Automotive mcu has built-in resolver sensor interface

1 min read

Renesas Electronics has announced a new 32bit microcontroller with an on-chip resolver sensor interface, a/d converter and three phase pwm timer.

The V850E2/PJ4-E mcu incorporates Renesas' V850E2 cpu core and is equipped with a set of peripheral functions for motor control. It is said to realise both higher performance and lower system cost for automotive control systems. According to Renesas, the device's on-chip resolver sensor interface corresponds to a range of resolver sensors, eliminating the need for an external resolver-digital converter. An excitation signal generating function for resolver sensor is equipped to offer optimum system configuration for driving motor control. The V850E2/PJ4-E also includes a high precision motor control timer that complies with control of various motors. An a/d converter with synchronised sample and hold function has been implemented to enable more precise measurement of data from each sensor. The new mcu can operate in environments between -40 and 125? and contains a regulator circuit that enables single power supply operation at 5V with an external transistor.
