Product details
Overview
R5F101LCAFA#30 from Renesas is a 64-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 64 KB flash memory, 4 KB data flash, 4 KB RAM, 16-bit RL78 CPU core, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101LCAFA#30 datasheet, R5F101LCAFA#30 pinout, R5F101LCAFA#30 application, or R5F101LCAFA#30 equivalent, key selection considerations include its 64-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D-grade), and integrated peripherals including 10-bit ADC (26 channels), UART/LIN (4 channels), I²C (10 channels), and real-time clock with calendar function.
Technical Context
The R5F101LCAFA#30 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and background operation for data flash rewriting during program execution.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and voltage operation from 1.6 V to 5.5 V. The device supports DMA (2-channel), 16×16/32÷32 arithmetic units, and simplified SPI (CSI), UART/LIN, and I²C serial interfaces - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LCAFA#30 | Includes 8 KB data flash; same 64 KB code flash, 12 KB RAM, identical pinout and peripherals | Preferred where field-updatable calibration tables or event logs require nonvolatile storage beyond code flash | Select when data flash persistence is required; otherwise R5F101LCAFA#30 reduces cost and flash programming time |
| R5F101LCDFB#30 | Same core and memory, but 64-pin LFQFP (0.5 mm pitch); different land pattern and thermal pad design | Suitable for higher-density PCBs where 0.5 mm pitch and smaller footprint (10 mm × 10 mm) are critical | Choose for space-constrained designs; requires layout revision due to incompatible footprint and soldering profile |
Compared with R5F100LCAFA#30, this part trades data flash capacity for lower unit cost and faster flash programming, while compared with R5F101LCDFB#30, it offers easier hand-soldering and rework compatibility via the larger 0.65 mm pitch LQFP package.

FAQ
What is the maximum operating frequency of the R5F101LCAFA#30?
The R5F101LCAFA#30 supports up to 32 MHz operation using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –40°C to +85°C. External crystals up to 20 MHz are also supported for precision timing applications requiring tighter stability than the internal oscillator provides.
Does the R5F101LCAFA#30 include on-chip data flash memory?
No, the R5F101LCAFA#30 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, this variant provides 64 KB of code flash only, with no dedicated data flash. Applications requiring nonvolatile parameter storage must use code flash sectors or external EEPROM.
What is the operating temperature range specified for the R5F101LCAFA#30?
The R5F101LCAFA#30 is rated for industrial operation from –40°C to +85°C (D-grade), as confirmed by the "D" suffix in its full ordering code structure and Renesas' RL78/G13 datasheet Section 1.1. This rating applies to all electrical specifications unless otherwise noted in the DC characteristics table.
Which package type does the R5F101LCAFA#30 use?
The R5F101LCAFA#30 uses a 64-pin LQFP package with 0.65 mm pitch, 12 mm × 12 mm body size, and PLQP0064JA-A footprint. The "FA" in the part number explicitly denotes LQFP-0.65 mm, distinguishing it from LFQFP (FB), HWQFN (NA), or VFBGA (BG) variants in the same family.
How many analog input channels does the R5F101LCAFA#30 support?
The R5F101LCAFA#30 supports 26 analog input channels (ANI0 through ANI26), all accessible via dedicated pins and configurable through the AD control registers. The 10-bit ADC operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference and integrated temperature sensor.
