Product details
Overview
R5F100FDAFP#V0 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and integrated RTC, ADC, UART, I²C, and SPI interfaces - deployed in industrial sensor nodes, smart metering front-ends, and low-power HMI controllers.
For engineers reviewing the R5F100FDAFP#V0 datasheet, R5F100FDAFP#V0 pinout, R5F100FDAFP#V0 application, or R5F100FDAFP#V0 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D), 1.6–5.5 V wide supply range, 66 μA/MHz active current, and on-chip debug support for rapid firmware validation in battery-powered edge devices.
Technical Context
The R5F100FDAFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz sub-system clock). It integrates a 12-bit interval timer, calendar-mode real-time clock with alarm and correction, and a 10-bit 26-channel ADC with internal 1.45 V reference and temperature sensor.
Power management includes HALT, STOP, and SNOOZE modes; the device achieves 0.57 μA in STOP mode with RTC + LVD active. Its serial interface suite comprises up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable via dedicated peripheral control registers without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FDASP#V0 | Same core, memory, and peripherals; 30-pin LSSOP package (7.62 mm, 0.65 mm pitch) | Fits space-constrained PCBs where 44-pin LQFP layout is impractical | Select when board area is critical and I/O count ≤ 24 is sufficient |
| R5F101FDAFP#V0 | Identical package and pinout; lacks data flash (0 KB) and self-programming capability | Used in cost-sensitive applications where field firmware updates are unnecessary | Choose when boot ROM-only operation suffices and BGO/data retention is not required |
Compared with R5F100FDAFP#V0, R5F100FDASP#V0 trades I/O count and thermal performance for compactness, while R5F101FDAFP#V0 removes data flash to reduce cost and simplify qualification - both require no schematic changes but differ in firmware update capability and layout constraints.

FAQ
What is the operating temperature grade of the R5F100FDAFP#V0?
The R5F100FDAFP#V0 is rated for industrial operation from -40°C to +85°C (denoted by "D" in the part number suffix). It does not support the extended +105°C grade ("G") or consumer-grade +85°C with different qualification testing. This makes R5F100FDAFP#V0 suitable for factory automation, building controls, and outdoor metering where ambient stability is critical.
Does the R5F100FDAFP#V0 include an integrated temperature sensor?
Yes, the R5F100FDAFP#V0 includes an on-chip temperature sensor usable with the 10-bit ADC. It is accessible only in HS (high-speed main) mode and provides calibrated output referenced to the internal 1.45 V bandgap. The sensor enables thermal monitoring in motor drives, power supplies, and sealed enclosures without adding external components - directly supported by Renesas' standard RL78 driver libraries.
Can the R5F100FDAFP#V0 perform flash self-programming during runtime?
Yes, the R5F100FDAFP#V0 supports full self-programming of both code and data flash memory during application execution. It implements boot swap functionality for safe firmware updates and flash shield window protection to prevent unauthorized access. Background operation (BGO) allows code execution from flash while rewriting data flash - essential for logging, configuration storage, and OTA update resilience in R5F100FDAFP#V0-based systems.
How many UART channels does the R5F100FDAFP#V0 support, and do they support LIN bus?
The R5F100FDAFP#V0 supports up to four UART channels, all of which are LIN-bus compliant per ISO 17987-4. Each UART includes break-detection, sync-field generation, and checksum calculation hardware - enabling direct integration into automotive body electronics, HVAC controllers, and industrial networks using single-wire physical layers. This LIN capability is natively implemented in the UART peripheral and requires no software bit-banging.
What debug interface does the R5F100FDAFP#V0 use, and is it compatible with standard tools?
The R5F100FDAFP#V0 uses Renesas' on-chip debug interface accessible via the TOOLRxD/TOOLTxD pins (shared with UART0), supporting full JTAG-style debugging including breakpoints, watchpoints, and memory inspection. It is compatible with Renesas E2 emulator, E2 Lite, and third-party tools like Segger J-Link (with appropriate firmware and configuration). No external debug chip is needed - the interface is fully integrated and activated automatically when debug mode is entered.
