How many capacitive touch sensing channels does the R7F100GGG2DFB#AA0 support, and what configurations are available?
The R7F100GGG2DFB#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix). Both modes operate across the full 1.8–5.5 V VDD range, as specified in Section 1.1 "Capacitive sensing unit" of the R01DS0395EJ0140 datasheet.
What are the supported serial communication interfaces on the R7F100GGG2DFB#AA0, and how many instances are available?
The R7F100GGG2DFB#AA0 supports UARTA (3–6 channels), IICA (4–10 channels), and CSI (3–8 channels). For this specific variant (128 KB flash, 48-pin LFQFP), it implements 3 UARTA channels, 4 IICA channels, and 3 CSI channels-peripheral count confirmed in Table 1-2 of the R01DS0395EJ0140 datasheet.
Is the R7F100GGG2DFB#AA0 pin-compatible with other RL78/G23 variants in the same 48-pin LFQFP package?
Yes, all RL78/G23 48-pin LFQFP variants-including R7F100GGG2DFB#AA0, R7F100GGL2DFB#AA0, and R7F100GGH2DFB#AA0-share identical pinouts and electrical characteristics. Memory size and peripheral enablement differ by part number, but PCB layout and signal routing remain fully compatible.
