General Description
The TH8055 is a physical layer device for a single wire
data link capable of operating with various CSMA/CR
protocols such as the Bosch Controller Area Network
(CAN) version 2.0. This serial data link network is
intended for use in applications where high data rate is
not required and a lower data rate can achieve cost
reductions in both the physical media components and
in the microprocessor and/or dedicated logic devices
which use the network.
The network shall be able to operate in either the
normal data rate mode or a high speed data download
mode for assembly line and service data transfer
operations. The high speed mode is only intended to be
operational when the bus is attached to an off-board service
node. This node shall provide temporary bus electrical loads
which facilitate higher speed operation. Such temporary
loads shall be removed when not performing download
operations.
The bit rate for normal communications is typically 33 kbit/s,
for high speed transmissions like described above a typical
bit rate of 83 kbit/s is recommended. The TH8055 is
designed in accordance to the Single Wire CAN Physical
Layer Specification GMW3089 V1.4 and supports many
additional features like undervoltage lockout , timeout for
faulty blocked input signals, output blanking time in case of
bus ringing and a very low sleep mode current.
