Product details
Overview
R7F100GGG2DNP#AA0 from Renesas is a 48-pin 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 true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit timers, 12-bit ADC (26 channels), and multiple serial interfaces including UART, I²C, and CSI for embedded control in battery-powered consumer devices.
For engineers reviewing the R7F100GGG2DNP#AA0 datasheet, R7F100GGG2DNP#AA0 pinout, R7F100GGG2DNP#AA0 application, or R7F100GGG2DNP#AA0 equivalent, key selection considerations include its HWQFN-48 package, -40°C to +85°C temperature grade (D-suffix), 128 KB flash/16 KB RAM memory configuration, integrated CTSU2L for self/mutual-capacitance touch, and support for SNOOZE mode sequencer for ultra-low-power sensor polling without CPU wake-up.
Technical Context
The R7F100GGG2DNP#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer (SMS) executes up to 32 predefined operations-including ADC sampling, comparator comparison, and timer counting-without CPU, RAM, or flash activation, enabling sub-µA background sensing.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and dual-voltage I/O (1.8/2.5/3.0 V compatible) on select pins. The device supports background data flash rewriting (BGO) with 1M write cycles and flash shield window security.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GGG2DNP#AA0?
The R7F100GGG2DNP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across 1.6–5.5 V supply. It supports three clock domains: high-speed (1–32 MHz), middle-speed (1–4 MHz), and low-speed (32.768 kHz), enabling dynamic voltage/frequency scaling for optimal power efficiency. The R7F100GGG2DNP#AA0 maintains full functionality across its entire 1.6–5.5 V range, including ADC, CTSU2L, and serial interfaces.
Does the R7F100GGG2DNP#AA0 include hardware support for capacitive touch sensing?
Yes, the R7F100GGG2DNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) capable of self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) operation. It includes built-in noise cancellation, automatic drift compensation, and direct hardware linkage to the SNOOZE mode sequencer-allowing touch scanning without CPU intervention. The R7F100GGG2DNP#AA0 requires no external touch controller, reducing BOM cost and board area.
What packaging and thermal specifications apply to the R7F100GGG2DNP#AA0?
The R7F100GGG2DNP#AA0 uses a 48-pin HWQFN package (7 × 7 mm, 0.50-mm pitch) with an exposed die pad recommended for connection to VSS to enhance thermal dissipation. It is rated for ambient operating temperatures from -40°C to +85°C (consumer grade, "D" suffix), with junction temperature limits defined per Renesas' Absolute Maximum Ratings table. The R7F100GGG2DNP#AA0's low active current (41 µA/MHz) minimizes self-heating in compact enclosures.
Can the R7F100GGG2DNP#AA0 perform background data flash writes while executing application code?
Yes, the R7F100GGG2DNP#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors-enabling seamless firmware updates, logging, and parameter storage without system interruption. The R7F100GGG2DNP#AA0 guarantees 1,000,000 write cycles for data flash under typical operating conditions.
How does the SNOOZE mode sequencer (SMS) in the R7F100GGG2DNP#AA0 reduce system power consumption?
The SNOOZE mode sequencer (SMS) in the R7F100GGG2DNP#AA0 executes up to 32 preconfigured steps-including ADC conversions, comparator comparisons, timer counts, and register reads-without waking the CPU, RAM, or flash. This reduces average system current to sub-microamp levels during periodic sensor polling or UI monitoring. Because the R7F100GGG2DNP#AA0 offloads these tasks from software, it achieves >90% power reduction versus CPU-driven polling loops.
