Product details
Overview
R5F101GGDFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 8 KB RAM, operating at 32 MHz with 41 DMIPS performance and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring precise timing, analog sensing, and LIN/UART communication.
For engineers reviewing the R5F101GGDFB#30 datasheet, R5F101GGDFB#30 pinout, R5F101GGDFB#30 application, or R5F101GGDFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated 10-bit 26-channel ADC with internal 1.45 V reference and temperature sensor.
Technical Context
The R5F101GGDFB#30 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a real-time clock with calendar, alarm, and correction functions alongside a watchdog timer using a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded systems.

FAQ
What is the flash memory configuration of the R5F101GGDFB#30?
The R5F101GGDFB#30 contains 128 KB of on-chip code flash memory with 1 KB erase blocks and no integrated data flash - consistent with the R5F101x series designation indicating omission of data flash. This simplifies firmware architecture for applications where parameters are stored externally or remain static after programming. The R5F101GGDFB#30 supports self-programming of code flash using the on-chip debug interface.
Does the R5F101GGDFB#30 support hardware debugging without external tools?
Yes, the R5F101GGDFB#30 includes a fully integrated on-chip debug circuit compliant with Renesas E1/E20 emulators, enabling real-time breakpoints, watchpoints, and memory inspection without requiring external JTAG adapters. This capability is active across all power modes except HALT and STOP, allowing full visibility into system behavior during ultra-low-power operation and wake-up transitions.
What are the key power-saving features implemented in the R5F101GGDFB#30?
The R5F101GGDFB#30 implements three primary low-power modes: HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD, 0.57 μA), and SNOOZE (selected peripherals active while CPU sleeps). Its 66 μA/MHz active current, programmable voltage detector with 14 threshold levels, and automatic clock gating for unused modules collectively enable energy-efficient operation in battery-powered applications such as wireless sensors and portable instrumentation.
Can the R5F101GGDFB#30 operate across the full industrial temperature range?
No - the R5F101GGDFB#30 is rated for -40°C to +85°C operation (D-suffix), meeting industrial-grade requirements but not the extended -40°C to +105°C range (G-suffix) offered by other RL78/G13 variants. Its thermal design and qualification align with DIN EN 60730-1 Class B safety standards for automatic electrical controls, making it suitable for factory automation, HVAC, and commercial metering applications within this temperature envelope.
How many analog input channels does the R5F101GGDFB#30 support, and what reference options are available?
The R5F101GGDFB#30 supports up to 26 analog input channels via its 10-bit successive-approximation ADC. Reference voltage options include external AVREFP/AVREFM pins, internal 1.45 V bandgap reference, and VDD as reference - selectable per conversion. The internal temperature sensor is routed to ANI2 (P22), enabling direct die-temperature measurement without external components, critical for thermal compensation in precision sensor systems.
