Product details
Overview
R7F100GGL2DFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 384 KB code flash, 8 KB data flash, and 32 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and supports industrial applications at –40°C to +105°C.
For engineers reviewing the R7F100GGL2DFB#AA0 datasheet, R7F100GGL2DFB#AA0 pinout, R7F100GGL2DFB#AA0 application, or R7F100GGL2DFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP package, 384 KB flash/32 KB RAM configuration, SNOOZE mode sequencer for autonomous low-power sensor polling, and dual-voltage I/O support for mixed-signal interfacing.
Technical Context
The R7F100GGL2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 integrates a SNOOZE mode sequencer (SMS) capable of executing 32 sequential processes using 21 command types without CPU involvement.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling configurable event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance methods-enabling up to 32 single-key or 64 matrix-key touch interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GGL3CFB#AA0 | Same 48-pin LFQFP package and 384 KB/32 KB memory, but rated for industrial temperature (–40°C to +105°C) with 'C' suffix instead of 'D'; identical pinout and peripheral set. | Designed for industrial environments where extended temperature tolerance is mandatory; no functional difference in firmware or hardware design. | Select R7F100GGL3CFB#AA0 when full industrial-grade qualification (including AEC-Q100 not applicable but temp-rated) is required for deployment. |
| R7F100GFL2DFB#AA0 | Same 48-pin LFQFP package but reduced memory: 256 KB code flash, 24 KB RAM; otherwise identical peripheral complement and low-power features. | Suitable for cost-sensitive or space-constrained applications where full 384 KB flash and 32 KB RAM are unnecessary. | Choose R7F100GFL2DFB#AA0 to reduce BOM cost while retaining identical footprint, pinout, and peripheral functionality for scaled-down firmware. |
Compared with R7F100GGL3CFB#AA0, the R7F100GGL2DFB#AA0 shares identical hardware but targets consumer-grade thermal performance; versus R7F100GFL2DFB#AA0, it provides 128 KB more flash and 8 KB more RAM-critical for complex UI stacks or firmware-over-the-air update partitions.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GGL2DFB#AA0?
The R7F100GGL2DFB#AA0 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. The device also supports ultra-low-speed operation at 32.768 kHz, where the minimum instruction time extends to 30.5 µs-enabling precise real-time clock functions with minimal power draw.
Does the R7F100GGL2DFB#AA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGL2DFB#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) configurations. It operates across the full 1.8–5.5 V supply range and includes built-in noise cancellation algorithms, eliminating the need for external touch controller ICs in most HMI designs.
What low-power modes does the R7F100GGL2DFB#AA0 support, and how does SNOOZE mode differ from STOP mode?
The R7F100GGL2DFB#AA0 supports HALT, STOP, and SNOOZE modes. STOP mode halts the CPU and most peripherals while retaining RAM content and allowing fast wakeup (<3.5 µs). SNOOZE mode uniquely enables autonomous peripheral operation-including ADC sampling, comparisons, and GPIO toggling-via the dedicated SNOOZE mode sequencer (SMS), without waking the CPU, flash, or RAM, achieving sub-µA average current in sensor polling applications.
Can the R7F100GGL2DFB#AA0 perform background data flash rewriting while executing application code?
Yes, the R7F100GGL2DFB#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash-enabling seamless firmware parameter updates, logging, or calibration storage without interrupting real-time tasks or requiring full system stalls.
What is the purpose of the REGC pin on the R7F100GGL2DFB#AA0, and how must it be connected?
REGC is the regulator capacitor pin for the internal voltage regulator. It must be connected to VSS via an external capacitor of 0.47 µF to 1 µF to stabilize the internal regulated voltage supply. Failure to connect REGC properly will result in unstable operation or failure to enter low-power modes reliably. This requirement applies to all RL78/G23 devices, including the R7F100GGL2DFB#AA0.
