Product details
Overview
R7F100GBG2DFP#BA0 from Renesas is an RL78/G23 32-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, 12-bit ADC (26 channels), and dual 8-bit DACs - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GBG2DFP#BA0 datasheet, R7F100GBG2DFP#BA0 pinout, R7F100GBG2DFP#BA0 application, or R7F100GBG2DFP#BA0 equivalent, key selection criteria include its 32-pin LQFP-0.8mm package, -40°C to +85°C industrial temperature grade, integrated SNOOZE mode sequencer for autonomous low-power operation, and hardware event link controller (ELCL) for peripheral-to-peripheral signal routing without CPU intervention.
Technical Context
The R7F100GBG2DFP#BA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 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 management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs.
Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 configurable commands (e.g., ADC sampling, comparison, timer start/stop) without CPU, RAM, or flash activation; the ELCL enables direct hardware-level event chaining between peripherals like ADC, timers, and communication interfaces.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GBG2DFP#BA0?
The R7F100GBG2DFP#BA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across the full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep functions.
Does the R7F100GBG2DFP#BA0 support hardware debugging, and what interface is used?
Yes, the R7F100GBG2DFP#BA0 supports on-chip debugging via the single-wire debug interface using the TOOL0 (pin 1) and TOOLRxD/TOOLTxD (pins 25/24) signals. This enables full breakpoint, step-through, and memory inspection capabilities without requiring additional debug headers or SWD/JTAG adapters.
How many capacitive touch channels can be implemented using the CTSU2L unit on the R7F100GBG2DFP#BA0?
The CTSU2L unit on the R7F100GBG2DFP#BA0 supports up to 32 self-capacitance keys (one per dedicated pin) or up to 64 mutual-capacitance keys in an 8×8 matrix configuration. Pin assignment is flexible via the peripheral I/O redirection register (PIOR), allowing reuse of analog and digital I/O pins for touch sensing.
What are the key differences between the SNOOZE mode and STOP mode on the R7F100GBG2DFP#BA0?
SNOOZE mode keeps the system clock running and enables autonomous peripheral operation (e.g., ADC sampling, comparisons, timer triggers) via the SNOOZE mode sequencer - all without CPU, RAM, or flash activation. STOP mode halts the main clock entirely and achieves lowest power (0.23 µA typical), waking only on external interrupt or RTC alarm. SNOOZE offers faster wake-up (<1 µs) and richer peripheral activity than STOP.
Can the R7F100GBG2DFP#BA0 perform simultaneous ADC conversions and data flash writes?
Yes - the R7F100GBG2DFP#BA0 supports background operation (BGO) for data flash, allowing full program execution from code flash while rewriting data flash. Combined with the DTC (data transfer controller), ADC conversion results can be automatically transferred to RAM and then written to data flash without CPU intervention, enabling concurrent sensing and non-volatile storage.
