FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GFF2DFP#AA0?
The R7F100GFF2DFP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, it draws 41 µA per MHz in active mode, resulting in approximately 1.31 mA total active current. Its STOP mode consumes only 210 nA with 4 KB RAM retention - verified in the R01DS0395EJ0140 datasheet Section 1.1.
Does the R7F100GFF2DFP#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GFF2DFP#AA0 supports on-chip debugging via the dedicated TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and CS+ IDE. These pins implement a 2-wire SWD-like protocol - not full JTAG - and require no external debug header; debug functionality is enabled by default after reset unless disabled in the security settings.
How many capacitive touch channels does the R7F100GFF2DFP#AA0 support, and what configuration options exist?
The R7F100GFF2DFP#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates across the full 1.8–5.5 V supply range and requires no external tuning components - all calibration and noise rejection handled in firmware using Renesas' CTSU middleware library.
Can the R7F100GFF2DFP#AA0 perform ADC conversions while in low-power STOP mode?
No - ADC operation requires the CPU or peripheral clock domain to be active. However, the R7F100GFF2DFP#AA0 supports SNOOZE mode, where the SNOOZE mode sequencer (SMS) can autonomously trigger ADC sampling, process results, and wake the CPU only upon threshold violation - achieving effective "ADC-in-STOP" behavior with 210-nA quiescent current during idle periods.
What is the data flash endurance specification for the R7F100GFF2DFP#AA0, and how is wear leveling managed?
The R7F100GFF2DFP#AA0 specifies 1,000,000 write/erase cycles for its 8 KB data flash memory (typical value per R01DS0395EJ0140 Section 1.1). Wear leveling is not implemented in hardware; it must be handled in application firmware using Renesas' Data Flash Library (DFL), which provides APIs for logical sector abstraction and rotation across physical blocks to extend effective lifetime.
