Product details

32 MHz RL78 core with 192 KB flash in a 48-LQFP

The R7F100GGH3CFB#BA0 is a 16-bit RL78/G23 MCU clocked at 32 MHz, with 192 KB program flash and 20 KB RAM — enough for a real-time control loop with a capacitive touch HMI and LINbus communication on a single chip. It integrates an 8 KB EEPROM block for parameter storage without external serial memory, and a 10-channel ADC (8/10/12-bit selectable) plus a 2-channel 8-bit DAC for analog sensor interfacing.

Industrial temperature range and wide supply voltage

The supply range spans 1.8 V to 5.5 V, so it runs directly from a 3.6 V Li-ion cell or a 5 V regulated rail without a separate LDO — one less part on the BOM.

Capacitive touch and connectivity peripherals

The on-chip capacitive touch engine supports self-capacitance and mutual-capacitance sensing, eliminating an external touch controller for membrane buttons or slider interfaces. Connectivity includes CSI, I²C, LINbus, SPI, and UART/USART — enough for a LIN slave node in an automotive body module or a sensor hub aggregating I²C peripherals.

Frequently asked questions

What is the difference between R7F100GGH3CFB#BA0 and the R7F100GGH2DFB#BA0 variant?

The H3 also ships in Tape & Reel/Cut Tape, while the H2 comes in Tray packaging.

Can R7F100GGH3CFB#BA0 be used for capacitive touch applications?

Yes, the MCU includes a capacitive touch peripheral (self- and mutual-capacitance) as part of its on-chip peripheral set, so no external touch controller is needed.

What development tools support this MCU?

Renesas provides the e² studio IDE, IAR Embedded Workbench for RL78, and the RL78 Smart Configurator for peripheral code generation. The on-chip debug interface (single-wire) works with the emulator.
