The RH850/P1L-C was also developed to address ECU miniaturisation and system redundancy needs.
The Group inherits the RH850/P1x-C platform and is said to include many of the embedded safety mechanisms, such as a redundant checker core which operates in lockstep to the master core.
These features enable the RH850/P1L-C devices to support ASIL-D systems and it also incorporates the ICU-S hardware security module, which supports the SHE and EVITA-Light automotive security standards.
The 40nm process used for MCU production is claimed to enable the use of LQFP packages that require no heat sink when using a single power supply and operate at a frequency of 120MHz. These QFP packages use a 0.4mm pin pitch, which results in a more compact ECU. Three pin-count packages are available: 80, 100, and 144 pins.
