Product details
Overview
R7F100GPJ3CFA#AA0 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 dual 16-bit timer arrays - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPJ3CFA#AA0 datasheet, R7F100GPJ3CFA#AA0 pinout, R7F100GPJ3CFA#AA0 application, or R7F100GPJ3CFA#AA0 equivalent, key selection considerations include its LQFP-100 package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power operation, and hardware-accelerated CTSU2L capacitive sensing unit.
Technical Context
The R7F100GPJ3CFA#AA0 implements the RL78 CPU core with a 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 preconfigured commands-including ADC sampling, comparator evaluation, and GPIO toggling-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Realtime Clock with alarm and correction functions. The device supports background data flash rewriting (BGO) and on-chip debugging via SWD interface.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPJ3CFA#AA0?
The R7F100GPJ3CFA#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. Frequency scaling is supported down to 32.768 kHz for ultra-low-power RTC operation, maintaining full peripheral functionality including ADC and CTSU2L at all speeds.
Does the R7F100GPJ3CFA#AA0 support hardware-accelerated cryptographic operations?
No, the R7F100GPJ3CFA#AA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption tasks. Security features are limited to flash memory block erase/write prohibition and boot swapping with flash shield window-intended for IP protection rather than runtime crypto acceleration.
How many capacitive touch channels can the R7F100GPJ3CFA#AA0 support in mutual-capacitance mode?
The R7F100GPJ3CFA#AA0 supports up to 64 capacitive touch keys in mutual-capacitance mode using an 8×8 electrode matrix. This capability is delivered by the CTSU2L unit, which requires dedicated CCDx pins (e.g., P60–P62, P16–P17, P50–P51) configured as either transmit or receive channels-enabling robust touch detection even in noisy industrial environments.
What debug interface does the R7F100GPJ3CFA#AA0 use, and what pins are required?
The R7F100GPJ3CFA#AA0 uses the Serial Wire Debug (SWD) interface, requiring only two pins: SWDIO (shared with P10) and SWCLK (shared with P11). No dedicated debug port is needed-the interface operates alongside normal GPIO and serial functions, enabling in-circuit debugging and programming without sacrificing I/O resources or requiring additional connectors.
Is the R7F100GPJ3CFA#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 devices in the 100-pin LQFP package (e.g., R7F100GLJ3CFA#AA0, R7F100GMJ3CFA#AA0) share identical pinouts, electrical characteristics, and peripheral mappings. Differences are limited to memory sizes and factory-programmed options-allowing drop-in replacement for memory upgrades without PCB revision or firmware rework beyond linker script adjustments.
