Product details
Overview
R5F100LDDFB#V0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation (−40°C to +85°C). It integrates a real-time clock, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered sensor nodes and motor control subsystems.
For engineers reviewing the R5F100LDDFB#V0 datasheet, R5F100LDDFB#V0 pinout, R5F100LDDFB#V0 application, or R5F100LDDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated data flash with background operation, 10-bit ADC accuracy across 1.6–5.5 V supply, and support for SNOOZE mode wake-up via serial interface events.
Technical Context
The R5F100LDDFB#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz low-speed mode). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite cycles, and 12 KB on-chip RAM - all accessible under single 1.6–5.5 V supply.
Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 2–4 channel DMA, and multi-protocol serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C - all configurable for low-latency interrupt-driven operation in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LDGFB#V0 | Same 128 KB flash, 8 KB data flash, 12 KB RAM, but rated for −40°C to +105°C (G-grade industrial) | Required for extended-temperature environments such as enclosed outdoor enclosures or engine bay proximity | Select when ambient operating temperature exceeds +85°C; otherwise identical peripheral and software compatibility |
| R5F101LDDFB#V0 | Identical package and pinout, but lacks data flash memory (0 KB); retains 128 KB code flash and 12 KB RAM | Suitable where firmware-only storage is sufficient and data logging or field-upgradable parameters are not required | Choose to reduce BOM cost and simplify flash management when persistent parameter storage is handled externally |
Compared with R5F100LDDFB#V0, R5F100LDGFB#V0 adds extended temperature capability without changing footprint or firmware, while R5F101LDDFB#V0 removes data flash to lower cost - making the former ideal for harsh environments and the latter for fixed-function deployments.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LDDFB#V0?
The R5F100LDDFB#V0 operates up to 32 MHz with a typical current draw of 66 μA per MHz in HALT mode. At full 32 MHz execution, total active current is approximately 2.1 mA (VDD = 3.3 V, TA = 25°C), while STOP mode with only RTC and LVD active consumes just 0.57 μA - enabling multi-year battery life in duty-cycled sensor applications.
Does the R5F100LDDFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100LDDFB#V0 supports full in-system programming via on-chip debug interface (E1/E20) and includes flash security features: block erase/write prohibition, boot swap functionality, and flash shield window for protected code regions. These capabilities allow safe field firmware updates and intellectual property protection without requiring external programmers.
How many serial communication interfaces does the R5F100LDDFB#V0 provide, and what protocols are supported?
The R5F100LDDFB#V0 provides up to 8 CSI (SPI-compatible) channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - with significant pin multiplexing. All three interface types share common port pins, allowing flexible allocation based on system requirements without increasing pin count or PCB complexity.
What ADC performance specifications apply to the R5F100LDDFB#V0, and are calibration registers included?
The R5F100LDDFB#V0 features a 10-bit successive approximation ADC with 26 input channels, 1.45 V internal reference voltage, and integrated temperature sensor. It achieves ±2 LSB integral nonlinearity (INL) and includes factory-trimmed calibration data stored in ROM - enabling high-accuracy measurements across the full 1.6–5.5 V supply range without external reference components.
Is the R5F100LDDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LFQFP package (e.g., R5F100LCAFB#V0, R5F100LLAFB#V0) share identical pinouts and electrical characteristics. This allows hardware design reuse across memory variants - for example, upgrading from 64 KB to 128 KB flash by replacing R5F100LCDFB#V0 with R5F100LDDFB#V0 without PCB changes.
