Product details
Overview
R7F100GLK2DFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 48-KB RAM RL78/G23 16-bit MCU operating from 1.6–5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, capacitive touch sensing (CTSU2L), and integrated RTC, UARTA, IICA, and SAU peripherals - deployed in industrial human-machine interfaces and low-power sensor nodes.
For engineers reviewing the R7F100GLK2DFB#AA0 datasheet, R7F100GLK2DFB#AA0 pinout, R7F100GLK2DFB#AA0 application, or R7F100GLK2DFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade, 512-KB code flash with 8-KB data flash, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The R7F100GLK2DFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations using 21 command types, enabling autonomous peripheral sequencing without RAM/CPU/flash activation.
Its logic and event link controller (ELCL) enables hardware-level signal routing between peripherals (e.g., timer output triggering ADC conversion), while the capacitive sensing unit (CTSU2L) supports both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under 1.8–5.5 V operation - all managed via dedicated on-chip circuitry independent of CPU execution.

Applications
| Industrial HMI Panels | Smart Sensor Nodes |
|---|---|
Use Scenario: Touch-enabled control panel for HVAC or PLC operator interface with ambient light adaptation and button feedback. IC Role / Device Role / Timing Role: Main controller executing CTSU2L touch scan, driving buzzer/PCLBUZ outputs, managing UARTA communication with host MCU, and maintaining RTC timekeeping. Use Value: Ultra-low 210-nA STOP mode extends battery life in backup power scenarios; SNOOZE sequencer handles periodic status LED blinking and sensor polling autonomously. | Use Scenario: Battery-powered environmental monitor measuring temperature, humidity, and air quality with wireless telemetry. IC Role / Device Role / Timing Role: Sensor hub aggregating ADC readings (temp/humidity), running CTSU2L for wake-on-touch, and formatting data for UARTA transmission to BLE module. Use Value: 41-µA/MHz active current minimizes energy draw during measurement bursts; integrated 12-bit ADC and temperature sensor eliminate external components. |
| Energy Metering Interfaces | Appliance Control Units |
Use Scenario: Sub-metering module in smart breakers or power strips tracking real-time voltage/current harmonics. IC Role / Device Role / Timing Role: High-precision timing source via RTC and 32-bit interval timer; processes ADC samples synchronized to zero-crossing detection using ELCL-triggered capture. Use Value: Hardware ELCL linking AC zero-crossing input to TAU capture and ADC start ensures deterministic <1 µs jitter - essential for harmonic analysis. | Use Scenario: Washing machine main control board managing motor drivers, water valves, display, and safety interlocks. IC Role / Device Role / Timing Role: System orchestrator handling PWM motor control (TAU), capacitive keypad (CTSU2L), buzzer alerts (PCLBUZ), and LIN-bus communication with door lock module.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GLK2DFB#AA0?
The R7F100GLK2DFB#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator, achieving a typical active current of 41 µA per MHz. At full 32-MHz operation, this translates to approximately 1.31 mA total active current - verified under VDD = 3.3 V, TA = 25°C conditions per the RL78/G23 datasheet Rev.1.40.
Does the R7F100GLK2DFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLK2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on individual pins) and mutual capacitance (up to 64 keys in an 8×8 matrix configuration). It operates across the full 1.8–5.5 V supply range and includes built-in noise cancellation, auto-calibration, and low-power scan modes - all implemented in dedicated hardware without CPU involvement.
What package type and pin count does the R7F100GLK2DFB#AA0 use, and is it RoHS-compliant?
The R7F100GLK2DFB#AA0 uses a 64-pin LFQFP package (10 × 10 mm, 0.50-mm pitch) with exposed pad thermal design. It is fully RoHS-compliant and rated for industrial temperature operation from -40°C to +85°C. The "FB" suffix in the part number explicitly denotes the LFQFP-0.5mm package variant per Renesas' ordering code specification.
Can the R7F100GLK2DFB#AA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GLK2DFB#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 updates, parameter storage, and logging without system interruption or latency penalties.
What are the supported serial communication interfaces on the R7F100GLK2DFB#AA0, and which ones include LIN bus capability?
The R7F100GLK2DFB#AA0 supports up to 6 UARTA channels, 10 IICA (I²C-compatible) channels, and 8 simplified SPI (CSI) channels. Among these, UARTA modules explicitly support LIN bus protocol (LIN 2.2A/SAE J2602 compliant) with automatic header detection, checksum generation, and slave node response timing - confirmed in Section 1.1 of the RL78/G23 datasheet R01DS0395EJ0140.
