Product details
Overview
R5F100LFGFB#30 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 512 KB flash, 8 KB data flash, and 32 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 12-bit ADC (26 channels), and real-time clock with calendar function - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F100LFGFB#30 datasheet, R5F100LFGFB#30 pinout, R5F100LFGFB#30 application, or R5F100LFGFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), 64-pin LFQFP-0.5mm pitch package (FB), integrated data flash with 1M rewrite cycles, background operation during program execution, and hardware multiplier/divider for deterministic control loops.
Technical Context
The R5F100LFGFB#30 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 ultra-low-speed mode). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 3× I²C/Simplified I²C interfaces, 4× UART/LIN channels, 2–8× CSI (SPI-compatible) channels, DMA controller (4 channels), and 12-bit interval timer - all designed for deterministic real-time response in resource-constrained embedded systems without external timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGFB#30 | Same 512 KB flash, 8 KB data flash, 32 KB RAM, but rated for -40°C to +85°C (D-grade) | Lacks extended temperature qualification; unsuitable for under-hood or high-ambient industrial enclosures | Select when cost-sensitive designs operate within standard industrial ambient limits and do not require +105°C certification |
| R5F101LGFB#30 | Identical package and pinout, but no data flash memory (0 KB); retains full code flash and peripheral set | Cannot store field-updatable calibration data or configuration parameters persistently across power cycles | Choose where firmware is static and no runtime parameter storage is needed - reduces BOM cost and simplifies flash management |
Compared with R5F100LFGFB#30, the R5F100LGFB#30 trades extended temperature capability for lower acquisition cost, while the R5F101LGFB#30 removes data flash entirely - enabling simpler firmware architecture but eliminating nonvolatile user data retention capability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LFGFB#30?
The R5F100LFGFB#30 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode using the on-chip oscillator, which is factory-trimmed to ±1.0% accuracy across 1.8–5.5 V and -40°C to +105°C. This enables deterministic real-time control in motor and power conversion applications where cycle count predictability is critical.
Does the R5F100LFGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100LFGFB#30 supports full in-system programming via its on-chip debug interface and includes boot swap functionality for secure firmware updates. The flash shield window prevents unauthorized read-out of code memory, and block-level erase prohibition enhances security. Self-programming routines execute from RAM, allowing safe dual-bank update sequences without halting real-time operations.
How does the data flash memory in the R5F100LFGFB#30 differ from standard code flash in terms of usage and endurance?
The R5F100LFGFB#30 includes 8 KB of dedicated data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. Unlike code flash, it supports background operation (BGO): the CPU can execute instructions from program memory while data flash is being rewritten. This enables seamless runtime parameter storage - such as calibration coefficients or event logs - without interrupting control tasks.
What peripheral interfaces are available on the R5F100LFGFB#30 for connecting to sensors and communication buses?
The R5F100LFGFB#30 provides 4 UART/LIN channels (supporting LIN 2.2 physical layer), 3 I²C/Simplified I²C interfaces, and up to 8 CSI (SPI-compatible) channels. Its 26-channel 10-bit ADC supports direct connection to thermistors, RTDs, and bridge sensors. All serial interfaces feature independent clock sources and programmable baud rates, enabling concurrent sensor polling and host communication in multi-protocol industrial gateways.
Is the R5F100LFGFB#30 pin-compatible with other RL78/G13 variants in the same package footprint?
Yes, the R5F100LFGFB#30 shares identical pinout and electrical characteristics with all other 64-pin LFQFP RL78/G13 devices (e.g., R5F100LGFB#30, R5F101LGFB#30), including identical power, reset, clock, and I/O pin assignments. This allows drop-in substitution between variants differing only in memory size, data flash presence, or temperature grade - simplifying design reuse and qualification across product families.
