Renesas V850E2/Fx4-L microcontroller series

Renesas has developed the V850E2/Fx4-L series of microcontrollers with 19 new 32-bits.

Designed for the motor vehicle comfort and body segment, the low-power MCUs offer scalability and compatibility combined with peripheral functions to provide solutions for applications such as roof or window lifters, door, seat and light modules, heating, ventilation, and air conditioning and body control modules.

The series enables low current consumption in active mode of less than 0.35 mA at 1 MHz.

The MCUs provide a power-saving feature called the sequencer that supports hardware monitoring of digital inputs in deep stop mode without using the CPU or memory.

When the SEQ detects activities at the digital inputs, the device switches from deep stop mode to run mode. A further feature is the LIN-master controller that supports the automatic LIN-frame detection without CPU interactivity.

The MCUs incorporate a maximum CPU clock from 48 up to 64 MHz with a performance of 1.81 Dhrystone MIPS (DMIPS)/MHz and provides flash memory ranges from 256 KB up to 1.5 MB equipped in packages with pin counts ranging from 64 to 176.

An enhanced peripheral set is implemented, including PWM generation, up to two CAN interfaces as well as eight direct memory access channels.
