Overview
R5F100PLAFB#10 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, 8 KB data flash, 32 KB RAM, and operation from −40°C to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F100PLAFB#10 datasheet, R5F100PLAFB#10 pinout, R5F100PLAFB#10 application, or R5F100PLAFB#10 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, 512 KB code flash with self-programming and flash shield window, 10-bit ADC with internal temperature sensor and 1.45 V reference, and support for SNOOZE/STOP/HALT ultra-low-power modes in extended temperature industrial environments.
Technical Context
The R5F100PLAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, BGO-capable data flash rewriting, and hardware multiplier/divider for embedded control math.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN, and 2–8× CSI (SPI-compatible) interfaces - all configurable via register-based control without external glue logic.

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#30 | Identical silicon, identical specs, but supplied in embossed tape (not tray); same 100-pin LFQFP-0.5mm package and G-grade temp range | No functional difference - intended for automated SMT assembly rather than manual/hand-solder prototyping | Select #30 for high-volume production lines using tape-and-reel feeders; #10 is optimized for tray-based small-batch or evaluation use |
| R5F101PLAFB#10 | Same package and pinout, but lacks data flash memory (0 KB vs. 8 KB); otherwise identical core, peripherals, and power specs | Not suitable for applications requiring nonvolatile parameter storage or firmware-over-the-air update staging | Choose R5F101PLAFB#10 only when data flash is unnecessary - reduces cost and simplifies flash management, but forfeits BGO logging and secure boot swap capability |
Compared with R5F100PLAFB#30, the #10 variant offers tray packaging for flexible handling and evaluation; compared with R5F101PLAFB#10, it retains full 8 KB data flash with background operation - essential for field-upgradable industrial firmware and persistent calibration storage.
