Product details
Overview
R7F100GBG2DFP#AA0 from Renesas is a 32-pin RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating at 1.6–5.5 V; features ultra-low power (41 µA/MHz active, 210 nA data retention), capacitive touch sensing (CTSU2L), and integrated peripherals including UART, I²C, SPI, 12-bit ADC (26 channels), and RTC for industrial control and sensor node applications.
For engineers reviewing the R7F100GBG2DFP#AA0 datasheet, R7F100GBG2DFP#AA0 pinout, R7F100GBG2DFP#AA0 application, or R7F100GBG2DFP#AA0 equivalent, key selection criteria include its LQFP-32 package, -40 to +85°C consumer-grade temperature range, 128 KB flash/16 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power operation.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU wake-up, and an Event Link Controller (ELCL) enabling hardware-triggered peripheral coordination.
Peripherals include a 12-bit A/D converter with 26 input channels and internal 1.48 V reference, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and a real-time clock with alarm and correction functions - all designed for deterministic, low-energy embedded control in resource-constrained environments.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GBG2DFP#AA0?
The R7F100GBG2DFP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply voltage range of 1.6 V to 5.5 V. This allows direct interfacing with diverse logic families (1.8 V, 2.5 V, 3.3 V) and enables flexible power design in both battery-powered and line-powered applications. The device maintains full functionality across this entire voltage range.
Does the R7F100GBG2DFP#AA0 include hardware support for capacitive touch sensing?
Yes, the R7F100GBG2DFP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which supports both self-capacitance (up to 32 keys) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It requires no external components beyond standard decoupling capacitors and enables robust touch detection immune to moisture and EMI - a key differentiator for modern HMI designs.
What memory resources are allocated in the R7F100GBG2DFP#AA0?
The R7F100GBG2DFP#AA0 contains 128 KB of code flash memory, 8 KB of data flash memory (rated for 1,000,000 write cycles), and 16 KB of on-chip RAM. The data flash supports background operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash - essential for reliable firmware updates and nonvolatile parameter storage.
Which communication interfaces are available on the R7F100GBG2DFP#AA0?
The R7F100GBG2DFP#AA0 provides multiple serial interfaces: up to 6 UART/UARTA channels (including LIN-bus support), 4–10 I²C/Simplified I²C channels, and 3–8 CSI (SPI-compatible) channels. It also includes a dedicated remote control signal receiver (REMC) for NEC/RC5 protocol decoding - making it suitable for universal remote, sensor hub, and industrial gateway applications.
What low-power modes does the R7F100GBG2DFP#AA0 support, and how do they differ?
The R7F100GBG2DFP#AA0 supports HALT, STOP, and SNOOZE modes. HALT stops the CPU while keeping peripherals active; STOP shuts down most circuitry for 210 nA data retention; SNOOZE mode uses the dedicated sequencer (SMS) to execute up to 32 predefined operations (e.g., ADC sampling, comparison) autonomously - eliminating CPU wake-up and reducing average current in periodic sensing applications.
