Product details
Overview
R7F100GBH3CFP#AA0 from Renesas is a 32-bit RL78/G23 microcontroller 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), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit timers, 12-bit ADC (up to 26 channels), and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered HMI control units.
For engineers reviewing the R7F100GBH3CFP#AA0 datasheet, R7F100GBH3CFP#AA0 pinout, R7F100GBH3CFP#AA0 application, or R7F100GBH3CFP#AA0 equivalent, key selection criteria include its LQFP-32 package, -40°C to +85°C industrial temperature grade (C-suffix), 32-pin I/O count, integrated CTSU2L for self/mutual-capacitance touch, and 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 min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/accumulate instructions and a 1 MB address space across four register banks.
Power management includes HALT, STOP, and SNOOZE modes; the latter uses a dedicated sequencer executing up to 32 preconfigured commands (from 21 available) to manage peripherals like ADC, timers, and CTSU2L autonomously - eliminating CPU involvement during periodic sensing tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GBJ3CFP#AA0 | Same LQFP-32 package and 32-pin I/O count, but 192 KB code flash and 20 KB RAM | Required when firmware exceeds 128 KB or additional RAM is needed for larger buffers or RTOS heap | Select if future firmware growth or real-time OS usage demands higher memory headroom |
| R7F100GCH3CFP#AA0 | Same 128 KB flash/16 KB RAM, but 48-pin LQFP package with 22 additional I/Os and extra peripherals (e.g., 2nd UARTA, more ADC channels) | Needed when design requires >32 GPIOs, dual UARTA for isolation, or expanded analog sensing | Choose only if pin count or peripheral expansion justifies PCB redesign and cost increase |
Compared with R7F100GBJ3CFP#AA0, the R7F100GBH3CFP#AA0 trades flash/RAM headroom for identical footprint and cost; versus R7F100GCH3CFP#AA0, it retains full peripheral functionality within a smaller, lower-cost 32-pin layout - making it optimal for space-constrained, cost-sensitive industrial controls where memory and I/O are precisely matched.

FAQ
What is the maximum operating frequency and clock source flexibility of the R7F100GBH3CFP#AA0?
The R7F100GBH3CFP#AA0 supports up to 32 MHz operation using its high-speed on-chip oscillator (±1.0% accuracy), selectable from 1–32 MHz. It also integrates independent middle-speed (1–4 MHz) and low-speed (32.768 kHz) oscillators, enabling dynamic clock switching and ultra-low-power RTC operation without external crystals - all configurable via system registers without hardware changes.
Does the R7F100GBH3CFP#AA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GBH3CFP#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It includes hardware noise cancellation, adjustable sensitivity, and automatic calibration - all managed by dedicated registers without CPU overhead, and compatible with standard PCB overlay materials.
How does the SNOOZE mode sequencer in the R7F100GBH3CFP#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GBH3CFP#AA0 executes up to 32 pre-programmed commands (e.g., ADC start, CTSU2L scan, RTC read, RAM store) autonomously - without waking the CPU, accessing flash, or powering RAM. This reduces active current to sub-µA levels during periodic sensing tasks, extending battery life significantly compared to CPU-polling approaches.
What serial communication interfaces are integrated into the R7F100GBH3CFP#AA0, and how many instances are available?
The R7F100GBH3CFP#AA0 integrates three UARTA channels (one supporting LIN-bus), up to six simplified SPI (CSI) channels, and up to ten I²C/Simplified I²C channels - with flexible pin mapping via PIOR registers. All interfaces operate independently and can be used concurrently, enabling multi-sensor hub designs with mixed-protocol connectivity.
Is the R7F100GBH3CFP#AA0 qualified for industrial temperature operation, and what packaging options are offered?
Yes, the R7F100GBH3CFP#AA0 is rated for -40°C to +85°C operation (C-field suffix) and supplied in 32-pin LQFP (7 × 7 mm, 0.80-mm pitch) packaged in trays (#AA0). It is not offered in tape-and-reel or WFLGA variants - this specific part number is exclusively LQFP-32 industrial-grade.
