Product details
Overview
R5F100LLDFB#V0 from Renesas is a 64-pin LFQFP, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit MCU operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LLDFB#V0 datasheet, R5F100LLDFB#V0 pinout, R5F100LLDFB#V0 application, or R5F100LLDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, integrated RTC + LVD + BGO data flash, 10-bit 26-channel ADC, and support for LIN/UART/I²C/CSI interfaces in extended temperature (–40°C to +105°C) industrial environments.
Technical Context
The R5F100LLDFB#V0 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 subsystem clock), and features on-chip debug, self-programming with boot swap, and background operation during data flash rewrite.
It integrates dual power management systems - a POR circuit and configurable 14-level LVD - alongside a DMA controller (4 channels), 16×16/32÷32 multiplier/divider, and peripheral-rich timing subsystem including eight 16-bit timers, one 12-bit interval timer, one calendar RTC, and one watchdog timer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LLDFB#V0 | No data flash (0 KB); identical core, peripherals, and package; lower cost where non-volatile parameter storage is handled externally | Unsuitable for field-upgradable firmware or persistent logging; requires external EEPROM/NVRAM for configuration storage | Select when data flash is unnecessary and BOM cost reduction is prioritized over integrated non-volatile storage |
| R5F100LLAFB#V0 | Same 512 KB flash, 8 KB data flash, 32 KB RAM, but LQFP-64 (0.65 mm pitch) instead of LFQFP-64 (0.5 mm pitch); different land pattern and thermal profile | Requires PCB redesign due to larger pitch and footprint; preferred where legacy LQFP tooling or thermal dissipation requirements favor 0.65 mm pitch | Choose for compatibility with existing LQFP-64 assembly lines or when enhanced thermal performance justifies layout change |
Compared with R5F100LLDFB#V0, R5F101LLDFB#V0 removes data flash to reduce cost and die size while retaining identical processing capability, whereas R5F100LLAFB#V0 maintains full feature parity but shifts to a more widely supported 0.65 mm pitch LQFP package - offering trade-offs between integration density, manufacturing compatibility, and non-volatile storage needs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LLDFB#V0?
The R5F100LLDFB#V0 operates up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS at that frequency. Its RL78 CPU core achieves this performance with a 3-stage pipeline and supports scalable instruction timing - from 0.03125 μs per instruction at 32 MHz down to 30.5 μs at 32.768 kHz - enabling both high-throughput and ultra-low-power operation within the same R5F100LLDFB#V0 device.
Does the R5F100LLDFB#V0 include an integrated real-time clock (RTC), and what calendar functionality does it support?
Yes, the R5F100LLDFB#V0 includes a hardware RTC with calendar mode supporting year/month/day/hour/minute/second values across a 99-year range (2000–2099), plus alarm interrupt, periodic interrupt, and clock correction functions. It operates independently in STOP mode with only 0.57 μA current draw when powered by VDD, making it suitable for time-stamped logging and scheduled wake-up in battery-powered R5F100LLDFB#V0 deployments.
How many analog-to-digital converter (ADC) channels does the R5F100LLDFB#V0 support, and what reference options are available?
The R5F100LLDFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference voltages or internal references - including a factory-trimmed 1.45 V reference and a calibrated temperature sensor - all selectable via register configuration. This flexibility allows precise sensor interfacing across varying supply conditions without external reference ICs in the R5F100LLDFB#V0 design.
What low-power modes are available on the R5F100LLDFB#V0, and what is the typical current consumption in each?
The R5F100LLDFB#V0 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, only the RTC and LVD remain operational, enabling ultra-low standby current for long-life battery applications. SNOOZE allows selected peripherals (e.g., UART, ADC) to run while CPU sleeps, reducing average power without sacrificing responsiveness - all verified under actual R5F100LLDFB#V0 operating conditions per Renesas datasheet R01DS0131EJ0380.
Is the R5F100LLDFB#V0 pin-compatible with other RL78/G13 variants in the same package, such as R5F101LLDFB#V0?
Yes, the R5F100LLDFB#V0 is pin-compatible with R5F101LLDFB#V0 - both are 64-pin LFQFP-0.5 mm devices sharing identical pinout, electrical characteristics, and peripheral mapping. The only functional difference is the absence of data flash in R5F101LLDFB#V0; all GPIO, ADC, timer, and communication pins align exactly, allowing drop-in replacement where data flash is not required in the R5F100LLDFB#V0 application.
