Product details
Overview
R5F104BEAFP#30 from Renesas is a 32-bit RL78/G14 microcontroller with 48 KB flash, 5.5 KB RAM, and 32-pin LQFP-0.8 mm package, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D), featuring 16-bit timers, 10-bit ADC (8 channels), UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP modes for battery-powered sensor nodes and industrial control units.
For engineers reviewing the R5F104BEAFP#30 datasheet, R5F104BEAFP#30 pinout, R5F104BEAFP#30 application, or R5F104BEAFP#30 equivalent, key selection criteria include its 48 KB code flash size, 32-pin LQFP-0.8 mm footprint, integrated RTC and LVD, 66 μA/MHz active current, and support for LIN-bus-capable UART channels in industrial temperature-grade packaging.
Technical Context
The R5F104BEAFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz). It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus dual UART channels supporting LIN bus protocol.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, and three low-power modes (HALT, STOP, SNOOZE) enabling operation down to 0.60 μA with RTC+LVD active. The device supports background data flash rewriting (BGO) and self-programming with boot swapping.

Applications
| Industrial Sensor Node | Smart Thermostat Controller |
|---|---|
|
Use Scenario: Battery-powered wireless temperature/humidity node with local display and BLE gateway interface. IC Role / Device Role / Timing Role: Main system controller managing ADC sampling, RTC-based wake scheduling, UART-to-BLE bridge, and low-power state transitions. Use Value: 0.60 μA STOP mode with RTC enables multi-year battery life; integrated LVD prevents brown-out corruption during voltage sag. |
Use Scenario: Residential HVAC control unit requiring precise ambient sensing, user interface, and communication with central hub. IC Role / Device Role / Timing Role: Central MCU handling 10-bit ADC readings from NTC thermistors, driving LCD via PCLBUZ outputs, and managing RS-485 Modbus communication. Use Value: On-chip 1.45 V reference ensures stable ADC accuracy across supply voltage drift; 48 KB flash accommodates Modbus stack + UI firmware. |
| Programmable Logic Relay | Motor Control Interface Module |
|
Use Scenario: DIN-rail mounted relay module with configurable I/O, time-delay logic, and serial configuration port. IC Role / Device Role / Timing Role: Real-time I/O sequencer using TAU timers for precise ON/OFF delays and event-triggered outputs. Use Value: Eight 16-bit TAU channels enable independent timing of up to eight relay outputs; SNOOZE mode reduces idle power without losing event responsiveness. |
Use Scenario: Brushless DC motor driver board requiring hall-sensor input decoding, PWM generation, and fault reporting. IC Role / Device Role / Timing Role: Peripheral coordinator interfacing hall sensors (via P00–P01), generating complementary PWM (via TAU), and communicating faults via UART to host MCU. Use Value: Hardware event linking (ELC) routes hall-edge events directly to timer start/stop - eliminates software latency in commutation timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104CEAFP#30 | 64 KB flash, 5.5 KB RAM, same 32-pin LQFP-0.8 mm package and peripheral set | Supports larger firmware images (e.g., OTA update stack + full Modbus RTU) | Select when future firmware growth requires >48 KB code space without PCB change |
| R5F104BDASP#30 | 48 KB flash, 4 KB RAM, 30-pin LSSOP-0.65 mm package, identical core/peripherals | Lower pin count suits space-constrained designs but reduces GPIO count by 2 | Choose for compact PCB layouts where 2 fewer I/O pins are acceptable and thermal dissipation is lower |
Compared with R5F104BEAFP#30, R5F104CEAFP#30 offers headroom for feature-rich firmware while maintaining pin compatibility, whereas R5F104BDASP#30 trades package size and I/O count for reduced board area - both require no schematic redesign but differ in memory scalability and footprint constraints.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104BEAFP#30?
The R5F104BEAFP#30 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA when RTC and LVD remain active - verified in the R01DS0053EJ0370 datasheet Section 1.1.
Does the R5F104BEAFP#30 support LIN bus communication, and which UART channel implements it?
Yes, the R5F104BEAFP#30 supports LIN bus communication via UART2 (pins P13/TxD2 and P14/RxD2), which includes hardware-level sync-break detection and configurable baud rate generation compliant with ISO 17987-4. This capability is confirmed in Section 1.1 "Serial Interfaces" of the R01DS0053EJ0370 datasheet.
What are the flash memory organization and security features of the R5F104BEAFP#30?
The R5F104BEAFP#30 contains 48 KB of code flash organized in 1 KB blocks, with hardware-enforced prohibition of block erase and rewriting to prevent unauthorized firmware modification. It also supports flash shield window protection and on-chip debug lock - all detailed in Section 1.1 "Code Flash Memory" of the R01DS0053EJ0370 datasheet.
Can the R5F104BEAFP#30 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F104BEAFP#30 supports VDD = 1.6–5.5 V, including stable operation at 1.8 V. At this voltage, the 10-bit ADC (with internal 1.45 V reference), RTC, LVD, and all 16-bit timers function fully. However, high-speed on-chip oscillator accuracy degrades slightly beyond ±2.0% - specified in Table 1.2 of R01DS0053EJ0370.
What development tools are officially supported for the R5F104BEAFP#30?
Renesas provides official support for the R5F104BEAFP#30 via CS+ IDE with E1/E20 emulators, Renesas Flash Programmer (RFP), and the RL78/G14 Target Board (YRDKRL78G14). These tools enable full debugging, flash programming, and peripheral register configuration - documented in Renesas Application Note R01AN2379.
