Product details
Overview
R7F100GML2DFB#AA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (up to 16 channels), RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), targeting battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GML2DFB#AA0 datasheet, R7F100GML2DFB#AA0 pinout, R7F100GML2DFB#AA0 application, or R7F100GML2DFB#AA0 equivalent, key selection criteria include its 80-pin LFQFP-0.5 mm package, -40°C to +85°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and integrated CTSU2L supporting up to 64-key mutual-capacitance touch panels.
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/MAC instructions and 1 MB address space with four banks of eight 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes - the latter enabling autonomous 32-step command sequencing (e.g., ADC sampling → comparison → GPIO toggle) without CPU wake-up, using only CTSU2L, comparator, and timer resources while drawing microamp-level current.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GML3CFB#AA0 | Same 80-pin LFQFP package, identical peripherals, but rated for -40°C to +105°C industrial temp range and shipped in tray packaging (#AA0 vs #AA0 same form factor) | Required for under-hood automotive or high-temp industrial enclosures where ambient exceeds +85°C | Select when extended temperature operation is mandatory; otherwise R7F100GML2DFB#AA0 offers identical functionality at lower cost. |
| R7F100GLL2DFB#AA0 | 64-pin LFQFP variant with 512 KB flash/48 KB RAM but reduced pin count (64 vs 80) and fewer analog channels (20 vs 26 ADC, no CTSU2L) | Suitable for space-constrained designs with simpler HMI or fewer sensors - lacks mutual-capacitance touch capability | Choose when board area is critical and touch interface is limited to <32 self-cap keys or absent; retains SNOOZE/RTC/BGO features. |
Compared with R7F100GML3CFB#AA0, the R7F100GML2DFB#AA0 trades extended temperature rating for cost efficiency in standard industrial environments; versus R7F100GLL2DFB#AA0, it adds 16 pins, 6 ADC channels, and full CTSU2L support - enabling richer HMI and sensor fusion without external ICs.

FAQ
What is the maximum operating frequency and minimum instruction cycle time for the R7F100GML2DFB#AA0?
The R7F100GML2DFB#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, its minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (subsystem clock), where the minimum instruction time extends to 30.5 µs - enabling flexible trade-offs between performance and power consumption.
Does the R7F100GML2DFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GML2DFB#AA0 integrates the CTSU2L capacitive sensing unit. It supports both self-capacitance mode (up to 32 keys using single pins) and mutual-capacitance matrix mode (up to 64 keys using 8×8 pin configuration). The unit operates across the full VDD range (1.8–5.5 V) and includes built-in noise cancellation - eliminating need for external touch controller ICs.
How many serial communication interfaces does the R7F100GML2DFB#AA0 provide, and which protocols are supported?
The R7F100GML2DFB#AA0 provides up to 6 UARTA channels (with LIN-bus support), 10 IICA channels (I²C-compatible, up to 1 Mbps), and 8 CSI channels (SPI-compatible, with configurable clock polarity/phase). These interfaces are implemented in the Serial Array Unit (SAU) and Serial Interface (IICA/UARTA) modules, with peripheral I/O redirection enabling flexible pin assignment.
What low-power modes are available on the R7F100GML2DFB#AA0, and what is the lowest current draw achievable?
The R7F100GML2DFB#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB of RAM retained, it draws 210 nA (typical). The SNOOZE mode sequencer enables autonomous peripheral operation (e.g., ADC sampling → compare → GPIO toggle) while keeping the CPU, flash, and most RAM powered down - achieving microamp-level active sensing current.
Is the R7F100GML2DFB#AA0 pin-compatible with other RL78/G23 variants, and what package options exist for this memory configuration?
The R7F100GML2DFB#AA0 uses an 80-pin LFQFP (12 × 12 mm, 0.50-mm pitch) package with FB suffix. Within the RL78/G23 family, 512 KB flash variants are offered in 64-pin (GLx), 80-pin (GMx), 100-pin (GPx), and 128-pin (GSx) packages - but pinouts differ across pin counts. No other 80-pin variant shares identical pin mapping; however, the R7F100GML3CFB#AA0 is footprint-compatible with extended temperature rating.
