Product details
Overview
R7F100GMH3CFA#AA0 from Renesas is an RL78/G23 80-pin industrial-grade 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. It delivers ultra-low power (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports SNOOZE mode for autonomous low-power sensor polling in battery-powered HMI and industrial control systems.
For engineers reviewing the R7F100GMH3CFA#AA0 datasheet, R7F100GMH3CFA#AA0 pinout, R7F100GMH3CFA#AA0 application, or R7F100GMH3CFA#AA0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, 192 KB flash/20 KB RAM configuration, industrial temperature rating (3C), integrated CTSU2L for up to 64-key mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-free periodic ADC sampling and event processing.
Technical Context
The R7F100GMH3CFA#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC conversions, comparisons, and register updates-without CPU, flash, or RAM activation, reducing system-level power during idle intervals.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain capability. The CTSU2L unit operates across VDD = 1.8–5.5 V and supports both self-capacitance (32 keys) and mutual-capacitance (8×8 matrix, 64 keys) configurations.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMH3CFA#AA0?
The R7F100GMH3CFA#AA0 supports up to 32 MHz CPU operation using the 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 deep-sleep functions, maintaining full functionality down to 1.6 V.
Does the R7F100GMH3CFA#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMH3CFA#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) modes. It operates across VDD = 1.8–5.5 V, includes built-in noise suppression, and requires no external components beyond standard decoupling-enabling direct integration into industrial touch panels and appliance control surfaces.
How does the SNOOZE mode sequencer in the R7F100GMH3CFA#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GMH3CFA#AA0 executes up to 32 preloaded commands-including ADC conversions, value comparisons, and register updates-without waking the CPU, flash, or RAM. This allows autonomous periodic sensor polling and conditional wake-up decisions, reducing average current in battery-operated devices to sub-µA levels while maintaining responsiveness to critical events.
What are the data flash endurance and background operation capabilities of the R7F100GMH3CFA#AA0?
The R7F100GMH3CFA#AA0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports Background Operation (BGO), enabling the CPU to execute code from program flash while simultaneously rewriting data flash. This permits seamless firmware updates, secure parameter storage, and real-time logging without interrupting application execution.
Is the R7F100GMH3CFA#AA0 pin-compatible with other RL78/G23 variants in the same 80-pin LQFP package?
Yes, all RL78/G23 80-pin LQFP variants-including R7F100GMH3CFA#AA0, R7F100GMJ3CFA#AA0, and R7F100GML3CFA#AA0-share identical pinouts, electrical characteristics, and peripheral mappings. Memory size differences (192 KB vs. 256 KB vs. 384 KB) do not affect pin function allocation, enabling drop-in replacement during design iteration or cost optimization.
