Product details
Overview
R7F100GJN2DFA#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 ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich mixed-signal peripherals including 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered home appliance control panels.
For engineers reviewing the R7F100GJN2DFA#AA0 datasheet, R7F100GJN2DFA#AA0 pinout, R7F100GJN2DFA#AA0 application, or R7F100GJN2DFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensor polling, and CTSU2L capacitive touch unit supporting mutual capacitance matrix configurations.
Technical Context
The R7F100GJN2DFA#AA0 implements the RL78 CPU core with 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 executes up to 32 predefined commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation, enabling deterministic sub-µA wake-up-triggered sensing cycles.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes event signals between peripherals (e.g., timer overflow → ADC trigger → interrupt), and a Data Transfer Controller (DTC) supporting chain transfers across UART, SPI, and memory-reducing CPU load during burst communication. All analog blocks (ADC, DAC, comparator) share common reference options: internal 1.48 V, D/A output, or external voltage.
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 gate count for cost-sensitive designs. |
| Flash Memory | 256 KB code flash + 8 KB data flash; supports background operation (BGO) for seamless firmware updates without halting execution. |
| RAM | 24 KB on-chip RAM; retains full contents at 210 nA in STOP mode, enabling fast resume from deep sleep. |
| Operating Voltage | 1.6–5.5 V single supply; eliminates need for external regulators in multi-cell battery or wide-input industrial applications. |
| Capacitive Sensing | CTSU2L unit supporting 32-key self-capacitance or 64-key 8×8 mutual-capacitance matrix; no external components required for touch buttons/sliders. |
| ADC Resolution | Configurable 8/10/12-bit SAR ADC with 26 input channels and internal 1.48 V reference; suitable for precision sensor signal acquisition. |
| Low-Power Modes | HALT, STOP, and SNOOZE modes; SNOOZE sequencer operates autonomously at ~1.5 µA while monitoring sensors and triggering actions. |
Pinout & Package
Package: 52-pin plastic LQFP (10 × 10 mm, 0.65-mm pitch), consumer temperature grade (-40°C to +85°C), tray packaging (#AA0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | ADC input / UART TX / Timer input | Primary serial interface transmit pin; also serves as 12-bit ADC channel ANI17 and TAU timer input TI00 - enables shared pin usage for compact board layout. |
| P01 | ADC input / UART RX / Timer output | Complementary UART receive pin with ADC channel ANI16 and TAU output TO00 - supports full-duplex comms and analog monitoring on same port. |
| P121 / P122 | Crystal oscillator inputs | Supports external 32.768 kHz crystal (P121) and 1–20 MHz crystal (P122); enables precise RTC timing and high-accuracy system clock generation. |
| P30 / P31 | Capacitive touch sense / RTC / buzzer | TSCAP and TS01 pins dedicated to CTSU2L; P30 provides RTC 1-Hz output and VCOUT0 for touch voltage control - critical for noise-immune touch implementation. |
| P60 / P61 | I²C interface (SCL/SDA) | Hardware I²C bus pins with internal pull-ups; support standard/fast-mode I²C (up to 400 kHz) for connecting sensors, EEPROMs, or displays with minimal GPIO overhead. |
| RESET | Active-low reset input | Asynchronous reset pin with internal pull-up; accepts external reset signals or manual reset button; triggers full system initialization and register reset. |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes 32-step command sequences (ADC read, compare, branch) autonomously - reduces average current to ~1.5 µA during periodic sensor polling without CPU wake-up. |
| Capacitive Touch Unit (CTSU2L) | Supports both self-capacitance (32 keys) and mutual-capacitance (64-key 8×8 matrix) with built-in noise cancellation - eliminates need for external touch controller ICs. |
| Data Flash Background Operation (BGO) | Enables concurrent code execution from flash while rewriting data flash - allows over-the-air parameter updates or logging without system interruption. |
| Event Link Controller (ELCL) | Hardware routing of peripheral events (e.g., timer match → ADC start → interrupt) - removes software polling and ISR overhead for time-critical signal chains. |
| High-Accuracy On-Chip Oscillators | ±1.0% accuracy across 1.8–5.5 V and -20–+85°C for 32 MHz main clock - eliminates external crystal for cost-sensitive applications where timing tolerance permits. |

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GJN2DFA#AA0?
The R7F100GJN2DFA#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains operation down to 1.6 V, enabling direct use with two alkaline or NiMH cells without voltage regulation.
Does the R7F100GJN2DFA#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GJN2DFA#AA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption tasks. Security features are limited to flash block erase/write prohibition and boot swapping with flash shield window - intended for IP protection rather than runtime crypto acceleration.
Can the R7F100GJN2DFA#AA0's capacitive touch unit interface with projected-capacitive (PCAP) displays?
No, the CTSU2L unit in the R7F100GJN2DFA#AA0 supports only self-capacitance (single-touch) and mutual-capacitance (matrix-key) sensing - not full projected-capacitive touchscreens requiring X/Y coordinate interpolation and gesture processing. It is designed for discrete buttons, sliders, and wheels, not multi-touch display overlays.
What debug interface does the R7F100GJN2DFA#AA0 provide, and is external hardware required?
The R7F100GJN2DFA#AA0 integrates on-chip debugging support accessible via the TOOL0 and TOOLRxD/TOOLTxD pins (P40, P11, P12), compatible with Renesas E2 emulator and E2 studio IDE. No external debug probe IC is needed - only a standard SWD/JTAG adapter cable and host PC. Debugging works across all power modes except HALT and STOP.
How many independent UART channels does the R7F100GJN2DFA#AA0 support, and which ones include LIN-bus functionality?
The R7F100GJN2DFA#AA0 supports up to six UART channels, with UARTA (channels 0–2) explicitly certified for LIN 2.2A compliance including automatic sync-break detection, checksum calculation, and slave node response timing. UART0 and UART1 (non-A variants) lack LIN-specific hardware features and require software emulation for LIN protocols.
