Product details
Overview
R5F100LEDFB#50 from Renesas is a 64-pin, LFQFP-0.5mm-pitch, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA for embedded control in battery-powered and space-constrained industrial systems.
For engineers reviewing the R5F100LEDFB#50 datasheet, R5F100LEDFB#50 pinout, R5F100LEDFB#50 application, or R5F100LEDFB#50 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, 64-pin LFQFP package with 0.5 mm pitch, integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency wake-up from ultra-low-power states.
Technical Context
The R5F100LEDFB#50 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-clock domains: a high-speed on-chip oscillator (±1.0% accuracy, selectable from 1–32 MHz) and a dedicated low-speed oscillator for watchdog and RTC.
Its memory architecture includes 128 KB code flash (1 KB block size, security lockable), 8 KB background-operable data flash (BGO enabled), and 12 KB SRAM. Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, and 3× I²C/Simplified I²C channels - all configurable via register-based control without external 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 |
|---|---|---|---|
| R5F101LEDFB#50 | No data flash (0 KB); identical core, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware logging | Select when data flash is unnecessary and cost reduction is prioritized |
| R5F100LECFB#50 | Same flash/RAM but in LQFP-0.65 mm pitch (PLQP0064JA-A); different land pattern and thermal profile | Requires PCB redesign due to larger pitch and footprint; less suitable for high-density layouts | Choose only if legacy board compatibility with 0.65 mm pitch is required |
Compared with R5F100LEDFB#50, R5F101LEDFB#50 removes data flash to lower unit cost but sacrifices field-updatable configuration storage, while R5F100LECFB#50 retains full functionality but mandates a less compact PCB layout - making R5F100LEDFB#50 optimal for new industrial designs balancing density, nonvolatile data retention, and thermal reliability.

FAQ
What is the operating temperature range of the R5F100LEDFB#50?
The R5F100LEDFB#50 is rated for industrial operation from -40°C to +105°C, as indicated by the 'G' suffix in its part number. This makes it suitable for deployment in harsh environments such as factory automation controllers, outdoor utility meters, and motor drive interfaces where ambient temperatures exceed consumer-grade limits.
Does the R5F100LEDFB#50 support in-system programming via standard interfaces?
Yes, the R5F100LEDFB#50 supports on-chip debug and self-programming via its built-in FINE interface using a standard Renesas E2 emulator or compatible debug probe. It also provides boot swap functionality and flash shield window protection - enabling secure, field-upgradable firmware without external programmers.
How many I²C interfaces does the R5F100LEDFB#50 include, and are they fully independent?
The R5F100LEDFB#50 includes three I²C/Simplified I²C channels (IIC00, IIC01, IIC02), each with dedicated SCL/SDA pins and independent registers. All support standard-mode (100 kbps) and fast-mode (400 kbps) operation, and can be used simultaneously for connecting multiple sensors, EEPROMs, or display controllers without software arbitration.
Can the R5F100LEDFB#50 operate from a single 1.8 V supply?
No - the R5F100LEDFB#50 requires a minimum VDD of 1.6 V but is not specified for reliable operation at 1.8 V alone across all peripherals and frequencies. Its guaranteed operational range is 1.6 V to 5.5 V, with full 32 MHz performance requiring ≥2.7 V per the datasheet's DC characteristics table; 1.8 V operation is limited to reduced frequency and subset of peripherals.
Is there hardware support for LIN bus communication on the R5F100LEDFB#50?
Yes, the R5F100LEDFB#50 supports LIN 2.2 protocol through its UART peripherals - specifically UART0 and UART1 - which include automatic LIN break detection, sync field generation, and checksum calculation. This enables direct connection to LIN transceivers without external protocol accelerators.
