Product details
Overview
R7F100GMN2DFB#AA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 768 KB code flash, 48 KB RAM, and integrated capacitive touch sensing (CTSU2L), operating from 1.6 V to 5.5 V across -40°C to +85°C. It features a 32-MHz RL78 CPU core, 26-channel 12-bit ADC, dual 8-bit DACs, real-time clock, and hardware SNOOZE mode sequencer for autonomous low-power sensor polling in battery-powered HMI and industrial control applications.
For engineers reviewing the R7F100GMN2DFB#AA0 datasheet, R7F100GMN2DFB#AA0 pinout, R7F100GMN2DFB#AA0 application, or R7F100GMN2DFB#AA0 equivalent, this page delivers verified technical context, package-validated pin functions, key design trade-offs versus alternatives, and supply-chain-ready availability details - all grounded in Renesas' official R01DS0395EJ0140 Rev.1.40 specification.
Technical Context
The R7F100GMN2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 autonomous processes using 21 command types without CPU, RAM, or flash activation - enabling sub-µA wake-up-triggered sensor sampling.
Peripheral integration includes a 26-channel 12-bit ADC with internal 1.48-V reference and temperature sensor, dual 8-bit DACs with real-time output, 16 TAU channels, 4–10 I²C/Simplified I²C channels, and ELCL for configurable event-driven peripheral linking - all operating within the same 1.6–5.5 V supply range as the core.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GML2DFB#AA0 | Same 80-pin LFQFP package, but 512 KB flash / 48 KB RAM; identical peripheral set and SNOOZE/CTSU2L features. | Targeted at cost-optimized designs where 768 KB flash headroom is unnecessary; retains full compatibility for firmware porting. | Select when firmware size remains under 450 KB and BOM cost reduction is prioritized over future feature expansion headroom. |

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GMN2DFB#AA0?
The R7F100GMN2DFB#AA0 operates up to 32 MHz with a typical active current of 41 µA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to ~1.31 mA total core current, confirmed in Section 2.3 "Electrical Characteristics" of R01DS0395EJ0140. The device maintains this efficiency across its 1.6–5.5 V supply range.
Does the R7F100GMN2DFB#AA0 support capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMN2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on dedicated pins like P30/P31) and mutual-capacitance (up to 64 keys in 8×8 matrix) modes. Section 1.1 "Features" and Chapter 27 of R01DS0395EJ0140 confirm its operation at VDD = 1.8–5.5 V with built-in noise suppression.
What low-power modes does the R7F100GMN2DFB#AA0 offer, and how does SNOOZE mode differ from STOP mode?
The R7F100GMN2DFB#AA0 provides HALT (0.23 µA), STOP (0.26 µA), and SNOOZE (0.9 µA typical) modes. Unlike STOP - which halts CPU, RAM, and flash - SNOOZE mode keeps the CTSU2L, ADC, and timer peripherals active under sequencer control, enabling autonomous sensor polling without CPU intervention or full wake-up overhead.
Can the R7F100GMN2DFB#AA0 execute code while rewriting its data flash memory?
Yes, the R7F100GMN2DFB#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. As specified in Section 1.1 "Data flash memory", instructions can be fetched and executed from code flash while data flash is being rewritten - enabling uninterrupted real-time operation during parameter updates or firmware patching.
What is the pin-compatible upgrade path from the R7F100GMN2DFB#AA0 within the RL78/G23 family?
The R7F100GMN2DFB#AA0 uses an 80-pin LFQFP (0.50-mm pitch) package shared with other RL78/G23 variants including R7F100GML2DFB#AA0 (512 KB flash) and R7F100GMK2DFB#AA0 (256 KB flash). All share identical pinouts, electrical characteristics, and peripheral mapping - enabling direct PCB reuse when scaling flash/RAM capacity up or down.
