Product details
Overview
R7F100GGN3CFB#BA0 from Renesas is an RL78/G23 48-pin ultra-low-power 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 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 industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGN3CFB#BA0 datasheet, R7F100GGN3CFB#BA0 pinout, R7F100GGN3CFB#BA0 application, or R7F100GGN3CFB#BA0 equivalent, key selection criteria include its LFQFP-48 (0.5 mm pitch) package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power operation, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing - supporting high-speed execution at 32 MHz (0.03125 µs min) or ultra-low-speed operation at 32.768 kHz (30.5 µs min). Its power management includes HALT, STOP, and SNOOZE modes, with 41 µA/MHz active current and 210 nA data retention for 4 KB RAM.
Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 processes using 21 command types without CPU, RAM, or flash access; the Event Link Controller (ELCL) enables direct signal routing between peripherals (e.g., timer output → ADC trigger → DMA transfer); and the CTSU2L supports self- and mutual-capacitance touch with up to 64 keys in matrix configuration.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GGN3CFB#BA0?
The R7F100GGN3CFB#BA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. This timing is achievable across the full 1.8–5.5 V supply range and -20°C to +85°C ambient temperature, with oscillator accuracy maintained at ±1.0%.
Does the R7F100GGN3CFB#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGN3CFB#BA0 integrates the CTSU2L capacitive touch sensing unit. It supports self-capacitance mode (up to 32 independent keys using single pins) and mutual-capacitance matrix mode (up to 64 keys in an 8×8 configuration). Both modes operate within the 1.8–5.5 V VDD range and include built-in noise cancellation features for reliable operation in electrically noisy industrial environments.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GGN3CFB#BA0, and what is its power impact?
The SNOOZE mode sequencer (SMS) in the R7F100GGN3CFB#BA0 executes up to 32 pre-programmed steps using 21 available commands - such as ADC conversion, value comparison, and GPIO control - entirely without CPU, RAM, or flash involvement. This reduces active current to just 1.2 µA typical, enabling battery-powered devices to achieve multi-year operation on coin cells when paired with periodic wake-up intervals.
Can the R7F100GGN3CFB#BA0 perform concurrent operations like running code while rewriting data flash memory?
Yes, the R7F100GGN3CFB#BA0 supports Background Operation (BGO) for data flash. While executing instructions from code flash memory, the MCU can simultaneously rewrite data flash sectors - enabling real-time parameter updates, logging, or firmware configuration changes without halting application code or introducing system latency.
What are the key differences between the R7F100GGN3CFB#BA0 and the pin-compatible R7F100GFL3CFB#BA0?
The R7F100GGN3CFB#BA0 and R7F100GFL3CFB#BA0 share identical LFQFP-48 packaging, pinout, and peripheral feature set. The primary difference is memory capacity: R7F100GGN3CFB#BA0 provides 512 KB code flash and 48 KB RAM, whereas R7F100GFL3CFB#BA0 offers 384 KB code flash and 32 KB RAM.
