Product details
Overview
R5F100PLAFB#V0 from Renesas is a 100-pin LFQFP (0.5 mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 512 KB flash, 32 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at –40°C to +105°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and hardware multiplier/divider for embedded control in resource-constrained industrial systems.
For engineers reviewing the R5F100PLAFB#V0 datasheet, R5F100PLAFB#V0 pinout, R5F100PLAFB#V0 application, or R5F100PLAFB#V0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, industrial temperature rating (–40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation during program execution, and support for low-power HALT/STOP/SNOOZE modes in battery-backed or thermally demanding environments.
Technical Context
The R5F100PLAFB#V0 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It supports dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed subsystem clock for RTC and watchdog.
Its memory subsystem includes 512 KB code flash (1 KB block size, security lockable), 8 KB data flash with background operation (BGO) and 1,000,000 write endurance, and 32 KB SRAM - with flash library RAM allocation starting at F7F00H. Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, and 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#X0 | Identical silicon and specs; differs only in packaging - embossed tape instead of tray (#V0) | Same industrial temperature grade and peripheral set; intended for automated SMT assembly lines requiring tape-and-reel feed | Select #X0 for high-volume pick-and-place production; #V0 preferred for prototyping and low-volume builds |
| R5F101PLAFB#V0 | Omits 8 KB data flash; retains same 512 KB code flash, 32 KB RAM, and all peripherals except BGO capability | Suitable where firmware updates occur infrequently and parameter storage is handled externally or via code flash emulation | Choose R5F101PLAFB#V0 when data logging or field calibration is unnecessary - reduces cost and simplifies qualification |
Compared with R5F100PLAFB#V0, the #X0 variant offers identical electrical and thermal performance but optimized logistics for volume manufacturing, while R5F101PLAFB#V0 removes data flash to lower unit cost and simplify firmware architecture - both retain full pin compatibility and industrial temperature support.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100PLAFB#V0?
The R5F100PLAFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This enables deterministic execution of real-time control algorithms, such as field-oriented control for motors or fast-response sensor fusion, while maintaining ultra-low power consumption of 66 μA per MHz in active mode. The RL78 core's 3-stage pipeline and variable instruction timing support both high-speed computation and ultra-low-speed RTC operation.
Does the R5F100PLAFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100PLAFB#V0 supports full in-system programming via its on-chip debug interface and self-programming capabilities. It includes boot swap functionality, flash shield window protection, and block-level erase/write prohibition to prevent unauthorized modification. Firmware updates can be performed over UART or other serial interfaces using Renesas-provided flash libraries that allocate RAM at F7F00H for safe reprogramming.
How does the data flash memory in the R5F100PLAFB#V0 differ from standard code flash?
The R5F100PLAFB#V0 includes 8 KB of dedicated data flash memory separate from its 512 KB code flash. Unlike code flash, this data flash supports background operation (BGO), allowing program execution to continue uninterrupted during write/erase cycles. It is rated for 1,000,000 write cycles at VDD = 1.8–5.5 V and is used for parameter storage, calibration data, and firmware logs - with built-in wear leveling handled by the flash library.
What industrial temperature grades are supported by the R5F100PLAFB#V0?
The R5F100PLAFB#V0 is specified for industrial operation from –40°C to +105°C (G-grade), validated across the full range for all peripherals including ADC, RTC, and oscillators. This makes it suitable for deployment in harsh environments such as motor drives, outdoor energy infrastructure, and factory-floor automation equipment where ambient temperatures exceed standard commercial limits.
Can the R5F100PLAFB#V0 operate from a single 3.3 V supply while supporting 5 V-tolerant I/O?
Yes, the R5F100PLAFB#V0 operates from a single supply between 1.6 V and 5.5 V, so a 3.3 V rail is fully supported. Its I/O ports include up to 25 pins with EVDD withstand voltage - meaning they tolerate up to 5.5 V regardless of VDD level. This allows direct interfacing with 5 V sensors, logic, or communication transceivers without level shifters, simplifying system design in mixed-voltage industrial applications.
