The oscillator accuracy is ±1.0% across −20°C to +85°C and 1.8 V to 5.5 V supply range, eliminating the need for external crystals in many applications. This frequency is fully supported in the R5F100AFASP#30's 30-pin LSSOP package.
Does the R5F100AFASP#30 include an integrated real-time clock (RTC)?
Yes, the R5F100AFASP#30 includes a dedicated real-time clock module with full calendar support (up to 99 years), alarm function, and clock correction capability. It operates independently in STOP mode with only 0.57 μA current draw, powered by the internal low-speed oscillator or an external 32.768 kHz crystal. This RTC is fully functional in the R5F100AFASP#30 and does not require external components for basic timekeeping.
How much data flash memory does the R5F100AFASP#30 provide?
The R5F100AFASP#30 provides 4 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles with background operation (BGO) support. This allows the R5F100AFASP#30 to execute application code from main flash while concurrently rewriting data flash-enabling robust field firmware updates and parameter storage without system interruption.
What communication interfaces are available on the R5F100AFASP#30?
The R5F100AFASP#30 integrates UART/LIN (2 channels), I²C/Simplified I²C (3 channels), and CSI/SPI (2 channels) interfaces-all accessible on its 30-pin LSSOP package. Each UART supports LIN physical layer compliance including automatic sync-break detection and checksum generation, making the R5F100AFASP#30 suitable for automotive body electronics and industrial control networks.
Is the R5F100AFASP#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100AFASP#30 is pin-compatible with all other RL78/G13 devices in the 30-pin LSSOP package (e.g., R5F100BFASP#30, R5F100CFASP#30), sharing identical pin configuration, electrical characteristics, and peripheral mapping.
