Product details
Overview
R7F100GPL2DFA#AA0 from Renesas is a 100-pin, consumer-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, 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 dual 16-bit timer arrays for motor control in battery-powered home appliances.
For engineers reviewing the R7F100GPL2DFA#AA0 datasheet, R7F100GPL2DFA#AA0 pinout, R7F100GPL2DFA#AA0 application, or R7F100GPL2DFA#AA0 equivalent, key selection criteria include its 100-pin LFQFP package, -40°C to +85°C temperature range, 512 KB flash/48 KB RAM configuration, and support for SNOOZE mode sequencer-driven low-power sensor polling without CPU wake-up.
Technical Context
The R7F100GPL2DFA#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential low-power operations using 21 command types, enabling autonomous sensor polling and threshold comparison without CPU, flash, or RAM activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix, 64 keys) modes under 1.8–5.5 V operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPL3CFA#AA0 | Same 100-pin LFQFP package and 512 KB/48 KB memory, but rated for -40°C to +105°C industrial operation | Required for HVAC or factory automation deployments exceeding +85°C ambient | Select when extended temperature range is mandatory; otherwise R7F100GPL2DFA#AA0 offers lower cost for consumer-grade use |
| R7F100GLL2DFA#AA0 | 64-pin LFQFP variant with 512 KB flash/48 KB RAM - identical core/peripherals but 36 fewer I/O pins | Suitable for space-constrained designs where <80 GPIOs are needed (e.g., compact sensor hubs) | Choose for reduced PCB footprint and lower assembly cost when full 100-pin I/O is unnecessary |
Compared with R7F100GPL2DFA#AA0, the R7F100GPL3CFA#AA0 adds industrial temperature support without changing pinout or firmware compatibility, while the R7F100GLL2DFA#AA0 trades I/O count for smaller form factor - both retain identical peripheral sets and low-power architecture.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPL2DFA#AA0?
The R7F100GPL2DFA#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains operation down to 1.6 V, enabling direct use with single Li-ion or two alkaline cells without regulators.
Does the R7F100GPL2DFA#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GPL2DFA#AA0 supports on-chip debugging via the dedicated TOOL0 and TOOLRxD/TOOLTxD pins, implementing Renesas' FINE (Fast In-Circuit Emulator) interface. This enables full breakpoint, watchpoint, and real-time trace capabilities using standard Renesas E2 or E2 Lite debuggers without requiring additional SWD/JTAG pins.
How many capacitive touch channels does the R7F100GPL2DFA#AA0 support, and what configurations are available?
The R7F100GPL2DFA#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8 × 8 matrix). It operates from 1.8–5.5 V and includes automatic noise cancellation, making it suitable for touch panels in humid or EMI-prone environments like kitchen appliances.
What are the key low-power modes available on the R7F100GPL2DFA#AA0, and how do they differ?
The R7F100GPL2DFA#AA0 offers HALT, STOP, and SNOOZE modes. HALT stops the CPU but keeps peripherals running; STOP disables the entire system clock except for RTC and LVD; SNOOZE uses the dedicated sequencer to execute predefined tasks (e.g., ADC read → compare → GPIO toggle) autonomously - all three achieve sub-µA quiescent current, with SNOOZE delivering the lowest average power for periodic sensor polling.
Can the R7F100GPL2DFA#AA0 perform simultaneous serial communications, and which protocols are supported?
Yes, the R7F100GPL2DFA#AA0 supports concurrent serial operation: up to 6 UARTA channels (including LIN-bus compliant), 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. Hardware independence between modules allows simultaneous UART-to-radio, I²C-to-sensor, and SPI-to-display traffic without CPU arbitration or buffer contention.
