Product details
Overview
R5F100PFAFB#10 from Renesas is a 100-pin LFQFP (0.5-mm pitch), 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100PFAFB#10 datasheet, R5F100PFAFB#10 pinout, R5F100PFAFB#10 application, or R5F100PFAFB#10 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D-grade), on-chip debug support, self-programmable flash with boot swap, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100PFAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual power domains enabling independent control of peripheral clocks and supports HALT/STOP/SNOOZE low-power modes.
Its memory subsystem includes 128 KB code flash (1 KB block size, security-protected erase/write), 8 KB data flash with background operation (BGO) and 1M-cycle endurance, and 12 KB SRAM - with flash library RAM usage starting at FAF00H for J-series packages. The device integrates a 14-level LVD, on-chip POR, and DMA controller with 4 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PGAFB#10 | Same package, same memory (128 KB flash/8 KB data flash/12 KB RAM), identical peripherals - differs only in factory-programmed option bits (e.g., ROM code protection settings). | No functional difference in target applications; suitable for designs requiring alternate security configuration or calibration data preloading. | Select when specific ROM lock bit configuration or factory-trimmed oscillator calibration is required per OEM requirements. |
| R5F101PFAFB#10 | Pin-compatible 100-pin LFQFP variant without data flash (0 KB); retains same CPU, RAM (12 KB), peripherals, and low-power features. | Not suitable for applications requiring nonvolatile parameter storage or firmware update logging; requires external EEPROM or FRAM for persistent data. | Choose for cost-sensitive designs where data flash functionality is unnecessary and external nonvolatile memory is already present. |
Compared with R5F100PFAFB#10, R5F100PGAFB#10 offers identical functionality with differentiated factory settings, while R5F101PFAFB#10 removes data flash to reduce cost - making it viable only when external nonvolatile storage is available and firmware update logging is handled externally.
