Product details
Overview
R5F100GFAFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for low-power industrial control, sensor nodes, and appliance motor management operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100GFAFB#30 datasheet, R5F100GFAFB#30 pinout, R5F100GFAFB#30 application, or R5F100GFAFB#30 equivalent, key selection criteria include ultra-low power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated BGO-capable data flash, 32 MHz max CPU speed, and industrial-grade temperature support up to +105°C.
Technical Context

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGAFA#V0 | Same 128 KB flash/8 KB data flash/12 KB RAM, but 44-pin LQFP (10×10 mm, 0.8 mm pitch); lacks 2 extra ADC channels and 2 GPIO vs. R5F100GFAFB#30 | Lower pin count suits space-constrained designs where fewer analog inputs or peripherals are needed | Select when PCB layout favors larger pitch or reduced I/O count is acceptable |
| R5F101GFAFB#30 | Identical package and pinout, but no data flash (0 KB); retains full 128 KB code flash and same peripheral set | Suitable for cost-sensitive applications where nonvolatile parameter storage is handled externally or not required | Choose when eliminating data flash reduces BOM cost and firmware does not require field-updatable calibration or logs |
