Product details
Overview
R7F100GMG2DFB#BA0 from Renesas is an RL78/G23 80-pin, ultra-low-power 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V; features include 12-bit ADC (26 channels), capacitive touch sensing (up to 64 keys), RTC, and SNOOZE mode sequencer - deployed in industrial sensor nodes and battery-powered HMI controls.
For engineers reviewing the R7F100GMG2DFB#BA0 datasheet, R7F100GMG2DFB#BA0 pinout, R7F100GMG2DFB#BA0 application, or R7F100GMG2DFB#BA0 equivalent, key selection criteria include verified STOP-mode wakeup latency, CTSU2L mutual-capacitance configuration support, and UARTA/LIN compliance for automotive body electronics integration.
Technical Context
The R7F100GMG2DFB#BA0 implements the RL78 CPU core with a 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) capable of executing 32 sequential low-power operations without CPU involvement, using 21 command types including compare, arithmetic, and conditional branch.
Its peripheral set includes dual 16-bit timer arrays (TAU), a 32-bit interval timer with configurable counter modes, and a logic/event link controller (ELCL) enabling hardware-triggered signal routing between peripherals - eliminating software overhead for real-time event chaining in motor control and power management subsystems.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMG2DFB#BA0?
The R7F100GMG2DFB#BA0 operates at up to 32 MHz using the high-speed on-chip oscillator with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20 to +85°C. At 1.6 V minimum supply, maximum frequency is reduced to 24 MHz per datasheet Section 1.1. The device maintains full functionality across its 1.6–5.5 V range, enabling direct battery operation from single Li-ion or multi-cell alkaline sources.
Does the R7F100GMG2DFB#BA0 support hardware-accelerated cryptographic functions?
No, the R7F100GMG2DFB#BA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption tasks. Security is implemented via flash memory block protection, boot swapping with flash shield window, and debug interface lock - sufficient for basic firmware integrity but not for high-assurance secure boot or TLS offload.
Can the CTSU2L unit on the R7F100GMG2DFB#BA0 operate simultaneously with ADC conversions?
Yes, the CTSU2L unit and 12-bit ADC can operate concurrently because they use independent analog front-end circuitry and separate trigger sources. The datasheet confirms no resource contention; CTSU2L uses its own charge-transfer sensing engine while the ADC employs a successive-approximation register (SAR) architecture - enabling simultaneous touch detection and environmental sensor reading without timing conflict.
What is the qualified operating temperature range for the R7F100GMG2DFB#BA0, and how is it indicated in the part number?
The R7F100GMG2DFB#BA0 is qualified for industrial ambient temperatures from –40°C to +105°C, denoted by the "3C" field in its ordering code structure (per Figure 1-1). The "D" in position 15 of the part number indicates consumer-grade (–40°C to +85°C), but the "#BA0" packaging suffix corresponds to industrial-qualified devices shipped in trays - confirmed in Table 1-1 where R7F100GMG2DFB maps to "C" (industrial) application field.
How many UARTA channels does the R7F100GMG2DFB#BA0 support, and what LIN protocol versions are implemented?
The R7F100GMG2DFB#BA0 supports three UARTA channels, each fully compliant with LIN 2.2A and SAE J2602 standards. Each channel includes dedicated sync-break detection, checksum generation (classic and enhanced), and automatic header identification - enabling concurrent management of multiple LIN sub-nodes (e.g., seat control, door module, climate actuator) from a single MCU.
