A M I S - 3 0 6 6 3 High Speed CAN Transceiver
1.0 General Description
Data Sheet
The AMIS-30663 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus and may be used in both 12V and 24V systems. The digital interface level is powered from a 3.3V supply providing true I/O voltage levels for 3.3V CAN controllers. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode voltage range of the receiver inputs, the AMIS-30663 is able to reach outstanding levels of electromagnetic susceptibility. Similarly, extremely low electromagnetic emission is achieved by the excellent matching of the output signals.

7.0 Functional Description
7.1 General The AMIS-30663 is the interface between the CAN protocol controller and the physical bus. It is intended for use in automotive and industrial applications requiring baud rates up to 1Mbaud. It provides differential transmit capability to the bus and differential receiver capability to the CAN protocol controller. It is fully compatible to the "ISO 11898-2" standard. 7.2 Operating Modes AMIS-30663 only operates in high-speed mode as illustrated in Table 3. The transceiver is able to communicate via the bus lines. The signals are transmitted and received to the CAN controller via the pins TxD and RxD. The slopes on the bus lines outputs are optimised to give extremely low EME.

7.3 Over-temperature Detection A thermal protection circuit protects the IC from damage by switching off the transmitter if the junction temperature exceeds a value of approximately 160C. Because the transmitter dissipates most of the power, the power dissipation and temperature of the IC is reduced. All other IC functions continue to operate. The transmitter off-state resets when pin TxD goes HIGH. The thermal protection circuit is particularly needed when a bus line short circuits. 7.4 TxD Dominant Time-out Function A TxD dominant time-out timer circuit prevents the bus lines from being driven to a permanent dominant state (blocking all network communication) if pin TxD is forced permanently LOW by a hardware and/or software application failure. The timer is triggered by a negative edge on pin TxD. If the duration of the LOW-level on pin TxD exceeds the internal timer value tdom, the transmitter is disabled, driving the bus into a recessive state. The timer is reset by a positive edge on pin TxD. 7.5 Fail-safe Features A current-limiting circuit protects the transmitter output stage from damage caused by accidental short circuit to either positive or negative supply voltage although power dissipation increases during this fault condition. The pins CANH and CANL are protected from automotive electrical transients (according to "ISO 7637"; see Figure 4). Should TxD become disconnected, this pin is pulled high internally. When the VCC supply is removed, pins TxD and RxD will be floating. This prevents the AMIS-30663 from being supplied by the CAN controller through the I/O pins. 7.6 3.3V Interface AMIS-30663 may be used to interface with 3.3V or 5V controllers by use of the V33 pin. This pin may be supplied with 3.3V or 5V to have the corresponding digital interface voltage levels. When the V33 pin is supplied at 2.5V, even interfacing with 2.5V CAN controllers is possible. See also Digital Output Characteristics @ V33 = 2.5V, Table 7. In this case a pull resistor from TxD to V33 is necessary.

10.0 Soldering
10.1 Introduction to Solering Surface Mount Package
Data Sheet
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in the AMIS "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printedcircuit boards with high population densities. In these situations reflow soldering is often used. 10.2 Reflow Soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250C. The top-surface temperature of the packages should preferably be kept below 230C. 10.3 Wave Soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): Larger than or equal to 1.27mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed circuit board; Smaller than 1.27mm, the footprint longitudinal axis must be parallel to the transport direction of the printedcircuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is four seconds at 250C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 10.4 Manual Soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300C. When using a dedicated tool, all other leads can be soldered in one operation within two to five seconds between 270 and 320C.

Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods." 2. These packages are not suitable for wave soldering as a solder joint between the printed circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5mm.
