Product details
Overview
R7F100GLL2DFA#AA0 from Renesas is a 64-pin, consumer-grade RL78/G23 16-bit microcontroller with 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), 16-bit TAU timers, RTC, UARTA/IICA/SAU interfaces, and operates from 1.6–5.5 V across –40 to +85°C for battery-powered HMI and sensor edge nodes.
For engineers reviewing the R7F100GLL2DFA#AA0 datasheet, R7F100GLL2DFA#AA0 pinout, R7F100GLL2DFA#AA0 application, or R7F100GLL2DFA#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 512 KB flash/48 KB RAM configuration, integrated CTSU2L for up to 64-key mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-free low-power periodic sensing.
Technical Context
The R7F100GLL2DFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and subsystem clock (32.768 kHz).
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) for autonomous low-power sensor polling, Logic & Event Link Controller (ELCL) for hardware-triggered peripheral chaining, and Data Transfer Controller (DTC) supporting block, repeat, and chain transfers activated by interrupts - eliminating CPU overhead for memory-mapped peripheral data movement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL3CFA#AA0 | Same 64-pin LFQFP package and 512 KB/48 KB memory, but industrial-grade (–40 to +105°C) and higher VDD tolerance (1.6–5.5 V same). | Required for HVAC control units or factory-floor equipment operating above 85°C ambient. | Select when extended temperature range or AEC-Q200 qualification is mandatory; otherwise R7F100GLL2DFA#AA0 offers lower cost for consumer environments. |
| R7F100GML2DFA#AA0 | 80-pin LQFP variant with identical 512 KB/48 KB memory, same peripherals, but adds 4 extra ADC channels and 2 more UARTA interfaces. | Suitable for complex HMI systems requiring additional analog inputs (e.g., multi-zone temperature sensing) or dual serial protocols (e.g., UART + LIN). | Choose only if pin count expansion is needed; R7F100GLL2DFA#AA0 provides optimal I/O density and cost for 64-pin constrained designs. |

FAQ
What is the maximum operating frequency and corresponding current consumption for the R7F100GLL2DFA#AA0?
The R7F100GLL2DFA#AA0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, with typical active current consumption of 41 µA per MHz. At full speed, this equates to approximately 1.3 mA total active current - verified under VDD = 3.3 V and TA = 25°C per R01DS0395EJ0140 Rev.1.40 Section 1.1.
Does the R7F100GLL2DFA#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GLL2DFA#AA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, or TRNG). Its security features are limited to flash memory protection (block erase prohibition, flash shield window) and secure boot swapping - intended for firmware integrity, not data encryption.
Can the R7F100GLL2DFA#AA0's capacitive touch unit operate reliably in wet or noisy environments?
Yes, the CTSU2L unit in the R7F100GLL2DFA#AA0 incorporates hardware-based noise cancellation and automatic sensitivity adjustment. It supports mutual-capacitance mode (8×8 matrix) which inherently rejects common-mode noise - validated for operation with water droplets and EMI up to 10 V/m per Renesas Application Note R01AN3919JJ0100.
What debug interface does the R7F100GLL2DFA#AA0 use, and is external hardware required?
The R7F100GLL2DFA#AA0 uses the on-chip debug interface accessible via the TOOL0 (pin P40) and TOOLRxD/TOOLTxD (pins P11/P12) signals. No external debug probe is required for basic programming and breakpoint debugging - standard Renesas E2 emulator or E2 Lite supports it out-of-box with SWD-like protocol over these pins.
How many independent PWM outputs can be generated simultaneously on the R7F100GLL2DFA#AA0?
The R7F100GLL2DFA#AA0 supports up to 16 independent PWM outputs using its Timer Array Unit (TAU), with configurable resolution (8/16-bit), dead-time insertion, and complementary output pairs - sufficient for driving multi-phase motor controllers or RGB LED arrays without external timers.
