Product details
Overview
R7F100GFH2DFP#AA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UART, I²C, and CSI for embedded control in battery-powered industrial and consumer devices.
For engineers reviewing the R7F100GFH2DFP#AA0 datasheet, R7F100GFH2DFP#AA0 pinout, R7F100GFH2DFP#AA0 application, or R7F100GFH2DFP#AA0 equivalent, key selection considerations include its 44-pin LQFP-0.8 mm pitch package, -40 to +85°C temperature grade (D-field), integrated SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware event link controller (ELCL) enabling peripheral-to-peripheral signal routing without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-supporting high-speed execution at 32 MHz (0.03125 µs min) or ultra-low-speed operation at 32.768 kHz (30.5 µs min). It includes dedicated multiply/divide/accumulate instructions and a 1 MB address space.
Power management features HALT, STOP, and SNOOZE modes; the latter uses a dedicated sequencer executing up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without waking the CPU, flash, or RAM. Peripheral functions-including TAU timers, RTC, and ELCL-are independently clocked and configurable via register settings.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GFH2DFP#AA0?
The R7F100GFH2DFP#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. This timing assumes use of the high-speed oscillator with no wait states and applies to most basic instructions in the RL78 CISC instruction set.
Does the R7F100GFH2DFP#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GFH2DFP#AA0 supports on-chip debugging via the single-wire debug (SWD) interface using the TOOLRxD (P11) and TOOLTxD (P12) pins. It is compatible with Renesas E2 emulator and standard SWD debuggers, enabling full breakpoint, watchpoint, and memory inspection capabilities without requiring additional debug headers.
How many capacitive touch channels does the R7F100GFH2DFP#AA0 support, and what configurations are available?
The R7F100GFH2DFP#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or up to 64 mutual-capacitance keys (8×8 matrix). Configuration is done via dedicated CTSU registers, and the unit operates independently in SNOOZE mode to minimize power consumption during touch polling.
What are the voltage detector (LVD) thresholds available on the R7F100GFH2DFP#AA0, and how are they configured?
The R7F100GFH2DFP#AA0 includes two independent voltage detectors: LVD0 (selectable thresholds from 1.6 V to 4.2 V in 0.1 V steps) and LVD1 (fixed 2.85 V threshold). Thresholds are configured via the LVD control registers (LVDCR0/LVDCR1), and each can generate interrupts or reset events-enabling flexible brown-out protection and low-battery warning schemes.
Can the R7F100GFH2DFP#AA0 perform ADC conversions while in STOP mode, and if so, how?
No, the R7F100GFH2DFP#AA0 cannot perform ADC conversions in STOP mode because the ADC clock is halted. However, it can execute ADC sampling autonomously in SNOOZE mode using the SNOOZE mode sequencer (SMS), which wakes only the ADC and associated peripherals-achieving ~1.8 µA average current during periodic sensing without full CPU wake-up.
