Product details
Overview
R7F100GJH2DFA#AA0 from Renesas is an RL78/G23 52-pin LQFP MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating at 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and simplified SPI - deployed in battery-powered consumer HMI and sensor-edge devices.
For engineers reviewing the R7F100GJH2DFA#AA0 datasheet, R7F100GJH2DFA#AA0 pinout, R7F100GJH2DFA#AA0 application, or R7F100GJH2DFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +85°C consumer-grade temperature range, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GJH2DFA#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs and SNOOZE sequencer executing up to 32 preconfigured commands autonomously.
Peripheral integration includes a 21-function SNOOZE mode sequencer (SMS), Logic & Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., ADC trigger → timer → DMA), and CTSU2L capacitive sensing unit supporting both self-capacitance (32 keys) and mutual-capacitance (8×8 matrix) configurations with VDD = 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 |
|---|---|---|---|
| R7F100GLH2DFA#AA0 | Same 52-pin LQFP package, but 512 KB code flash, 48 KB RAM, and extended peripheral set (e.g., additional UARTA/IICA channels). | Targeted at feature-rich industrial HMI where larger code footprint and more serial interfaces are required. | Select when firmware exceeds 128 KB or additional communication channels (e.g., dual UARTA + IICA) are needed. |
| R7F100GJH3CFA#AA0 | Identical memory and peripheral configuration, but rated for -40°C to +105°C industrial temperature range and packaged in tray for industrial logistics. | Required for deployment in automotive cabin modules, factory automation controllers, or outdoor equipment exposed to thermal stress. | Select when ambient operating temperature exceeds +85°C or industrial qualification (IEC 60730 Class B) is mandated. |
Compared with R7F100GLH2DFA#AA0 and R7F100GJH3CFA#AA0, the R7F100GJH2DFA#AA0 offers optimal cost/power balance for consumer-grade applications requiring <128 KB code, moderate peripheral count, and operation strictly within -40°C to +85°C - avoiding over-specification while retaining full RL78/G23 ecosystem compatibility.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GJH2DFA#AA0?
The R7F100GJH2DFA#AA0 operates up to 32 MHz using the high-speed on-chip oscillator, supported across its full 1.6–5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains functional operation down to 1.6 V, enabling direct use with single-cell Li-ion or alkaline batteries without regulators.
Does the R7F100GJH2DFA#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GJH2DFA#AA0 supports on-chip debugging via the dedicated TOOL0 and TOOLRxD/TOOLTxD pins, compatible with Renesas E2 emulator and standard SWD/JTAG debuggers. Debug functionality remains available in HALT and STOP modes, allowing full visibility into register states and memory during ultra-low-power operation.
How many capacitive touch channels does the R7F100GJH2DFA#AA0 support, and what configurations are available?
The R7F100GJH2DFA#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates from 1.8–5.5 V and includes built-in noise cancellation, enabling reliable touch detection in electrically noisy consumer environments without external components.
What are the key differences between the SNOOZE mode and STOP mode in the R7F100GJH2DFA#AA0?
SNOOZE mode keeps the CPU, flash, and RAM powered down while allowing autonomous execution of up to 32 preloaded commands (e.g., ADC sampling, comparison, GPIO toggle) via dedicated hardware sequencer. STOP mode halts all clocks except the 32.768 kHz subsystem clock and RTC; wake-up occurs only via external interrupt or RTC alarm - making SNOOZE ideal for periodic sensing without full wake-up latency.
Can the R7F100GJH2DFA#AA0 perform simultaneous read and write operations on code and data flash memory?
No - the R7F100GJH2DFA#AA0 supports background operation (BGO) only for data flash writes while executing code from flash memory. Code flash programming requires CPU execution from RAM or boot swap; concurrent read/write on the same flash bank is not permitted due to hardware architecture constraints.
