FAQ
What is the maximum operating frequency and performance rating of the R5F100LCAFA#V0?
The R5F100LCAFA#V0 operates up to 32 MHz with a measured performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline CISC architecture and high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C). This performance level supports real-time control loops, sensor fusion, and communication stack processing in resource-constrained applications without external clock sources.
Does the R5F100LCAFA#V0 include an integrated real-time clock (RTC)?
Yes, the R5F100LCAFA#V0 includes a fully featured RTC with calendar function supporting dates up to 99 years, alarm interrupt capability, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz crystal (XT1/XT2) or internal sub-system clock, enabling time-stamped data logging and wake-up scheduling while consuming only 0.57 μA - eliminating the need for external RTC ICs.
How much data flash memory does the R5F100LCAFA#V0 provide, and what is its endurance?
The R5F100LCAFA#V0 provides 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. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - critical for maintaining system responsiveness during firmware updates or parameter storage in the R5F100LCAFA#V0.
What serial communication interfaces are available on the R5F100LCAFA#V0?
The R5F100LCAFA#V0 integrates multiple serial interfaces: up to 4 UART channels (2 with LIN-bus support), 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. Pin multiplexing allows flexible allocation - for example, P10/P11 serve SCK00/SI00/RxD0 - enabling concurrent use of UART, I²C, and SPI in mixed-protocol systems without external bridge ICs.
What is the operating temperature range and voltage specification for the R5F100LCAFA#V0?
The R5F100LCAFA#V0 is rated for industrial operation from -40°C to +85°C (A-grade) with supply voltage ranging from 1.6 V to 5.5 V. This wide voltage range supports direct battery operation (e.g., 2×AA, LiSOCl₂) and compatibility with legacy 5 V logic domains, while the extended temperature capability ensures reliability in enclosed industrial enclosures and automotive cabin environments.
