Product details
Overview
R7F100GBG3CFP#BA0 from Renesas is a 32-pin LQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +105°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (up to 16 channels), 12-bit ADC (26 channels), dual 8-bit DACs, and UART/I²C/SPI interfaces for low-power embedded control in sensor nodes and industrial HMI.
For engineers reviewing the R7F100GBG3CFP#BA0 datasheet, R7F100GBG3CFP#BA0 pinout, R7F100GBG3CFP#BA0 application, or R7F100GBG3CFP#BA0 equivalent, key selection criteria include its 128-KB flash capacity, 32-pin LQFP-0.8mm package, industrial-grade temperature rating, and integrated CTSU2L for self/mutual capacitance touch sensing without external components.
Technical Context
The RL78/G23 core uses a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/accumulate instructions. Its SNOOZE mode sequencer enables autonomous low-power periodic processing using 32 preloaded commands without CPU wake-up.
Peripheral integration includes an Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and background operation for data flash rewriting while executing program code - all optimized for deterministic real-time response in battery-constrained systems.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GBG3CFP#BA0?
The R7F100GBG3CFP#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains timing specifications over the full industrial temperature range (-40 to +105°C) when powered within this voltage window.
Does the R7F100GBG3CFP#BA0 support hardware debugging, and what interface is used?
Yes, the R7F100GBG3CFP#BA0 supports on-chip debugging via the dedicated TOOL0 and TOOLRxD/TOOLTxD pins, implementing Renesas' E2 emulator interface. This allows full breakpoint, step-through, and memory inspection capabilities without consuming user GPIO or UART resources - critical for industrial firmware validation and field diagnostics.
How many capacitive touch channels does the CTSU2L unit support on the R7F100GBG3CFP#BA0, and what configurations are possible?
The CTSU2L unit on the R7F100GBG3CFP#BA0 supports up to 32 self-capacitance keys using single-pin electrodes or up to 64 mutual-capacitance keys in an 8×8 matrix configuration. All CTSU2L channels operate within the specified VDD = 1.8–5.5 V range and include hardware noise cancellation, eliminating need for external shielding or calibration in most industrial environments.

The R7F100GBG3CFP#BA0 features 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) and guarantees data retention for 20 years at +85°C or 100 years at +25°C. Background operation (BGO) allows code execution from main flash while rewriting data flash - essential for logging, parameter storage, and firmware updates in unattended systems.
Can the R7F100GBG3CFP#BA0 operate from a 1.8-V supply while maintaining full peripheral functionality, including ADC and CTSU2L?
Yes, the R7F100GBG3CFP#BA0 fully supports 1.8-V operation with all peripherals active, including the 12-bit ADC (with internal 1.48-V reference), dual 8-bit DACs (0–VDD output), and CTSU2L (operating range 1.8–5.5 V). This enables direct interfacing with 1.8-V sensors and logic without level shifters, reducing system complexity and power loss in ultra-low-power designs.
