Product details
Overview
R5F100LEDFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 48 KB flash, 3 KB RAM, 4 KB data flash RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes - deployed in industrial motor control and sensor interface modules requiring RTC, 10-bit ADC (26 channels), and LIN-capable UART.
For engineers reviewing the R5F100LEDFB#30 datasheet, R5F100LEDFB#30 pinout, R5F100LEDFB#30 application, or R5F100LEDFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated 12-bit interval timer + real-time clock with calendar/alarm, 2-channel DMA, and support for background data flash rewriting at VDD = 1.8–5.5 V.
Technical Context
The R5F100LEDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and dedicated low-speed oscillator for watchdog operation.
It supports simultaneous peripheral operation including up to 16× 16-bit timers, 3× I²C interfaces, 4× UART/LIN channels, and 2–8× CSI (SPI-compatible) channels - all configurable via register-based control 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 |
|---|---|---|---|
| R5F100LEAFB#30 | Same core, package, and memory size but rated for –40°C to +85°C (A-grade) instead of –40°C to +105°C (G-grade); lacks extended temperature qualification. | Suitable for consumer appliances but not industrial enclosures with high ambient heat. | Select R5F100LEDFB#30 when operating above 85°C ambient or requiring full industrial temperature certification per AEC-Q100 stress test alignment. |
| R5F101LEDFB#30 | Identical package and pinout but omits data flash memory; retains 48 KB code flash and same peripherals except data flash-related registers and BGO functionality. | Applicable where firmware parameters are stored externally or infrequently updated - reduces cost where EEPROM or external flash is already present. | Choose R5F100LEDFB#30 when in-field calibration data, metering logs, or OTA configuration storage must reside on-chip with guaranteed 1M rewrite endurance. |
Compared with R5F100LEAFB#30 and R5F101LEDFB#30, the R5F100LEDFB#30 uniquely combines G-grade temperature rating, integrated 4 KB data flash with background operation, and full peripheral set - making it the only option for thermally demanding industrial applications requiring robust, self-contained nonvolatile parameter storage.

FAQ
What is the maximum operating temperature specification for the R5F100LEDFB#30?
The R5F100LEDFB#30 is qualified for industrial operation from –40°C to +105°C (G-grade), verified per Renesas' standard reliability testing protocols. This rating applies to the full functional specification including ADC accuracy, flash write endurance, and real-time clock stability - confirmed in the R01DS0131EJ0380 datasheet Section 1.1 under "Operating ambient temperature".
Does the R5F100LEDFB#30 support in-system programming via its UART interface?
Yes, the R5F100LEDFB#30 supports bootloader-based in-system programming via UART using Renesas' standard Flash Development Toolkit (FDT) protocol. The device includes on-chip debug circuitry and ROM-resident bootloader that accepts commands over UART pins P12 (TXD0) and P11 (RXD0) - no external programmer required for field firmware updates.
How many I²C interfaces does the R5F100LEDFB#30 provide, and are they hardware or software implemented?
The R5F100LEDFB#30 provides three hardware I²C interfaces (IIC0, IIC1, IIC2), each with dedicated SCL/SDA pins and full master/slave arbitration support. These are implemented in silicon with automatic START/STOP/ACK generation and clock stretching - not bit-banged - ensuring reliable communication at up to 400 kHz standard mode.
Can the R5F100LEDFB#30 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F100LEDFB#30 operates from 1.6 V to 5.5 V. At 1.8 V, all core functions remain active including CPU, 48 KB flash, 3 KB RAM, 10-bit ADC (with internal 1.45 V reference), RTC, 16-bit timers, and UART/LIN - though maximum frequency is reduced to 16 MHz per the voltage/frequency curve in Section 2.2 of the datasheet.
Is the R5F100LEDFB#30 pin-compatible with other RL78/G13 devices in the 64-pin LFQFP package?
Yes, all RL78/G13 64-pin LFQFP variants - including R5F100LEDFB#30, R5F100LDAFB#30, and R5F101LEDFB#30 - share identical pinouts and mechanical footprint. Functional differences (e.g., data flash presence, temperature grade) do not affect signal mapping, enabling drop-in replacement during design iteration or qualification.
