Product details
Overview
R7F102G7C2DNP#BA0 from Renesas is a 24-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6–5.5 V. It delivers true low-power operation (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, up to 29 capacitive touch sensors, RTC, and multiple serial interfaces including UARTA, IICA, and CSI-targeting battery-powered consumer HMI and sensor-edge applications.
For engineers reviewing the R7F102G7C2DNP#BA0 datasheet, R7F102G7C2DNP#BA0 pinout, R7F102G7C2DNP#BA0 application, or R7F102G7C2DNP#BA0 equivalent, key selection considerations include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) footprint, 32 KB flash/4 KB RAM memory configuration, -40°C to +85°C industrial-grade temperature range, and integrated CTSU2La capacitive sensing unit supporting self- and mutual-capacitance topologies.
Technical Context
The RL78/G22 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode), enabling dynamic power/performance trade-offs. It supports multiply/divide/MAC instructions and features a 1 MB address space with four banks of eight 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes-with STOP wakeup in under 4 µs-and dual voltage detectors (LVD0/LVD1). The SNOOZE Mode Sequencer (SMS) executes up to 32 preconfigured operations (from 21 command types) without CPU, flash, or RAM involvement, reducing active current during periodic sensing tasks.

What debug interface does R7F102G7C2DNP#BA0 use, and how is it accessed?
R7F102G7C2DNP#BA0 uses Renesas' on-chip debugging interface accessible via TOOLRxD (P11), TOOLTxD (P12), and TOOL0 (P40) pins. These share functions with UARTA and GPIO, requiring no dedicated debug header - simplifying PCB layout and enabling in-system programming through standard UART connections.
Can R7F102G7C2DNP#BA0 execute code while writing to data flash memory?
Yes, R7F102G7C2DNP#BA0 supports Background Operation (BGO) for its 2 KB data flash.
