Product details
Overview
R5F100LJAFB#30 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating at up to 32 MHz with 41 DMIPS performance and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in industrial sensors and motor drives.
For engineers reviewing the R5F100LJAFB#30 datasheet, R5F100LJAFB#30 pinout, R5F100LJAFB#30 application, or R5F100LJAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm pitch package, 256 KB code flash with self-programming, 10-bit ADC with internal reference, and support for STOP/HALT/SNOOZE low-power modes in -40°C to +105°C industrial environments.
Technical Context
The R5F100LJAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its memory subsystem includes 256 KB on-chip flash with 1 KB block erase, 8 KB data flash supporting background operation (BGO), and 20 KB RAM with dedicated flash library usage at address FAF00H.
Peripheral integration includes dual DMA channels (2 clocks per 8/16-bit SFR↔RAM transfer), hardware multiplier/divider, 16-channel 16-bit timer, calendar-capable RTC, watchdog timer with dedicated low-speed oscillator, and multi-channel serial interfaces (CSI, UART/LIN, I²C) - all designed for deterministic real-time control in resource-constrained industrial nodes.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LJAFB#30?
The R5F100LJAFB#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This is achieved through its RL78 CPU core with 3-stage pipeline and high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C - enabling deterministic real-time control in time-critical applications without external clock components.
Does the R5F100LJAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100LJAFB#30 supports full in-system programming via its on-chip debug interface and self-programming capabilities. It includes boot swap functionality and flash shield window protection to prevent unauthorized access or corruption during over-the-air or field firmware updates - critical for maintaining security and reliability in deployed R5F100LJAFB#30-based systems.
How does the R5F100LJAFB#30 achieve ultra-low power consumption in standby mode?
The R5F100LJAFB#30 achieves 0.57 μA standby current in STOP mode with only RTC and LVD active by disabling the CPU, flash, and most peripherals while retaining real-time calendar functionality and voltage monitoring. This enables decade-long battery operation in sensor nodes - a capability verified in the R01DS0131EJ0380 datasheet under TA = -40°C to +105°C conditions for the G-grade R5F100LJAFB#30.
What analog features are integrated into the R5F100LJAFB#30 for sensor interfacing?
The R5F100LJAFB#30 integrates a 10-bit successive-approximation ADC with 26 input channels, selectable internal 1.45 V reference voltage, and an on-chip temperature sensor. These features allow direct connection of resistive sensors, thermistors, and voltage-output transducers without external signal conditioning - reducing BOM count and PCB area in R5F100LJAFB#30-based measurement systems.
Is the R5F100LJAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LJAFB#30 shares identical 64-pin LFQFP-0.5mm pitch pinout with all other RL78/G13 devices in the FB package variant (e.g., R5F100LCAFB#30, R5F100LLAFB#30), including consistent power, reset, clock, and peripheral pin assignments - enabling hardware reuse across memory and feature variants within the same pin-count family.
