Product details
Overview
R7F100GJL2DFA#AA0 from Renesas is a 52-pin, consumer-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 true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 16-bit TAU timers (12 channels), dual UARTA + IICA + CSI interfaces, and RTC with alarm-targeted for battery-powered HMI and sensor-edge applications.
For engineers reviewing the R7F100GJL2DFA#AA0 datasheet, R7F100GJL2DFA#AA0 pinout, R7F100GJL2DFA#AA0 application, or R7F100GJL2DFA#AA0 equivalent, key selection considerations include its 52-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for ultra-low-power periodic wake-up, and CTSU2L support for up to 64-key mutual-capacitance touch panels without CPU intervention.
Technical Context
The R7F100GJL2DFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including ADC sampling, comparator evaluation, and GPIO toggling-without CPU, flash, or RAM activation.
Peripheral integration includes Logic & Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and background operation (BGO) for concurrent code execution during data flash rewriting. All analog functions (ADC, DAC, CMP, CTSU2L) share common voltage references and operate within the full 1.6–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and ultra-low-power sleep/wake cycles. |
| Flash Memory | 256 KB code flash + 8 KB data flash; supports self-programming with boot swapping and flash shield window for secure firmware updates. |
| RAM | 24 KB on-chip RAM; retains full 4 KB at 210 nA in STOP mode-critical for state preservation in energy-harvesting systems. |
| Operating Voltage | 1.6–5.5 V single supply; eliminates need for external regulators in multi-cell battery or wide-input industrial designs. |
| Low-Power Modes | HALT, STOP, and SNOOZE modes; STOP enables 32.768 kHz RTC + CTSU2L wake-up with sub-µA quiescent current. |
| Analog Peripherals | 12-bit ADC (26 ch), 8-bit DAC (2 ch), 2-channel comparator, and CTSU2L unit; all share internal 1.48 V reference and support VDD-referenced operation. |
| Timers & RTC | 16-bit Timer Array Unit (12 channels), 32-bit interval timer, and calendar RTC (1 sec–99 years); RTC alarm and correction enable precise timekeeping in metering and logging. |
| Communication Interfaces | UARTA ×3 (LIN-capable), IICA ×4, CSI ×3; hardware event linking (ELCL) allows autonomous peripheral-to-peripheral triggering without CPU overhead. |
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 / UARTA transmit | Primary serial interface TX for UARTA0; also serves as 12-bit ADC channel ANI17 with TS26 touch-sense capability. |
| P01 | ADC input / UARTA receive | Primary serial interface RX for UARTA0; also serves as 12-bit ADC channel ANI16 with TS27 touch-sense capability. |
| P10–P17 | Serial array unit (SAU) I/O | Configurable CSI/IICA/UARTA pins with hardware FIFO and DTC trigger support-enables zero-CPU SPI/I2C transfers. |
| P30 | RTC output / touch sense / VCOUT | Provides RTC 1-Hz output, CTSU2L touch capacitor drive (TSCAP), and VCOUT0 for comparator reference generation. |
| P60–P61 | IICA bus interface | Dedicated SCLA0/SDAA0 pins with built-in slew-rate control and noise filtering-supports robust I2C communication up to 400 kHz. |
| P121–P122 | Crystal oscillator inputs | Accepts 32.768 kHz crystal (XT1) and optional 1–20 MHz crystal (XT2) for precision timing and clock domain separation. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external reset ICs and manual push-button circuits. |
| VDD / VSS | Power supply terminals | Dual VDD/VSS pairs ensure stable core and I/O rail decoupling; REGC pin requires 0.47–1 µF capacitor to VSS for regulator stability. |
Key Features
| Feature | Design Value |
