Product details
Overview
R5F101FEDFP#30 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade operation (−40°C to +85°C). It integrates a 10-bit ADC (26 channels), RTC, UART/LIN, I²C, SPI, 16-bit timers, DMA, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in metering, motor drives, and sensor nodes.
For engineers reviewing the R5F101FEDFP#30 datasheet, R5F101FEDFP#30 pinout, R5F101FEDFP#30 application, or R5F101FEDFP#30 equivalent, key selection criteria include its 96 KB code flash with self-programming, 8 KB data flash supporting background rewriting (1M cycles), 26-channel 10-bit ADC with internal reference, and LQFP-44 package compatibility with industrial temperature range and LIN bus support.
Technical Context
The R5F101FEDFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It supports multiple low-power states-HALT, STOP, and SNOOZE-with dedicated on-chip oscillators (32 MHz ±1.0% accuracy) and voltage detector (14-level LVD).
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI/SPI channels, 16× 16-bit timers, real-time clock with calendar/alarm, and 2-channel DMA-configured via memory-mapped registers and supported by Renesas' Smart Configurator and e² studio toolchain.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FEDFP#30 | Same 44-pin LQFP package and peripherals, but includes 8 KB data flash and 96 KB code flash - differs only in data flash presence (R5F100x has data flash; R5F101x does not) | Requires data flash for parameter storage; R5F101FEDFP#30 omits it, reducing cost where EEPROM emulation is unnecessary | Select R5F101FEDFP#30 when data flash is unused; choose R5F100FEDFP#30 if runtime NVM parameter logging is required |
| R5F101GEDFP#30 | Same footprint and core, but upgraded to 128 KB code flash, 8 KB data flash, and 12 KB RAM - direct pin-compatible upgrade path | Needed for larger firmware images, enhanced buffer space, or future feature expansion without PCB change | Choose R5F101GEDFP#30 for designs anticipating firmware growth beyond 96 KB or requiring >8 KB RAM for complex protocols |
Compared with R5F100FEDFP#30, the R5F101FEDFP#30 removes data flash to lower unit cost and simplify qualification where nonvolatile parameter storage is handled externally; versus R5F101GEDFP#30, it trades flash/RAM headroom for tighter BOM control in cost-sensitive volume production.

FAQ
What is the maximum operating frequency and core performance of the R5F101FEDFP#30?
The R5F101FEDFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core features a 3-stage pipeline and supports variable instruction execution times-from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed mode-enabling precise trade-offs between throughput and power in the R5F101FEDFP#30.
Does the R5F101FEDFP#30 include data flash memory, and what are its endurance specifications?
No-the R5F101FEDFP#30 does not include data flash memory. Per Renesas' part numbering convention ('101' denotes no data flash), this variant relies on external EEPROM or FRAM for nonvolatile parameter storage. In contrast, the '100' series (e.g., R5F100FEDFP#30) provides 8 KB data flash rated for 1,000,000 write cycles at VDD = 1.8–5.5 V.
What package type and pin count does the R5F101FEDFP#30 use, and is it RoHS-compliant?
The R5F101FEDFP#30 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), identified by the 'FP' suffix and '#30' tray packaging code. It is lead-free and RoHS-compliant, with PLQP0044GC-A as the official Renesas package code. The exposed thermal pad enhances thermal dissipation in continuous industrial operation of the R5F101FEDFP#30.
Which communication interfaces are supported by the R5F101FEDFP#30, and does it support LIN bus?
The R5F101FEDFP#30 supports UART, I²C, and CSI (Renesas' SPI-compatible interface) with up to 4 UART channels, 10 I²C channels, and 8 CSI channels. UART peripherals include built-in LIN 2.2 support-enabling break detection, sync field handling, and checksum calculation-making the R5F101FEDFP#30 suitable for automotive body electronics and industrial LIN networks.
What low-power modes are available on the R5F101FEDFP#30, and what is the minimum current draw?
The R5F101FEDFP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-a critical specification for battery-operated devices. HALT mode consumes 66 μA/MHz, and SNOOZE enables peripheral operation (e.g., ADC conversion) while CPU remains halted, all managed via dedicated control registers in the R5F101FEDFP#30.
