Product details
Overview
R7F100GSJ2DFB#AA0 from Renesas is an RL78/G23 128-pin ultra-low-power 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6 to 5.5 V. It integrates a capacitive touch sensing unit (CTSU2L), 12-bit A/D converter (26 channels), dual D/A converters, RTC, and multiple serial interfaces including UARTA, IICA, and CSI - deployed in industrial human-machine interface and sensor node applications.
For engineers reviewing the R7F100GSJ2DFB#AA0 datasheet, R7F100GSJ2DFB#AA0 pinout, R7F100GSJ2DFB#AA0 application, or R7F100GSJ2DFB#AA0 equivalent, key selection criteria include its 128-pin LFQFP package, -40°C to +85°C temperature grade (D-field), STOP/SNOOZE low-power modes, and CTSU2L support for up to 64-key mutual-capacitance touch panels.
Technical Context
The R7F100GSJ2DFB#AA0 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 SNOOZE mode sequencer executes up to 32 low-power background processes without CPU intervention, using 21 command types for sensor polling and threshold comparison.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, and a Data Transfer Controller (DTC) supporting chain transfers activated by interrupt sources - reducing CPU load during memory-to-peripheral data movement.

The R7F100GSJ2DFB#AA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. This frequency is fully supported across its 1.6–5.5 V supply range and -40°C to +85°C ambient temperature specification.
Does the R7F100GSJ2DFB#AA0 support capacitive touch sensing?
Yes, the R7F100GSJ2DFB#AA0 integrates the CTSU2L capacitive sensing unit, supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations. It operates under VDD = 1.8–5.5 V and includes built-in noise cancellation features for reliable operation in noisy industrial environments.
What debug interface does the R7F100GSJ2DFB#AA0 use?
The R7F100GSJ2DFB#AA0 uses the on-chip debugging interface compatible with Renesas E2 emulator and E2 studio IDE. It supports full JTAG-based debugging, flash programming, and real-time trace via dedicated TOOL0, TOOLRxD, and TOOLTxD pins - no external debug probe required for basic development.
Can the R7F100GSJ2DFB#AA0 operate from a single 3.3 V supply?
Yes, the R7F100GSJ2DFB#AA0 operates reliably from a single 3.3 V supply within its specified 1.6–5.5 V range. All I/O ports are 5 V-tolerant (except controlled-current drive pins), and internal regulators support stable core voltage - enabling direct connection to standard 3.3 V LDOs without level shifting.
What is the data flash endurance rating for the R7F100GSJ2DFB#AA0?
The R7F100GSJ2DFB#AA0 specifies 1,000,000 write/erase cycles (typical) for its 8 KB data flash memory. Background operation (BGO) allows code execution from program memory while rewriting data flash - essential for robust firmware updates and cyclic data logging in field-deployed devices.
Is the R7F100GSJ2DFB#AA0 pin-compatible with other RL78/G23 variants?
The R7F100GSJ2DFB#AA0 shares the same 128-pin LFQFP package and pinout with all RL78/G23 128-pin variants (e.g., R7F100GSK2DFB#AA0, R7F100GSL2DFB#AA0), differing only in flash/RAM size and temperature grade.
