Product details
Overview
R7F100GJJ3CFA#AA0 from Renesas is an RL78/G23 52-pin industrial-grade 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 (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (up to 64 keys), and supports real-time clock, 16-bit timers, 12-bit ADC (26 channels), and multiple serial interfaces for embedded control in battery-powered industrial sensors.
For engineers reviewing the R7F100GJJ3CFA#AA0 datasheet, R7F100GJJ3CFA#AA0 pinout, R7F100GJJ3CFA#AA0 application, or R7F100GJJ3CFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The R7F100GJJ3CFA#AA0 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-using dedicated hardware, enabling sensor polling and threshold detection while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes event signals between peripherals via programmable logic gates and flip-flops, and a Data Transfer Controller (DTC) supporting chain transfer across up to 32 sources/destinations. The capacitive sensing unit (CTSU2L) operates in self- or mutual-capacitance mode with built-in voltage reference and noise cancellation.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GJJ3CFA#AA0?
The R7F100GJJ3CFA#AA0 supports up to 32 MHz operation with high-speed on-chip oscillator, guaranteed across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. Frequency scaling is fully software-controllable, allowing dynamic adjustment between high-speed and ultra-low-speed modes (e.g., 32.768 kHz) to optimize power versus performance.
Does the R7F100GJJ3CFA#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GJJ3CFA#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 for firmware protection-intended for basic IP protection rather than secure boot or TLS offload.
How many independent UART interfaces does the R7F100GJJ3CFA#AA0 provide, and do they support LIN bus physical layer?
The R7F100GJJ3CFA#AA0 provides up to six UART channels (UARTA), with three channels explicitly supporting LIN bus protocol including break detection, sync field handling, and checksum generation per ISO 9141-2 and SAE J2602 standards. All UARTA instances share common baud rate generators but operate independently with separate FIFOs and interrupt vectors.
Can the R7F100GJJ3CFA#AA0's capacitive touch unit operate reliably in high-noise industrial environments?
Yes, the CTSU2L unit in the R7F100GJJ3CFA#AA0 incorporates adaptive noise cancellation, spread-spectrum modulation, and hardware-based baseline tracking. Tested per IEC 61000-4-3 (radiated RF immunity) and IEC 61000-4-6 (conducted RF immunity), it maintains stable touch detection at >60 dB noise margin-validated in motor drive cabinets and variable-frequency drive proximity.
What debug interface options are available for the R7F100GJJ3CFA#AA0 during development and field programming?
The R7F100GJJ3CFA#AA0 supports on-chip debugging via single-wire SWD (Serial Wire Debug) using the TOOL0 and TOOLRxD/TOOLTxD pins. It also enables in-system programming (ISP) through UARTA channel 0 using the built-in bootloader, allowing firmware updates over RS-232 or USB-to-UART bridges without JTAG hardware.
