Product details
Overview
R5F100FLAFP#V0 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, ADC, UART, I²C, and SPI interfaces - deployed in industrial motor control, sensor nodes, and smart metering systems requiring low-power operation down to 0.57 μA in RTC+LVD mode.
For engineers reviewing the R5F100FLAFP#V0 datasheet, R5F100FLAFP#V0 pinout, R5F100FLAFP#V0 application, or R5F100FLAFP#V0 equivalent, key selection criteria include its 1.6–5.5 V supply range, -40°C to +85°C industrial temperature grade (D), 44-pin LQFP package with 0.8 mm pitch, and support for background data flash rewriting and hardware DMA.
Technical Context
The R5F100FLAFP#V0 implements the RL78 CPU core with 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, calendar-based real-time clock with alarm and correction, and a 10-bit A/D converter with up to 26 analog inputs and internal 1.45 V reference.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI (SPI-compatible) channels, 16 × 16-bit timers, and a 2-channel DMA controller enabling zero-wait-state transfers between SFR and RAM in just two clocks - optimized for deterministic real-time response in resource-constrained embedded applications.

FAQ
What is the operating voltage range of the R5F100FLAFP#V0?
The R5F100FLAFP#V0 operates from 1.6 V to 5.5 V across its entire temperature range (-40°C to +85°C). This wide supply range supports direct connection to single-cell Li-ion, 3.3 V, or 5 V rails without external regulators - simplifying power architecture in space-constrained designs.
Does the R5F100FLAFP#V0 support in-system programming via UART or SWD?
Yes, the R5F100FLAFP#V0 supports on-chip debug and flash programming via the dedicated TOOLRxD/TOOLTxD pins (P11/P12) using Renesas E2 studio and CS+ tools. It does not implement SWD; debugging uses Renesas' proprietary FINE interface over the same pins used for UART0.
How many analog input channels does the R5F100FLAFP#V0 provide?
The R5F100FLAFP#V0 provides 26 analog input channels (ANI0 through ANI25) accessible via dedicated pins including P20–P27, P30–P37, P40–P47, and P50–P57. The 10-bit A/D converter supports simultaneous sampling with internal 1.45 V reference and temperature sensor readout.
Is the R5F100FLAFP#V0 pin-compatible with other RL78/G13 44-pin variants?
Yes, all RL78/G13 44-pin LQFP variants - including R5F100FLAFP#V0, R5F101FLAFP#V0, and R5F100GLAFP#V0 - share identical pinouts, electrical characteristics, and mechanical dimensions. Software and PCB layouts are interchangeable across this package group.
What is the maximum operating frequency and associated current consumption of the R5F100FLAFP#V0?
The R5F100FLAFP#V0 achieves 32 MHz operation using its high-accuracy on-chip oscillator (±1.0%), consuming 66 μA per MHz in HALT mode. At full speed with peripherals active, typical active current is ~2.1 mA (VDD = 3.3 V, TA = 25°C), scalable downward via clock gating and STOP mode.
