Product details
Overview
R5F100PLDFB#V0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 32 KB RAM, 8 KB data flash, and real-time clock-designed for low-power industrial control, sensor hubs, and smart metering applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100PLDFB#V0 datasheet, R5F100PLDFB#V0 pinout, R5F100PLDFB#V0 application, or R5F100PLDFB#V0 equivalent, key selection criteria include ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), multiple serial interfaces (UART/LIN, I²C, CSI), and hardware multiplier/divider for deterministic control loops.
Technical Context
The R5F100PLDFB#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 features a unified 1 MB address space with four register banks. It integrates on-chip debug, self-programming flash with boot swap, and background operation for data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes; a 14-level LVD with interrupt/reset capability; and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz). The device supports DMA (4 channels), 16-bit timers (16 channels), and a calendar-mode RTC with alarm and correction functions.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100PLDFB#V0?
The R5F100PLDFB#V0 operates up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core efficiency under standard conditions (VDD = 2.7–5.5 V, TA = −40°C to +105°C), and is validated in Renesas Application Note R01AN1403. The R5F100PLDFB#V0 achieves this using its 3-stage pipeline and optimized instruction set without requiring external acceleration.
Does the R5F100PLDFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100PLDFB#V0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for secure firmware updates. Its self-programming capability-combined with boot swap function-enables fail-safe dual-bank updates. The R5F100PLDFB#V0 implements these functions per Renesas Flash Self-Programming Library documentation (R20UT2944), with RAM usage starting at address F7F00H.
What are the supported serial communication interfaces on the R5F100PLDFB#V0, and how many channels are available?
The R5F100PLDFB#V0 supports three serial interface types: UART/LIN (4 channels), I²C/Simplified I²C (10 channels), and CSI (8 channels). All are independently configurable and share no fixed pin conflicts-enabling simultaneous use of UART for debugging, I²C for sensor reading, and CSI for display driving. This configuration is confirmed in the RL78/G13 datasheet section 1.1 "Serial interface" and pin function table for 100-pin LFQFP.
How does the R5F100PLDFB#V0 manage ultra-low power consumption in STOP mode?
The R5F100PLDFB#V0 achieves 0.57 μA in STOP mode by disabling the main clock, CPU, and most peripherals while retaining power to the RTC, LVD circuit, and RAM retention. Wake-up is supported via external interrupt, RTC alarm, or LVD threshold crossing. This specification is measured at VDD = 3.0 V and TA = 25°C per R01DS0131EJ0380 Rev.3.80, and applies identically to the R5F100PLDFB#V0 due to its G-grade industrial qualification.
Is the R5F100PLDFB#V0 pin-compatible with other RL78/G13 100-pin variants such as R5F100PLAFB#V0 or R5F101PLDFB#V0?
The R5F100PLDFB#V0 shares identical 100-pin LFQFP mechanical dimensions and pinout with all RL78/G13 100-pin devices-including R5F100PLAFB#V0 (512 KB flash, no data flash) and R5F101PLDFB#V0 (no data flash). Pin compatibility is guaranteed per Renesas package drawing PLQP0100KE-A and functional pin mapping in Section 1.3 of R01DS0131EJ0380. However, differences in flash configuration require software validation during migration.
