Product details
Overview
R5F100JCAFA#V0 from Renesas is a 52-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar function. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100JCAFA#V0 datasheet, R5F100JCAFA#V0 pinout, R5F100JCAFA#V0 application, or R5F100JCAFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, integrated 10-bit ADC (26 channels), dual UART/LIN support, and hardware multiplier/divider for deterministic control loop execution in space-constrained embedded systems.
Technical Context
The R5F100JCAFA#V0 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs min @32 MHz). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and background operation-capable data flash for firmware updates without halting execution.
Its power architecture includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (32 MHz max). The device supports simultaneous peripheral operation-including CSI, I²C, and UART-while maintaining sub-μA retention current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JDAFA#V0 | Same package and memory (256 KB flash, 8 KB data flash, 20 KB RAM), but configured for industrial temperature range (–40°C to +105°C) | Required for HVAC or outdoor equipment operating beyond +85°C ambient | Select when extended temperature qualification is mandatory; otherwise R5F100JCAFA#V0 suffices for standard industrial use |
| R5F101JCAFA#V0 | Identical pinout and package, but lacks data flash memory (0 KB); retains same code flash, RAM, and peripherals | Suitable where firmware updates occur only via external host or where parameter storage uses external EEPROM | Choose to reduce BOM cost when background data rewriting is unnecessary; verify flash library RAM usage compatibility |
