Renesas Electronics unveils 19 new 32bit mcus

Designed for the automotive comfort and body market, the low power mcus are designed to automotive body solutions for applications such as roof or window lifters, door, seat and light modules and body control modules. According to the semiconductor specialist, the V850-based mcu series enables very low current consumption in active mode of less than 0.35mA at 1MHz. The V850E2/Fx4-L mcus incorporate a unique power saving feature called the sequencer (SEQ). The SEQ supports hardware monitoring of digital inputs in deep stop mode without any usage of the cpu or memory. When it detects activities at the digital inputs, the device switches from deep stop mode to run mode. An additional unique feature is the LIN master controller which supports the automatic LIN frame detection without cpu interactivity. The devices incorporate a maximum cpu clock from 48 up to 64MHz with a performance of 1.81 Dhrystone MIPS (DMIPS)/MHz. With the adoption of AUTOSAR and increased system functionality, there is growing demand for larger memory capacity. Renesas claims to have addressed this demand by providing flash memory ranges from 256KB up to 1.5MB 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 8 direct memory access channels. Samples of Renesas' new V850E2/Fx4-L mcus are available now with mass production scheduled to begin in the beginning of 2013.
