Product details
Overview
R7F100GLG2DFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB code flash, 48-KB RAM RL78/G23 16-bit MCU with true low-power operation (41 µA/MHz), integrated capacitive touch sensing (CTSU2L), and industrial-grade temperature range (−40 to +105°C). It integrates UARTA, IICA, SAU, RTC, 16-bit TAU, 12-bit ADC, 8-bit DAC, and SNOOZE mode sequencer for battery-powered HMI and sensor control applications.
For engineers reviewing the R7F100GLG2DFB#AA0 datasheet, R7F100GLG2DFB#AA0 pinout, R7F100GLG2DFB#AA0 application, or R7F100GLG2DFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, 512-KB flash/48-KB RAM configuration, −40 to +105°C industrial rating, and support for self-programming with flash shield window and background data flash rewriting.
Technical Context
The R7F100GLG2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling ultra-low-power intermittent operation via a dedicated sequencer that executes up to 32 processes without CPU, flash, or RAM activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under VDD = 1.8–5.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL2DFB#AA0 | Same 64-pin LFQFP package and 512-KB flash, but 32-KB RAM (vs. 48 KB); identical peripheral set and temperature grade | Lower RAM capacity limits complex state machines or large buffer requirements (e.g., audio streaming, multi-sensor fusion) | Select when application fits within 32 KB RAM and cost optimization is prioritized over headroom |
| R7F100GLK3CFA#AA0 | 64-pin LQFP (0.65-mm pitch), 384-KB flash, 24-KB RAM, same −40 to +105°C rating; lacks HWQFN-compatible pinout | Larger footprint and lower memory reduce suitability for space-constrained or high-performance logging applications | Choose only if legacy LQFP layout reuse is mandatory and 384 KB flash suffices for firmware scope |
Compared with R7F100GLL2DFB#AA0 and R7F100GLK3CFA#AA0, the R7F100GLG2DFB#AA0 delivers highest on-chip RAM (48 KB) in the 64-pin LFQFP industrial variant - enabling larger real-time buffers, deeper nested interrupts, and more robust firmware-over-the-air staging without external memory.

Does the R7F100GLG2DFB#AA0 support in-system programming and secure firmware updates?
Yes, the R7F100GLG2DFB#AA0 supports full in-system programming via on-chip debugging and self-programming capabilities. It includes a flash shield window feature that allows selective write-protection of memory regions, and supports boot swapping to enable fail-safe firmware updates. These features are fully operational in the R7F100GLG2DFB#AA0's 512-KB code flash with 2-KB erasable blocks.
How many capacitive touch channels does the R7F100GLG2DFB#AA0 support, and what configurations are available?
The R7F100GLG2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (one pin per key) or up to 64 mutual-capacitance keys (8×8 matrix). Pin assignments such as P30 (TSCAP), P60 (CCD04), and P61 (CCD05) are designated for CTSU2L operation and can be configured via register settings - all within the device's specified VDD = 1.8–5.5 V operating range.

The R7F100GLG2DFB#AA0 provides multiple serial interfaces: up to 6 UARTA channels (including LIN-bus support), up to 10 I²C/Simplified I²C channels, and up to 8 Simplified SPI (CSI) channels. Specific instance counts depend on pin multiplexing - for example, P60/P61 serve as SCLA0/SDAA0 for I²C, while P10–P12 support CSI0/SAU0 functions. All interfaces operate across the full −40 to +105°C temperature range.
Is the R7F100GLG2DFB#AA0 pin-compatible with other RL78/G23 variants in the same 64-pin LFQFP package?
Yes, all RL78/G23 devices in the 64-pin LFQFP (FB) package - including R7F100GLG2DFB#AA0, R7F100GLL2DFB#AA0, and R7F100GLK2DFB#AA0 - share identical pinouts and mechanical dimensions. Function allocation (e.g., ADC channel mapping, timer outputs) is consistent across the family, enabling hardware reuse when migrating between flash/RAM configurations within the same package.
