Product details
Overview
R5F100GLDFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and industrial-grade operation from −40°C to +105°C. It integrates 16-bit timers (12 channels), 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, DMA, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100GLDFB#10 datasheet, R5F100GLDFB#10 pinout, R5F100GLDFB#10 application, or R5F100GLDFB#10 equivalent, key selection criteria include its G-grade temperature rating, integrated data flash for parameter storage, low-power real-time control capability, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100GLDFB#10 implements the RL78 CPU core with a 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-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 12-channel 16-bit timer array with input capture/compare, 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and three independent serial interface types-CSI (SPI-compatible), UART/LIN, and I²C-each configurable across multiple channels with shared pins managed via peripheral enable registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLAFB#V0 | Same 128 KB flash, 8 KB data flash, 12 KB RAM, and G-grade temp range, but packaged in 48-pin LQFP (0.8 mm pitch) instead of LFQFP (0.5 mm pitch) | LQFP variant suits legacy PCB layouts with larger pad pitch; LFQFP offers higher I/O density in space-constrained designs | Select R5F100GLAFB#V0 if existing footprint uses 0.8 mm pitch; choose R5F100GLDFB#10 for newer compact layouts requiring finer pitch |
| R5F101GLDFB#10 | Identical package and pinout, but lacks data flash memory (0 KB); retains same 128 KB code flash, 12 KB RAM, and G-grade rating | Suitable where parameter storage is handled externally or not required; lower cost where BGO and flash shielding are unnecessary | Choose R5F101GLDFB#10 only when data flash functionality is excluded from system requirements; verify bootloader and field update strategy accordingly |
Compared with R5F100GLAFB#V0, R5F100GLDFB#10 enables denser PCB layouts via 0.5 mm pitch, while versus R5F101GLDFB#10 it adds critical field-updatable data storage-making it the only choice for applications needing secure, background-capable nonvolatile parameter retention.
