Product details
Overview
R7F100GGK3CNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 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 control.
For engineers reviewing the R7F100GGK3CNP#AA0 datasheet, R7F100GGK3CNP#AA0 pinout, R7F100GGK3CNP#AA0 application, or R7F100GGK3CNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, 256 KB flash/24 KB RAM memory configuration, C-grade industrial temperature range (−40 to +105°C), and support for SNOOZE mode sequencer-driven autonomous peripheral operation without CPU wake-up.
Technical Context
The R7F100GGK3CNP#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its dual-clock system integrates independent high-speed (±1.0% accuracy), middle-speed, and low-speed on-chip oscillators, allowing dynamic clock switching and STOP-mode wakeup in under 4 µs.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) for autonomous analog/digital processing, an event link controller (ELCL) for hardware-triggered peripheral chaining, and a capacitive sensing unit supporting up to 32 self-capacitance keys or 64 mutual-capacitance keys-both operating at full VDD range (1.8–5.5 V).

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GGK3CNP#AA0?
The R7F100GGK3CNP#AA0 supports up to 32 MHz operation with the high-speed on-chip oscillator, guaranteed across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains functional operation down to 1.6 V, enabling direct use with single-cell Li-ion or multi-cell alkaline batteries without external regulators.
Does the R7F100GGK3CNP#AA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GGK3CNP#AA0 integrates the CTSU2L capacitive sensing unit capable of self-capacitance (up to 32 keys) or mutual-capacitance (8×8 matrix, up to 64 keys) operation. It requires no external RC networks or dedicated touch controller ICs - only electrode layout and firmware configuration. Operation is supported across the full 1.8–5.5 V VDD range with built-in noise suppression.
How many serial communication interfaces does the R7F100GGK3CNP#AA0 provide, and what protocols are supported?
The R7F100GGK3CNP#AA0 provides up to 3 simplified SPI (CSI) channels, 6 UART/UARTA channels (including LIN-bus support), and 10 I²C/Simplified I²C channels. All are implemented in the Serial Array Unit (SAU) and Serial Interface (SIMP) modules. UARTA supports automatic LIN header detection and checksum generation, while I²C includes clock stretching and 10-bit addressing.
What low-power modes are available on the R7F100GGK3CNP#AA0, and what is the wake-up latency from STOP mode?
The R7F100GGK3CNP#AA0 supports HALT, STOP, and SNOOZE modes. From STOP mode, wake-up to full CPU operation takes less than 4 µs when triggered by external interrupt, RTC alarm, or peripheral event. In STOP mode, RAM and register contents are retained at 210 nA, and the 32.768 kHz subsystem clock remains active for RTC and CTSU2L operation.
Is the R7F100GGK3CNP#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 devices in the 48-pin HWQFN package (e.g., R7F100GGF3CNP#AA0 through R7F100GGN3CNP#AA0) share identical pinouts, electrical characteristics, and peripheral mapping. Memory size (96–768 KB flash) and RAM (12–48 KB) vary by part number, but PCB layout, decoupling, and signal routing remain fully interchangeable across the family.
