Product details
Overview
R7F100GPJ3CFA#BA0 from Renesas is a 100-pin, 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. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich peripherals including 16-bit timers, 12-bit ADC (26 channels), UART/LIN, I²C, and SPI for embedded control in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GPJ3CFA#BA0 datasheet, R7F100GPJ3CFA#BA0 pinout, R7F100GPJ3CFA#BA0 application, or R7F100GPJ3CFA#BA0 equivalent, key selection criteria include its 100-pin LQFP-0.65mm package, -40°C to +105°C temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GPJ3CFA#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including comparisons and calculations-without waking the CPU, flash, or RAM, enabling deterministic low-power periodic sensing.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes event signals between functions (e.g., timer overflow → ADC trigger → DMA transfer), and a Capacitive Touch Sensing Unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual-capacitance (8×8 matrix) operation at VDD = 1.8–5.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ3CFA#BA0 | Same 100-pin LQFP package and industrial temp grade, but 512 KB flash and 48 KB RAM | Targeted at applications requiring larger firmware (e.g., protocol stacks, OTA update partitions) and extended data buffering | Select when firmware size exceeds 256 KB or RAM usage exceeds 24 KB; identical pinout and peripheral set simplify migration |
| R7F100GPJ3CFB#BA0 | Same memory and features, but 100-pin LFQFP (0.50-mm pitch) package instead of LQFP (0.65-mm pitch) | Used where board space is constrained and finer-pitch assembly is available | Choose for higher component density designs; requires PCB layout change due to different footprint and thermal pad requirements |
Compared with R7F100GLJ3CFA#BA0, the R7F100GPJ3CFA#BA0 offers optimized cost and power for mid-complexity industrial control, while R7F100GPJ3CFB#BA0 trades package compatibility for compactness-neither is pin-compatible with the LQFP variant, requiring layout revision.

FAQ
What is the maximum operating frequency of the R7F100GPJ3CFA#BA0?
The R7F100GPJ3CFA#BA0 supports a maximum system clock frequency of 32 MHz using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. External crystal oscillators up to 20 MHz are also supported for applications requiring higher clock accuracy than the ±1% on-chip option.
Does the R7F100GPJ3CFA#BA0 support hardware debugging during development?
Yes, the R7F100GPJ3CFA#BA0 includes full on-chip debugging capability via the single-wire debug interface (SWD), compatible with Renesas E2 studio and CS+ IDEs. It supports breakpoints, watchpoints, real-time variable monitoring, and flash programming without requiring additional debug hardware beyond a standard JTAG/SWD probe.
How many capacitive touch channels does the R7F100GPJ3CFA#BA0 support in mutual-capacitance mode?
The R7F100GPJ3CFA#BA0 supports up to 64 capacitive touch keys in mutual-capacitance mode using an 8×8 electrode matrix configuration. This is implemented through the integrated CTSU2L unit, which operates independently of the CPU and supports automatic noise cancellation and baseline tracking for robust operation in electrically noisy industrial environments.
Can the R7F100GPJ3CFA#BA0 operate from a single 3.3 V supply?
Yes, the R7F100GPJ3CFA#BA0 operates over a wide voltage range of 1.6–5.5 V, making it fully compatible with standard 3.3 V supply rails. All I/O pins are 5 V-tolerant when configured as inputs, and the device supports direct connection to 1.8 V, 2.5 V, and 3.3 V logic families without level shifters.
What is the purpose of the SNOOZE mode sequencer (SMS) in the R7F100GPJ3CFA#BA0?
The SNOOZE mode sequencer (SMS) in the R7F100GPJ3CFA#BA0 executes up to 32 preprogrammed commands-including value comparisons, arithmetic operations, and conditional branching-without waking the CPU, flash, or RAM. This enables autonomous, ultra-low-power periodic tasks like sensor polling or status checking, reducing average system current to sub-microamp levels while maintaining precise timing control.
