Product details
Overview
R7F100GJF2DFA#AA0 from Renesas is a 52-pin, consumer-grade RL78/G23 16-bit microcontroller 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 (CTSU2L), and rich peripherals including 16-bit TAU timers, RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and UART/I²C/SPI interfaces - deployed in battery-powered home appliances and sensor nodes.
For engineers reviewing the R7F100GJF2DFA#AA0 datasheet, R7F100GJF2DFA#AA0 pinout, R7F100GJF2DFA#AA0 application, or R7F100GJF2DFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power wake-up sequencing without CPU intervention.
Technical Context
The R7F100GJF2DFA#AA0 implements the RL78 CPU core with a 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). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, flash, or RAM activation, enabling deterministic low-power state transitions.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between functions, a Data Transfer Controller (DTC) with chain transfer capability, and a Remote Control Signal Receiver supporting four waveform pattern matches (header, data 0/1, special data) for IR remote decoding - all operating within the same 1.6–5.5 V supply range and industrial-grade thermal envelope.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and low-energy interrupt handling. |
| Operating Voltage | 1.6–5.5 V single supply; supports direct interfacing with 1.8 V, 2.5 V, and 3.0 V logic without level shifters. |
| Flash/RAM | 256 KB code flash + 8 KB data flash + 24 KB RAM; sufficient for complex sensor fusion firmware with background data logging. |

| Capacitive Sensing | CTSU2L unit supporting 32 self-capacitance keys or 64 mutual-capacitance keys; eliminates external touch controller ICs. |
| Timers & RTC | 16-bit TAU (12 channels), 32-bit interval timer, and calendar RTC (1 sec–99 years); enables precise time-stamped event logging and alarm scheduling. |
| Analog Peripherals | 12-bit ADC (26 channels, internal 1.48 V reference), dual 8-bit DACs (0–VDD output), and 2-channel comparator with selectable internal/external reference. |
Pinout & Package
Package: 52-pin plastic LQFP (10 × 10 mm, 0.65-mm pitch), consumer-grade (D suffix), tray packaging (#AA0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | ADC input / UART TX / Timer input | Multi-function pin supporting analog sensing, serial communication, and timing capture - configurable via PIOR register. |
| P01 | ADC input / UART RX / Timer output | Enables full-duplex UART with hardware flow control and synchronized timer-based pulse generation. |
| P10–P17 | SAU/SPI/I²C/UART I/O | Dedicated serial interface pins with flexible peripheral assignment - reduces need for external bus switches or multiplexers. |
