Product details
Overview
R7F100GSN2DFB#HA0 from Renesas is an RL78/G23 128-pin, ultra-low-power 16-bit MCU with 768 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces - deployed in battery-powered industrial HMI and sensor edge nodes.
For engineers reviewing the R7F100GSN2DFB#HA0 datasheet, R7F100GSN2DFB#HA0 pinout, R7F100GSN2DFB#HA0 application, or R7F100GSN2DFB#HA0 equivalent, key selection criteria include its 210-nA data retention current, SNOOZE mode sequencer for autonomous low-power sensing, and LFQFP-128 (0.5 mm pitch) package compatibility with industrial temperature range (−40 to +105°C).
Technical Context
The RL78/G23 core implements a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode), enabling dynamic power/performance scaling. Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation.
Peripheral integration includes ELCL for event-driven logic routing between timers, ADC, and communication units; CTSU2L supporting self- and mutual-capacitance touch with hardware acceleration; and dual independent UARTA modules with LIN-bus compliance. All serial interfaces support background operation during data flash rewriting via BGO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GSL2DFB#HA0 | Same LFQFP-128 package, but 512 KB code flash / 48 KB RAM / −40 to +105°C | Lower code density; suitable where bootloader + application fit in ≤512 KB with identical peripheral set | Select when firmware size is constrained and full 768 KB is unnecessary - reduces cost without sacrificing I/O or temperature rating |
| R7F100GMN2DFB#HA0 | 80-pin LFQFP-80 package, 768 KB flash / 48 KB RAM / same voltage/temp specs | Fewer GPIOs (80 vs. 128 pins), reduced analog channel count (22 vs. 26 ADC inputs), no mutual-capacitance CTSU support | Choose for space-constrained designs where full 128-pin I/O is not required and touch is limited to simple self-cap buttons only |

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GSN2DFB#HA0?
The R7F100GSN2DFB#HA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency and VDD = 3.3 V, typical active current is 41 µA/MHz - resulting in ~1.3 mA total at full speed. This value is measured under standard conditions per R01DS0395EJ0140 Rev.1.40, page 172.
Does the R7F100GSN2DFB#HA0 support hardware-based capacitive touch with mutual capacitance?
Yes, the R7F100GSN2DFB#HA0 integrates the CTSU2L unit supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations. Mutual-capacitance operation requires dedicated TSxx pins (e.g., P30–P31, P70–P73) and is enabled via CTSU2L register settings - confirmed in Section 24.3 of R01DS0395EJ0140.
What debug interface does the R7F100GSN2DFB#HA0 use, and which pins are required?
The R7F100GSN2DFB#HA0 uses the on-chip debugging interface accessible via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P11/P12) pins. These pins support full SWD-style debugging including breakpoint setting, memory inspection, and real-time variable monitoring - detailed in Section 4.3.1 and Table 1-2 of R01DS0395EJ0140.
Can the R7F100GSN2DFB#HA0 perform data flash writes while executing code from program memory?
Yes, the R7F100GSN2DFB#HA0 supports Background Operation (BGO) for data flash. When enabled, the CPU can execute instructions from code flash while the data flash controller rewrites 8 KB of data flash - critical for seamless firmware updates and parameter logging without halting application logic.
What is the pin-compatible upgrade path from the R7F100GSN2DFB#HA0 within the RL78/G23 family?
There is no pin-compatible higher-tier upgrade within the RL78/G23 family - the R7F100GSN2DFB#HA0 is the highest-pin-count (128-pin) variant. For increased performance, designers must migrate to RL78/G24 or RA2 series, which differ in package, pinout, and peripheral architecture. No drop-in replacement exists beyond R7F100GSN2DFB#HA0.
