Product details
Overview
R7F100GPL2DFB#AA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit microcontroller featuring 512 KB code flash, 48 KB RAM, and ultra-low-power operation (41 µA/MHz active, 210 nA data retention). It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), deployed in smart home control panels requiring secure, battery-optimized local processing.
For engineers reviewing the R7F100GPL2DFB#AA0 datasheet, R7F100GPL2DFB#AA0 pinout, R7F100GPL2DFB#AA0 application, or R7F100GPL2DFB#AA0 equivalent, key selection considerations include its LFQFP-100 (0.50-mm pitch) package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous sensor polling, and hardware security features including flash shield window and block erase prohibition.
Technical Context
The R7F100GPL2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs using internal oscillators.
Peripheral integration centers on event-driven autonomy: the Logic and Event Link Controller (ELCL) enables direct signal routing between peripherals without CPU intervention, while the SNOOZE Mode Sequencer (SMS) executes up to 32 preconfigured operations-including ADC sampling, comparison, and GPIO toggling-using only 21 command types, fully independent of CPU, flash, and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GSL2DFB#AA0 | Same 100-pin LFQFP package and industrial temp grade, but with 768 KB flash and 48 KB RAM; identical peripheral set and pinout. | Targeted at applications requiring larger firmware image size (e.g., dual-application partitioning or advanced crypto stacks). | Select when future firmware growth headroom or A/B bank booting is required; no PCB change needed. |
| R7F100GPL3CFB#AA0 | Same 512 KB/48 KB configuration and 100-pin LFQFP, but rated for consumer temp range (–40°C to +85°C) and shipped in LQFP-100 (0.65-mm pitch) package. | Suitable for cost-sensitive, non-industrial applications where extended temperature operation is not required. | Choose for commercial-grade designs with existing LQFP-100 layout; verify thermal margin if ambient exceeds 85°C. |
Compared with R7F100GPL2DFB#AA0, R7F100GSL2DFB#AA0 offers higher flash density for complex firmware without altering board layout, while R7F100GPL3CFB#AA0 trades industrial temperature tolerance for lower cost and alternate packaging-both require validation of thermal and security requirements against the original design intent.

FAQ
What is the maximum operating frequency and associated current consumption for the R7F100GPL2DFB#AA0?
The R7F100GPL2DFB#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator, achieving a typical active current of 41 µA/MHz (1.31 mA total at 32 MHz, VDD = 3.3 V, TA = 25°C). This value is measured under standard conditions with all peripherals disabled except the core and clock system; actual consumption scales linearly with enabled peripherals and I/O activity.
Does the R7F100GPL2DFB#AA0 support hardware encryption or secure boot features?
The R7F100GPL2DFB#AA0 does not integrate dedicated cryptographic accelerators or secure boot ROM. However, it provides flash-level security via block erase prohibition and flash shield window functionality, which prevents unauthorized readout or modification of protected memory regions-enabling customer-implemented secure boot flows using signed firmware images verified in application code.
How many capacitive touch channels does the R7F100GPL2DFB#AA0 support, and what configurations are available?
The R7F100GPL2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8 × 8 matrix). Pin assignments for CTSU2L are fixed to P30 (TSCAP), P31, P50–P51, P60–P62, and P70–P73 as defined in the hardware manual; no external components beyond decoupling capacitors are required.
Can the R7F100GPL2DFB#AA0 perform ADC conversions while in STOP mode?
No-the R7F100GPL2DFB#AA0 cannot execute ADC conversions in STOP mode. However, it supports autonomous ADC triggering in SNOOZE mode via the SNOOZE Mode Sequencer (SMS), allowing low-power periodic sampling without CPU wake-up. The ADC completes conversion and stores results in RAM while the CPU remains halted, consuming only ~210 nA during data retention.
What is the pin compatibility status between R7F100GPL2DFB#AA0 and other RL78/G23 variants in the same package?
R7F100GPL2DFB#AA0 shares identical 100-pin LFQFP (0.50-mm pitch) mechanical footprint and pinout with all other RL78/G23 devices in the FB package variant (e.g., R7F100GSL2DFB#AA0, R7F100GPK2DFB#AA0). Signal mapping, power/ground pin locations, and debug interface pins (TOOL0, TOOLRxD, TOOLTxD) are fully consistent across this package family, enabling drop-in replacement for memory- or feature-scaling upgrades.
