Product details
Overview
R5F100PLAFB#X0 from Renesas is a 100-pin LFQFP (14 × 14 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 32 KB RAM, and 8 KB data flash-operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz, and supporting ultra-low-power modes (0.57 μA RTC+LVD). It targets battery-powered industrial control, sensor hubs, and smart metering.
For engineers reviewing the R5F100PLAFB#X0 datasheet, R5F100PLAFB#X0 pinout, R5F100PLAFB#X0 application, or R5F100PLAFB#X0 equivalent, key selection criteria include its integrated real-time clock with calendar/alarm, 26-channel 10-bit ADC, 16-channel 16-bit timer suite, and support for LIN-bus UART-critical for deterministic low-power embedded control in harsh environments.
Technical Context
The R5F100PLAFB#X0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic performance/power trade-offs. Its memory subsystem includes 512 KB code flash (1 KB blocks), 8 KB background-operable data flash (1M rewrite cycles), and 32 KB on-chip RAM.
Peripheral integration centers on mixed-signal control: dual 16-bit timer arrays (16 channels total), 12-bit interval timer, hardware RTC with calendar and correction, 3× I²C/Simplified I²C interfaces, 4× UART/LIN channels, and 2× CSI (SPI-compatible) interfaces-all accessible via 80 general-purpose I/O pins with N-ch open-drain, TTL input, and pull-up options.

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#V0 | Identical silicon, but supplied in tray packaging instead of embossed tape; same LFQFP-100 package, 512 KB flash, and −40°C to +105°C rating. | No functional difference; selected when customers require tray-based SMT line feeding or manual prototyping. | Choose #V0 for low-volume evaluation or small-batch production where tape-and-reel handling is impractical. |
| R5F101PLAFB#X0 | Same package and pinout, but lacks data flash memory (0 KB vs. 8 KB); retains all other peripherals including RTC, ADC, and timers. | Suitable for applications requiring only code storage and no field-updatable parameter storage (e.g., fixed-function controllers). | Select #X0 variant when firmware-only updates suffice and data logging or calibration storage is handled externally. |
Compared with R5F100PLAFB#X0, the #V0 offers identical functionality with tray packaging for flexibility in assembly logistics, while the R5F101PLAFB#X0 removes data flash to reduce cost and simplify qualification-making it viable where non-volatile parameter storage is unnecessary.

The R5F100PLAFB#X0 operates from a single 1.6 V to 5.5 V supply and supports three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power background ADC conversion). These modes are controlled via software and enable optimized energy use across diverse operational states.
How much user-accessible RAM and flash memory does the R5F100PLAFB#X0 provide?
The R5F100PLAFB#X0 integrates 32 KB of on-chip RAM for program execution and data storage, plus 512 KB of code flash memory organized in 1 KB blocks. It also includes 8 KB of dedicated data flash memory with background operation capability and 1 million write/erase cycle endurance.
