Product details
Overview
R5F104FHAFP#50 from Renesas is a 44-pin LQFP, 128 KB flash, 8 KB data flash, 16 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F104FHAFP#50 datasheet, R5F104FHAFP#50 pinout, R5F104FHAFP#50 application, or R5F104FHAFP#50 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, integrated RTC with calendar/alarm, 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral event handling in resource-constrained embedded control.
Technical Context
The R5F104FHAFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates a configurable Event Link Controller (ELC) linking up to 26 event sources to peripherals without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by interrupts-including chain transfer-enabling efficient background data movement during low-power operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GHAFP#50 | 128 KB flash, same package, but 20 KB RAM (vs. 16 KB) and enhanced DTC/ELC feature set | Better suited for complex state machines with large lookup tables or extended buffer requirements | Select when >16 KB RAM is required for real-time FFT or multi-protocol stacks |
| R5F104FHAFB#50 | Identical memory/peripherals, but 48-pin LFQFP (0.5 mm pitch) instead of 44-pin LQFP (0.8 mm pitch) | Requires PCB redesign; offers 4 additional GPIO and one extra UART channel | Choose only if pin count expansion or finer-pitch assembly capability exists |
Compared with R5F104GHAFP#50, the R5F104FHAFP#50 trades 4 KB RAM for lower BOM cost and identical footprint compatibility with existing 44-pin LQFP layouts; versus R5F104FHAFB#50, it avoids fine-pitch assembly complexity while retaining full peripheral functionality in a more manufacturable package.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104FHAFP#50?
The R5F104FHAFP#50 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 44 DMIPS performance at 66 μA/MHz (2.112 mA total at 32 MHz). In STOP mode with only RTC and LVD active, it draws just 0.60 μA - verified per R01DS0053EJ0370 Rev. 3.70, Section 1.1.
Does the R5F104FHAFP#50 support LIN bus communication, and which UART channel implements it?
Yes, the R5F104FHAFP#50 supports LIN 2.2A protocol via UART2 (pins P13/P14), with hardware-level sync-break detection, checksum generation, and identifier filtering. This capability is confirmed in the "Serial Interfaces" section of R01DS0053EJ0370 Rev. 3.70, Page 1.
How many analog input channels does the R5F104FHAFP#50 ADC support, and what reference voltages are available?
The R5F104FHAFP#50 features a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19). It supports VDD as reference, internal 1.45 V bandgap reference, and external AVREFP/AVREFM differential reference - all specified in Section 1.1 "A/D Converter" of R01DS0053EJ0370 Rev. 3.70.
Is the R5F104FHAFP#50 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
Yes - all RL78/G14 44-pin LQFP variants (e.g., R5F104FAAFP#50, R5F104GHAFP#50) share identical pinout, electrical characteristics, and mechanical footprint per PLQP0044GC-A code. Memory size and peripheral enablement differ, but PCB layout remains interchangeable.
