Product details
Overview
R7F100GPG3CFB#AA0 from Renesas is a 100-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich peripherals including 16-bit TAU timers, RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPG3CFB#AA0 datasheet, R7F100GPG3CFB#AA0 pinout, R7F100GPG3CFB#AA0 application, or R7F100GPG3CFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power operation, and CTSU2L capacitive sensing unit supporting mutual-capacitance matrix configurations.
Technical Context
The R7F100GPG3CFB#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 (SMS) executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, flash, or RAM activation, enabling deterministic low-power sensor polling.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between functions, a Data Transfer Controller (DTC) supporting chain transfers, and a Remote Control Signal Receiver (REMC) with 4-waveform pattern matching for IR remote decoding - all operating under the same ultra-low-power architecture.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ3CFB#AA0 | Same RL78/G23 family, 64-pin LFQFP, 256 KB flash, but only 24 KB RAM and fewer analog I/O (16 ADC channels vs. 26) | Targeted at space-constrained industrial controls where pin count and analog channel density are lower priorities | Select when board layout requires smaller footprint and full 100-pin I/O expansion is unnecessary |
| R7F100GPJ3CFB#AA0 | Identical 100-pin LFQFP package and 256 KB flash, but rated for consumer temperature range (-40°C to +85°C) and lacks industrial-grade qualification | Suitable for cost-sensitive consumer electronics where extended temperature operation is not required | Choose for non-industrial applications to reduce BOM cost while retaining identical peripheral set and pinout |

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPG3CFB#AA0?
The R7F100GPG3CFB#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and -20°C to +85°C ambient. The device supports full 32-MHz operation down to 1.6 V, though oscillator accuracy degrades below 1.8 V - verified in Renesas R01DS0395EJ0140 Section 1.1.
Does the R7F100GPG3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPG3CFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 single-key channels) and mutual-capacitance (8×8 matrix = 64 keys). It operates at VDD = 1.8–5.5 V and includes built-in noise cancellation - confirmed in Section 1.1 and Table 1-2 of the RL78/G23 datasheet R01DS0395EJ0140.
How many serial communication interfaces does the R7F100GPG3CFB#AA0 provide, and what protocols are supported?
The R7F100GPG3CFB#AA0 provides up to 6 UARTA channels (including LIN-bus support), 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. All are configurable per pin via Peripheral I/O Redirection Register (PIOR), with hardware flow control and clock stretching support - detailed in Section 1.1 "Serial interface" of R01DS0395EJ0140.
What power-saving modes are available on the R7F100GPG3CFB#AA0, and what is the lowest achievable current draw?
The R7F100GPG3CFB#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, it draws 210 nA (typ.) - the lowest specified current. SNOOZE mode enables autonomous peripheral operation (e.g., ADC sampling → compare → wake) at sub-µA average current - values confirmed in Section 1.1 "Ultra-low power consumption technology" of R01DS0395EJ0140.
Is the R7F100GPG3CFB#AA0 pin-compatible with other RL78/G23 variants in the same 100-pin LFQFP package?
Yes, all RL78/G23 devices in the 100-pin LFQFP package (e.g., R7F100GPH3CFB#AA0, R7F100GPJ3CFB#AA0) share identical pinouts and electrical characteristics per pin - verified in Table 1-1 and Figure 1-1 of R01DS0395EJ0140. Function allocation (e.g., ADC channel mapping) may vary by flash/RAM configuration but physical connectivity remains consistent.
