Renesas Electronics has expanded its V850 product family of 32-bit high performance microcontrollers (MCU) with the V850E2/PJ4-E featuring an on-chip resolver sensor.
V850E2P Microcontroller Series
The V850E2/PJ4-E minimizes system cost as well as provides higher performance in automotive control systems, such as the motor control system featured in electric vehicles and hybrid electric vehicles. Incorporating the V850E2 CPU core, the P-series RISC MCU is capable of operating in real-time and is equipped with peripheral functions for advanced motor control. The peripheral functions include an A/D converter with sample-and-hold function and a motor control timer that provides a high degree of precision.
The dual core lockstep capability of the P-series combined with the resolver sensor interface makes the V850E2/PJ4-E MCU suitable for a wide range of applications that need to meet the standard requirements of the ISO 26262. The on-chip resolver sensor interface is compatible with several sensors, thus eliminating the necessity of an external converter. For achieving optimal system configuration for motor control, an excitation signal generating function is also featured.
Manufacturers are taking several measures to reduce global warming by making reducing CO2 emissions, whereby electric vehicles and hybrid electric vehicles are being rapidly adopted. To support the environmental performance of these vehicles, it is essential to improve the controlling function of their driving motor. The Renesas V850E2/PJ4-E MCU provides this functionality and also reduces system costs.
Operational in temperatures ranging between 40°C and 125°C, the microcontroller features 1 MB ROM, 80KB RAM and 128MHz CPU frequency.
