Product details
Overview
R7F100GGK3CFB#BA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain operation for industrial control, sensor nodes, and battery-powered HMI applications.
For engineers reviewing the R7F100GGK3CFB#BA0 datasheet, R7F100GGK3CFB#BA0 pinout, R7F100GGK3CFB#BA0 application, or R7F100GGK3CFB#BA0 equivalent, key selection considerations include its 48-pin LFQFP-0.5 mm pitch package, -40 to +105°C industrial temperature grade, 256 KB flash/24 KB RAM memory configuration, and support for SNOOZE mode sequencer, ELCL event linking, and hardware CRC.
Technical Context
The R7F100GGK3CFB#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) enabling up to 32 low-power autonomous operations without CPU wake-up.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable inter-peripheral signal routing, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) configurations.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GGK3CFB#BA0?
The R7F100GGK3CFB#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply voltage range of 1.6 V to 5.5 V. This allows direct integration with common battery chemistries (e.g., 2×AA, LiSOCl₂) and compatibility with 3.3 V or 5 V system rails without level-shifting circuitry.
Does the R7F100GGK3CFB#BA0 include hardware support for capacitive touch sensing?
Yes, the R7F100GGK3CFB#BA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) configurations. It includes built-in noise suppression, auto-calibration, and hardware-accelerated scan timing - eliminating need for external touch controllers.
What power-saving modes are available on the R7F100GGK3CFB#BA0, and what are their typical current draws?
The R7F100GGK3CFB#BA0 offers HALT (41 µA/MHz), STOP (0.23 µA typical), and SNOOZE modes. In STOP mode with RTC running, current is ~0.5 µA; in deep STOP with RAM retention, it drops to 210 nA. The SNOOZE mode sequencer enables sub-µA background processing - e.g., periodic ADC sampling - without CPU wake-up.
Can the R7F100GGK3CFB#BA0 execute code while rewriting its data flash memory?
Yes, the R7F100GGK3CFB#BA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - essential for reliable firmware parameter storage and field updates without halting application logic.
What is the pin count, package type, and temperature grade of the R7F100GGK3CFB#BA0?
The R7F100GGK3CFB#BA0 uses a 48-pin LFQFP package (7 × 7 mm, 0.50-mm pitch) and is rated for industrial temperature operation from -40°C to +105°C. The "#BA0" suffix indicates tray packaging and "C" field-of-application designation, confirming its suitability for industrial environments.
