Product details
Overview
R5F101GGDNA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and targets battery-powered industrial sensors and low-power HMI control units.
For engineers reviewing the R5F101GGDNA#U0 datasheet, R5F101GGDNA#U0 pinout, R5F101GGDNA#U0 application, or R5F101GGDNA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), integrated RTC with calendar/alarm, 10-bit 26-channel ADC, and support for SNOOZE mode for ultra-low-power wake-up event handling.
Technical Context
The R5F101GGDNA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with dedicated SFR regions for peripheral control and banked general-purpose registers (8×8-bit ×4 banks).
Peripheral integration includes dual DMA channels (2-clock transfers between SFR and RAM), hardware multiplier/divider/accumulator, 8-channel 16-bit timers, 12-bit interval timer, real-time clock with 99-year calendar and correction function, and three serial interface types: CSI (SPI-compatible), UART/LIN, and I²C/Simplified I²C - all configurable per channel.

FAQ
What is the operating temperature range for the R5F101GGDNA#U0?
The R5F101GGDNA#U0 is rated for industrial operation from –40°C to +105°C, as indicated by the 'G' suffix in its part number. This makes it suitable for deployment in harsh environments such as factory floors, outdoor metering enclosures, and under-hood automotive auxiliary systems where ambient heat exceeds standard commercial-grade limits.
Does the R5F101GGDNA#U0 include on-chip data flash memory?
No, the R5F101GGDNA#U0 does not include on-chip data flash memory. The '101' prefix in the part number explicitly denotes the absence of data flash, distinguishing it from the '100' series (e.g., R5F100GGDNA#U0) which integrates 8 KB of data flash. Firmware must use external non-volatile storage or reserve code flash sectors for parameter storage.
What package type and pin count does the R5F101GGDNA#U0 use?
The R5F101GGDNA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch), identified by the 'NA' suffix and '#U0' tray packaging code. This thermally enhanced, space-efficient package supports reflow soldering and provides 41 user I/O pins plus power/ground connections - ideal for compact industrial control modules.
Can the R5F101GGDNA#U0 operate from a single 1.8 V supply?
Yes, the R5F101GGDNA#U0 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it maintains full functionality including 32 MHz operation (via high-speed oscillator), ADC conversion, and RTC operation - enabling direct interface with 1.8 V logic families and compatibility with LiFePO₄ or two-cell alkaline battery systems.
How many serial communication interfaces does the R5F101GGDNA#U0 support?
The R5F101GGDNA#U0 supports up to eight CSI (SPI-compatible) channels, four UART/LIN channels, and ten I²C/Simplified I²C channels - with flexible pin multiplexing allowing concurrent use of multiple protocols. For example, CSI0, UART1, and I²C2 can operate simultaneously on non-overlapping pins without resource conflict.
