Product details
Overview
R5F101FEDFP#X0 from Renesas is a 44-pin LQFP-44, 96 KB flash, no data flash, industrial-grade RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), used in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101FEDFP#X0 datasheet, R5F101FEDFP#X0 pinout, R5F101FEDFP#X0 application, or R5F101FEDFP#X0 equivalent, key selection criteria include its 96 KB code flash + zero data flash configuration, 44-pin LQFP package with 32 I/Os, integrated RTC and 10-bit ADC (24 channels), and support for LIN-bus UART in industrial temperature range (−40°C to +85°C).
Technical Context
The R5F101FEDFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer using dedicated low-speed oscillator.
It supports multiple serial interfaces including 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and 3–10 I²C/Simplified I²C channels. The 10-bit A/D converter features 24 analog inputs, internal 1.45 V reference, and temperature sensor - all operable across the full 1.6–5.5 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FEDFP#X0 | Same 44-pin LQFP package and 96 KB flash, but includes 4 KB data flash for parameter storage | Required where field-updatable calibration tables or device configuration must persist across power cycles | Select when nonvolatile parameter storage is mandatory; adds ~$0.15 cost and minor firmware overhead for flash management |
| R5F101GEDFP#X0 | Same footprint and no data flash, but upgraded to 128 KB flash and 12 KB RAM | Suitable for applications needing larger firmware image (e.g., OTA bootloader + dual-application partitioning) | Choose for future-proofing or complex protocol stacks (Modbus TCP, BLE HCI); requires validation of increased RAM usage |
Compared with R5F101FEDFP#X0, R5F100FEDFP#X0 adds data flash for persistent settings but increases code complexity, while R5F101GEDFP#X0 trades flash density for scalability - both retain identical pinout, peripheral set, and power profile.

FAQ
Does R5F101FEDFP#X0 include data flash memory?
No, R5F101FEDFP#X0 contains 96 KB of code flash memory and 4 KB of RAM, but zero data flash memory. This distinguishes it from the R5F100x series (e.g., R5F100FEDFP#X0), which integrates 4 KB of data flash for nonvolatile parameter storage. Firmware must use code flash or external EEPROM for configuration persistence.
What is the maximum ambient temperature rating for R5F101FEDFP#X0?
R5F101FEDFP#X0 is rated for industrial operation from −40°C to +85°C, indicated by the "D" in its product family designation per Renesas' part numbering scheme. It does not support the extended −40°C to +105°C range (denoted by "G"), making it suitable for enclosed industrial cabinets but not under-hood automotive environments.
Which serial protocols does R5F101FEDFP#X0 support natively?
R5F101FEDFP#X0 supports UART with LIN-bus physical layer compliance (ISO 17987-4), CSI (SPI-compatible serial interface), and I²C/Simplified I²C - all implemented in hardware with DMA support. It does not include CAN, USB, or Ethernet peripherals. Up to four UART channels can operate concurrently, two of which support LIN auto-wake and sync-break detection.
Can R5F101FEDFP#X0 drive an LCD directly?
Yes, R5F101FEDFP#X0 includes an on-chip LCD controller supporting static and multiplexed (up to 4-backplane) displays. It drives common LCD glass types without external bias generation, using internal charge pump and software-configurable duty/boost settings - confirmed in Section 24.1 of R01DS0131EJ0380.
What debug interface does R5F101FEDFP#X0 use?
R5F101FEDFP#X0 uses Renesas' on-chip debug interface accessible via the single-pin SWD (Serial Wire Debug) protocol through the BKGD pin (P15). It supports full JTAG-style debugging - including breakpoints, watchpoints, and memory inspection - without requiring additional debug headers or dedicated pins beyond the standard reset and BKGD lines.
