Product details
Overview
R7F100GMK2DFA#BA0 from Renesas is an RL78/G23 80-pin, 384-KB flash, 32-KB RAM ultra-low-power 16-bit MCU operating from 1.6 to 5.5 V, featuring 26-channel 12-bit ADC, capacitive touch sensing (up to 64 keys), and integrated RTC - deployed in battery-powered industrial HMI panels requiring <210-nA data retention current.
For engineers reviewing the R7F100GMK2DFA#BA0 datasheet, R7F100GMK2DFA#BA0 pinout, R7F100GMK2DFA#BA0 application, or R7F100GMK2DFA#BA0 equivalent, key selection criteria include STOP-mode wakeup latency, CTSU2L mutual-capacitance support, 8-channel UARTA with LIN compliance, and LFQFP-80 (0.5-mm pitch) package compatibility with IPC-7351B land patterns.
Technical Context
The R7F100GMK2DFA#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting variable instruction execution time (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode) and hardware multiply/divide/accumulate instructions. Its SNOOZE mode sequencer executes up to 32 low-power processes without CPU, RAM, or flash activation.
It integrates a Logic and Event Link Controller (ELCL) enabling configurable signal routing between peripherals, and supports background data flash rewriting (8 KB, 1M-cycle endurance) while executing code from program memory - critical for field firmware updates in unattended devices.

The R7F100GMK2DFA#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across 1.6 V to 5.5 V VDD. At 32 MHz, minimum instruction execution time is 0.03125 µs; the oscillator maintains ±1.0% accuracy over -40°C to +85°C ambient temperature and 1.8 V to 5.5 V supply range.
Does the R7F100GMK2DFA#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMK2DFA#BA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) modes. It operates at VDD = 1.8 to 5.5 V and includes built-in noise suppression, automatic drift compensation, and programmable scan timing - eliminating need for external touch controller ICs.
How many UARTA channels does the R7F100GMK2DFA#BA0 provide, and do they support LIN bus physical layer compliance?
The R7F100GMK2DFA#BA0 provides six UARTA channels, all supporting LIN 2.2A protocol compliance including break detection, sync field processing, and checksum calculation in hardware. Each UARTA channel can operate independently with configurable baud rates, making it suitable for multi-node LIN clusters such as body electronics or HVAC subsystems.
What is the endurance and retention specification for the data flash memory in the R7F100GMK2DFA#BA0?
The R7F100GMK2DFA#BA0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) with data retention guaranteed for 20 years at +85°C. Background operation (BGO) allows code execution from program memory during data flash rewriting - enabling reliable logging and parameter storage in mission-critical applications.
Can the R7F100GMK2DFA#BA0 enter ultra-low-power STOP mode and wake up via external interrupt or RTC alarm?
Yes, the R7F100GMK2DFA#BA0 supports STOP mode with 210-nA typical current consumption for 4 KB of retained RAM. It wakes up in ≤3.5 µs via external interrupts (INTP0–INTP5), RTC alarm, or dedicated wakeup pins (e.g., P137). The high-speed wakeup capability ensures responsive user interaction while maintaining multi-year battery life in portable devices.
