Yes, the R5F101JKDFA#30 includes 8 KB of on-chip data flash memory. It supports 1,000,000 write/erase cycles (typical) and allows background operation (BGO), enabling concurrent program execution and data flash rewriting. Programming voltage range is 1.8 V to 5.5 V, matching the main supply.
What serial communication interfaces are supported by the R5F101JKDFA#30, and which pins support LIN bus functionality?
The R5F101JKDFA#30 supports UART, I²C, and CSI (Simplified SPI). LIN bus functionality is implemented via UART channels-specifically, P11 (RxD0) and P12 (TxD0) support LIN physical layer signaling when configured in UART mode with break-detection and sync-field handling per LIN 2.2A specification.
Is the R5F101JKDFA#30 pin-compatible with other RL78/G13 variants in the same 52-pin LQFP package?
Yes, all RL78/G13 52-pin LQFP variants-including R5F101JKDFA#30, R5F101JLDFA#30, and R5F100JKDFA#30-share identical pinouts and mechanical footprint. Functional differences (e.g., data flash presence, memory size) do not affect pin assignment or electrical characteristics of shared signals.
What development tools and debug interfaces are supported for the R5F101JKDFA#30?
The R5F101JKDFA#30 supports Renesas E2 emulator Lite and E2 studio IDE via SWJ (Serial Wire JTAG) interface using pins P13 (TOOLCLK) and P11/P12 (TOOLRxD/TOOLTxD).
