Product details
Overview
R7F100GGF3CFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V, featuring ultra-low-power operation (41 µA/MHz), capacitive touch sensing (CTSU2L), and integrated RTC, UARTA, IICA, and SAU peripherals for industrial control and sensor interface applications.
For engineers reviewing the R7F100GGF3CFB#AA0 datasheet, R7F100GGF3CFB#AA0 pinout, R7F100GGF3CFB#AA0 application, or R7F100GGF3CFB#AA0 equivalent, this page delivers verified electrical specs, package mapping, functional role in low-power embedded systems, and validated alternative options for design-in continuity and supply resilience.
Technical Context
The R7F100GGF3CFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power peripheral sequencing without CPU wake-up, and an Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals.
Its analog subsystem includes an 8-/10-/12-bit ADC (26 channels), dual 8-bit DAC outputs, two comparators with selectable internal/external reference, and a dedicated capacitive sensing unit (CTSU2L) supporting up to 64 keys via mutual capacitance matrix - all operating within the 1.8–5.5 V VDD range and qualified for -40°C to +105°C industrial ambient temperature.

The R7F100GGF3CFB#AA0 supports up to 32 MHz operation using the 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; accuracy is ±1.0% over -20°C to +85°C and VDD = 1.8–5.5 V. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and standby functions.
Does the R7F100GGF3CFB#AA0 support hardware-based capacitive touch sensing, and how many keys can it manage?
Yes, the R7F100GGF3CFB#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 configuration). It operates within 1.8–5.5 V, includes automatic tuning and noise cancellation, and uses dedicated CCD00–CCD06 pins for electrode connections - no external components required.
What low-power modes are available on the R7F100GGF3CFB#AA0, and what is the typical current consumption in each?
The R7F100GGF3CFB#AA0 offers HALT, STOP, and SNOOZE modes. HALT draws ~1.2 µA (RAM retained); STOP draws ~0.23 µA (with RTC running); SNOOZE draws ~1.5 µA while executing autonomous peripheral sequences. Active-mode current is 41 µA/MHz at 32 MHz. Data retention in 16 KB RAM consumes only 210 nA - verified at -40°C to +105°C.
Can the R7F100GGF3CFB#AA0 perform simultaneous program execution and data flash rewriting?
Yes, the R7F100GGF3CFB#AA0 supports Background Operation (BGO) for data flash, allowing CPU code execution from program memory while rewriting the 8 KB data flash. This enables reliable firmware updates, parameter logging, or calibration storage without halting real-time tasks - with 1,000,000 write/erase cycles rated at typical conditions.
Is the R7F100GGF3CFB#AA0 pin-compatible with other RL78/G23 variants in the same 48-pin LFQFP package?
Yes, all RL78/G23 devices in the 48-pin LFQFP package (e.g., R7F100GGF3CFB#AA0, R7F100GGJ3CFB#AA0, R7F100GGL3CFB#AA0) share identical pinouts, electrical characteristics, and package dimensions. Memory size, clock options, and peripheral enablement differ by part number, but PCB layout and interconnect remain fully interchangeable.
