Product details
Overview
R7F100GBH2DFP#BA0 from Renesas is an RL78/G23 32-bit ultra-low-power MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It features a 32-MHz high-accuracy on-chip oscillator (±1.0%), 16-bit timer array (16 channels), 12-bit A/D converter (26 channels), capacitive touch sensing (up to 64 keys), and integrated UART/I²C/SPI interfaces - deployed in battery-powered industrial sensor nodes requiring sub-100 µA active current and 210-nA data retention.
For engineers reviewing the R7F100GBH2DFP#BA0 datasheet, R7F100GBH2DFP#BA0 pinout, R7F100GBH2DFP#BA0 application, or R7F100GBH2DFP#BA0 equivalent, this page delivers verified electrical specs, validated LQFP-32 package mapping, confirmed SNOOZE mode sequencer operation, and real-world use cases for energy-constrained embedded control.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz or 30.5 µs at 32.768 kHz), supporting multiply/divide/accumulate operations and 1 MB address space. Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling autonomous peripheral sequencing (32-step, 21 command types) without CPU, RAM, or flash activation.
Peripheral integration includes a Logic & Event Link Controller (ELCL) for hardware-triggered signal routing between modules, a Data Transfer Controller (DTC) with chain transfer support, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain and controlled-current drive options - all optimized for deterministic low-energy operation in noisy industrial environments.

Background operation (BGO) allows code execution from flash while rewriting data flash - a core capability of the R7F100GBH2DFP#BA0.
How many capacitive touch channels does the R7F100GBH2DFP#BA0 support, and what configurations are available?
The R7F100GBH2DFP#BA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix).

The R7F100GBH2DFP#BA0 provides up to 6 UART/LIN channels, 10 I²C channels, and 8 SPI channels - all multiplexed on P10–P17, P50–P51, P60–P62, and P70–P73. Pin functions are configurable via the Peripheral I/O Redirection Register (PIOR), allowing dynamic assignment of SAU, IICA, or UARTA to specific pins. This flexibility is inherent to the R7F100GBH2DFP#BA0's LQFP-32 pinout.
What power modes does the R7F100GBH2DFP#BA0 support, and what are their typical current draws?
The R7F100GBH2DFP#BA0 supports HALT (core stopped, peripherals active), STOP (all clocks halted except RTC), and SNOOZE (peripheral-only autonomous operation) modes. Typical currents are 41 µA/MHz in active mode, 210 nA in STOP with 4 KB RAM retention, and <1 µA in SNOOZE with CTSU2L or ADC active. These values are measured and specified for the R7F100GBH2DFP#BA0 under industrial conditions.
