Product details
Overview
R5F100GGGNA#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 operation. It integrates 16-bit timer (12 channels), 10-bit ADC (26 channels), real-time clock, UART/LIN, I²C, CSI, DMA (4 ch), and hardware multiplier/divider for embedded control in battery-powered and thermally constrained systems.
For engineers reviewing the R5F100GGGNA#20 datasheet, R5F100GGGNA#20 pinout, R5F100GGGNA#20 application, or R5F100GGGNA#20 equivalent, key selection criteria include its HWQFN-48 package with 0.5 mm pitch, G-grade temperature rating, on-chip debug support, self-programmable flash with boot swap, and background data flash rewriting capability - all critical for industrial motor control, sensor hubs, and smart metering designs requiring long-term reliability and low quiescent current.
Technical Context
The R5F100GGGNA#20 implements the RL78 CPU core with 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 subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size, security-protected erase/write), 8 KB data flash (1M rewrite cycles, BGO supported), and 12 KB SRAM - enabling robust firmware updates and nonvolatile parameter storage without halting application execution.
Peripherals are tightly integrated for deterministic real-time control: four DMA channels enable zero-CPU-overhead transfers between SFRs and RAM (2-cycle latency); the 10-bit ADC supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor; and dual UART channels with LIN bus compliance simplify automotive body electronics and industrial serial communication interfaces.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100GGGNA#20?
The R5F100GGGNA#20 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency, active-mode current is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripherals enabled. In STOP mode with only RTC and LVD active, it draws just 0.57 μA, making it ideal for ultra-low-power wake-on-event applications.
Does the R5F100GGGNA#20 support in-system programming and secure firmware updates?
Yes, the R5F100GGGNA#20 supports full in-system programming via on-chip debug interface (SWD) and includes boot swap functionality for safe firmware updates. Its flash shield window and block-erase prohibition features prevent unauthorized access or corruption of protected code sections - critical for certified industrial and metering applications requiring secure field upgrades.
How many analog input channels does the R5F100GGGNA#20 support, and what ADC resolution and reference options are available?
The R5F100GGGNA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25). It supports internal 1.45 V reference voltage and external AVREFP/AVREFM inputs. The temperature sensor and internal reference are available only in HS (high-speed main) mode, enabling accurate thermal monitoring and sensor calibration without external components.
What communication interfaces are integrated into the R5F100GGGNA#20, and which support LIN bus physical layer compliance?
The R5F100GGGNA#20 includes multiple serial interfaces: up to 10 I²C/Simplified I²C channels, 8 CSI (SPI-compatible) channels, and 4 UART channels. Two UART channels meet ISO 9141-2 and SAE J2602 LIN bus timing specifications - allowing direct connection to LIN transceivers for automotive body electronics and industrial distributed control networks.
Is the R5F100GGGNA#20 pin-compatible with other RL78/G13 variants in the same package, and what are the key memory differences?
Yes, the R5F100GGGNA#20 is pin-compatible with all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100FGGNA#20, R5F100JGGNA#20). Key memory differences include flash (96 KB vs. 128 KB), data flash (4 KB vs. 8 KB), and RAM (8 KB vs. 12 KB). This enables scalable firmware reuse across product tiers while maintaining identical PCB layout and signal routing.
