Automotive mcus for electronic control units

Both devices are compliant with ISO 26262 safety standards and employ the 'single core tightly coupled' method. This is optimised to achieve immediate detection of internal system failure and accurately narrow down the location of it. The mcus are said to be suitable for use in the development of fail-operational electronic control systems and be capable of maintaining operation of a vehicle with the minimum functions in the event of failure. The TMPM350FDTFG incorporates Toshiba's original programmable motor driver, excitation signal output circuit for resolvers and a/d converters. The TMPM354F10TFG is designed to control drive motors and incorporates an on-chip resolver to digital converter. This converts signals from the motor resolver to digital data and, according to Toshiba, results in a smaller footprint. The company says it will begin sampling the devices in September this year, with mass production expected to begin in April 2013.
