Product details
Overview
R5F104BFDFP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 64 KB flash, 5.5 KB RAM, and 44-pin LQFP-0.8 mm package, operating from 1.6–5.5 V at -40 to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, integrates 10-bit ADC (12 channels), UART/SPI/I²C interfaces, RTC, and ultra-low-power HALT/STOP modes (0.60 μA RTC+LVD). Used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104BFDFP#V0 datasheet, R5F104BFDFP#V0 pinout, R5F104BFDFP#V0 application, or R5F104BFDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm footprint, 64 KB code flash with data flash shield window, 10-bit ADC with internal reference, and support for LIN-bus UART - critical for deterministic real-time embedded control in constrained industrial environments.
Technical Context
The R5F104BFDFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It embeds a configurable Data Transfer Controller (DTC) activated by 19–26 event sources via the Event Link Controller (ELC), enabling autonomous peripheral-to-memory transfers without CPU intervention.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, and multiple low-power modes (HALT, STOP, SNOOZE) coordinated with the high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz). The device supports background operation (BGO) during data flash rewriting and self-programming with boot swap functionality.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BFDFP#V0?
The R5F104BFDFP#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 44 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the RL78/G14 datasheet (R01DS0053EJ0340) and reflects the efficiency of the 3-stage pipeline CISC core. The R5F104BFDFP#V0 maintains this rating across its full industrial temperature range (-40°C to +85°C) and supply voltage (1.6–5.5 V).
Does the R5F104BFDFP#V0 support LIN bus communication, and if so, how is it implemented?
Yes, the R5F104BFDFP#V0 supports LIN bus communication through its UART peripheral. The datasheet explicitly states "UART/UART (LIN-bus supported)" for RL78/G14 devices, and the R5F104BFDFP#V0's UART channels (e.g., UART0 on P16/P17 or UART2 on P13/P14) can be configured for LIN physical layer compliance using standard UART frame formatting and break detection. No external transceiver is required for basic LIN slave functionality, though an external LIN transceiver is needed for master or bus arbitration roles.
What are the flash memory organization and write endurance specifications for the R5F104BFDFP#V0?
The R5F104BFDFP#V0 contains 64 KB of code flash memory organized in 1 KB blocks, and 4 KB of data flash memory. The data flash supports background operation (BGO), allowing program execution during erase/write cycles. Its write endurance is rated at 1,000,000 cycles (typical) across the full VDD range (1.8–5.5 V), with no minimum voltage requirement for read operations. These values are specified in Section 1.1 of the RL78/G14 datasheet and apply directly to the R5F104BFDFP#V0 variant.
How many analog input channels does the R5F104BFDFP#V0's ADC support, and what reference options are available?
The R5F104BFDFP#V0 integrates a 10-bit successive-approximation ADC with 12 analog input channels (ANI0–ANI11), as confirmed by the pin configuration table for 44-pin LQFP packages. Reference options include the internal 1.45 V bandgap reference (AVREFP/AVREFM pins), external reference applied to AVREFP/AVREFM, or VDD as reference. The internal reference enables standalone operation without external components, critical for compact industrial sensor designs.
Is the R5F104BFDFP#V0 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
Yes, the R5F104BFDFP#V0 is fully pin-compatible with all other RL78/G14 devices in the 44-pin LQFP-0.8 mm package (PLQP0044GC-A), including R5F104BEAFP#V0, R5F104BGDFP#V0, and R5F104FFDFP#V0. Pin functions, power/ground locations, reset, REGC, and oscillator pins are identical across this package group. Peripheral I/O redirection (via PIOR0/PIOR1 registers) ensures consistent signal routing regardless of flash/RAM configuration, enabling hardware reuse across firmware variants.
