32-bit MCU Utilizes MONOS Memory Structure for Automotive Chassis
The RH850/P1x Series of 32-bit microcontrollers (MCUs) from Renesas combine a 40-nm process with a metal oxide nitride oxide silicon (MONOS) flash memory structure for automotive chassis systems. The MONOS structure facilitates fast data read performance alongside low power consumption, allowing the use of a standard QFP package and a single power supply with integrated core voltage generation regulator. For a high fault-detection rate and short control cycles, the series’ CPU uses a lockstep2 system. An error checking and correcting (ECC) function detects and corrects data errors affecting memory and fault-detection functions allow system-level diagnostics of the timers, ADC, serial communication, and other modules. Two units of Timer S Generation 3 (TSG3) motor control timers are used to improve motor control performance.
