The leading global advanced semiconductor and solutions suppliers renesas electronics corporation (TSE: 6723, hereinafter referred to as "renesas electronics") today announced the launch of new and low power consumption V850E2 / Fx4-L series 32 bit micro-controller MCU. The new series products are mainly applied in automobile body control, and advanced peripherals combined functions, have scalability and compatibility, and for the roof or Windows nt, door, seat and lighting module, HVAC (heating, ventilation and air conditioning) and carbody control module applied to provide the best solution.

                              Renesas electronics V850E2 / Fx4-L series MCU, mainly used in automobile body control

  Based on V850 new MCU series realized very low power consumption, in the active mode for the power consumption: 0.35 mA / 1 MHz.

  V850E2 / Fx4-L MCU have unique characteristics of energy saving, called sequencing device (SEQ) SEQ support in the province electricity mode for digital input ports of input level monitor change, need not take any CPU or memory. When SEQ in digital input to change detection, the device will switch from an energy saving mode switch to work patterns. There is a unique character LIN is main controller (LMA), not through the CPU interaction, support the automatic detection of LIN framework.
 

  New low power consumption V850E2 / Fx4-L MCU integration and expanded the NEC electronics and renesas technology of the original technology, namely V850 32-bit RISC CPU and energy-saving MONOS (metal oxide nitride oxide silicon) flash technology, the RX and SH series ? MCU 90 nanometres (nm) technology.
 

  V850E2 / Fx4-L MCU adopted from 48 to top 64 MHz CPU module of the biggest MHz, its performance is 1.81 Dhrystone MIPS (DMIPS) / MHz. By the use of the AUTOSAR and enhanced the system function, for larger storage of performance requirements are increasing. V850E2 / Fx4-L MCU through from 256 KB to provide up to 1.5 MB of flash memory meet the needs, these memory using 64 feet to 176 feet from the encapsulation of the lead. Configuration of the enhanced peripherals, including PWM generation, as many as two CAN interface and 8 DMA (DMA) channels.

  After fully the verification of AUTOSAR MCAL (micro controller abstraction layer) software driver package plans to release. Rissa MCAL software driver package can use independent software package or integrated in a and other partners in the cooperative development of complete basic software stack. In order to meet the requirements of the AUTOSAR, has been in V850E2 / Fx4-L all increased in the new device system protection function (SPF). SPF including memory protection unit (MPU) and system registers protection (SRF).

Pricing and availability

  Renesas electronics new V850E2 / Fx4-L MCU samples has been introduced, the price for each $20. Mass production plan started in 2013 and plans to December 2013 volume production scale amounted to 1500000. (price and supply information such as have change without prior notice.

 In the Embedded World 2012 conference on show

  Renesas electronics will be to February 28, 2012 to March 1, 2012 in Berlin, Germany and the Embedded World 2012 conference held on display at the new V850E2 / Fx4-L MCU.
