Product details
Overview
R7F100GGF3CNP#HA0 from Renesas is an RL78/G23 48-pin, 128 KB code flash, 16 KB RAM ultra-low-power 16-bit MCU operating from 1.6–5.5 V, featuring 210-nA data retention current, 41-µA/MHz active current, and integrated capacitive touch sensing (CTSU2L) for human-machine interface applications in industrial control systems.
For engineers reviewing the R7F100GGF3CNP#HA0 datasheet, R7F100GGF3CNP#HA0 pinout, R7F100GGF3CNP#HA0 application, or R7F100GGF3CNP#HA0 equivalent, key selection considerations include its HWQFN-48 package with 0.5-mm pitch, STOP-mode wakeup latency under 4 µs, 12-bit ADC with 26-channel input, and SNOOZE mode sequencer enabling autonomous low-power sensor polling without CPU intervention.
Technical Context
The R7F100GGF3CNP#HA0 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). It integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential operations using 21 command types-entirely independent of CPU, flash, and RAM-to enable deterministic low-power background processing.
Its peripheral set includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers triggered by interrupts, and dual-clock domain operation with independent high-, middle-, and low-speed on-chip oscillators (±1.0% accuracy at 32 MHz), enabling precise timing control across power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and efficient code density for embedded control. |
| Operating Voltage | 1.6–5.5 V; supports direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Power Consumption | 41 µA/MHz active current; reduces thermal load and extends battery life in portable and energy-constrained designs. |
| Data Retention | 210 nA at 4 KB RAM retention; maintains volatile state during deep sleep with minimal leakage impact on system runtime. |

| Realtime Clock | RTC with alarm, calendar (1 sec–99 years), and clock correction; provides accurate timekeeping for logging, scheduling, and timestamping in unattended systems. |
Pinout & Package
Package: HWQFN-48 (7 × 7 mm, 0.50-mm pitch) with exposed die pad recommended to be connected to VSS for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10–P17 | Multi-function I/O with SAU/UART/SPI/I²C capability | Configurable serial interfaces support simultaneous UARTA (LIN-compliant), IICA, and simplified SPI channels for sensor and actuator communication. |
| P20–P25 | Analog input / AVREFP/AVREFM / CTSU2L electrodes | Direct connection to 12-bit ADC and capacitive sensing unit enables single-chip analog front-end for environmental and touch sensing. |
