Automotive mcus enable 32bit performance at 8bit cost

Said to enable 32bit performance at 8bit costs, the mcus are targeted at applications such as control modules, low cost airbags and low end engine management designs. Based on a C166SV2 cpu with five stage pipeline, they offer a Multiply Accumulate unit with dsp functionality for dedicated filter algorithms. They are designed to provide an optimised peripheral set for low cost applications with up to two CAN nodes, up to four flexible serial interfaces and up to 19 a/d converter channels. According to Infineon, the 12bit a/d converter provides a conversion time of less than 1µs. An integrated window watch dog with independent clock has been implemented to reduce the demand of external components for automotive applications. Other features include on chip power supply, power control and debug support. The devices are offered with flash capacities of 32, 64, 96 and 160KB. "With 32bit equivalent performance at 8bit prices, the new XC2000 devices complete the industry's most scalable 16bit mcu portfolio," said Peter Schaefer, vp and gm, Microcontrollers, Infineon. "The series addresses the needs of automotive system suppliers from emerging markets to luxury class."
