Product details
Overview
R7F100GGN2DFB#BA0 from Renesas is a 48-pin LFQFP-packaged 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), integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, and multiple serial interfaces including UARTA, IICA, and CSI for industrial control and sensor node applications.
For engineers reviewing the R7F100GGN2DFB#BA0 datasheet, R7F100GGN2DFB#BA0 pinout, R7F100GGN2DFB#BA0 application, or R7F100GGN2DFB#BA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40 to +85°C temperature grade (D-field), 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power peripheral operation without CPU wake-up.
Technical Context
The R7F100GGN2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It features a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential operations using 21 command types-enabling autonomous analog measurement, comparison, and event-triggered responses without CPU involvement.
Its peripheral set includes a 12-bit A/D converter with up to 26 channels, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and an Event Link Controller (ELCL) that routes signals between peripherals via configurable logic and flip-flop circuits-supporting complex hardware-triggered workflows independent of software intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GFL2DFB#BA0 | Same 48-pin LFQFP package, but 384 KB flash / 32 KB RAM; higher memory density with identical peripheral set and power profile. | Better suited for applications requiring larger firmware (e.g., OTA update stacks, embedded web servers) or extended data buffering (e.g., multi-day sensor logging). | Select when future firmware growth or enhanced data logging is anticipated; pin-compatible upgrade path with no layout change. |
| R7F100GFJ2DFB#BA0 | Same package and 192 KB flash / 20 KB RAM; lower memory and reduced CTSU2L channel count (24 keys max vs. 32) but identical voltage range and temperature grade. | Targeted at cost-sensitive appliances where touch interface is limited to <20 keys and firmware footprint remains under 160 KB. | Choose for BOM cost optimization where full 256 KB flash and 32-key CTSU2L are unused; shares same footprint and debug interface. |
Compared with R7F100GFL2DFB#BA0 and R7F100GFJ2DFB#BA0, the R7F100GGN2DFB#BA0 provides optimal balance of memory (256 KB flash/24 KB RAM), capacitive sensing capacity (32-key self-capacitance), and ultra-low power (41 µA/MHz), making it ideal for mid-tier industrial HMI and battery-powered sensor nodes requiring field-upgradable firmware and robust touch interfaces.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GGN2DFB#BA0?
The R7F100GGN2DFB#BA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. This timing is confirmed in the RL78/G23 datasheet (R01DS0395EJ0140, Section 1.1) and applies directly to the R7F100GGN2DFB#BA0 variant with its 256 KB flash configuration.
Does the R7F100GGN2DFB#BA0 support hardware-accelerated cryptographic functions?
No, the R7F100GGN2DFB#BA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash memory block erase/write prohibition and boot swapping with flash shield window-intended for basic IP protection rather than runtime encryption. For cryptographic workloads, Renesas recommends the RA family or RL78/I1A variants.
What is the qualified operating temperature range for the R7F100GGN2DFB#BA0?
The R7F100GGN2DFB#BA0 is rated for TA = -40 to +85°C, indicated by the "D" field-of-application code in its part number. This qualifies it for consumer and commercial industrial environments-not extended industrial (-40 to +105°C), which would require a "C"-suffixed variant like R7F100GGN3CFB#BA0.
How many capacitive touch channels does the CTSU2L unit support on the R7F100GGN2DFB#BA0?
The CTSU2L unit on the R7F100GGN2DFB#BA0 supports up to 32 keys in self-capacitance mode and up to 64 keys (8×8 matrix) in mutual-capacitance mode. These capabilities are explicitly specified for the GGN series in the RL78/G23 datasheet (R01DS0395EJ0140, Section 1.1) and validated for the 48-pin LFQFP package configuration.
Is the R7F100GGN2DFB#BA0 pin-compatible with other RL78/G23 48-pin variants such as R7F100GFL2DFB#BA0?
Yes, the R7F100GGN2DFB#BA0 is pin-compatible with all other RL78/G23 48-pin LFQFP variants-including R7F100GFL2DFB#BA0 and R7F100GFJ2DFB#BA0-as confirmed by identical pin configurations in Table 1-1 and Figure 1-1 of the RL78/G23 datasheet (R01DS0395EJ0140). All share the same 48-pin LFQFP-0.5 mm pitch mechanical outline and multiplexed pin function mapping.
