Product details
Overview
R5F100GAAFB#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 RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered sensor nodes and motor control.
For engineers reviewing the R5F100GAAFB#10 datasheet, R5F100GAAFB#10 pinout, R5F100GAAFB#10 application, or R5F100GAAFB#10 equivalent, key selection criteria include its G-grade temperature rating, integrated data flash with 1M rewrite cycles, background operation during program execution, 1.6–5.5 V supply range, and hardware multiplier/divider for real-time control math.
Technical Context
The R5F100GAAFB#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). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with BGO support, and 12 KB SRAM - all accessible under single-supply 1.6–5.5 V operation.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 × 16-bit timers, real-time clock with calendar/alarm/correction, 2–4 channel DMA, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C - all configurable for low-power SNOOZE mode operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCAFB#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., security settings). | No functional difference in target applications; suitable for designs requiring alternate security lock configurations. | Select when specific flash shield window or debug access policy is required per production batch. |
| R5F101GAAFB#10 | Omits data flash (0 KB); retains same core, clock, I/O count, and peripheral set - reduces cost where non-volatile parameter storage is handled externally. | Not suitable for applications requiring embedded data logging or field-updatable calibration tables without external EEPROM. | Choose for cost-sensitive consumer appliances where external SPI flash suffices for configuration storage. |
Compared with R5F100GAAFB#10, R5F100GCAFB#10 offers identical functionality with variant security settings, while R5F101GAAFB#10 removes data flash to lower unit cost - making it viable only when external non-volatile storage replaces on-chip data retention needs.
