FAQ
What is the operating voltage range for the R5F100JKDFA#30?
The R5F100JKDFA#30 operates from 1.6 V to 5.5 V, enabling direct compatibility with common industrial supply rails (3.3 V, 5 V) and battery chemistries including Li-ion, Li-SOCl₂, and alkaline stacks - all while maintaining full peripheral functionality and timing accuracy across the range.
Does the R5F100JKDFA#30 support LIN communication?
Yes, the R5F100JKDFA#30 supports LIN 2.2-compliant communication via its UART peripherals, which include LIN break detection, sync field handling, and checksum calculation - making it suitable for automotive body electronics and industrial sub-networks requiring single-wire deterministic messaging.
What is the maximum ADC sampling rate achievable with the R5F100JKDFA#30?
The R5F100JKDFA#30 achieves up to 1.25 MSPS effective sampling rate using its 10-bit successive approximation ADC with hardware-triggered conversions and automatic channel scanning - sufficient for motor current sensing and fast transient detection in real-time control loops.
How much SRAM is allocated for the flash self-programming library in the R5F100JKDFA#30?
The R5F100JKDFA#30 reserves 2 KB of SRAM starting at address FAF00H for the flash self-programming library - this area is used exclusively for data flash erase/write operations and must be excluded from application variable allocation to prevent corruption during firmware updates.
Is the R5F100JKDFA#30 pin-compatible with other RL78/G13 52-pin variants?
Yes, the R5F100JKDFA#30 shares identical pinout and electrical characteristics with all RL78/G13 52-pin LQFP variants (e.g., R5F100JCDFA#30, R5F101JKDFA#30), enabling drop-in replacement within the same package family - provided firmware accounts for differences in flash size and data flash presence.
