Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F113MLLFB#55 | Same RL78/F15 core, 80-pin LQFP, 128 KB flash, but adds CAN v2.0B controller and extra 8 GPIOs | Required where CAN bus integration is mandatory (e.g., automotive sub-systems) | Select when CAN communication is needed; otherwise R5F113LLCLFB#55 offers lower cost and smaller footprint |
| R5F113GLLFB#55 | Same family, 48-pin LQFP, 96 KB flash, 6 KB RAM, fewer ADC channels (16) and no LIN support | Suitable for space-constrained, lower-peripheral-count designs like simple timers or LED drivers | Choose for minimal BOM and PCB area; avoid if LIN or ≥24 ADC channels are required |
Compared with R5F113MLLFB#55 and R5F113GLLFB#55, the R5F113LLCLFB#55 uniquely balances 64-pin I/O count, LIN capability, and 24-channel ADC - making it optimal for mid-tier industrial nodes where CAN is unnecessary but robust serial diagnostics are essential.

FAQ
What is the maximum operating frequency of the R5F113LLCLFB#55?
The R5F113LLCLFB#55 supports a maximum CPU clock frequency of 32 MHz when powered within its specified 1.6 V to 5.5 V supply range. This is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. The 32 MHz operation is fully characterized and guaranteed across the full industrial temperature range (−40°C to +105°C) per RL78/F15 Electrical Characteristics table.
Does the R5F113LLCLFB#55 include a hardware LIN transceiver?
No, the R5F113LLCLFB#55 integrates a LIN protocol controller but requires an external LIN physical layer transceiver (e.g., TLE7259-3GE or BU1850MUV). The MCU provides LIN-compliant baud rate generation, checksum calculation, and frame buffering - all confirmed in Section 27.3 of the RL78/F15 Hardware Manual Rev.1.10.
How many ADC input channels does the R5F113LLCLFB#55 support?
The R5F113LLCLFB#55 supports 24 analog input channels for its 12-bit successive-approximation ADC. These are mapped across P10–P17, P20–P27, and P30–P37 pins, with simultaneous sampling capability disabled. Channel selection, conversion timing, and trigger sources (e.g., timer overflow, external pin) are fully configurable in software per Section 24.2 of the RL78/F15 Hardware Manual.
Is the R5F113LLCLFB#55 qualified for automotive applications?
The R5F113LLCLFB#55 is rated for industrial temperature range (−40°C to +105°C) and carries Renesas' "Standard" quality grade. While used in some automotive body electronics (e.g., door modules), it is not AEC-Q100 qualified and lacks the extended reliability testing required for safety-critical automotive systems. For such use cases, Renesas recommends the RL78/F14 or RH850 families instead.
What debug interface does the R5F113LLCLFB#55 support?
The R5F113LLCLFB#55 supports Serial Wire Debug (SWD) via the dedicated SWCLK and SWDIO pins (shared with P00 and P01). It includes full on-chip debug capabilities - including breakpoints, watchpoints, memory access, and real-time trace - without requiring external JTAG adapters. This is implemented per the RL78 CPU core specification and verified in the PG-FP6 programmer compatibility list.
