FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GMK2DFB#AA0?
The R7F100GMK2DFB#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator (±1.0% accuracy). At this frequency, its typical active current is 41 µA/MHz, equating to ~1.31 mA total. In STOP mode, it draws only 0.21 µA, and data retention in 32 KB RAM consumes 210 nA-verified per R01DS0395EJ0140 Rev.1.40 Section 1.1.
Does the R7F100GMK2DFB#AA0 support hardware-based cryptographic acceleration?
No, the R7F100GMK2DFB#AA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, RSA engines). Security relies on software libraries executed on the RL78 core. For hardware crypto, consider Renesas RA-family MCUs. The R7F100GMK2DFB#AA0 does provide flash shield window and block erase prohibition for firmware protection.
Can the R7F100GMK2DFB#AA0 drive standard 5 V logic interfaces directly?
No, the R7F100GMK2DFB#AA0 I/O pins are not 5 V tolerant. Its absolute maximum VDD is 5.5 V, but I/O voltage levels are referenced to VDD and rated for 1.8/2.5/3.0 V operation. Driving 5 V logic requires external level-shifting circuitry-confirmed by pin function tables in R01DS0395EJ0140 Sections 1.3.4 and Table 1-5.
How many capacitive touch channels does the R7F100GMK2DFB#AA0 support in mutual-capacitance mode?
The R7F100GMK2DFB#AA0 supports up to 64 capacitive touch keys in mutual-capacitance mode using an 8×8 electrode matrix. This capability is enabled by the integrated CTSU2L unit and confirmed in Section 1.1 "Capacitive sensing unit" of R01DS0395EJ0140 Rev.1.40, which specifies "Mutual capacitance method: Matrix configuration with 8 × 8 pins, supporting up to 64 keys."
Is the R7F100GMK2DFB#AA0 pin-compatible with other RL78/G23 variants in the same 80-pin LFQFP package?
Yes, all RL78/G23 80-pin LFQFP variants-including R7F100GMK2DFB#AA0, R7F100GML2DFB#AA0, and R7F100GMJ2DFB#AA0-share identical pinouts and electrical characteristics. Differences are limited to flash/RAM capacities and factory-programmed security settings, as documented in Table 1-1 and Figure 1-1 of R01DS0395EJ0140 Rev.1.40.
