Product details
Overview
R5F100GAANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces for embedded control in industrial sensors and battery-powered HMI.
For engineers reviewing the R5F100GAANA#W0 datasheet, R5F100GAANA#W0 pinout, R5F100GAANA#W0 application, or R5F100GAANA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, industrial-grade -40°C to +105°C operation (G-grade), on-chip debug support, and BGO-capable data flash for background reprogramming in field-upgradable devices.
Technical Context
The R5F100GAANA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz) and 1 MB address space. It integrates dual-clock domain operation with high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8–16 channels of 16-bit timer, 1-channel 12-bit interval timer, calendar-based RTC with alarm/correction, 2–4 DMA channels, and multi-protocol serial interfaces: CSI (SPI-like), UART/LIN, and I²C/Simplified I²C (3–10 channels), all configurable per pin function via register settings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAAFB#V0 | Same core, memory, and peripherals; differs only in LQFP-48 package (7×7 mm, 0.5 mm pitch) and tray packaging (#V0) | Preferred for prototyping and manual assembly due to larger pitch and exposed leads; less suitable for high-density automated SMT | Select when board layout requires easier solder inspection or hand rework capability |
| R5F101GAANA#W0 | Identical package and pinout but lacks data flash (0 KB); retains same code flash, RAM, and peripheral set | Suitable for cost-sensitive applications where field firmware updates or parameter storage are unnecessary | Choose when data retention requirements are met by external EEPROM or when BGO functionality is not required |

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GAANA#W0?
The R5F100GAANA#W0 operates at up to 32 MHz using its high-accuracy on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability enables both high-throughput control loops and extended battery life in the same design.
Does the R5F100GAANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100GAANA#W0 supports full in-system programming via its on-chip debug interface and includes flash shield window and boot swap functions for secure firmware updates. The 8 KB data flash supports background operation (BGO), allowing the R5F100GAANA#W0 to execute application code from main flash while simultaneously rewriting data flash - essential for over-the-air parameter updates without system interruption.
What analog capabilities does the R5F100GAANA#W0 provide for sensor interfacing?
The R5F100GAANA#W0 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and a factory-calibrated on-die temperature sensor. It supports differential input modes and programmable sample-and-hold timing, enabling direct connection to resistive sensors, thermistors, and bridge transducers without external signal conditioning circuitry - reducing system cost and board area.
How does the R5F100GAANA#W0 manage power in battery-powered applications?
The R5F100GAANA#W0 achieves industry-leading power efficiency with 66 μA/MHz active current and just 0.57 μA in STOP mode with RTC and LVD active. Its HALT, STOP, and SNOOZE modes allow granular power-state control, while the on-chip voltage detector (LVD) provides 14 programmable threshold levels for brown-out protection. These features collectively enable multi-year operation on coin-cell batteries in wireless sensor nodes.
Is the R5F100GAANA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package - including R5F100GAANA#W0, R5F100GCANA#W0, and R5F101GAANA#W0 - share identical pinouts and electrical characteristics. Memory and peripheral differences (e.g., data flash presence, ADC channel count) are implemented internally and do not affect PCB layout, enabling flexible BOM management and last-time buy mitigation across performance tiers.
