Product details
Overview
R7F100GMH2DFB#AA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V. It integrates a capacitive touch sensing unit (CTSU2L), 16-bit timer array (TAU), RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and multiple serial interfaces including UARTA, IICA, and CSI - deployed in industrial human-machine interface modules requiring extended battery life and robust touch control.
For engineers reviewing the R7F100GMH2DFB#AA0 datasheet, R7F100GMH2DFB#AA0 pinout, R7F100GMH2DFB#AA0 application, or R7F100GMH2DFB#AA0 equivalent, key selection criteria include its 80-pin LFQFP-0.5 mm package, -40°C to +85°C industrial temperature grade, 192 KB flash/20 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F100GMH2DFB#AA0 implements the RL78 CPU core with CISC architecture and 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 (SMS) executes up to 32 predefined commands-including ADC sampling, comparator evaluation, and GPIO state checks-without CPU, RAM, or flash activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer capability, and dual voltage detectors (LVD0/LVD1) for programmable brown-out protection. The device supports background operation during data flash rewriting via BGO and features on-chip debugging with flash shield window security.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GMH2DFB#AA0?
The R7F100GMH2DFB#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. This timing is confirmed in the RL78/G23 datasheet Rev.1.40 Section 1.1, and applies under VDD = 1.8–5.5 V and TA = –40°C to +85°C conditions. The R7F100GMH2DFB#AA0 also supports ultra-low-speed operation at 32.768 kHz with a 30.5 µs instruction cycle for RTC-critical tasks.
Does the R7F100GMH2DFB#AA0 support capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMH2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys). It operates within VDD = 1.8–5.5 V and includes automatic drift compensation and noise rejection algorithms. The R7F100GMH2DFB#AA0 datasheet specifies dedicated TSxx pins (e.g., TS00–TS05, TS20–TS27) and CTSU-specific registers for calibration and scan control.
What power-saving modes are implemented in the R7F100GMH2DFB#AA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GMH2DFB#AA0 offers HALT (41 µA/MHz), STOP (0.21 µA), and SNOOZE modes. Unlike STOP mode-which halts CPU, flash, and RAM-the SNOOZE mode sequencer (SMS) autonomously executes up to 32 preloaded commands (e.g., ADC conversion, comparator evaluation, GPIO toggle) using only dedicated SMS hardware, consuming significantly less power than waking the CPU. This enables periodic sensor polling without RAM refresh or flash access, preserving 210-nA data retention.
Can the R7F100GMH2DFB#AA0 perform background data flash rewriting while executing application code from main flash?
Yes, the R7F100GMH2DFB#AA0 supports Background Operation (BGO), allowing the CPU to execute instructions from code flash memory while simultaneously rewriting data flash memory. This capability is enabled by separate flash banks and verified in the RL78/G23 datasheet Section 1.1, with a rated endurance of 1,000,000 write/erase cycles (typ.). The R7F100GMH2DFB#AA0 uses this feature for seamless firmware updates and parameter logging without system interruption.
What is the pin count, package type, and temperature grade of the R7F100GMH2DFB#AA0?
The R7F100GMH2DFB#AA0 is packaged in an 80-pin LFQFP (12 × 12 mm, 0.50-mm pitch) with industrial temperature grade of –40°C to +85°C (denoted by "D" in ordering code suffix). The "FB" in the part number specifies the LFQFP-0.5 mm package, and "2D" confirms the consumer/industrial ambient range per Renesas' part numbering scheme in Figure 1-1 of the datasheet.
