Product details
Overview
R7F100GJG2DFA#AA0 from Renesas is a 52-pin, consumer-grade RL78/G23 16-bit microcontroller 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 (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GJG2DFA#AA0 datasheet, R7F100GJG2DFA#AA0 pinout, R7F100GJG2DFA#AA0 application, or R7F100GJG2DFA#AA0 equivalent, key selection criteria include its 52-pin LFQFP-0.65mm package, 256 KB flash/24 KB RAM memory configuration, CTSU2L-based touch channel count (up to 64 keys in mutual mode), RTC with alarm and correction, and support for SNOOZE mode sequencer for autonomous low-power peripheral sequencing without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz, 30.5 µs at 32.768 kHz), multiply/divide/accumulate instructions, and 1 MB address space. It integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential operations using 21 command types-enabling autonomous analog measurement, comparison, and I/O control while the CPU, flash, and RAM remain powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware event routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a flexible serial interface suite: up to 10 I²C/Simplified I²C channels, 6 UART/UARTA (LIN-capable) channels, and 8 CSI (SPI-compatible) channels-all configurable via peripheral I/O redirection registers (PIOR) without PCB changes.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GJG2DFA#AA0?
The R7F100GJG2DFA#AA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and low-power monitoring tasks, maintaining functionality down to 1.6 V.
Does the R7F100GJG2DFA#AA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GJG2DFA#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual capacitance (8×8 matrix = 64 keys). It operates within 1.8–5.5 V, includes built-in noise cancellation, automatic drift compensation, and supports touch detection during STOP mode with wake-up capability-enabling responsive, low-power HMI designs without external touch controllers.
How many UART/UARTA channels does the R7F100GJG2DFA#AA0 support, and is LIN bus protocol supported?
The R7F100GJG2DFA#AA0 supports up to six UART/UARTA channels, with full LIN bus protocol support implemented in hardware on all UARTA modules. This includes automatic LIN header detection, checksum calculation, and sync field generation-enabling direct connection to LIN transceivers for automotive body electronics or industrial sub-networks without software protocol stack overhead.
What low-power modes are available on the R7F100GJG2DFA#AA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GJG2DFA#AA0 offers HALT, STOP, and SNOOZE modes. STOP mode powers down the CPU, flash, and RAM while retaining register and RAM content (210 nA for 4 KB RAM). SNOOZE mode goes further: it disables the CPU, flash, and RAM entirely while allowing the dedicated SNOOZE mode sequencer (SMS) to autonomously execute up to 32 pre-programmed steps-including ADC conversions, comparisons, and GPIO toggles-without any CPU intervention or wake-up latency.
Can the R7F100GJG2DFA#AA0 perform background data flash writes while executing code from program flash?
Yes, the R7F100GJG2DFA#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash blocks-enabling seamless runtime updates of calibration tables, device configuration, or logging data without halting application execution or requiring complex dual-bank firmware schemes.
