Product details
Overview
R7F100GGG2DNP#HA0 from Renesas is a 48-pin, consumer-grade RL78/G23 16-bit microcontroller with 96 KB code flash, 8 KB data flash, and 12 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 (up to 64 keys), and rich analog/peripheral integration for battery-powered HMI and sensor-edge applications.
For engineers reviewing the R7F100GGG2DNP#HA0 datasheet, R7F100GGG2DNP#HA0 pinout, R7F100GGG2DNP#HA0 application, or R7F100GGG2DNP#HA0 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official RL78/G23 documentation (R01DS0395EJ0140 Rev.1.40).
Technical Context
The R7F100GGG2DNP#HA0 implements the RL78 CPU core with CISC architecture, 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 supports hardware multiply/divide/accumulate operations and a 1 MB address space.
Its peripheral set includes up to 26-channel 8/10/12-bit ADC with internal 1.48 V reference and temperature sensor, dual 8-bit DACs with real-time output, two comparators with selectable internal/external reference, and a dedicated capacitive sensing unit (CTSU2L) supporting self- and mutual-capacitance modes for robust touch interface design.

|---|---|
|
Use Scenario: Battery-powered IR remote with capacitive touch keys, LED feedback, and low-power wake-on-button press. IC Role / Device Role / Timing Role: Main MCU handling CTSU key scanning, IR modulation (via PCLBUZ0/1), UART communication to host, and STOP-mode wake-up on key interrupt. Use Value: 210 nA data retention and SNOOZE sequencer enable multi-year battery life; integrated CTSU eliminates external touch controller BOM cost. |
Use Scenario: Wearable pulse oximeter collecting analog sensor data (PPG, SpO₂), performing basic signal conditioning, and transmitting via UART to smartphone. IC Role / Device Role / Timing Role: Signal acquisition MCU managing 12-bit ADC sampling, temperature compensation, dual DAC-driven LED drivers, and low-jitter RTC timestamping. Use Value: On-chip 1.48 V reference and temperature sensor enable accurate analog front-end calibration; 41 µA/MHz active current extends wearable runtime per charge. |
| Industrial Panel Meter Interface | White Goods Appliance Control |
|
Use Scenario: Local HMI for industrial meter displaying measured values, accepting user input via touch overlay, and communicating over UART/RS-485. IC Role / Device Role / Timing Role: HMI controller running CTSU for touch overlay, driving segment LCD via SAU, buffering UART data, and managing watchdog safety monitoring. Use Value: 48-pin HWQFN provides sufficient I/O for display, touch, and comms; ELCL enables deterministic event chaining (e.g., ADC → DMA → UART transmit) without CPU load. |
Use Scenario: Embedded control unit in refrigerator or washing machine managing motor drive signals, temperature sensors, user interface LEDs, and buzzer alerts. IC Role / Device Role / Timing Role: System supervisor coordinating PWM motor control (via TAU), 10-bit ADC for thermistor reading, buzzer output (PCLBUZ0/1), and fault-safe STOP-mode entry on overtemperature. Use Value: Integrated 16-bit timer array (TAU) with complementary PWM outputs reduces external gate driver count; HALT/STOP modes cut standby power in always-on appliances. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GGG2DFB#HA0 | Same core, memory, and peripherals; differs only in package - LFQFP (7 × 7 mm, 0.50-mm pitch) instead of HWQFN | Preferred where PCB assembly uses leaded QFP reflow profile or manual inspection is required | Select when mechanical mounting, thermal dissipation via leads, or legacy footprint compatibility is prioritized over board area |
| R7F100GBG2DNP#HA0 | 32-pin HWQFN variant with identical 96 KB/8 KB/12 KB memory but reduced I/O (26 pins vs. 48) and no CTSU2L support | Suitable for simpler sensor nodes or cost-sensitive designs where touch interface is unnecessary | Choose for space-constrained, non-touch applications requiring minimal BOM and lower unit cost - at expense of peripheral scalability |
Compared with R7F100GGG2DNP#HA0, the R7F100GGG2DFB#HA0 offers identical functionality in a more serviceable package, while the R7F100GBG2DNP#HA0 trades I/O count and capacitive sensing for smaller size and lower cost - enabling tiered product variants from a single software base.

Does the R7F100GGG2DNP#HA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GGG2DNP#HA0 integrates the CTSU2L capacitive sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in 8×8 mutual-capacitance matrix mode - ideal for touch sliders, buttons, and proximity detection in consumer and appliance interfaces.
What low-power modes does the R7F100GGG2DNP#HA0 offer, and what are their typical current draws?
The R7F100GGG2DNP#HA0 features HALT, STOP, and SNOOZE modes. Active current is 41 µA/MHz; STOP mode draws 210 nA with 4 KB RAM retention; SNOOZE mode enables peripheral-triggered operations (e.g., ADC, CTSU) without CPU wake-up, achieving sub-µA average current in duty-cycled applications.
Can the R7F100GGG2DNP#HA0 perform background data flash writes while executing code from main flash?
Yes, the R7F100GGG2DNP#HA0 supports Background Operation (BGO) for its 8 KB data flash.
