Product details
Overview
R5F100BFDNA#U0 from Renesas is a 32-pin, HWQFN-packaged RL78/G13 16-bit microcontroller with 96 KB flash memory, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz (41 DMIPS), optimized for ultra-low-power industrial control applications including sensor nodes and battery-powered HMI modules.
For engineers reviewing the R5F100BFDNA#U0 datasheet, R5F100BFDNA#U0 pinout, R5F100BFDNA#U0 application, or R5F100BFDNA#U0 equivalent, key selection criteria include its 0.57 μA STOP-mode current, integrated RTC + LVD, 10-bit 26-channel ADC, and hardware UART/LIN support for robust serial communication in space-constrained embedded designs.
Technical Context
The R5F100BFDNA#U0 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). It integrates a 2-channel DMA controller, 16-bit × 16-bit multiply-accumulate unit, and background operation (BGO) for concurrent code execution during data flash rewriting.

Does the R5F100BFDNA#U0 support hardware LIN communication?
Yes, the R5F100BFDNA#U0 supports LIN 2.2-compliant communication via UART0 channel with dedicated hardware features: automatic sync-break detection, checksum generation (classic and enhanced), and configurable baud rates down to 1.2 kbps. These capabilities are confirmed in Section 1.1 Features and Section 17.3.2 of the R01DS0131EJ0380 datasheet, enabling reliable body electronics integration without external transceivers.
How much data flash endurance does the R5F100BFDNA#U0 provide?
The R5F100BFDNA#U0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V, as specified in Section 1.1 Features of R01DS0131EJ0380. Its background operation (BGO) mode allows concurrent program execution during rewrites, making it ideal for logging runtime parameters, calibration data, or event counters in long-lifecycle industrial devices.
What debug and programming interfaces are supported by the R5F100BFDNA#U0?
The R5F100BFDNA#U0 supports on-chip debugging via the single-wire debug interface (SWD) using the TOOLx pins (e.g., TOOLRxD on P11), compatible with Renesas E2 emulator and CS+ IDE. It also supports self-programming via on-chip bootloader, enabling field firmware updates over UART or SPI without external programmers - all documented in Sections 22.2 and 23.1 of R01DS0131EJ0380.
Is the R5F100BFDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100BFDNA#U0 shares identical 32-pin HWQFN pinout and electrical characteristics with all other R5F100xxDNA#U0 and R5F101xxDNA#U0 variants (e.g., R5F100BGDNA#U0, R5F101BFDNA#U0), as verified in Table 1-1 and Figure 1-1 of R01DS0131EJ0380. This enables drop-in replacement within the same memory/configuration tier, provided firmware accommodates memory map differences.
