Product details
Overview
R7F100GSL2DFB#BA0 from Renesas is a 128-pin, ultra-low-power RL78/G23 16-bit MCU with 384 KB code flash, 8 KB data flash, and 32 KB RAM, operating from 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (16 channels), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), targeting industrial HMI and battery-powered sensor nodes.
For engineers reviewing the R7F100GSL2DFB#BA0 datasheet, R7F100GSL2DFB#BA0 pinout, R7F100GSL2DFB#BA0 application, or R7F100GSL2DFB#BA0 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and integrated CTSU2L supporting up to 64 mutual-capacitance keys.
Technical Context
The R7F100GSL2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power architecture includes HALT, STOP, and SNOOZE modes - with 210-nA data retention current for 4 KB RAM and 41-µA/MHz active current - enabling extended battery life in intermittent-sensing applications.
Peripheral integration centers on event-driven autonomy: the Event Link Controller (ELCL) routes signals between peripherals without CPU intervention; the SNOOZE Mode Sequencer (SMS) executes up to 32 preconfigured commands (e.g., ADC sampling, CTSU scan, comparison) while CPU, flash, and RAM remain powered down; and the Data Transfer Controller (DTC) handles background data movement triggered by interrupts.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GSL2DFB#BA0?
The R7F100GSL2DFB#BA0 operates up to 32 MHz using its high-speed on-chip oscillator, delivering a typical active current of 41 µA/MHz at VDD = 3.3 V and TA = 25°C. At 32 MHz, this equates to ~1.31 mA total active current, verified per R01DS0395EJ0140 Rev.1.40 Section 2.3.1. The device maintains ±1.0% accuracy across 1.8–5.5 V and −40°C to +85°C.
Does the R7F100GSL2DFB#BA0 support hardware debugging, and what interface is used?
Yes, the R7F100GSL2DFB#BA0 supports on-chip debugging via the dedicated TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) pins, implementing Renesas' standard E1/E20 debug interface. This enables full JTAG/SW-DP functionality including breakpoint setting, register inspection, and flash programming without requiring additional debug headers or SWD adapters.
How many capacitive touch channels does the R7F100GSL2DFB#BA0 support, and what configurations are available?
The R7F100GSL2DFB#BA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8 × 8 matrix) using dedicated P20–P25 and P60–P62 pins. Configuration is software-selectable via the CTSU2L registers, and all channels operate under VDD = 1.8–5.5 V with built-in noise cancellation.
What serial communication interfaces are included in the R7F100GSL2DFB#BA0, and how many instances of each are available?
The R7F100GSL2DFB#BA0 includes UARTA (6 channels), IICA (10 channels), and CSI (8 channels) - all configurable via peripheral I/O redirection. UARTA supports LIN-bus physical layer compliance; IICA offers master/slave modes with clock stretching; CSI implements SPI-like protocols with programmable polarity/phase. Pin multiplexing allows sharing among interfaces to optimize pin usage.
Is the R7F100GSL2DFB#BA0 pin-compatible with other RL78/G23 variants in the same 128-pin LFQFP package?
Yes, all RL78/G23 devices in the 128-pin LFQFP package (e.g., R7F100GSJ2DFB#BA0, R7F100GSK2DFB#BA0, R7F100GSN2DFB#BA0) share identical pinouts and electrical characteristics per R01DS0395EJ0140 Table 1-1 and Figure 1-1. Memory size, temperature grade, and packaging specification (#BA0) are the only differentiating factors - enabling drop-in replacement for memory or grade upgrades.
