Product details
Overview
R7F100GPN3CFA#AA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit microcontroller with 192 KB code flash, 8 KB data flash, and 20 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 (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPN3CFA#AA0 datasheet, R7F100GPN3CFA#AA0 pinout, R7F100GPN3CFA#AA0 application, or R7F100GPN3CFA#AA0 equivalent, key selection criteria include its 100-pin LQFP-0.65mm package, -40°C to +105°C ambient rating, SNOOZE mode sequencer for autonomous low-power operation, and hardware event link controller (ELCL) enabling peripheral-to-peripheral signal routing without CPU intervention.
Technical Context
The R7F100GPN3CFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs.
Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 configurable commands (from 21 available) across timers, ADC, CTSU, and communication units without CPU involvement; the ELCL enables direct event-driven inter-peripheral signaling (e.g., timer overflow triggering ADC conversion or UART transmission).

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPN3CFA#AA0?
The R7F100GPN3CFA#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator, supported across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz with 30.5 µs instruction time for RTC and deep-sleep scenarios. Voltage tolerance is verified per Renesas datasheet R01DS0395EJ0140.
Does the R7F100GPN3CFA#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPN3CFA#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual capacitance (8×8 matrix, up to 64 keys). It operates from 1.8–5.5 V, includes built-in noise cancellation, and uses dedicated pins like P30 (TSCAP) and P31–P37 for scan channels. Configuration is handled via registers - no external components required beyond decoupling capacitors.
How does the SNOOZE mode sequencer (SMS) in the R7F100GPN3CFA#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GPN3CFA#AA0 executes up to 32 pre-programmed operations - such as ADC sampling, value comparison, and GPIO toggling - entirely in hardware without CPU, flash, or RAM activation. This allows the core to remain in STOP mode while background tasks run, cutting average current to near-data-retention levels (210 nA) during idle periods. Real-world implementations show >90% reduction in average power versus CPU-polling architectures.
What serial communication interfaces are integrated into the R7F100GPN3CFA#AA0, and which support LIN bus physical layer compliance?
The R7F100GPN3CFA#AA0 integrates UARTA (up to 6 channels), IICA (up to 10 channels), CSI (up to 8 channels), and REMC (1 channel). UARTA channels explicitly support LIN bus protocol compliance per ISO 17987, including automatic sync-break detection, checksum generation, and configurable baud rates down to 1 kbps - enabling direct connection to automotive and industrial LIN networks without external transceivers.
Is the R7F100GPN3CFA#AA0 pin-compatible with other RL78/G23 variants in the same 100-pin LQFP package?
Yes, all RL78/G23 devices in the 100-pin LQFP-0.65mm package (e.g., R7F100GPG3CFA#AA0, R7F100GPH3CFA#AA0, R7F100GPJ3CFA#AA0) share identical pinouts and electrical characteristics. Memory size (code flash, RAM) and some peripheral enablement vary by part number, but pin function mapping, power sequencing, and reset behavior are fully compatible - enabling one PCB design to support multiple memory/configurations via firmware selection.
