The RH850/F1x series microcontrollers are successor of V850E2/Fx4 and V850E2/Fx4-L. It expands on-chip flash memory and adds a small 48-pin package. The new microcontrollers are designed for use in a variety of automotive body applications and provide the following advantages:

  1. RH850/F1x Series has three groups; RH850/F1L, RH850/F1M and RH850/F1H.
  2. RH850/F1x Series use the same architecture CPU core, share common peripheral functions and have software compatibility.
  3. 40 nm process and MONOS structure for flash memory with lower power consumption and better reliability
  4. Improved automotive network functions and added data encryption function
