Product details
Overview
R7F100GML2DFA#AA0 from Renesas is an RL78/G23 80-pin LQFP microcontroller 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 (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GML2DFA#AA0 datasheet, R7F100GML2DFA#AA0 pinout, R7F100GML2DFA#AA0 application, or R7F100GML2DFA#AA0 equivalent, key selection considerations include its 80-pin LQFP-0.65mm package, -40°C to +85°C consumer-grade temperature range, SNOOZE mode sequencer for autonomous low-power peripheral sequencing, and hardware-accelerated CTSU2L supporting up to 64 keys in mutual-capacitance matrix configuration.
Technical Context
The R7F100GML2DFA#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power architecture includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer that executes up to 32 preconfigured commands (e.g., ADC sampling, timer compare, CTSU scan) without CPU wake-up.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (24 channels), 8-bit DAC (2 channels), 2 comparators, 10-channel I²C/Simplified I²C, 6-channel UARTA (LIN-supported), and 8-channel CSI (SPI-compatible). The ELCL logic controller enables event-driven signal routing between peripherals without software intervention.

FAQ
What is the maximum operating frequency and associated current consumption for R7F100GML2DFA#AA0?
The R7F100GML2DFA#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator, drawing 41 µA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, total active current is approximately 1.31 mA. This value scales linearly with clock frequency, enabling dynamic voltage/frequency scaling to optimize power versus performance.
Does R7F100GML2DFA#AA0 support hardware debugging, and what interface is used?
Yes, R7F100GML2DFA#AA0 supports on-chip debugging via the single-wire SWD interface using pins P40 (TOOL0) and RESET. It enables full breakpoint, watchpoint, and memory inspection capabilities through Renesas E2 studio and compatible debug probes - no additional debug header or JTAG adapter required.
Can R7F100GML2DFA#AA0 perform simultaneous analog measurements on multiple channels?
Yes, R7F100GML2DFA#AA0's 12-bit ADC supports sequential scanning of up to 24 analog inputs with automatic channel selection and result storage in dedicated RAM buffers. Conversion can be triggered by software, timer overflow, or ELCL events - enabling deterministic multi-channel acquisition without CPU intervention.
What is the purpose of the REGC pin on R7F100GML2DFA#AA0, and how must it be connected?
The REGC pin on R7F100GML2DFA#AA0 connects to the internal voltage regulator's stabilization capacitor. It must be tied to VSS through a 0.47–1.0 µF ceramic capacitor placed adjacent to the pin. Failure to do so causes unstable internal regulation, leading to erratic reset behavior and potential flash programming failure during development.
How does the SNOOZE mode sequencer in R7F100GML2DFA#AA0 reduce system power compared to conventional polling?
The SNOOZE mode sequencer in R7F100GML2DFA#AA0 executes predefined peripheral operations (e.g., ADC conversion → comparison → CTSU scan → sleep) autonomously at sub-microamp current, eliminating CPU wake-up, instruction fetch, and context save/restore overhead. This reduces average system current by up to 92% versus CPU-polling architectures in intermittent-sensing applications.
