Product details
Overview
R7F100GPG2DFB#AA0 from Renesas is an RL78/G23 100-pin, ultra-low-power 16-bit MCU with 96 KB code flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), targeting battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPG2DFB#AA0 datasheet, R7F100GPG2DFB#AA0 pinout, R7F100GPG2DFB#AA0 application, or R7F100GPG2DFB#AA0 equivalent, key selection criteria include its LFQFP-100 (0.5 mm pitch) package, -40°C to +85°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The R7F100GPG2DFB#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 power architecture includes HALT, STOP, and SNOOZE modes - the latter enabling up to 32 sequential low-power operations using 21 built-in commands, independent of CPU, flash, or RAM.
Peripheral integration centers on event-driven autonomy: the Event Link Controller (ELCL) routes signals between peripherals (e.g., ADC completion → timer trigger → DAC output), while the Data Transfer Controller (DTC) supports block, repeat, and chain transfers activated by interrupts - eliminating CPU overhead for memory-mapped peripheral data movement.

Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes 32-step autonomous sequences (e.g., ADC sample → compare → DAC output → sleep) without CPU involvement, reducing average system power by >90% in sensor polling. |
| Event Link Controller (ELCL) | Hardware logic links peripheral events (e.g., ADC EOC → TAU trigger → DAC start), enabling deterministic, zero-CPU-latency signal chains for motor control or power regulation. |
| Data Transfer Controller (DTC) | Offloads memory-to-peripheral transfers (e.g., UART receive buffer → RAM) via interrupt-triggered chain transfers, freeing CPU for application logic during high-bandwidth comms. |
| Capacitive Touch Unit (CTSU2L) | Supports both self- and mutual-capacitance configurations with built-in noise cancellation, enabling reliable touch buttons/sliders on PCBs with no overlay or shield required. |
| Secure Flash Management | Flash shield window and block-erase prohibition prevent unauthorized code modification; self-programming with boot swapping enables safe field firmware updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPG3CFB#AA0 | Same package and pinout; 96 KB flash, but rated for -40°C to +105°C industrial temp range (3C grade vs. 2D). | Required for extended-temperature environments (e.g., factory floor PLCs, automotive under-hood). | Select when ambient operating temperature exceeds +85°C; otherwise, R7F100GPG2DFB#AA0 offers cost-optimized 2D-grade performance. |
| R7F100GLJ3CFB#AA0 | 64-pin LFQFP variant with identical core, 256 KB flash, 24 KB RAM, and same peripheral set - differs only in pin count and memory size. | Used where board space is constrained and fewer I/O or analog channels are needed. | Choose for compact designs with reduced I/O requirements; not pin-compatible due to 64-pin vs. 100-pin footprint. |
Compared with R7F100GPG3CFB#AA0, the R7F100GPG2DFB#AA0 trades extended temperature rating for lower cost in standard industrial environments; compared with R7F100GLJ3CFB#AA0, it delivers 36 additional I/O pins and higher analog channel count at the expense of larger PCB area - making it optimal for feature-rich HMI and sensor aggregation.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPG2DFB#AA0?
The R7F100GPG2DFB#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains full peripheral operation - including 12-bit ADC sampling and UART communication - within this voltage and frequency envelope, validated per Renesas R01DS0395EJ0140 datasheet specifications.
Does the R7F100GPG2DFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPG2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 single-key channels) and mutual-capacitance (8×8 matrix, up to 64 keys). It operates across VDD = 1.8–5.5 V, includes built-in noise cancellation, and requires no external components beyond a single TSCAP capacitor - all confirmed in Section 1.1 and Table 1-2 of the RL78/G23 datasheet R01DS0395EJ0140.
How many serial communication interfaces does the R7F100GPG2DFB#AA0 include, and which protocols are supported?
The R7F100GPG2DFB#AA0 includes UARTA (6 channels, LIN-bus compatible), IICA (10 channels, standard/fast-mode I²C), and CSI (8 channels, SPI-compatible serial interface). It also features a dedicated REMC unit for IR remote signal decoding. These interfaces are physically distributed across multiple pin groups (e.g., P10–P15, P60–P62) and support concurrent operation - verified in Sections 1.1 and Table 1-2 of the official datasheet.
What power-saving modes are available on the R7F100GPG2DFB#AA0, and what is the lowest achievable current draw?
The R7F100GPG2DFB#AA0 supports HALT (0.52 µA), STOP (210 nA with 4 KB RAM retention), and SNOOZE modes. In STOP mode with 4 KB RAM retained, current draw is 210 nA at VDD = 3.0 V and TA = 25°C - the lowest specified operating current. Wake-up sources include external interrupts, RTC alarm, and LVD detection, all documented in Section 1.1 of R01DS0395EJ0140.
Is the R7F100GPG2DFB#AA0 pin-compatible with other RL78/G23 variants, and what package does it use?
The R7F100GPG2DFB#AA0 uses a 100-pin LFQFP package (14 × 14 mm, 0.50-mm pitch, part code FB). It is not pin-compatible with RL78/G23 variants in other packages (e.g., 64-pin LFQFP or 48-pin HWQFN), nor with different pin-count derivatives - pin assignments and peripheral mappings are specific to the 100-pin configuration, as defined in Table 1-1 and Figure 1-1 of the datasheet.
