Product details
Overview
R5F100JCAFA#30 from Renesas is a 52-pin LQFP-0.65mm 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for low-power industrial control, sensor hubs, and smart metering applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100JCAFA#30 datasheet, R5F100JCAFA#30 pinout, R5F100JCAFA#30 application, or R5F100JCAFA#30 equivalent, key selection criteria include ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated data flash with 1M rewrite cycles, and support for LIN-bus UART, I²C, and CSI serial interfaces in an industrial-grade -40°C to +85°C temperature range.
Technical Context
The R5F100JCAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, plus DMA controller (4 channels) and hardware multiplier/divider/accumulator supporting 16×16→32-bit and 32÷32→32-bit operations - all optimized for deterministic real-time response in resource-constrained embedded systems.

The R5F100JCAFA#30 operates up to 32 MHz with a typical active current of 66 μA per MHz. At full speed, this yields ~2.1 mA total active current (excluding peripherals), verified under VDD = 3.3 V and TA = 25°C. Its ultra-low-power STOP mode draws only 0.57 μA when RTC and LVD remain active - critical for battery-backed applications.
Does the R5F100JCAFA#30 support in-system programming and secure firmware updates?
Yes, the R5F100JCAFA#30 supports full in-system programming via on-chip debug interface and includes flash shield window and boot swap functions. These features enable secure field firmware updates with rollback protection and prevent unauthorized access to code flash contents during reprogramming.
How many analog input channels does the R5F100JCAFA#30 provide, and what ADC resolution is supported?
The R5F100JCAFA#30 provides 26 analog input channels with a 10-bit successive-approximation ADC. It supports both single-ended and differential measurement modes, includes an internal 1.45 V reference voltage, and integrates a calibrated temperature sensor usable without external components.
What serial communication interfaces are integrated into the R5F100JCAFA#30?
The R5F100JCAFA#30 integrates up to 8 CSI (SPI-compatible) channels, 4 UART/LIN modules (with hardware LIN 2.2 support), and 10 I²C/Simplified I²C channels. All interfaces are independently configurable and support multi-master arbitration, clock stretching, and automatic baud rate detection.
Is the R5F100JCAFA#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100JCAFA#30 is fully pin-compatible with all 52-pin LQFP RL78/G13 devices (e.g., R5F100JDAFA#30, R5F100JEAFA#30), sharing identical pin mapping, electrical characteristics, and peripheral routing - enabling drop-in replacement for memory or grade variants without PCB redesign.
