Product details
Overview
R7F100GFN2DFP#AA0 from Renesas is an RL78/G23 44-pin LQFP microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GFN2DFP#AA0 datasheet, R7F100GFN2DFP#AA0 pinout, R7F100GFN2DFP#AA0 application, or R7F100GFN2DFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C consumer-grade temperature range, SNOOZE mode sequencer for autonomous low-power peripheral sequencing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GFN2DFP#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer (SMS) executes up to 32 programmable commands across 21 instruction types-enabling timer-triggered, comparator-based, or CTSU-initiated wakeups while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes signals between peripherals (e.g., ADC completion → DMA trigger → UART transmit start), and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 128+ interrupt sources-including chain transfer for multi-step memory operations without CPU overhead.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GFN2DFP#AA0?
The R7F100GFN2DFP#AA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20°C to +85°C. Operation at 32 MHz is guaranteed down to VDD = 2.7 V; below that, maximum frequency scales per datasheet voltage-frequency curves - e.g., 16 MHz at 1.8 V. The R7F100GFN2DFP#AA0 does not require external crystal for full-speed operation.
Does the R7F100GFN2DFP#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GFN2DFP#AA0 supports on-chip debugging via the single-wire debug interface using the TOOL0 (pin 5) and TOOLRxD/TOOLTxD (pins 25/24) signals. This allows full breakpoint, step-through, and memory inspection capabilities using Renesas E2 studio and E2 Lite emulator. No dedicated JTAG pins are required - the R7F100GFN2DFP#AA0 reuses existing GPIOs for debug, preserving pin count for application use.
How many capacitive touch channels can the R7F100GFN2DFP#AA0 support, and what configurations are available?
The R7F100GFN2DFP#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8 × 8 matrix). Electrode assignment is flexible: any GPIO with TSCAP or TSxx function (e.g., P30, P31, P70–P73, P20–P26) can serve as touch channel. The R7F100GFN2DFP#AA0 includes hardware noise cancellation and auto-calibration - eliminating need for external RC networks or firmware compensation routines.
Can the R7F100GFN2DFP#AA0 perform ADC conversions while in STOP mode, and if not, what low-power alternatives exist?
No, the R7F100GFN2DFP#AA0 cannot perform ADC conversions in STOP mode - the ADC clock is gated during STOP. However, it supports autonomous conversion triggering via the SNOOZE mode sequencer (SMS): the R7F100GFN2DFP#AA0 wakes briefly to execute ADC sampling, process results, and return to STOP - achieving effective 210 nA average current for periodic sensing. SMS also supports comparator-triggered wakeups for threshold-based event detection.
What serial communication interfaces are available on the R7F100GFN2DFP#AA0, and how many instances of each are supported?
The R7F100GFN2DFP#AA0 provides UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - all configurable via peripheral I/O redirection (PIOR). Specifically, it supports 3 UARTA channels (RxD0/TxD0, RxD1/TxD1, RxD2/TxD2), 4 IICA channels (SCLA0/SDAA0, SCLA1/SDAA1, etc.), and 3 CSI channels (SCK00/SI00/SO00, SCK20/SI20/SO20, SCK11/SI11/SO11). All interfaces operate concurrently and support independent baud rates or clock frequencies - the R7F100GFN2DFP#AA0 does not share physical pins across interface types by default.
