1 Product Description
The TIP810 is an IndustryPack® compatible module with a complete CAN bus interface using the
Philips SJA1000 CAN controller. The Philips SJA1000 CAN controller is a stand-alone controller for
the Controller Area Network (CAN) used within automotive and general industrial environments.
It is the successor of the PCA82C200 CAN controller (Basic CAN) from Philips Semiconductors which
was used on the TIP810-10 V1.0. Additionally, a new mode of operation (PeliCAN) is implemented on
the SJA1000 which supports the CAN 2.0B protocol specification with several new features. The
SJA1000 has the capability to transmit, receive and perform message filtering on standard and
extended messages.
The TIP810 supports a 8 bit bus interface which permits byte accesses to the internal registers of the
SJA1000 controller. The physical interface supports both, CAN high-speed (according to ISO11898)
and modified RS485. Both physical interfaces are optically isolated from the CAN controller. An on
board DC/DC converter supplies the isolated parts of the TIP810.

TIP810 Version 3.0 User Manual Issue 3.0.4 Page 7 of 19
2 Compatibility with TIP810 V1.0, V2.0
The TIP810 V3.0 uses the SJA1000 CAN controller as a replacement of the PCA82C200 CAN
controller which was used on the TIP810 V1.0. The TIP810 V2.0 also had used the SJA1000 CAN
controller, but only in a PCA82C200 compatible way.
The SJA1000 CAN controller on the TIP810 is register-, pin- and function-compatible with the
PCA82C200 if operating in the “BasiCAN" Mode. This mode is the default mode for the SJA1000
CAN controller after power-on.
In the “PeliCAN" Mode the SJA1000 CAN controller supports the full CAN2.0B protocol specification
plus additional features.
Setting the SJA1000 Operation Mode:
The modes can be switched via bit 7 in the Clock Divider Register if the controller is in reset mode.
For a detailed description of the SJA1000 CAN controller, it’s operating modes and additional features
please refer to the SJA1000 data sheet, which is part of the TIP810-ED V3.0 engineering
documentation.

5.3Interrupt Vector Register
The Interrupt Vector Register INTVEC of the TIP810 is a byte wide read/write register located at
address ip_io_base_address + (0x41).
Figure 5-1: Interrupt Vector Register INTVEC
The 8-bit interrupt vector must be loaded by software during initialization of the TIP810.
The Philips SJA1000 CAN controller can generate interrupts on interrupt request line INTREQ0/ of the
IP bus.
Detailed Interrupt Status information can be obtained by read accesses to the Interrupt Register of the
SJA1000 at offset 0x07. Read accesses will reset all interrupt status bits except for the receive
interrupt bit.
Each single interrupt source of the SJA1000 CAN controller can be enabled/disabled in the Interrupt
Enable Register of the SJA1000 at offset 0x09.

6 Programming
6.1Initialization of the Hardware
The Output Control Register of the Philips SJA1000 CAN controller must be programmed for the two
physical interfaces.
Set the SJA1000 Output Control Register (Offset 0x11) to value 0xDA for CAN High Speed and
Modified RS485.
6.2Programming of the SJA1000 Controller
For programming the SJA1000 CAN controller please refer to the SJA1000 data sheet, which is part of
the TIP810-ED engineering documentation.

TIP810 Version 3.0 User Manual Issue 3.0.4 Page 17 of 19
7 Installation
7.1Configuration of the TIP810
The TIP810 must be configured by the jumper field J1 for the desired physical interface:
CAN High Speed Jumper 1 – 3 and 2 – 4 installed.
mod. RS485 Jumper 3 – 5 and 4 – 6 installed.
Figure 7-1: Jumper Configuration
7.2Bus Line Termination
To reduce the stub length of the TIP810 to a minimum, the CAN bus lines for high speed and for mod.
RS485 are connected twice to the IP I/O connector. This means that the CAN bus is routed through
the TIP810.
No termination is provided on board of the TIP810. If the TIP810 is located at one extreme end of the
CAN bus lines then external termination must be provided.
The CAN bus lines must be terminated at both extreme ends of the cable with a resistor,
connected between both CAN bus lines (CAN_H and CAN_L). Resistor value should be equal to
the impedance of the twisted pair (typical 120 ohms).

8 Pin Assignment
8.1Pin Assignment of 50 pin I/O flat cable
The 50-pin flat cable from the IP carrier board will be split into four 9-pin sections. Two sections of the
50 pin flat cable are routed to the CAN High Speed driver and the other two sections are routed to the
modified RS485 driver.
8.1.1 CAN High Speed (Pin 01 - 18) TIP810
The line 1 – 9 fit directly to a 9 pin SUB-D male connector. The assignment of the 9 pin SUB-D
connector meets the suggestion of the CiA (CAN in Automation). Line 1 – 9 is connected on board
with line 10 – 18. With this it is very easy to connect the TIP810 to the CAN bus.
