The R5F100FKAFP#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling efficient real-time processing in applications such as motor control and sensor fusion without requiring external acceleration.
Does the R5F100FKAFP#30 support LIN bus communication, and how is it implemented?
Yes, the R5F100FKAFP#30 supports LIN bus communication through its UART peripheral, which includes hardware-level LIN features such as break detection, sync field generation, and checksum calculation. This eliminates software overhead and ensures reliable communication in automotive body electronics and industrial sub-networks.
How much data flash memory does the R5F100FKAFP#30 include, and what is its endurance specification?
The R5F100FKAFP#30 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash while rewriting data flash - essential for logging and field calibration.
What are the low-power operating modes supported by the R5F100FKAFP#30, and what is the lowest achievable current draw?
The R5F100FKAFP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across −40°C to +85°C - making it suitable for decade-long battery operation in utility meters and remote sensors.
Is the R5F100FKAFP#30 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?
Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FAAFP#30, R5F100FKAFP#30, R5F101FKAFP#30) share identical pinouts and mechanical dimensions. Functional differences (e.g., flash size, data flash presence) do not affect PCB layout - enabling scalable firmware development across memory grades.
