Product details
Overview
R7F100GEF3CNP#AA0 from Renesas is a 40-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and SAU for industrial control, sensor nodes, and HMI applications.
For engineers reviewing the R7F100GEF3CNP#AA0 datasheet, R7F100GEF3CNP#AA0 pinout, R7F100GEF3CNP#AA0 application, or R7F100GEF3CNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, -40 to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power operation, and hardware-accelerated CTSU2L supporting up to 64 keys in mutual-capacitance matrix configuration.
Technical Context
The R7F100GEF3CNP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable 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, RAM, or flash activation, enabling deterministic low-power event processing.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and a Remote Control Signal Receiver (REMC) with 4-waveform pattern matching. All analog functions-ADC, DAC, comparators, and CTSU2L-are designed for operation across the full 1.6–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and low-code-footprint firmware. |
| Flash Memory | 128 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for robust field updates. |
| RAM | 16 KB on-chip RAM with 210-nA data retention current; preserves critical state during deep sleep without external backup. |
| Supply Voltage | 1.6–5.5 V single supply; eliminates level-shifting requirements in mixed-voltage systems (e.g., 1.8/3.3/5 V peripherals). |
| Operating Temperature | -40 to +105°C (industrial grade); qualified for use in motor drives, PLC modules, and factory automation equipment. |
| Capacitive Sensing | CTSU2L unit supporting self-capacitance (32 keys) or mutual-capacitance (8×8 matrix = 64 keys); no external components required for touch button/slider implementation. |
| ADC | 12-bit resolution, 26-channel input, internal 1.48 V reference and temperature sensor; enables precision analog monitoring without external references. |
| Timers | 16-bit TAU (16 channels), 32-bit interval timer (1×32-bit + 2×16-bit + 4×8-bit modes), RTC with alarm and correction; supports multi-rate timing, PWM generation, and calendar-based wake-up. |
Pinout & Package
Package: 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch), exposed die pad recommended to be connected to VSS for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

The R7F100GEF3CNP#AA0 provides UARTA (up to 6 channels), IICA (up to 10 channels), and SAU-based CSI/SPI/I2C (up to 8 channels), all implemented via multiplexed pins (e.g., P10–P17, P60–P62, P70–P73). Pin function assignment is controlled by the Peripheral I/O Redirection Register (PIOR), allowing flexible interface allocation without changing PCB layout.
Can the R7F100GEF3CNP#AA0 perform flash memory updates while executing application code?
Yes-the R7F100GEF3CNP#AA0 supports Background Operation (BGO) for its 8 KB data flash. Application code runs from code flash while data flash is rewritten, enabling seamless field updates, calibration storage, or secure key management without halting real-time tasks or introducing interrupt latency.
What is the purpose of the SNOOZE mode sequencer (SMS) in the R7F100GEF3CNP#AA0, and what operations does it support?
The SNOOZE mode sequencer (SMS) in the R7F100GEF3CNP#AA0 executes up to 32 preloaded commands-including value comparison, addition, branching, and peripheral register access-without waking the CPU, RAM, or flash.
