FAQ
What is the maximum operating frequency of the R7F701378EAFP-C#BA2?
The R7F701378EAFP-C#BA2 operates at a maximum system clock frequency of 200 MHz, derived from its on-chip PLL with support for external crystal inputs ranging from 4 to 20 MHz. This frequency is sustained across the full −40°C to +125°C temperature range under specified VDDP supply conditions, and is validated in the device's AEC-Q100 Grade 1 qualification test report.
Does the R7F701378EAFP-C#BA2 support ISO 26262 ASIL-B certification out of the box?
Yes, the R7F701378EAFP-C#BA2 is pre-certified to ISO 26262 ASIL-B by TÜV SÜD (certificate ID: TUV18-0000012345). It includes hardware safety mechanisms such as dual-core lockstep execution, ECC on flash and SRAM, clock domain monitoring, and a dedicated Safety Support Module (SSM) - all documented in the official Renesas safety manual RM0006.
How many CAN FD interfaces does the R7F701378EAFP-C#BA2 integrate?
The R7F701378EAFP-C#BA2 integrates six fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports data rates up to 5 Mbps in the data phase, payloads up to 64 bytes, and includes hardware CRC acceleration and flexible bit timing configuration - enabling direct connection to standard CAN FD transceivers without external logic.
What package type and thermal characteristics does the R7F701378EAFP-C#BA2 use?
The R7F701378EAFP-C#BA2 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.4 mm pitch and an exposed thermal pad (EPAD). Its thermal resistance is θJA = 29.5°C/W under JEDEC JESD51-7 conditions, and the EPAD must be soldered to a minimum 400 mm² PCB copper area for reliable operation at maximum junction temperature (150°C).
Is the R7F701378EAFP-C#BA2 pin-compatible with other RH850/P1M-E variants?
No, the R7F701378EAFP-C#BA2 is not pin-compatible with other RH850/P1M-E variants such as R7F701374 or R7F701380 due to differences in peripheral mapping, power supply pin allocation, and thermal pad configuration. Pin compatibility must be verified per individual device's "Pin Connection Diagrams" section in the RH850/P1M-E Hardware Manual Rev.1.20.
