Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104CEAFP#10 | 64 KB flash, 5.5 KB RAM, same 44-pin LQFP-0.8 mm package and peripheral set | Supports larger firmware images (e.g., with embedded web server or advanced encryption) | Select when future firmware growth or security libraries require >48 KB code space |
| R5F104BEAFB#10 | Identical flash/RAM/peripherals; differs only in 48-pin LFQFP-0.5 mm package (smaller footprint, finer pitch) | Requires PCB redesign due to different pin count, pitch, and thermal pad layout | Select only when board space constraints necessitate 48-pin LFQFP and re-layout is feasible |
Compared with R5F104CEAFP#10, the R5F104BEAFP#10 trades 16 KB flash capacity for identical cost and power profile; compared with R5F104BEAFB#10, it retains legacy LQFP-0.8 mm compatibility but occupies more PCB area-making it optimal for incremental upgrades in existing 44-pin designs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BEAFP#10?
The R5F104BEAFP#10 operates at a maximum frequency of 32 MHz and delivers 44 DMIPS (Dhrystone MIPS) performance. This benchmark reflects its real-world computational throughput for embedded control tasks, validated under typical operating conditions (VDD = 3.3 V, TA = 25°C). The RL78 core's 3-stage pipeline and optimized instruction set enable deterministic execution critical for motor control and real-time sensor processing in the R5F104BEAFP#10.
Does the R5F104BEAFP#10 support LIN bus communication, and how is it implemented?
Yes, the R5F104BEAFP#10 supports LIN bus communication through its UART peripherals, which include LIN-specific features such as automatic sync-break detection, checksum calculation, and slave node response timing control. UART channels (e.g., UART2 on P13/P14) can be configured in LIN mode per the RL78/G14 hardware manual. This native LIN capability eliminates external transceivers in simple slave-node applications and is fully supported in Renesas' e² studio middleware stack for the R5F104BEAFP#10.
What are the memory resources allocated to the R5F104BEAFP#10, and how is data flash used?
The R5F104BEAFP#10 integrates 48 KB of code flash memory and 4 KB of data flash memory, with 5.5 KB of on-chip RAM. Data flash is organized in 1 KB blocks and supports background operation (BGO), allowing program execution from code flash while rewriting data flash-enabling nonvolatile parameter storage (e.g., calibration values, device IDs) without halting application logic. The R5F104BEAFP#10's data flash endurance is rated at 1,000,000 write cycles at VDD = 1.8–5.5 V.
How does the R5F104BEAFP#10 achieve ultra-low power consumption in STOP mode?
The R5F104BEAFP#10 achieves 0.60 μA typical current in STOP mode by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits while disabling the CPU, flash, RAM, and all peripherals except those explicitly enabled for wake-up (e.g., INT0–INT7, RTC alarm). This state preserves calendar time and system safety monitoring while minimizing leakage. The R5F104BEAFP#10's on-chip regulator and optimized process technology ensure this specification holds across the full -40°C to +85°C industrial temperature range.
Is the R5F104BEAFP#10 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
Yes, all RL78/G14 devices in the 44-pin LQFP-0.8 mm package-including R5F104BEAFP#10, R5F104CEAFP#10, and R5F104FEAFP#10-share identical pinouts, electrical characteristics, and mechanical dimensions. This allows direct substitution within the same package family for memory or peripheral scaling (e.g., upgrading from 48 KB to 64 KB flash) without PCB redesign. The R5F104BEAFP#10's pin mapping is fully documented in Section 1.3.5 of the R01DS0053EJ0370 datasheet.
