It operates from 1.6 to 5.5 V and targets industrial HMI, sensor nodes, and battery-powered control systems.
For engineers reviewing the R7F100GGK3CNP#HA0 datasheet, R7F100GGK3CNP#HA0 pinout, R7F100GGK3CNP#HA0 application, or R7F100GGK3CNP#HA0 equivalent, key selection criteria include its 48-pin HWQFN package, -40°C to +105°C industrial temperature grade, 256-KB code flash with 8-KB data flash, SNOOZE mode sequencer for autonomous low-power operation, and CTSU2L capacitive sensing unit supporting up to 64 keys in mutual-capacitance mode.
Technical Context
The R7F100GGK3CNP#HA0 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 power architecture includes HALT, STOP, and SNOOZE modes, achieving 41 µA/MHz active current and 210 nA RAM retention.
Peripheral integration includes a 32-bit interval timer, 16-bit TAU with 16 channels, real-time clock with alarm and correction, 2-channel 8-bit DAC with realtime output, and Logic & Event Link Controller (ELCL) enabling hardware-triggered peripheral chaining without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and low interrupt latency for real-time control. |
| Flash / RAM | 256 KB code flash + 8 KB data flash + 24 KB SRAM; supports background rewriting and secure block protection. |
| Operating Voltage | 1.6–5.5 V; allows direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V peripherals without level shifters. |
| Power Modes | HALT (0.29 µA), STOP (0.34 µA), SNOOZE (1.1 µA); enables sub-µA system sleep with autonomous peripheral sequencing. |
| ADC | 12-bit resolution, 26 input channels, internal 1.48-V reference and temperature sensor; eliminates need for external references in thermal monitoring. |
| Capacitive Sensing | CTSU2L unit supporting self-capacitance (32 keys) or mutual-capacitance (8×8 matrix = 64 keys); enables robust touch UI on single-layer PCBs. |
| Serial Interfaces | UARTA (6 ch), IICA (10 ch), CSI (8 ch); provides flexible multi-protocol connectivity for sensor fusion and host communication. |
Pinout & Package
Package: 48-pin HWQFN (7 × 7 mm, 0.50-mm pitch), exposed die pad (recommended to connect to VSS), industrial-grade (-40°C to +105°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10–P17 | Multi-function I/O with SAU/UARTA/CSI | Primary serial interface bank supporting simultaneous UART, I²C, and SPI functions via peripheral redirection. |
| P20–P25 | Analog input / CTSU / comparator | Shared pins for 12-bit ADC (ANI0–ANI5), capacitive sensing (TSCAP, TS00–TS05), and comparator inputs (IVREF0/1). |
| P30–P31 | RTC / touch / buzzer / interrupt | P30 provides RTC 1-Hz output, TSCAP for CTSU, and INTP3; P31 supports TI03/TO03, INTP4, and PCLBUZ0. |
| P50–P51 | SAU channel 1 I/O | SI11/SDA11 and SO11 support UART/I²C/SPI on SAU1; INTP1/INTP2 enable fast wake-up from low-power modes. |
| P60–P62 | IICA / CTSU / CCD | P60/P61 serve as SCLA0/SDAA0; P62 is dedicated CTSU channel CCD06 - critical for expanding mutual-capacitance matrix size. |
| VDD / VSS / REGC | Power supply / decoupling | REGC requires 0.47–1 µF capacitor to VSS; VDD must be filtered per Renesas layout guidelines to ensure ADC/CTSU accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes up to 32 autonomous processes (e.g., ADC sampling → compare → GPIO toggle) without CPU, flash, or RAM activation - reduces average system power by >90% in polling-based sensing. |
| Background Data Flash Rewrite | Enables firmware updates or parameter storage while executing application code from main flash - no interruption to real-time tasks. |
| ELCL Hardware Event Chaining | Routes signals between peripherals (e.g., TAU overflow → ADC trigger → DMA transfer) in fixed-latency hardware - eliminates software overhead and jitter in time-critical sequences. |
| CTSU2L Mutual-Capacitance Support | Configures 8×8 electrode matrix (64 keys) using only 16 pins; achieves >60 dB noise immunity at 100-Hz scan rate - suitable for wet-hand or EMI-prone industrial panels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLK3CNP#HA0 | 512 KB flash, 48 KB RAM, same 48-pin HWQFN package and peripheral set; identical SNOOZE/CTSU/ELCL features. | Supports larger firmware (e.g., embedded web server, OTA stack) and extended data logging buffers without changing PCB layout. | Select when future firmware growth or enhanced data buffering is anticipated; pin-compatible upgrade path with no hardware revision. |
| STM32L072KBU6 | ARM Cortex-M0+, 128 KB flash, 20 KB RAM, 32-pin QFN; lacks integrated CTSU, ELCL, and SNOOZE sequencer; uses separate touch controller IC. | Requires external components for capacitive touch and event chaining; higher active current (118 µA/MHz) limits battery life in always-on sensing. | Choose only if ARM toolchain ecosystem is mandated; not drop-in - redesign needed for touch, power sequencing, and peripheral interconnect logic. |
Compared with R7F100GLK3CNP#HA0, the R7F100GGK3CNP#HA0 trades flash/RAM capacity for cost-sensitive deployments where firmware fits within 256 KB and 24 KB RAM, while retaining identical low-power architecture and industrial temperature rating.

FAQ
What is the maximum operating temperature range certified for the R7F100GGK3CNP#HA0?
The R7F100GGK3CNP#HA0 is rated for industrial applications with an ambient operating temperature range of -40°C to +105°C, as indicated by the 'C' suffix in its part number and confirmed in the RL78/G23 datasheet Rev.1.40 Section 1.1. This rating applies to the full specified electrical performance, including ADC accuracy, CTSU sensitivity, and flash write endurance.
Does the R7F100GGK3CNP#HA0 support hardware-accelerated capacitive touch sensing without CPU involvement?
Yes, the R7F100GGK3CNP#HA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which operates independently of the CPU. It supports both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) modes, with built-in scan control, noise filtering, and baseline tracking - enabling touch detection during STOP mode with typical current draw of 1.1 µA.
Can the R7F100GGK3CNP#HA0 perform ADC conversions while in low-power STOP mode?
No - ADC conversion requires the CPU or peripheral clock domain to be active. However, the R7F100GGK3CNP#HA0 supports autonomous operation via the SNOOZE Mode Sequencer (SMS), which can trigger ADC sampling, process results, and assert interrupts or GPIOs without waking the CPU core, achieving effective "ADC-in-STOP" behavior with total system current under 2 µA.
What package type and pin count does the R7F100GGK3CNP#HA0 use?
The R7F100GGK3CNP#HA0 uses a 48-pin HWQFN (Heat Sink Quad Flat No-lead) package measuring 7 mm × 7 mm with 0.50-mm pitch and an exposed die pad. This is confirmed by the 'NP' suffix in the part number and documented in Table 1-1 of the RL78/G23 datasheet R01DS0395EJ0140.
How many serial communication interfaces does the R7F100GGK3CNP#HA0 support, and what protocols are included?
The R7F100GGK3CNP#HA0 supports up to 6 UARTA channels (including LIN-bus), 10 IICA channels (I²C-compatible), and 8 CSI channels (SPI-compatible). These are implemented via the Serial Array Unit (SAU) and Serial Interface (SIMP) modules, with flexible pin assignment through the Peripheral I/O Redirection Register (PIOR) - allowing concurrent multi-protocol operation on shared pins.
