Product details
Overview
R5F100FDAFP#X0 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6–5.5 V. It integrates RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100FDAFP#X0 datasheet, R5F100FDAFP#X0 pinout, R5F100FDAFP#X0 application, or R5F100FDAFP#X0 equivalent, key selection criteria include its 44-pin LQFP package, industrial-grade –40°C to +85°C operation (D-grade), integrated data flash with 1M rewrite cycles, background operation during program execution, and support for LIN-bus via UART.
Technical Context
The R5F100FDAFP#X0 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 subsystem clock). It features on-chip debug, self-programming with boot swap and flash shield window functions, and BGO-capable data flash for concurrent code execution and nonvolatile storage updates.
Power management includes on-chip POR and selectable 14-level LVD with interrupt/reset capability. Peripheral integration covers up to 4 UART/LIN channels, 8 CSI (SPI-compatible) channels, 10 I²C channels, 16× 16-bit timers, real-time clock with calendar/alarm/correction, and 10-bit ADC with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FEAFP#X0 | Same package and core, but 128 KB flash, 8 KB data flash, 12 KB RAM | Higher memory capacity suits more complex control algorithms or larger protocol stacks (e.g., full Modbus TCP offload) | Select when firmware footprint exceeds 96 KB or additional RAM is needed for buffering or RTOS tasks |
| R5F101FDAFP#X0 | Identical pinout and package, but no data flash (only code flash); same 96 KB code flash, 4 KB RAM | Lacks background data rewriting and high-endurance nonvolatile storage - unsuitable for frequent parameter logging | Choose only if data retention requirements are met by external EEPROM or if cost sensitivity outweighs embedded data flash benefits |
Compared with R5F100FDAFP#X0, R5F100FEAFP#X0 offers scalable memory for evolving firmware while maintaining identical power/peripheral behavior, whereas R5F101FDAFP#X0 reduces BOM cost by removing data flash but sacrifices field-updatable configuration storage and wear-leveling capability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FDAFP#X0?
The R5F100FDAFP#X0 operates up to 32 MHz, delivering 41 DMIPS. Its RL78 CPU core supports dynamic clock switching between 1 MHz and 32 MHz using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C. This enables adaptive performance scaling - high speed for computation bursts, low speed for background tasks - without external crystal.
Does the R5F100FDAFP#X0 support LIN bus communication, and how is it implemented?
Yes, the R5F100FDAFP#X0 supports LIN bus communication via its UART peripheral. The UART includes dedicated LIN-mode features: automatic sync-break detection, checksum generation (classic and enhanced), and configurable baud rate timing. No external LIN transceiver is required for basic node functionality, though a compliant transceiver (e.g., TLE7259) must be used for physical layer compliance in automotive applications.
How does the data flash memory in the R5F100FDAFP#X0 differ from standard code flash, and what is its endurance?
The R5F100FDAFP#X0 includes 8 KB of dedicated data flash memory separate from its 96 KB code flash. It supports background operation (BGO), allowing program execution during erase/write cycles. Rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V, it is optimized for frequent parameter storage - unlike code flash, which is intended for firmware and has lower endurance. The flash library reserves specific RAM regions (e.g., FAF00H for R5F100xJ variants) for self-programming operations.
What low-power modes are available on the R5F100FDAFP#X0, and what is the lowest achievable current draw?
The R5F100FDAFP#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. HALT mode consumes 66 μA/MHz, and SNOOZE enables selective peripheral wake-up while CPU remains halted. All modes retain RAM content and support fast wake-up (< 4 μs from HALT), making them ideal for duty-cycled sensor applications.
Is the R5F100FDAFP#X0 pin-compatible with other RL78/G13 devices in the same package, and what design considerations apply?
Yes, the R5F100FDAFP#X0 is pin-compatible with all 44-pin LQFP RL78/G13 variants (e.g., R5F100FAAFP#X0, R5F100FFAFP#X0), sharing identical pin mapping and electrical characteristics. However, memory sizes, peripheral enablement, and data flash presence vary - for example, R5F101FDAFP#X0 omits data flash. PCB layout can be reused, but firmware must validate memory map and feature registers (e.g., PFS register settings, peripheral clocks) for each variant.
