Product details
Overview
R7F102G6C3CSP#HA0 from Renesas is a 20-pin LSSOP-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 to 5.5 V. It delivers true low-power operation (37.5 µA/MHz active, 200 nA STOP mode), integrates capacitive touch sensing for up to 29 keys, and supports UART, I²C, and SPI interfaces - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102G6C3CSP#HA0 datasheet, R7F102G6C3CSP#HA0 pinout, R7F102G6C3CSP#HA0 application, or R7F102G6C3CSP#HA0 equivalent, key selection considerations include its 20-pin LSSOP-0.65mm package, -40°C to +85°C industrial temperature grade, CTSU2La-based touch capability, RTC with alarm, and SNOOZE mode sequencer for autonomous low-power event handling.
Technical Context
The R7F102G6C3CSP#HA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power architecture includes HALT, STOP, and SNOOZE modes, with STOP wakeup in under 4 µs and SNOOZE sequencer enabling 32-step autonomous processing without CPU, flash, or RAM activation.
Peripheral integration includes an 8-/10-bit ADC (up to 10 channels), 16-bit timer array (8 channels), RTC with calendar and alarm, watchdog timer, and Event Link Controller (ELC) routing 20 event signals between peripherals. Communication support comprises up to 4 UART/UARTA channels (LIN-capable), 6 I²C/Simplified I²C channels, and 5 CSI (SPI-compatible) channels.

Applications
| Industrial Control Panel | Smart Sensor Node |
|---|---|
Use Scenario: Local HMI on factory equipment with push buttons, sliders, and status LEDs. IC Role / Device Role / Timing Role: Main controller executing touch scan, LED PWM dimming, UART communication with PLC, and RTC-stamped event logging. Use Value: Integrated CTSU2La eliminates external touch IC; 200 nA STOP mode enables multi-year battery life in maintenance-free deployments. |
Use Scenario: Wireless environmental sensor (temp/humidity/pressure) with local display and BLE gateway interface. IC Role / Device Role / Timing Role: Sensor data acquisition (ADC), time-synchronized sampling (RTC + SNOOZE sequencer), and UART-to-BLE bridge logic. Use Value: SNOOZE mode autonomously triggers ADC conversion and data prep every 30 s - CPU remains off >99% of time, extending coin-cell battery life beyond 5 years. |
| Home Appliance Control Board | Energy Meter Interface Module |
Use Scenario: Cooktop or washing machine control with capacitive touch keys and buzzer feedback. IC Role / Device Role / Timing Role: Touch key scanning, PCLBUZ0-driven audio feedback, motor control timing (TAU PWM), and fault monitoring via LVD.

Use Scenario: DIN-rail mounted meter add-on module for pulse counting, tariff switching, and RS-485 communication. IC Role / Device Role / Timing Role: High-accuracy RTC manages time-of-use tariffs; UARTA handles RS-485 Modbus RTU; GPIOs count mechanical meter pulses. Use Value: Calendar RTC maintains correct date/time across power loss; 32 KB flash stores tariff tables and firmware update images locally. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102G6E3CSP#HA0 | 64 KB code flash, same 20-pin LSSOP package, identical peripherals and pinout | Required when firmware exceeds 32 KB or future-proofing for feature expansion is needed | Select if bootloader, crypto stack, or OTA image storage demand >32 KB flash |
| R7F102G4C3CNP#HA0 | 16-pin HWQFN (3×3 mm), 32 KB flash, no P00/P01 or P147 - fewer analog/touch channels and I/O | Suitable for space-constrained, lower-I/O designs where 20-pin footprint is prohibitive | Choose only when board area is critical and 16-pin count satisfies all signal requirements |
Compared with R7F102G6E3CSP#HA0, the R7F102G6C3CSP#HA0 trades flash capacity for cost and code density efficiency; versus R7F102G4C3CNP#HA0, it adds 4 pins, 2 analog inputs, and full touch channel support - enabling richer HMI without redesigning layout or firmware abstraction layers.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F102G6C3CSP#HA0?
The R7F102G6C3CSP#HA0 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 37.5 µA/MHz typical active current. At 32 MHz, this equates to approximately 1.2 mA total core current - verified under VDD = 3.3 V, TA = 25°C per R01DS0424EJ0120 Rev.1.20 Section 1.1. The oscillator accuracy is ±1.0% across 1.8–5.5 V and -20–+85°C.
Does the R7F102G6C3CSP#HA0 support hardware debugging, and what interface is used?
Yes, the R7F102G6C3CSP#HA0 supports full on-chip debugging via the TOOL0 (P40), TOOLRxD (P11), and TOOLTxD (P12) pins using Renesas' E2 or E2 Lite emulator. These pins implement a dedicated 3-wire debug interface compliant with the Renesas FINE specification - enabling breakpoints, watchpoints, register inspection, and flash programming without requiring SWD or JTAG pins.
How many capacitive touch channels can be implemented on the R7F102G6C3CSP#HA0, and what configuration options exist?
The R7F102G6C3CSP#HA0 integrates the CTSU2La unit supporting up to 29 capacitive touch keys. It allows self-capacitance mode (one key per pin, e.g., P20–P22, P147, P00–P01) and mutual-capacitance matrix mode (transmit/receive pin pairs selected from up to 29 pins). Pin assignments are fixed per datasheet Table 1-3; no external components beyond TSCAP (P30) and optional shielding traces are required.
What are the RTC capabilities of the R7F102G6C3CSP#HA0, and does it retain time during STOP mode?
The R7F102G6C3CSP#HA0 features a full-calendar RTC counting seconds to 99 years, with alarm interrupt, periodic interrupt, and clock correction (±0.5 ppm adjustment). It operates from the 32.768 kHz subsystem clock and retains time and alarm settings during STOP mode - confirmed in Section 1.1 and electrical characteristics table of R01DS0424EJ0120 Rev.1.20. RTC1HZ output (P30) is active in STOP.
Is the R7F102G6C3CSP#HA0 pin-compatible with other RL78/G22 variants in the same package?
Yes, the R7F102G6C3CSP#HA0 is fully pin-compatible with all other 20-pin LSSOP RL78/G22 variants (e.g., R7F102G6E3CSP#HA0, R7F102G6C2DSP) - same pin functions, electrical characteristics, and thermal profile. Differences are limited to flash size (32 KB vs. 64 KB) and temperature grade (C-grade industrial -40°C to +85°C), with no impact on PCB layout or schematic design.
