Product details
Overview
R5F100FJAFP#X0 from Renesas is a 44-pin LQFP-44, 1.6–5.5 V, 96 KB flash, 8 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller with integrated RTC, 10-bit ADC (12-channel), UART/SPI/I²C interfaces, and ultra-low-power operation (66 μA/MHz active, 0.57 μA in RTC+LVD mode), deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100FJAFP#X0 datasheet, R5F100FJAFP#X0 pinout, R5F100FJAFP#X0 application, or R5F100FJAFP#X0 equivalent, key selection criteria include its 44-pin LQFP package, 96 KB code flash with self-programming support, 12-channel 10-bit ADC, real-time clock with calendar/alarm, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100FJAFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz), and features an on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable). It integrates dual power domains enabling independent RTC/LVD operation during deep sleep.
Its peripheral set includes up to 4 UART channels (LIN-capable), 10 I²C/Simplified I²C channels, 8 CSI/SPI channels, 16× 16-bit timers, 12-bit interval timer, watchdog timer, DMA controller (4 channels), and hardware multiplier/divider - all optimized for deterministic real-time control in resource-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and low-code-footprint firmware for cost-sensitive control applications. |
| Flash Memory | 96 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for robust firmware/data logging. |
| RAM | 4 KB on-chip RAM; sufficient for real-time task stacks, ISR context, and small buffer handling without external memory. |
| ADC | 10-bit resolution, 12 analog input channels, internal 1.45 V reference; suitable for precision analog sensing in HVAC and industrial monitoring. |
| Power Consumption | 66 μA/MHz active current; 0.57 μA in STOP mode with RTC + LVD active; extends battery life in wireless sensor endpoints. |
| Operating Voltage | 1.6 V to 5.5 V single supply; eliminates need for external voltage regulators in multi-rail systems or legacy 5 V designs. |
| Temperature Range | −40°C to +85°C (Industrial Grade A); qualified for deployment in factory automation and building control environments. |
Pinout & Package
Package: 44-pin LQFP (10 × 10 mm, 0.8-mm pitch), RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
