Overview
R5F100GAGNA#20 from Renesas is a 48-pin, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and industrial-grade −40°C to +105°C temperature range. It integrates 16-bit timer (12 channels), 10-bit ADC (24 channels), UART/SPI/I²C interfaces, RTC, and on-chip debug.
For engineers reviewing the R5F100GAGNA#20 datasheet, R5F100GAGNA#20 pinout, R5F100GAGNA#20 application, or R5F100GAGNA#20 equivalent, key selection criteria include its HWQFN-48 package, G-grade industrial temp rating, integrated data flash for parameter storage, low-power sleep modes (HALT/STOP/SNOOZE), and RL78 CPU core delivering 41 DMIPS at 32 MHz.
Technical Context
The R5F100GAGNA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz high-speed oscillator). It supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.
Its peripheral set includes up to 12 × 16-bit timers, real-time clock with calendar/alarm/correction, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and multiple serial interfaces (CSI, UART/LIN, I²C) - all operating across the full 1.6–5.5 V voltage range and −40°C to +105°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGANA#20 | Same 48-pin HWQFN package, identical 128 KB flash/8 KB data flash/12 KB RAM, but A-grade (−40°C to +85°C) instead of G-grade | Suitable for consumer or commercial environments where extended temperature is not required | Select when cost sensitivity outweighs industrial temp needs and ambient stays within 85°C |
| R5F101GAGNA#20 | Same footprint and pinout, but lacks data flash memory (0 KB); otherwise matches core/peripheral specs and G-grade rating | Applicable where parameter storage is handled externally or unnecessary (e.g., fixed-function devices) | Choose when eliminating data flash reduces BOM cost and simplifies firmware update architecture |
Compared with R5F100GAGNA#20, R5F100GGANA#20 trades industrial temperature margin for lower unit cost, while R5F101GAGNA#20 removes data flash entirely-reducing nonvolatile storage capability but enabling simpler flash management and lower licensing fees.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GAGNA#20?
The R5F100GAGNA#20 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time. This flexibility allows precise trade-offs between throughput and power in real-time embedded systems.
Does the R5F100GAGNA#20 support LIN bus communication, and how is it implemented?
Yes, the R5F100GAGNA#20 supports LIN bus communication through its UART peripheral, which includes dedicated LIN-mode features such as automatic break detection, sync field generation, and checksum calculation. This is implemented in hardware without CPU overhead, enabling reliable communication in automotive body electronics and industrial subsystems where LIN is used for cost-effective sensor/actuator networking.
What packaging and lead finish does the R5F100GAGNA#20 use, and why does it matter for manufacturing?
The R5F100GAGNA#20 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with wettable flank leads. This design enables reliable automated optical inspection (AOI) of solder joints and improves first-pass yield in reflow processes. The #20 suffix indicates embossed tape packaging, supporting high-speed pick-and-place assembly-critical for volume production of industrial and medical devices requiring consistent quality and traceability.
How does the data flash functionality of the R5F100GAGNA#20 differ from standard code flash, and what are its practical benefits?
The R5F100GAGNA#20 includes 8 KB of dedicated data flash memory separate from its 128 KB code flash. Unlike code flash, data flash supports background operation (BGO), allowing program execution to continue while data is rewritten-enabling real-time logging, field calibration, and firmware parameter updates without system interruption. With 1 million write cycles and operation down to 1.8 V, it eliminates need for external EEPROM in many industrial designs.
What are the supported low-power modes of the R5F100GAGNA#20, and how do they impact system-level power budgeting?
The R5F100GAGNA#20 supports HALT, STOP, and SNOOZE low-power modes. HALT stops the CPU while preserving RAM and register states (wakeup < 4 μs); STOP disables most clocks and reduces current to 0.57 μA with RTC + LVD active; SNOOZE allows selected peripherals (e.g., ADC, UART) to operate while CPU sleeps. These modes enable precise power budgeting for battery-powered applications-such as extending medical device runtime or reducing HVAC sensor node energy consumption by >95% during idle intervals.
