Renesas Electronics RH850/F1x Series 32-bit microcontrollers

The Renesas Electronics RH850/F1x Series of 32-bit microcontrollers (MCUs) for automotive body applications with on-chip flash memory employs a 40 nm process. The on-chip flash memory capacity is from 256 KB up to 8 MB and dual-core versions are also planned for the RH850/F1H Group.

The RH850/F1x Series uses the same architecture CPU core and common peripheral functions and has software compatibility within the same group. It also uses the 40 nm process and metal oxide nitride oxide silicon structure to provide flash memory with lower power consumption (0.5 mA/MHz for RH850/F1L) and higher reliability.

Renesas improved automotive network functions and added a data encryption function for the RH850/F1x Series. These features will help users build electronic body control units combining energy efficiency, high performance and improved safety.

Key features of the RH850/F1x Series MCUs are: a wide array of products for scalability; the CPU core of G3 was designed to achieve lower power consumption and is capable of operating at 80 MHz; it delivers performance of more than 2 DMIPS/MHz while maintaining a low current consumption of 0.5 mA/MHz; it is available in a 48-pin QFP package that is more compact than the earlier Renesas products.

This MCU enables users to achieve high-performance system control with a 32-bit CPU core even in units with limited mounting space. It is suitable for applications such as air-conditioner control or LED headlight control.
