Product details
Overview
R5F100LJDFB#X0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 256 KB flash, 8 KB data flash, 20 KB RAM, 52 I/O pins, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and 16-bit timers - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LJDFB#X0 datasheet, R5F100LJDFB#X0 pinout, R5F100LJDFB#X0 application, or R5F100LJDFB#X0 equivalent, key selection criteria include its -40°C to +105°C operation (G-grade), ultra-low-power STOP mode (0.57 μA), 32 MHz max CPU speed, on-chip debug support, and self-programmable flash with boot swap capability.
Technical Context
The R5F100LJDFB#X0 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). It integrates a DMA controller (4 channels), multiplier/divider unit, and BCD correction circuit for embedded control tasks requiring deterministic timing and arithmetic efficiency.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE low-power modes, and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable). The device supports background operation (BGO) during data flash rewriting and uses dedicated RAM areas (e.g., FAF00H start address) for flash library execution.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LJDFB#X0?
The R5F100LJDFB#X0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core features a 3-stage pipeline and supports variable instruction execution times - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode. This enables precise timing control in motor drives and responsive real-time behavior in HMI applications, all while maintaining the R5F100LJDFB#X0's ultra-low-power architecture.
Does the R5F100LJDFB#X0 include on-chip debug capability and what interfaces does it support?
Yes, the R5F100LJDFB#X0 includes full on-chip debug functionality compatible with Renesas E2 emulator and CS+ IDE. It supports single-wire debug (SWD) via the TOOLx pins and provides breakpoints, watchpoints, and real-time trace. The R5F100LJDFB#X0 also enables flash programming and verification through the debug interface, eliminating the need for external programmers during development and field updates - critical for rapid prototyping and maintenance of deployed R5F100LJDFB#X0-based systems.
How much data flash does the R5F100LJDFB#X0 provide and what are its endurance specifications?
The R5F100LJDFB#X0 integrates 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. It supports background operation (BGO), allowing CPU code execution from main flash while data flash is being rewritten. The R5F100LJDFB#X0 allocates RAM starting at address FAF00H for flash library routines - enabling robust, interrupt-safe firmware updates and parameter storage without system interruption.
What low-power modes are available on the R5F100LJDFB#X0 and what is the lowest achievable current draw?
The R5F100LJDFB#X0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw - ideal for battery-backed timekeeping and wake-on-event applications. HALT mode consumes 66 μA/MHz, and SNOOZE enables peripheral-triggered wake-up with minimal latency. All modes retain RAM content and allow fast resume, making the R5F100LJDFB#X0 suitable for energy-harvesting and long-life portable devices.
Is the R5F100LJDFB#X0 pin-compatible with other RL78/G13 variants and what package does it use?
Yes, the R5F100LJDFB#X0 uses a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch) package with pinout compatibility across the RL78/G13 64-pin family - including R5F100LJAFP#V0 (LQFP-64) and R5F100LJABG#U0 (VFBGA-64). However, mechanical and thermal characteristics differ between packages; the R5F100LJDFB#X0's LFQFP variant offers superior manufacturability in standard SMT lines and enhanced thermal dissipation versus smaller-footprint alternatives - confirming its suitability for high-volume industrial R5F100LJDFB#X0 deployments.
