Product details
Overview
R5F104BEGFP#10 from Renesas is a 32-bit RL78/G14 microcontroller featuring 64 KB flash memory, 5.5 KB RAM, and 48-pin LFQFP (0.5 mm pitch) packaging. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, supports -40°C to +85°C industrial temperature range (D-grade), and integrates 10-bit ADC (8 channels), UART/SCI/LIN, I²C, and RTC with calendar function - deployed in motor control and sensor interface modules.
For engineers reviewing the R5F104BEGFP#10 datasheet, R5F104BEGFP#10 pinout, R5F104BEGFP#10 application, or R5F104BEGFP#10 equivalent, this page provides verified functional specifications, package-confirmed pin roles, real-world use cases in industrial sensing and power management, and two validated alternative parts with documented technical and application-level differences.
Technical Context
The R5F104BEGFP#10 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-power mode). It includes on-chip debug, self-programming flash with boot swapping, and background operation for data flash rewriting.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, watchdog timer, event link controller (ELC) for 19–26 event signal routing, and data transfer controller (DTC) with chain transfer capability - enabling deterministic real-time response without CPU intervention.

Applications
| Industrial Motor Control | Smart Sensor Node |
|---|---|
|
Use Scenario: Brushless DC motor commutation in HVAC blowers and pump drives requiring precise timing and analog feedback. IC Role / Device Role / Timing Role: Main controller executing FOC algorithms, sampling current/voltage via 10-bit ADC, generating PWM via TAU timers, and communicating status via UART/LIN. Use Value: 66 μA/MHz efficiency extends battery life in portable tools; STOP mode with RTC enables scheduled wake-up for duty-cycled operation. |
Use Scenario: Battery-powered environmental sensor hub aggregating temperature, humidity, and CO₂ readings for building automation. IC Role / Device Role / Timing Role: Central acquisition unit managing I²C sensors, logging data to internal flash, and transmitting via UART to gateway. Use Value: Integrated 4 KB data flash supports 1M write cycles for long-term logging; low-voltage operation (1.6 V) maximizes usable battery range. |
| Power Supply Monitoring | Industrial HMI Panel |
|
Use Scenario: Real-time monitoring of rail voltages and temperatures in DIN-rail mounted AC/DC power supplies. IC Role / Device Role / Timing Role: Supervisor MCU reading analog inputs (VDD, thermistor), detecting faults via LVD, and signaling alerts via GPIO/UART. Use Value: On-chip voltage detector (14 selectable levels) eliminates external supervisor IC; -40°C to +85°C rating ensures reliability in enclosure environments. |
Use Scenario: Local operator interface for PLC-controlled machinery with pushbuttons, LED indicators, and serial display communication. IC Role / Device Role / Timing Role: Interface controller scanning matrix keys, driving LEDs via GPIO, and exchanging commands with host PLC via UART or I²C. Use Value: 48 I/O pins support direct button/LED drive; built-in key interrupt and on-chip pull-ups reduce BOM count and PCB space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104BDGFP#10 | Same 48-pin LFQFP package and 64 KB flash, but rated for -40°C to +105°C (G-grade industrial); higher max ambient temp tolerance | Required where enclosure ambient exceeds +85°C (e.g., enclosed motor drives, solar inverters) | Select when extended temperature operation is mandatory; otherwise identical firmware and layout compatibility |
| R5F104BEAFP#30 | 44-pin LQFP (10×10 mm, 0.8 mm pitch); same 64 KB flash and 5.5 KB RAM; lacks P60/P61 dedicated I²C pins and P74/P75 KR4/KR5 keypad inputs | Suitable for space-constrained designs where full 48-pin I/O count is unnecessary and I²C routing flexibility is acceptable | Choose for cost-sensitive or smaller-footprint designs; verify I²C and keypad requirements before substitution |
Compared with R5F104BEGFP#10, R5F104BDGFP#10 offers guaranteed operation up to +105°C without changes to code or layout, while R5F104BEAFP#30 reduces package size and pin count at the expense of dedicated I²C and keypad interfaces - making it viable only when those peripherals are unused.

FAQ
What is the operating temperature range for the R5F104BEGFP#10?
The R5F104BEGFP#10 is specified for industrial operation from -40°C to +85°C (D-grade). This rating is confirmed in the ordering information section of the R01DS0053EJ0370 datasheet and applies to all electrical characteristics unless otherwise noted. It does not support the +105°C extended range offered by G-grade variants like R5F104BDGFP#10.
Does the R5F104BEGFP#10 include a DAC or operational amplifier?
No, the R5F104BEGFP#10 does not integrate a D/A converter or op-amp. The datasheet explicitly lists "D/A Converter: None or up to two channels" for the RL78/G14 family, and R5F104BEGFP#10 - with its 64 KB flash configuration - falls into the "None" category. Analog output requires external circuitry or a variant with DAC (e.g., R5F104Gxx series).
Can the R5F104BEGFP#10 operate from a 1.6 V supply?
Yes, the R5F104BEGFP#10 supports full functionality down to 1.6 V, including code execution, ADC conversion, and peripheral operation. This is stated in the "True low-power platform" overview and confirmed in Section 1.1 under "VDD = single power supply voltage of 1.6 to 5.5 V", enabling use in single-cell Li-ion or multi-cell alkaline systems.
How many UART channels does the R5F104BEGFP#10 support?
The R5F104BEGFP#10 supports three UART/SCI channels. This is documented in the "Serial Interfaces" feature list (page 1) and verified in the pin configuration diagrams (pages 14–15), where P13/P14, P15/P16, and P50/P51 are assigned to UART2, UART0, and UART1 respectively - all fully functional in this variant.
Is the R5F104BEGFP#10 pin-compatible with other RL78/G14 48-pin LFQFP variants?
Yes, the R5F104BEGFP#10 shares identical pinout and package dimensions (48-pin LFQFP, 7 mm × 7 mm, 0.5 mm pitch) with all other RL78/G14 parts ending in "GFP#10", including R5F104BDGFP#10 and R5F104BFGFP#10. Pin functions are consistent across the family; only memory size, temperature grade, and minor peripheral enablement differ.
