Product details
Overview
R5F101LLDFB#V0 from Renesas is a 64-pin LFQFP, 0.5-mm pitch, industrial-grade (–40°C to +85°C) RL78/G13 16-bit MCU with 128 KB flash, 12 KB RAM, and no data flash memory. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active current, and supports ultra-low-power STOP mode (0.57 μA with RTC + LVD), targeting battery-powered and energy-sensitive embedded control applications.
For engineers reviewing the R5F101LLDFB#V0 datasheet, R5F101LLDFB#V0 pinout, R5F101LLDFB#V0 application, or R5F101LLDFB#V0 equivalent, key selection considerations include its integrated 10-bit ADC (26 channels), real-time clock with calendar/alarm, dual UART/LIN support, and hardware DMA-critical for sensor fusion, motor control, and smart appliance designs requiring deterministic low-power operation.
Technical Context
The R5F101LLDFB#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable), 16-bit timer array (16 channels), and background operation-capable peripherals including UART, CSI, and I²C.
Its power architecture includes HALT, STOP, and SNOOZE modes, POR, and an LVD with 14 interrupt/reset levels. The device supports self-programming of code flash with boot swap and flash shield window functions, but excludes on-chip data flash-relying instead on external storage or code flash emulation for nonvolatile data.

FAQ
Does R5F101LLDFB#V0 include on-chip data flash memory?
No, R5F101LLDFB#V0 does not include data flash memory. It features 128 KB of code flash only. Data storage must be implemented externally or emulated in code flash using Renesas' Flash Self-Programming Library. This distinguishes it from the R5F101LLAFB#V0 variant, which includes 8 KB of dedicated data flash.
What is the maximum operating frequency and associated performance of R5F101LLDFB#V0?
R5F101LLDFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports configurable instruction timing-from 0.03125 μs (high-speed mode) to 30.5 μs (ultra-low-speed mode)-enabling dynamic power/performance scaling.
Which serial communication interfaces are supported by R5F101LLDFB#V0?
R5F101LLDFB#V0 supports up to 4 UART/LIN channels, 8 CSI (SPI-compatible) channels, and 10 I²C/Simplified I²C channels. These interfaces operate concurrently and are mapped to flexible GPIO pins, allowing simultaneous connection to displays, sensors, and communication transceivers without external logic.
What low-power modes are available on R5F101LLDFB#V0, and what is the lowest achievable current draw?
R5F101LLDFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-enabling multi-year battery operation in intermittent-sensing applications such as environmental monitors and utility meters.
Is R5F101LLDFB#V0 pin-compatible with other RL78/G13 64-pin variants?
Yes, R5F101LLDFB#V0 shares identical pinout and package (64-pin LFQFP, 0.5-mm pitch) with all other RL78/G13 devices in the same pin-count group-including R5F100LLDFB#V0 and R5F101LLAFB#V0-allowing drop-in replacement within the same footprint when functional requirements align.
What development tools are officially supported for R5F101LLDFB#V0 firmware development?
R5F101LLDFB#V0 is fully supported by Renesas e² studio IDE, CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Hardware debugging uses the E2 emulator Lite or E2 emulator, both connecting via the 10-pin JTAG/SWD interface defined in the R5F101LLDFB#V0 datasheet.
