Product details
Overview
R7F100GJG3CFA#AA0 from Renesas is a 52-pin, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, 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 rich peripherals including 16-bit timers, 12-bit ADC (26 channels), UART/LIN, I²C, and SPI - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GJG3CFA#AA0 datasheet, R7F100GJG3CFA#AA0 pinout, R7F100GJG3CFA#AA0 application, or R7F100GJG3CFA#AA0 equivalent, key selection considerations include its 52-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and CTSU2L-based capacitive touch support without external components.
Technical Context
The R7F100GJG3CFA#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting configurable 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, with the latter enabling autonomous peripheral sequencing (32-step, 21 command types) without CPU wake-up.
Peripherals are tightly coupled via the Event Link Controller (ELCL) and Data Transfer Controller (DTC), allowing event-triggered transfers and logic-based signal routing between modules like ADC, timers, and communication interfaces - critical for deterministic real-time response in industrial control loops and touch-driven UIs.

Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GJG3CFA#AA0?
The R7F100GJG3CFA#AA0 operates 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 32 MHz, total active current is approximately 1.31 mA. This value scales linearly with frequency and is validated across the full 1.6–5.5 V supply range per R01DS0395EJ0140 Rev.1.40 Section 1.1.
Does the R7F100GJG3CFA#AA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GJG3CFA#AA0 integrates the CTSU2L capacitive touch sensing unit, supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations. It requires no external RC networks or dedicated touch controller ICs - only electrode traces on the PCB - and includes built-in noise cancellation and auto-calibration per Section 1.1 of the datasheet.
What debug and programming interfaces are available on the R7F100GJG3CFA#AA0?
The R7F100GJG3CFA#AA0 supports on-chip debugging via the single-pin TOOL0 interface (SWD-compatible) and full-featured FINE v2 debug architecture. It also enables mass production programming through the dedicated TOOLRxD/TOOLTxD pins (P11/P12) configured as UART, allowing firmware flashing without JTAG hardware. All debug features are accessible in the 52-pin LQFP package without additional pins.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GJG3CFA#AA0, and what peripherals can it control autonomously?
The SNOOZE mode sequencer in the R7F100GJG3CFA#AA0 executes up to 32 predefined commands (e.g., ADC start, compare result, GPIO toggle) without CPU intervention, consuming just 1.2 µA. It directly controls the ADC, comparators, timers, and GPIOs - enabling autonomous touch scanning or sensor polling cycles. This capability is confirmed in Section 1.1 and Figure 1.12 of R01DS0395EJ0140 Rev.1.40.
Is the R7F100GJG3CFA#AA0 qualified for industrial temperature operation, and what packaging options are offered?
Yes, the R7F100GJG3CFA#AA0 is rated for industrial ambient temperatures from –40°C to +105°C (denoted by "C" in the part number). It is supplied in a 52-pin LQFP package with 0.65-mm pitch (PLQP0052JA-A), shipped in trays (#AA0). No other package variants (e.g., QFN or WFLGA) are assigned to this specific memory/config combination per Table 1-1 of the datasheet.
