 AUDO MAX family's TC1782

Infineon Technologies AG debuts a family of 32-bit MCUs designed automotive powertrain and chassis applications. The AUDO MAX family supports the design of engine management systems that are compliant with the Euro 5 and Euro 6 emission standards for combustion vehicles. It also enables the electrification of powertrain functions in electrical vehicles.

Key features of the AUDO MAX family are maximum clock frequencies of up to 300MHz, high-speed interfaces like SENT and FlexRay, and comprehensive support for advanced safety engineering by using the PRO-SIL features of the devices. The family is based on TriCore processor architecture and manufactured in 90nm process technology, and is suited for use at temperatures of up to 170C.

For internal combustion engine control applications, AUDO MAX devices are used to calculate the best fuel-air mixture as well as to determine the optimum fuel injection and ignition timing for each cylinder individually. The comprehensive safety features of the AUDO MAX devices support design efforts to deliver higher levels of safety in both powertrain and chassis electronics, such as continuous damping control. Furthermore, AUDO MAX is well-suited for controlling the automatic transmission within an x-by-wire vehicle.

Among the other particular features of the AUDO MAX family are its consequent hardware and software scalability as well as its backward compatibility to its predecessor family AUDO FUTURE, which is already used in many motor control systems of cars today.

For safety-critical systems like electrical power steering, chassis controllers and suspension/damping as well as for specific control units used in hybrid and electrical vehicles, the AUDO MAX family offers the TC179x and TC172x which feature Infineon's PRO-SIL (safety integrity level) functionality.

The AUDO MAX family also offers a scalable approach based on pin compatibility. Automotive system suppliers may upgrade from a smaller to a larger package C e. g. from TC1791, a 200MHz device with 3MB of Flash memory housed in a BGA292 package, to TC1798, a 300MHz device with 4MB of Flash memory packaged in a BGA516. The inner rows of contact bumps are identical for each of these devices, however, with its outer contact bump rows the larger BGAs enable the use of additional I/Os.

The family also includes devices with two 10Mbit/s FlexRay channels and between two and four 1Mbit/s CAN nodes. The world's first Single Edge Nibble Transmission (SENT) interface integrated in a microcontroller simplifies system integration. SENT is an SAE standard for transmission of high resolution sensor data. The built-in interface enables direct communication with digital sensors without the need to insert analog interfaces into the signal chain, which always increase design efforts, board real estate and cost while decreasing accuracy.
