Product details
Overview
R7F102GBC2DNP#HA0 from Renesas is a 32-pin HWQFN-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 ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, RTC, capacitive touch sensing (up to 29 keys), and multiple serial interfaces - deployed in battery-powered consumer HMI and sensor-edge devices.
For engineers reviewing the R7F102GBC2DNP#HA0 datasheet, R7F102GBC2DNP#HA0 pinout, R7F102GBC2DNP#HA0 application, or R7F102GBC2DNP#HA0 equivalent, this page provides verified package mapping (HWQFN-32, 5×5 mm, 0.50-mm pitch), confirmed pin functions per Renesas R01DS0424EJ0120 Rev.1.20, real-world low-power timing behavior, and validated alternative part selection guidance for industrial-grade embedded designs.
Technical Context
The R7F102GBC2DNP#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It embeds a SNOOZE mode sequencer (SMS) enabling CPU-free periodic processing of up to 32 commands across 21 instruction types - critical for duty-cycled sensor wake-up without RAM/flash activation.
Peripheral integration includes an Event Link Controller (ELC) routing 20 event signals between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and dual I²C/Simplified I²C channels (IICA0/IICA1) plus UARTA (2 channels) and CSI (3 channels) - all mapped to dedicated pins with hardware-level interrupt prioritization and peripheral I/O redirection capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing control for real-time sensor polling and motor commutation. |
| Flash Memory | 32 KB code flash + 2 KB data flash; supports background operation (BGO) for firmware updates without halting execution. |
| Operating Voltage | 1.6–5.5 V; allows direct interface with 1.8 V, 2.5 V, and 3.3 V peripherals without level shifters. |
| Power Modes | HALT (1.2 µA), STOP (200 nA), SNOOZE (1.5 µA typical); enables multi-year battery life in wireless remote controls. |
| ADC Resolution | 10-bit SAR ADC with 10 input channels and internal 1.48 V reference; eliminates need for external voltage reference in temperature/humidity sensing. |
| Capacitive Touch | CTSU2La unit supporting self- and mutual-capacitance methods; enables robust 29-key touchpad implementation on single-layer PCB. |
| Real-Time Clock | RTC with alarm, calendar (1 sec–99 years), and ±1 ppm correction via software; sustains accurate timekeeping during deep sleep. |
Pinout & Package
Package: HWQFN-32, 5 × 5 mm body, 0.50-mm pitch, exposed die pad (recommended to connect to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10 | SCK00/SCL00/TS11 | Primary SPI clock or I²C clock input; also serves as capacitive touch sensor channel 11 - shared function reduces pin count for compact HMI designs. |
| P11 | SI00/RxD0/TOOLRxD/SDA00/TS12 | Multi-function pin for SPI data-in, UART receive, debug RX, I²C data, and touch sense - enables flexible peripheral sharing in resource-constrained layouts. |
| P12 | SO00/TxD0/TOOLTxD/TS13 | Primary SPI data-out, UART transmit, debug TX, and touch sense - supports simultaneous debug visibility and HMI feedback without additional GPIO. |
| P30 | INTP3/TSCAP/RTC1HZ/SCL11/SCK11 | Touch sensor capacitor input, RTC 1-Hz output, and secondary I²C clock - consolidates timing, sensing, and communication on one pin for low-pin-count systems. |
| P31 | TI03/TO03/INTP4/TS01/PCLBUZ0 | Timer input/output, interrupt, touch sense, and programmable buzzer output - enables audible feedback generation directly from timer PWM without external driver. |
| P60 / P61 | SCLA0 / SDAA0 | Dedicated I²C bus lines for secondary I²C interface; isolated from main I²C (P10/P11) to support concurrent sensor and display communication. |
| REGC | Regulator bypass capacitor terminal | Requires 0.47–1 µF capacitor to VSS; stabilizes internal LDO output - omission causes unstable reset behavior and flash corruption. |
| VDD / VSS | Power supply pins | Single 1.6–5.5 V supply; VSS must connect to exposed die pad for thermal and EMI performance in 5×5 mm HWQFN. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 200 nA current draw enables >10-year coin-cell battery life in smart remotes and IoT sensors. |

| Capacitive Touch Unit (CTSU2La) | Supports both self- and mutual-capacitance configurations; achieves <5% noise immunity at 10 V/m EMI without shield layers. |
| Data Flash Background Operation (BGO) | Permits full CPU execution while rewriting 2 KB data flash - essential for secure OTA firmware update logging. |
| Peripheral I/O Redirection (PIOR) | Reassigns up to 12 peripheral functions (e.g., UART, I²C, timers) to alternate pins - resolves routing conflicts in dense 4-layer PCBs. |
| Hardware Event Link Controller (ELC) | Directly links 20 peripheral events (e.g., ADC end-of-conversion → DMA trigger) without CPU intervention - cuts latency to <100 ns. |
