Product details
Overview
R5F101FAAFP#30 from Renesas is a 44-pin LQFP, 32 MHz RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 12-bit ADC (12 channels), UART/SPI/I²C interfaces, RTC, and operates from 1.6–5.5 V for battery-powered industrial sensor nodes.
For engineers reviewing the R5F101FAAFP#30 datasheet, R5F101FAAFP#30 pinout, R5F101FAAFP#30 application, or R5F101FAAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-latency wake-up in energy-constrained embedded control.
Technical Context
The R5F101FAAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map includes 1 MB address space, with flash organized in 1 KB blocks and security features like block erase prohibition.
Power management includes HALT, STOP, and SNOOZE modes; the latter enables peripheral-triggered wake-up while retaining RAM content and allowing background ADC sampling. The device uses an on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable) and supports DMA transfers requiring only 2 clocks between SFR and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FAAFP#30 | Includes 4 KB data flash; otherwise identical flash/RAM/peripherals | Required when field firmware updates or parameter storage must persist across power cycles without external EEPROM | Select R5F100FAAFP#30 if nonvolatile parameter retention is mandatory; R5F101FAAFP#30 reduces BOM cost where data flash is unused |
| RL78/G14 R5F11FAAFP#30 | Same pinout, adds 16 KB data flash, enhanced EMI immunity, and higher max clock (48 MHz) | Better suited for complex UI-driven devices or those requiring frequent OTA updates | Choose RL78/G14 only if additional data flash capacity or 48 MHz performance is validated in design; migration requires minor toolchain update |
Compared with R5F100FAAFP#30 and RL78/G14 R5F11FAAFP#30, the R5F101FAAFP#30 delivers optimal cost-efficiency for fixed-function industrial controllers where data flash is unnecessary and 32 MHz performance suffices - reducing silicon cost without sacrificing peripheral richness or low-power capability.

FAQ
What is the maximum operating frequency of the R5F101FAAFP#30?
The R5F101FAAFP#30 supports a maximum CPU clock frequency of 32 MHz using the on-chip high-speed oscillator. This yields 41 DMIPS performance and enables real-time control tasks such as motor commutation or sensor fusion. Frequency scaling is supported down to 32.768 kHz for ultra-low-power RTC operation, with instruction execution time ranging from 0.03125 μs to 30.5 μs accordingly. The R5F101FAAFP#30 does not require external crystals for basic operation due to its ±1.0% internal oscillator accuracy.
Does the R5F101FAAFP#30 include on-chip data flash memory?
No, the R5F101FAAFP#30 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, this variant belongs to the data-flash-less family. It provides 64 KB of code flash and 4 KB of RAM, but lacks the 4 KB data flash found in corresponding R5F100x parts. Applications requiring nonvolatile parameter storage must use external EEPROM or FRAM, or select the R5F100FAAFP#30 instead. The R5F101FAAFP#30 retains full self-programming capability for code flash updates.
What package type and pin count does the R5F101FAAFP#30 use?
The R5F101FAAFP#30 uses a 44-pin plastic LQFP package with 10 × 10 mm body and 0.8 mm lead pitch, compliant with JEDEC standard PLQP0044GC-A. The "FA" in the part number denotes LQFP-0.8 mm, and "#30" specifies tray packaging. This package offers robust thermal performance and hand-solderability, making it suitable for industrial control boards and medical devices where reliability and manufacturability are critical. The R5F101FAAFP#30 has 34 general-purpose I/O pins, including 12 ADC inputs and multiple serial interface functions multiplexed on shared pins.
What is the operating temperature range for the R5F101FAAFP#30?
The R5F101FAAFP#30 is rated for industrial operation from -40°C to +85°C, denoted by the "D" grade in Renesas' ordering nomenclature. This qualification ensures reliable functionality across extended thermal cycles encountered in factory automation, outdoor metering, and HVAC equipment. The device maintains specified timing, ADC accuracy, and low-power mode currents across this full range, with the on-chip voltage detector (LVD) offering 14 programmable threshold levels to safeguard operation during brown-out conditions. The R5F101FAAFP#30 does not support the -40°C to +105°C "G" grade variant.
Which communication interfaces are supported by the R5F101FAAFP#30?
The R5F101FAAFP#30 supports three hardware serial interfaces: up to 2 UART channels (one with LIN-bus support), up to 8 CSI channels (Renesas' SPI-compatible interface), and up to 10 I²C/Simplified I²C channels. Specific to the 44-pin LQFP package, it implements UART0 (P30/P31), CSI0 (P10–P12), and I²C0 (P13/P14), with additional peripherals accessible via port multiplexing. These interfaces enable connectivity to sensors, displays, wireless modules, and legacy industrial buses - all while maintaining ultra-low-power operation through peripheral-specific clock gating and SNOOZE-mode compatibility.
