Product details
Overview
R7F100GGL2DFB#BA0 from Renesas is an RL78/G23 16-bit microcontroller featuring 384 KB code flash, 32 KB RAM, and 8 KB data flash in a 48-pin LFQFP (7 × 7 mm, 0.50-mm pitch) package rated for -40 to +85°C operation. It delivers true low-power performance with 41-µA/MHz active current and 210-nA data retention, integrated capacitive touch sensing (CTSU2L), and dual-voltage I/O support for mixed-signal industrial control applications.
For engineers reviewing the R7F100GGL2DFB#BA0 datasheet, R7F100GGL2DFB#BA0 pinout, R7F100GGL2DFB#BA0 application, or R7F100GGL2DFB#BA0 equivalent, key selection criteria include its 384 KB flash capacity, CTSU2L-based touch interface capability, SNOOZE mode sequencer for autonomous low-power sensor polling, and UARTA/LIN support for automotive body electronics integration.
Technical Context
The R7F100GGL2DFB#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 preconfigured processes-including ADC sampling, comparator evaluation, and timer comparisons-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers across multiple sources, and a Realtime Clock with alarm and BCD correction. The device supports background operation during data flash rewriting via BGO and features security functions including flash shield window and block erase prohibition.

FAQ
What is the maximum operating frequency and corresponding instruction execution time for the R7F100GGL2DFB#BA0?
The R7F100GGL2DFB#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 assumes use of the high-speed oscillator with no wait states and applies to basic instructions in the RL78 CISC instruction set. The device also supports ultra-low-speed operation at 32.768 kHz with a 30.5 µs instruction time for ultra-low-power modes.
Does the R7F100GGL2DFB#BA0 support capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGL2DFB#BA0 integrates the CTSU2L capacitive sensing unit. It supports self-capacitance mode (up to 32 independent keys using single-pin electrodes) and mutual capacitance mode (up to 64 keys in an 8×8 matrix configuration). The unit operates across the full VDD range of 1.8–5.5 V and includes built-in noise suppression features essential for reliable touch detection in electrically noisy environments.
What are the key low-power modes supported by the R7F100GGL2DFB#BA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GGL2DFB#BA0 supports HALT, STOP, and SNOOZE modes. STOP mode shuts down the CPU and most peripherals, achieving ultra-low current draw with fast wake-up (< 4 µs). SNOOZE mode uniquely enables autonomous peripheral operation-including ADC conversions, comparator evaluations, and timer comparisons-via the SNOOZE mode sequencer (SMS), all without CPU, RAM, or flash activation. This makes SNOOZE ideal for periodic sensor polling with minimal energy overhead.
Can the R7F100GGL2DFB#BA0 execute code while rewriting data flash memory?
Yes, the R7F100GGL2DFB#BA0 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from code flash memory while simultaneously rewriting data flash sectors. BGO is essential for applications requiring runtime parameter updates or over-the-air firmware patches without interrupting real-time operation or requiring system resets.
What is the purpose of the REGC pin on the R7F100GGL2DFB#BA0, and how must it be connected?
The REGC pin on the R7F100GGL2DFB#BA0 is the bypass capacitor terminal for the internal voltage regulator. It must be connected to VSS via a 0.47 µF to 1 µF ceramic capacitor placed as close as possible to the pin. Failure to properly decouple REGC risks unstable internal LDO operation, leading to erratic behavior, failed wake-ups from low-power modes, or unreliable flash programming sequences.
