Product details
Overview
R7F100GGH3CFB#AA0 from Renesas is a 48-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 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), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports STOP/SNOOZE modes for battery-powered sensor nodes and industrial HMI control.
For engineers reviewing the R7F100GGH3CFB#AA0 datasheet, R7F100GGH3CFB#AA0 pinout, R7F100GGH3CFB#AA0 application, or R7F100GGH3CFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40 to +105°C industrial temperature rating, CTSU2L-based touch interface capability, and SNOOZE mode sequencer for autonomous low-power peripheral sequencing without CPU wake-up.
Technical Context
The R7F100GGH3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE Mode Sequencer (SMS) capable of executing up to 32 sequential commands across 21 supported operations-enabling autonomous analog measurement, comparison, and I/O control while the CPU, flash, and RAM remain powered down.
Its peripheral set includes a 10-bit A/D converter with up to 26 channels, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and an Event Link Controller (ELCL) that enables hardware-level signal routing between peripherals-eliminating software overhead for event-driven state transitions in real-time control loops.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GGH3CFB#AA0?
The R7F100GGH3CFB#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, 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 wake-up, maintaining full functionality down to 1.6 V.
Does the R7F100GGH3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGH3CFB#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports self-capacitance mode (up to 32 independent keys using single-pin electrodes) and mutual-capacitance mode (up to 64 keys in an 8×8 matrix configuration). Both modes operate within the 1.8–5.5 V VDD range and include noise suppression features optimized for industrial EMI environments.
How does the SNOOZE Mode Sequencer (SMS) in the R7F100GGH3CFB#AA0 reduce system power consumption?
The SNOOZE Mode Sequencer in the R7F100GGH3CFB#AA0 executes pre-programmed command sequences-including ADC conversions, value comparisons, and GPIO updates-while the CPU, flash memory, and most RAM banks remain powered down. This reduces active current to ~1.2 µA, enabling periodic sensor polling or status checks without full wake-up, thereby extending battery life significantly compared to CPU-driven polling loops.
What debug and programming interfaces are supported by the R7F100GGH3CFB#AA0?
The R7F100GGH3CFB#AA0 supports on-chip debugging via the dedicated TOOL0 and TOOLRxD/TOOLTxD pins, compatible with Renesas E2 studio and CS+ IDEs. It includes full background ROM programming capability, boot swapping, and flash shield window protection. No external debug probe is required-standard SWD/JTAG is not implemented; instead, it uses Renesas' proprietary FINE interface over the TOOL pin pair.
Can the R7F100GGH3CFB#AA0 operate reliably in industrial environments with ambient temperatures up to +105°C?
Yes, the R7F100GGH3CFB#AA0 is rated for industrial temperature operation from -40°C to +105°C (denoted by the "C" field code in the part number). Its electrical specifications-including flash write/erase endurance, ADC accuracy, and oscillator stability-are guaranteed across this full range, and the LFQFP package provides adequate thermal dissipation for typical industrial PCB layouts with natural convection cooling.
