Product details
Overview
R7F100GPJ3CFB#BA0 from Renesas is a 100-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain support for real-time clock and ultra-low-power SNOOZE mode sequencing - deployed in smart industrial sensors and battery-powered HMI controllers.
For engineers reviewing the R7F100GPJ3CFB#BA0 datasheet, R7F100GPJ3CFB#BA0 pinout, R7F100GPJ3CFB#BA0 application, or R7F100GPJ3CFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, 256 KB flash/24 KB RAM memory configuration, 16-bit TAU timers (16 channels), 12-bit ADC (26 channels), and hardware-accelerated CTSU2L capacitive sensing unit supporting self- and mutual-capacitance modes.
Technical Context
The R7F100GPJ3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its power management includes HALT, STOP, and SNOOZE modes, with the latter enabling autonomous peripheral sequencing without CPU wake-up.
Peripheral integration includes a Logic & Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Remote Control Signal Receiver with 4-pattern waveform matching - all operating under the same low-voltage, wide-temperature envelope as the core.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPJ3CFB#BA0?
The R7F100GPJ3CFB#BA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs; the oscillator maintains ±1.0% accuracy from 1.8 V to 5.5 V and -20 to +85°C.
Does the R7F100GPJ3CFB#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPJ3CFB#BA0 integrates the CTSU2L capacitive touch sensing unit, supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It operates from 1.8–5.5 V and includes hardware noise cancellation, eliminating need for external touch controller ICs.
How many UART, SPI, and I²C interfaces does the R7F100GPJ3CFB#BA0 provide, and are they independently configurable?
The R7F100GPJ3CFB#BA0 provides up to 6 UARTA channels (including LIN support), 8 CSI/SPI channels, and 10 IICA/I²C channels - all independently configurable via peripheral I/O redirection registers (PIOR). Pin multiplexing allows flexible assignment of these interfaces to different physical pins without hardware redesign.
What is the endurance and write/erase capability of the data flash memory in the R7F100GPJ3CFB#BA0?
The R7F100GPJ3CFB#BA0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing CPU code execution from program memory during data flash rewrites - essential for reliable field updates and parameter logging without system interruption.
Is the R7F100GPJ3CFB#BA0 pin-compatible with other RL78/G23 variants, and what package options share the same footprint?
The R7F100GPJ3CFB#BA0 uses a 100-pin LFQFP (0.50-mm pitch) package and is pin-compatible only with other RL78/G23 parts sharing the same FB suffix and pin count (e.g., R7F100GPK3CFB#BA0, R7F100GPL3CFB#BA0). No cross-package compatibility exists with FP (0.80-mm pitch) or NP (HWQFN) variants due to differing land patterns and thermal pad requirements.
