Product details
Overview
R5F100LDAFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F100LDAFA#30 datasheet, R5F100LDAFA#30 pinout, R5F100LDAFA#30 application, or R5F100LDAFA#30 equivalent, key selection criteria include its -40°C to +85°C industrial temperature rating, on-chip debug support, self-programmable flash with boot swap, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100LDAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 1× watchdog timer, 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and up to 10 I²C/Simplified I²C channels - all configurable via register-based control without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LDAFA#30 | No data flash memory (0 KB); otherwise identical core, peripherals, and package. | Not suitable for applications requiring non-volatile parameter storage; requires external EEPROM or FRAM for configuration retention. | Select when firmware storage is sole non-volatile requirement and data logging is handled externally. |
| R5F100LDALA#U0 | Same flash/RAM specs but in 5 × 5 mm HWQFN-32 package (32-pin); fewer I/O (25 vs. 52 usable). | Targeted at space-constrained designs where reduced pin count and smaller footprint outweigh I/O flexibility. | Choose for compact consumer-grade devices where industrial temp range and full I/O are not required. |
Compared with R5F100LDAFA#30, R5F101LDAFA#30 removes data flash to reduce cost and die size but retains identical code flash and real-time performance, while R5F100LDALA#U0 trades I/O count and package size for board area savings - making each variant optimal for distinct mechanical and functional constraints.

FAQ
What is the maximum operating frequency of the R5F100LDAFA#30?
The R5F100LDAFA#30 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C). At this frequency, it delivers 41 DMIPS performance with a minimum instruction time of 0.03125 μs, enabling responsive real-time control loops in motor and power conversion applications.
Does the R5F100LDAFA#30 include an integrated temperature sensor?
Yes, the R5F100LDAFA#30 includes an on-chip temperature sensor usable with the 10-bit ADC. It is enabled only in HS (high-speed main) mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage, allowing accurate ambient temperature monitoring without external components.
How many I/O pins are available on the R5F100LDAFA#30 in its 64-pin LQFP package?
The R5F100LDAFA#30 provides up to 52 general-purpose I/O pins in its 64-pin LQFP package. These include N-ch open-drain capable pins (with 6 V tolerance on select lines), TTL input buffers, and on-chip pull-up resistors - supporting mixed-voltage interfacing with 1.8 V, 2.5 V, and 3.3 V peripherals.
Can the R5F100LDAFA#30 perform flash self-programming while executing code from memory?
Yes, the R5F100LDAFA#30 supports background operation (BGO) for data flash writes, allowing program execution from code flash during data flash rewriting. Its flash library reserves specific RAM regions (e.g., start address F7F00H for R5F100xL variants) to safely manage self-programming routines without halting application code.
What debug interface does the R5F100LDAFA#30 use, and is external hardware required?
The R5F100LDAFA#30 uses Renesas' on-chip debug interface accessible via dedicated TOOL pins (TOOLRxD/TOOLRST), eliminating the need for external JTAG emulators. Full programming, breakpoint debugging, and real-time variable inspection are supported through standard UART-level connections using Renesas CS+ or e² studio IDEs.
