It can be used to interconnect powerful functions to control and interface car body elec- tronics (lights, wipers, power window, etc.). The TSS463AA is fully compliant with the VAN ISO Standard 11519-3. This standard supports a wide range of applications such as low-cost remote-controlled switches. Typically it is used for lamp control, complex, highly-autonomous, distributed systems, which require fast and secure data transfers. The TSS463AA is a microprocessor-interfaced line controller for mid- to high-com- plexity bus-masters and listeners like dashboard controllers, car stereo or mobile telephone CPUs. The microprocessor interface consists of a 256-byte RAM and a register area divided into 11 control registers, 14 channel register sets and 128 bytes of general purpose RAM, used as a message storage area, and a 6-source maskable interrupt. The circuit operates in the RAM using DMA techniques, controlled by the channel and control registers. This allows virtually any microprocessor, including SPI/SCI interface, to be connected easily to the TSS463AA. Messages are encoded in enhanced Manchester code, and an optional pulsed code for use with an optical or radio link, at a maximum bit rate of 1 Mbit/s. The TSS463AA analyzes the messages received or transmitted according to 6 different criteria includ- ing some higher level checks. In addition, the bus interface has three separate inputs with automatic source diagno- sis and selection. The interface allows for multibus listening or the automatic selection of the most reliable source at any time if several line receivers are connected to the same bus.
