Product details
Overview
R7F100GEG3CNP#AA0 from Renesas is a 40-pin HWQFN-packaged 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 ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for industrial sensor nodes and battery-powered HMI interfaces.
For engineers reviewing the R7F100GEG3CNP#AA0 datasheet, R7F100GEG3CNP#AA0 pinout, R7F100GEG3CNP#AA0 application, or R7F100GEG3CNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, industrial temperature range (−40 to +105°C), CTSU2L-based touch interface capability, and support for background data flash rewriting via BGO.
Technical Context
The R7F100GEG3CNP#AA0 implements the RL78 CPU core with a 3-stage pipeline, enabling configurable 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 low-power processes using 21 command types without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Realtime Clock (RTC) with alarm and clock correction-enabling autonomous timekeeping in STOP mode.

FAQ
What is the maximum operating frequency and associated current consumption of the R7F100GEG3CNP#AA0?
The R7F100GEG3CNP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency and VDD = 3.3 V, typical active current is 41 µA per MHz - resulting in ~1.3 mA total at full speed. This value is measured under specified conditions in the R01DS0395EJ0140 datasheet, Section 2.3.
Does the R7F100GEG3CNP#AA0 support hardware-accelerated capacitive touch sensing?
Yes, the R7F100GEG3CNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which performs self-capacitance (up to 32 keys) or mutual capacitance (8×8 matrix) sensing in hardware. No external components are required, and touch processing occurs independently of the CPU during SNOOZE mode - confirmed in Sections 1.1 and 17.1 of the R01DS0395EJ0140 datasheet.
What debug interface does the R7F100GEG3CNP#AA0 use, and what pins are required?
The R7F100GEG3CNP#AA0 uses the on-chip debugging interface accessible via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P11/P12) pins. These pins support Renesas E2 emulator connection for full JTAG-style debugging, flash programming, and real-time trace - detailed in Section 4.3.1 and Table 1-5 of the R01DS0395EJ0140 datasheet.
Can the R7F100GEG3CNP#AA0 perform data flash writes while executing code from program flash?
Yes, the R7F100GEG3CNP#AA0 supports Background Operation (BGO) for data flash. Code execution continues from program flash while data flash is rewritten - enabling safe parameter updates and firmware patching without halting system operation. This is implemented via the Flash Control Unit and documented in Section 13.3 of the R01DS0395EJ0140 datasheet.
What is the purpose of the REGC pin on the R7F100GEG3CNP#AA0, and how must it be connected?
The REGC pin on the R7F100GEG3CNP#AA0 is the bypass capacitor terminal for the internal voltage regulator. It must be connected to VSS via a 0.47 µF to 1 µF ceramic capacitor placed as close as possible to the pin - per Caution note on page 17 of the R01DS0395EJ0140 datasheet. Failure to do so risks unstable core voltage and erratic operation.
