Product details
Overview
R5F100GGDNA#U0 from Renesas is a 48-pin, 128 KB flash, 8 KB data flash, 8 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V operation, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, and CSI for industrial control and sensor interface applications.
For engineers reviewing the R5F100GGDNA#U0 datasheet, R5F100GGDNA#U0 pinout, R5F100GGDNA#U0 application, or R5F100GGDNA#U0 equivalent, key selection criteria include its HWQFN-48 package, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, self-programmable flash with boot swap, and background data flash rewrite capability.
Technical Context
The R5F100GGDNA#U0 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). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by a dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control logic without external glue logic. The DMA controller supports 4-channel transfers with 2-clock latency between SFR and internal RAM.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100GGDNA#U0?
The R5F100GGDNA#U0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy), consuming 66 μA per MHz in active mode. At full speed, total active current is approximately 2.1 mA. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F100GGDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GGDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. It implements boot swap functionality, allowing validated firmware images to be loaded into alternate banks and activated atomically - a capability confirmed in Section 1.1 "Code flash memory" of the R01DS0131EJ0380 datasheet.
What analog features are integrated into the R5F100GGDNA#U0, and how many channels are available?
The R5F100GGDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), internal 1.45 V reference voltage, and an on-die temperature sensor. These analog resources are accessible on dedicated pins like P20/ANI0 and P21/ANI1, and their configuration is detailed in Section 1.1 "A/D converter" of the R01DS0131EJ0380 datasheet.
Is the R5F100GGDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package - including R5F100GGDNA#U0, R5F100GHANA#U0, and R5F100GFANA#U0 - share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint when memory or peripheral requirements change, as confirmed by Renesas' Pin Configuration diagrams (Section 1.3.4) and Package Outline Drawings (PWQN0048KB-A).
What development tools and software support are available for the R5F100GGDNA#U0?
Renesas provides comprehensive support for the R5F100GGDNA#U0 via the CS+ IDE, e² studio (with GCC RL78 toolchain), and the Renesas Flash Programmer. Hardware tools include the E2 emulator Lite and E2 emulator, both connecting via the TOOLx pins. Driver libraries, HAL APIs, and sample projects for UART, ADC, RTC, and low-power modes are available in the RL78/G13 Firmware Integration Technology (FIT) module - all documented in the R01DS0131EJ0380 datasheet Appendix and Renesas website.
