Product details
Overview
R5F100LJGFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 256 KB flash, 8 KB data flash, 20 KB RAM, 52-channel 10-bit ADC, and real-time clock. It delivers 41 DMIPS at 32 MHz and operates from 1.6 V to 5.5 V, targeting battery-powered industrial sensors and low-power HMI control units.
For engineers reviewing the R5F100LJGFA#30 datasheet, R5F100LJGFA#30 pinout, R5F100LJGFA#30 application, or R5F100LJGFA#30 equivalent, key selection criteria include its ultra-low power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated BCD correction, background data flash rewriting (BGO), and 32-channel I²C/SPI/UART interface support for sensor fusion and serial communication subsystems.
Technical Context
The R5F100LJGFA#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory architecture includes 256 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite endurance, and 20 KB on-chip RAM.
Peripherals include eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, one watchdog timer, and a DMA controller with four channels enabling 2-clock transfers between SFR and RAM. Serial interfaces comprise up to ten I²C/Simplified I²C channels, eight CSI (SPI-compatible) channels, and four UART/LIN channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LJGFA#30 | No data flash memory (0 KB); identical core, peripherals, package, and temperature rating | Not suitable for applications requiring nonvolatile parameter storage or field firmware updates | Select when data logging or configuration persistence is handled externally or not required |
| R5F100LJGFB#30 | Same specs but in 64-pin LFQFP (0.5-mm pitch) instead of LQFP (0.65-mm pitch) | Requires PCB redesign due to different footprint, land pattern, and thermal pad geometry | Choose only if existing board uses LFQFP-0.5mm or requires finer pitch for space-constrained layouts |
Compared with R5F100LJGFA#30, R5F101LJGFA#30 removes data flash to reduce cost and die size while retaining all other functionality-ideal for fixed-function control where parameters are hard-coded. R5F100LJGFB#30 offers identical electrical behavior but demands mechanical redesign due to incompatible pin pitch and thermal pad layout.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LJGFA#30?
The R5F100LJGFA#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This value is measured under standard conditions (VDD = 3.0 V, TA = 25°C) and reflects the RL78 CPU core's optimized 3-stage pipeline execution efficiency at full speed.
Does the R5F100LJGFA#30 support background data flash rewriting (BGO), and what is its endurance specification?
Yes, the R5F100LJGFA#30 supports background data flash rewriting (BGO), allowing program execution from code flash while simultaneously erasing or programming data flash memory. Its data flash endurance is rated at 1,000,000 write/erase cycles (typical), with rewrite voltage supported across the full 1.8 V to 5.5 V VDD range.
What are the key low-power modes available on the R5F100LJGFA#30, and what is the lowest current consumption achievable?
The R5F100LJGFA#30 offers HALT, STOP, and SNOOZE low-power modes. The lowest current consumption is 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active-verified at VDD = 3.0 V and TA = 25°C. This enables multi-year operation in battery-powered applications.
How many analog input channels does the R5F100LJGFA#30 support, and what ADC resolution and reference options are available?
The R5F100LJGFA#30 integrates a 10-bit successive approximation ADC with up to 52 analog input channels. It supports internal 1.45 V reference voltage and temperature sensor inputs, and allows external reference configuration via AVREFP/AVREFM pins for precision measurement applications.
Is the R5F100LJGFA#30 pin-compatible with other RL78/G13 variants in the same 64-pin LQFP package?
Yes, the R5F100LJGFA#30 shares identical pinout and electrical characteristics with other RL78/G13 64-pin LQFP variants (e.g., R5F100LCAFA#30, R5F100LLAFA#30), provided they use the same FA suffix (LQFP-0.65mm) and G-grade temperature rating. Pin compatibility extends to power, reset, clock, and all I/O functions defined in the RL78/G13 pin configuration table.
