Infineon Technologies' TC1161 and TC1162 microcontrollers (MCUs) have been optimized for demanding embedded applications where real-time control, DSP performance and specific peripheral functions are needed. The 32-bit MCUs are based on the company's TriCore architecture. In addition to a 66MHz CPU, the MCUs integrate 1MB of embedded flash memory and a comprehensive set of peripherals in a low-cost package.

Compared to conventional solutions with separate microcontroller, DSP and PWM ASIC, MCUs can reduce system level costs by up to 40 percent, according to Infineon. Besides the lower system level costs, the TC116x MCUs also contribute to reduced board space, system size and firmware complexity by offering a unified software environment.

The peripheral set includes a flexible timer unit (GPTA) for PWM generation, fast multi-channel ADCs, MultiCAN module (TC1162 only), Asynchronous and Synchronous Serial Interfaces (ASC/SSC) and a Micro Link Interface (MLI) for interfacing to a second controller. The GPTA concept enables scalable motor control solutions and an autonomous full coharent high-speed PWM generation with 0 to 100 percent duty cycle to achieve highly efficient drive operations.

The TC1161 and TC1162 operate at a 1.5V core supply voltage (3.3V I/O) and are available in a low-cost PG-LQFP-176 package for the industrial temperature range from -40C to 85C.

The MCUs have on-chip debugging support for fast development and verification. Software development and debugging tools as well as real time operating systems are available from leading embedded system vendors.

Infineon plans to continuously expand the TC116x product family, introducing four further products in the first half of 2006. The additional members will offer extended memory capacity, higher CPU clock and new peripherals.
