SANTA CLARA, USA: Renesas Electronics Corp., a premier provider of advanced semiconductor solutions, has announced the development of its new 4th-generation (X4 generation) V850 series of microcontrollers (MCUs) for automotive applications, consisting of four product series: the P-series for chassis and safety applications; D-series for dashboard applications; F-series for body applications; and S-series for car audio systems. Mass production is scheduled to begin in Q2 FY2011.
Renesas Electronics’ 4th-generation MCU series is based on a 90 nanometer (nm) MONOS (metal-oxide-nitride-oxide-silicon) flash technology and uses the 32-bit V850E2 CPU core, which has an excellent performance ratio of 2.5 DMIPS/MHz (Dhrystone MIPS [million instructions per second] per megahertz), and capable of covering a performance range from 48MHz (120MIPS), 80MHz (200MIPS) and up to 160MHz (400MIPS).
Each product series is scalable in memory sizes, peripherals, pin counts and performance, and thereby provides full software and hardware compatibility within each product series. In particular, software re-usability is assured across the four product series by maintaining the same register location for each peripheral.
Fully verified AUTOSAR V3.0/3.1 MCAL software drivers are available for all 4th-generation MCUs. Renesas Electronics’ MCAL software drivers can be obtained as a stand-alone software package or integrated in a complete basic software stack in cooperation with partner companies.
To comply with the AUTOSAR requirements, new system protection functionality (SPF) has been implemented in the new X4-generation MCUs. The SPF includes a memory protection unit (MPU), peripheral register protection unit (PPU), system register protection (SRP) and a timing supervision unit (TSU) that monitors the execution time of the CPU.
