Product details
Overview
R5F104LEAFP#V0 from Renesas is a 48 KB flash, 5.5 KB RAM RL78/G14 16-bit microcontroller in 44-pin LQFP package, operating from 1.6–5.5 V with 66 μA/MHz active current and 0.60 μA RTC+LVD standby mode, used in battery-powered industrial sensor nodes and low-power HMI control panels.
For engineers reviewing the R5F104LEAFP#V0 datasheet, R5F104LEAFP#V0 pinout, R5F104LEAFP#V0 application, or R5F104LEAFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch footprint, 48 KB code flash with data flash shield window, integrated 10-bit 20-channel ADC, and support for LIN-bus UART and hardware DTC for deterministic peripheral data movement.
Technical Context
The R5F104LEAFP#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes on-chip debug, self-programming with boot swap, and background operation for data flash writes.
It integrates dual clock domains: high-speed on-chip oscillator (selectable from 1–64 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz), enabling precise real-time clock calendar (99-year), interval timer, and watchdog timer operation independent of main CPU activity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LEAFP#X0 | Identical silicon; differs only in packaging specification (embossed tape vs. tray) | No functional or electrical difference; same pinout, timing, and firmware compatibility | Select #X0 for automated SMT line feed; #V0 for manual or small-batch assembly |
| R5F104LEAFB#V0 | Same core, memory, and peripherals; 48-pin LFQFP (0.5 mm pitch) instead of 44-pin LQFP (0.8 mm pitch) | Requires PCB redesign due to different footprint, pitch, and pin count (48 vs. 44); higher I/O count available | Choose only if additional GPIO, ADC channels, or UARTs are needed; not drop-in compatible |
Compared with R5F104LEAFP#X0, the #V0 variant offers identical functionality with tray packaging optimized for prototyping and low-volume production; versus R5F104LEAFB#V0, it provides a smaller 44-pin LQFP footprint with reduced board area but fewer I/O resources.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F104LEAFP#V0?
The R5F104LEAFP#V0 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. The high-speed on-chip oscillator supports 1–64 MHz selection with ±1.0% accuracy across 1.8–5.5 V and -20 to +85°C.
Does the R5F104LEAFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104LEAFP#V0 supports full in-system programming via TOOL0 pin using Renesas Flash Programmer. It includes boot swap functionality, flash shield window protection, and block erase prohibition to prevent unauthorized rewriting - all essential for secure field firmware updates in the R5F104LEAFP#V0.
How many ADC channels does the R5F104LEAFP#V0 provide, and what reference options are available?
The R5F104LEAFP#V0 integrates a 10-bit successive-approximation ADC with up to 20 input channels. It supports external reference (AVREFP/AVREFM), internal 1.45 V reference, and VDD-based measurement. The ADC operates across the full 1.6–5.5 V supply range, enabling direct sensing of 3.3 V or 5 V sensor outputs in the R5F104LEAFP#V0.
What UART features make the R5F104LEAFP#V0 suitable for LIN-bus automotive applications?
The R5F104LEAFP#V0 includes three UART channels with LIN-specific hardware: automatic sync-break detection, checksum generation (classic and enhanced), and wakeup-on-break capability. These features comply with ISO 17987-4 and eliminate software overhead for LIN frame handling - a key advantage for body electronics modules using the R5F104LEAFP#V0.
Is the R5F104LEAFP#V0 pin-compatible with other RL78/G14 variants like R5F104LEAFB#V0?
No, the R5F104LEAFP#V0 (44-pin LQFP) is not pin-compatible with R5F104LEAFB#V0 (48-pin LFQFP). They differ in pin count, pitch (0.8 mm vs. 0.5 mm), physical dimensions, and I/O mapping. Migration requires PCB redesign. However, the R5F104LEAFP#V0 is fully software-compatible with all RL78/G14 family members sharing the same memory configuration.
