Product details
Overview
R5F101PLAFB#30 from Renesas is a 100-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with no data flash, 512 KB code flash, 32 KB RAM, and industrial-grade -40°C to +105°C operation (G-grade), designed for low-power embedded control in HVAC controllers, smart meters, and motor drive interfaces.
For engineers reviewing the R5F101PLAFB#30 datasheet, R5F101PLAFB#30 pinout, R5F101PLAFB#30 application, or R5F101PLAFB#30 equivalent, key selection criteria include its 512 KB flash capacity, 32 KB RAM, integrated RTC+LVD, 16-bit A/D converter with up to 26 channels, and support for UART/LIN, I²C, and CSI serial interfaces in a compact 14×14 mm package.
Technical Context
The R5F101PLAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), 16-bit timer array (up to 16 channels), and real-time clock with calendar and alarm functions.
Power management includes HALT, STOP, and SNOOZE modes enabling ultra-low power operation (0.57 μA in RTC+LVD-only mode), while peripheral integration covers DMA (4 channels), multiplier/divider/MAC unit, and background operation for data flash rewriting - though this device omits data flash memory entirely per its part number coding ('101' = no data flash).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | Same 100-pin LFQFP package and 512 KB flash, but includes 8 KB data flash and operates at -40°C to +85°C (D-grade) | Preferred where field firmware updates or parameter storage require nonvolatile data retention | Select when data flash endurance (1M cycles) and write background operation are required for configuration logging |
| R5F101PLAFP#30 | Identical core and memory specs, but in 100-pin LQFP (0.65 mm pitch, 14×20 mm); no LFQFP footprint compatibility | Suitable for legacy PCB designs using standard LQFP footprints and higher pin-to-pin spacing tolerance | Choose only if board layout cannot accommodate 0.5 mm pitch; requires PCB redesign due to different land pattern and thermal pad |

FAQ
What is the flash memory configuration of the R5F101PLAFB#30?
The R5F101PLAFB#30 contains 512 KB of code flash memory and no data flash memory - confirmed by its '101' part number suffix ('100' = data flash present, '101' = data flash omitted). This configuration suits applications where firmware storage is primary and parameter logging is handled externally or via external EEPROM/FRAM.
Does the R5F101PLAFB#30 support LIN bus communication?
Yes, the R5F101PLAFB#30 supports LIN bus communication through its UART peripherals, which include LIN protocol features such as automatic sync-break detection, checksum calculation, and slave node response timing control - all implemented in hardware without CPU overhead.
What is the maximum operating frequency and instruction throughput of the R5F101PLAFB#30?
The R5F101PLAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. Its RL78 core achieves minimum instruction execution times of 0.03125 μs at 32 MHz, enabling deterministic real-time control loops in motor and power conversion applications.
How many analog input channels does the R5F101PLAFB#30 support?
The R5F101PLAFB#30 supports up to 26 analog input channels on its 10-bit successive-approximation ADC. Channel selection is software-configurable, and the ADC includes an internal 1.45 V reference voltage and integrated temperature sensor - both usable without external components.
Is the R5F101PLAFB#30 pin-compatible with other RL78/G13 variants in the same package?
No - the R5F101PLAFB#30 shares the 100-pin LFQFP package with other RL78/G13 devices, but pin assignments vary across memory configurations and feature sets. Always verify pin mapping against the specific R5F101PLAFB#30 datasheet (R01DS0131EJ0380), especially for ADC, serial, and timer signals.
