Product details
Overview
R5F104GDAFB#V0 from Renesas Electronics is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G: −40°C to +105°C) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6 V to 5.5 V, and supports ultra-low-power modes including STOP (0.60 μA with RTC+LVD) and HALT (66 μA/MHz), targeting battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104GDAFB#V0 datasheet, R5F104GDAFB#V0 pinout, R5F104GDAFB#V0 application, or R5F104GDAFB#V0 equivalent, key selection criteria include its integrated 10-bit 20-channel ADC, dual UART/LIN support, real-time clock with calendar, and hardware DTC/ELC for deterministic peripheral event handling in resource-constrained embedded systems.
Technical Context
The R5F104GDAFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable from 1–64 MHz) and supports background operation during data flash rewriting (BGO).
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, watchdog timer, two 8-bit DAC outputs, up to two comparators, and serial interfaces: 3–4 UART/LIN channels, 4–10 I²C/Simplified I²C channels, and 3–8 CSI (SPI-compatible) channels - all managed via Event Link Controller (ELC) for zero-cycle latency triggering.

What is the maximum operating frequency and associated performance of the R5F104GDAFB#V0?
The R5F104GDAFB#V0 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and optimized instruction set, enabling deterministic execution of real-time control tasks such as motor commutation or sensor fusion within strict timing budgets.
Does the R5F104GDAFB#V0 support background data flash rewriting while executing code from main flash?
Yes, the R5F104GDAFB#V0 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from code flash memory while simultaneously rewriting the 8 KB data flash - essential for logging sensor data or updating calibration parameters without system interruption.
What are the key low-power modes available on the R5F104GDAFB#V0 and their typical current consumption?
The R5F104GDAFB#V0 offers HALT mode (66 μA/MHz) and STOP mode (0.60 μA with RTC and LVD active). STOP mode retains RAM and register contents while disabling the CPU and most peripherals - ideal for battery-powered applications requiring multi-year operation with periodic wake-up events.
How many analog-to-digital converter (ADC) channels does the R5F104GDAFB#V0 integrate, and what is its resolution?
The R5F104GDAFB#V0 integrates a 10-bit successive-approximation ADC with up to 20 input channels (ANI0–ANI19). It supports internal 1.45 V reference voltage and on-chip temperature sensing, enabling accurate voltage, current, and thermal measurements without external reference components.
Is the R5F104GDAFB#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104GDAFB#V0 is pin-compatible with all RL78/G14 devices in the 48-pin LFQFP (0.5 mm pitch) package, including R5F104GEAFB#V0 and R5F104GHAFB#V0. Pin functions, power domains, and reset behavior are identical - enabling drop-in replacement for capacity or feature upgrades.
