event capture status bits is cleared, pin RXD is released (HIGH) and a
timer is started. If further events occur while the timer is running, the relevant status bits
are set. If one or more events are pending when the timer expires after td(event), pin RXD
goes LOW again to alert the microcontroller. In this way, the microcontroller is interrupted
once to process a number of events rather than several times to process individual
events.
If all events are cleared while the timer is running, RXD remains HIGH after the timer
expires, since there are no pending events. The event capture registers can be read at
any time.
The event capture delay timer is stopped immediately when pin RSTN goes low (triggered
by a HIGH-to-LOW transition on the pin). RSTN is driven LOW when the SBC enters
Reset, Sleep, Overtemp and Off modes. A pending event is signaled on pin RXD when
the SBC enters Sleep mode.
7.10.4 Sleep mode protection
The wake-up event capture function is critical when the UJA1169 is in Sleep mode,
because the SBC only leaves Sleep mode in response to a captured wake-up event. To
avoid potential system deadlocks, the SBC distinguishes between regular and diagnostic
events (see Section 7.10). Wake-up events (via the CAN-bus or the WAKE pin) are
classified as regular events; diagnostic events signal failure/error conditions or state
changes. At least one regular wake-up event must be enabled before the UJA1169 can
switch to Sleep mode. Any attempt to enter Sleep mode while all regular wake-up events
are disabled triggers a system reset.
Another condition that must be satisfied before the UJA1169 can switch to Sleep mode is
that all event status bits must be cleared. If an event is pending when the SBC receives a
Sleep mode command (MC = 001), it immediately switches to Reset mode. This condition
applies to both regular and diagnostic events.
Sleep mode can be permanently disabled in applications where, for safety reasons, the
supply voltage to the host controller must never be cut off. Sleep mode is permanently
disabled by setting the Sleep control bit (SLPC) in the SBC configuration register (see
Table 9) to 1. This register is located in the non-volatile memory area of the device. When
SLPC = 1, a Sleep mode SPI command (MC = 001) triggers an SPI failure event instead
of a transition to Sleep mode.

7.11 Non-volatile SBC configuration
The UJA1169 contains Multiple Time Programmable Non-Volatile (MTPNV) memory cells
that allow some of the default device settings to be reconfigured. The MTPNV memory
address range is from 0x73 to 0x74. For details, see Table 9 and Table 11.
7.11.1 Programming MTPNV cells
NXP delivers the UJA1169 in so-called ‘Forced Normal’ mode, also referred to as the
‘factory preset’ configuration. In order to change the default settings, the device must be in
Forced Normal mode with FNMC = 1 and NVMPS = 1. In Forced Normal mode, the
watchdog is disabled, all regulators are on and the CAN transceiver is in Active mode.

Mini high-speed CAN SBC with optional partial networking
If the device has been programmed previously, the factory presets may need to be
restored before reprogramming can begin (see Section 7.11.2). When the factory presets
have been restored successfully, a system reset is generated automatically and UJA1169
switches back to Forced Normal mode.
Programming of the non-volatile memory (NVM) registers is performed in two steps. First,
the required values are written to addresses 0x73 and 0x74. In the second step,
reprogramming is confirmed by writing the correct CRC value to the MTPNV CRC control
register (see Section 7.11.1.2). The SBC starts reprogramming the MTPNV cells as soon
as the CRC value has been validated. If the CRC value is not correct, reprogramming is
aborted. On completion, a system reset is generated to indicate that the MTPNV cells
have been reprogrammed successfully. Note that the MTPNV cells cannot be read while
they are being reprogrammed.
After an MTPNV programming cycle has been completed, the NVM is protected from
being overwritten.
The MTPNV cells can be reprogrammed a maximum of 200 times (Ncy(W)MTP; see
Table 52). Bit NVMPS in the MTPNV status register (Table 34) indicates whether the
non-volatile cells can be reprogrammed. This register also contains a write counter,
WRCNTS, that is incremented each time the MTPNV cells are reprogrammed (up to a
maximum value of 111111; there is no overflow; performing a factory reset also increments
the counter). This counter is provided for information purposes only; reprogramming will
not be rejected when it reaches its maximum value.
An error correction code status bit, ECCS, is set to indicate the CRC check mechanism in
the SBC has detected and corrected a single bit failure in non-volatile memory. If more
than one bit failure is detected, the SBC will not restart after MTPNV reprogramming.
Check the ECCS flag at the end of the production cycle to verify the content of non-volatile
memory. When this flag is set, it indicates a device or ECU failure.

7.11.2 Restoring factory preset values
Factory preset values are restored if the following conditions apply continuously for at
least td(MTPNV) during battery power-up:
• pin RSTN is held LOW
• CANH is pulled up to VBAT
• CANL is pulled down to GND
After the factory preset values have been restored, the SBC performs a system reset and
enters Forced normal Mode. Since the CAN-bus is clamped dominant, pin RXDC is forced
LOW. Pin RXD is forced HIGH during the factory preset restore process (td(MTPNV)). A
falling edge on RXD caused by bit PO being set after power-on indicates that the factory
preset process has been completed.
Note that the write counter, WRCNTS, in the MTPNV status register is incremented every
time the factory presets are restored.

7.14 General-purpose memory
UJA1169 allocates 4 bytes of memory as general-purpose registers for storing user
information. The general-purpose registers can be accessed via the SPI at address 0x06
to 0x09 without read or write cycle limitations (see Table 39).
7.15 SPI
7.15.1 Introduction
The Serial Peripheral Interface (SPI) provides the communication link with the
microcontroller, supporting multi-slave operations. The SPI is configured for full duplex
data transfer, so status information is returned when new control data is shifted in. The
interface also offers a read-only access option, allowing the application to read back
registers without changing the register content.
The SPI uses four interface signals for synchronization and data transfer:
• SCSN: SPI chip select; active LOW; default level is HIGH (pull-up)
• SCK: SPI clock; default level is LOW due to low-power concept (pull-down)
• SDI: SPI data input (floating input; may need external pull-up or pull-down if not
available in the host controller)
• SDO: SPI data output; floating when pin SCSN is HIGH (may need external pull-up or
pull-down if not available in the host controller)

Fig 15. SPI timing overview (see Figure 19 for detailed SPI timing)
The SPI data in the UJA1169 is stored in a number of dedicated 8-bit registers. Each
register is assigned a unique 7-bit address. Two bytes (16 bits) must be transmitted to the
SBC for a single register read or write operation. The first byte contains the 7-bit address
along with a ‘read-only’ bit (the LSB). The read-only bit must be 0 to indicate a write
operation (if this bit is 1, a read operation is assumed and any data on the SDI pin is
ignored). The second byte contains the data to be written to the register.
24- and 32-bit read and write operations are also supported. The register address is
automatically incremented, once for a 24-bit operation and twice for a 32-bit operation, as
illustrated in Figure 16.

UJA1169
NXP Semiconductors
Mini high-speed CAN SBC with optional partial networking
The contents of the addressed registers are returned via pin SDO during an SPI data read
or write operation,
The UJA1169 tolerates attempts to write to registers that do not exist. If the available
address space is exceeded during a write operation, the data above the valid address
range is ignored (without generating an SPI failure event).
During a write operation, the UJA1169 monitors the number of SPI bits transmitted. If the
number recorded is not 16, 24 or 32, then the write operation is aborted and an SPI failure
event is captured (SPIF = 1).
If more than 32 bits are clocked in on pin SDI during a read operation, the data stream on
SDI is reflected on SDO from bit 33 onwards.
An SPI read/write access must not be attempted for at least tto(SPI) after the UJA1169 exits
Reset mode (positive edge on RSTN). Any earlier access may be ignored (without
generating an SPI failure event).

7.15.3 Register configuration in UJA1169 operating modes
A number of register bits may change state automatically when the UJA1169 switches
from one operating mode to another. This feature is particularly evident when the
UJA1169 switches to Off mode. These changes are summarized in Table 49. If an SPI
transmission is in progress when the UJA1169 changes state, the transmission is ignored
(automatic state changes have priority).

15. Handling information
All input and output pins are protected against ElectroStatic Discharge (ESD) under
normal handling. When handling ensure that the appropriate precautions are taken as
described in JESD625-A or equivalent standards.
16. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
16.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
16.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering

• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities
16.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 24) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 54 and 55

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 24.
