Product details
Overview
R5F104BEDFP#V0 from Renesas is a 32-bit RL78/G14 microcontroller featuring 48 KB flash memory, 5.5 KB RAM, and 44-pin LQFP-0.8 mm package. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, supports -40°C to +85°C industrial temperature range (D-grade), and integrates 10-bit ADC (8 channels), UART/SPI/I²C interfaces, RTC, and ultra-low-power HALT/STOP modes for embedded control in battery-powered systems.
For engineers reviewing the R5F104BEDFP#V0 datasheet, R5F104BEDFP#V0 pinout, R5F104BEDFP#V0 application, or R5F104BEDFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm footprint, D-grade industrial qualification, 48 KB flash/5.5 KB RAM configuration, integrated 10-bit ADC with internal reference, and support for LIN-bus-capable UART channels in resource-constrained industrial sensing and actuation designs.
Technical Context
The R5F104BEDFP#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 high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz), hardware Data Transfer Controller (DTC), and Event Link Controller (ELC) for peripheral event chaining without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes achieving 66 μA/MHz active current and 0.60 μA RTC+LVD retention current. Peripheral integration covers Timer Array Unit (TAU), 12-bit interval timer, watchdog timer, and real-time clock with calendar/alarm functions - all optimized for deterministic low-power operation in sensor nodes and motor control edge devices.

Yes, the R5F104BEDFP#V0 supports LIN bus communication through its UART channels - specifically UART0, UART1, and UART2 - with built-in LIN break detection and sync field generation. This eliminates the need for external LIN transceivers in basic node implementations and reduces system-level BOM count.
What are the flash and RAM capacities of the R5F104BEDFP#V0, and how are they allocated?
The R5F104BEDFP#V0 integrates 48 KB of code flash memory and 5.5 KB of on-chip RAM. Flash is organized in 1 KB blocks with erase/write protection features; RAM includes dedicated areas for stack, heap, and peripheral register shadowing - verified in Renesas' Flash Self-Programming Library documentation (R20UT2944).
Which package type and pin count does the R5F104BEDFP#V0 use, and what is its pitch?
The R5F104BEDFP#V0 uses a 44-pin LQFP package (RENESAS code PLQP0044GC-A) with 10 × 10 mm body size and 0.8 mm pin pitch. This footprint is compatible with standard PCB manufacturing processes and supports hand-soldering for prototyping while maintaining thermal performance in industrial enclosures.
What industrial temperature grade is specified for the R5F104BEDFP#V0, and how is it indicated in the part number?
The R5F104BEDFP#V0 is rated for -40°C to +85°C operation and carries the 'D' grade designation - encoded in the fourth character of the base part number 'R5F104BEDFP', where 'E' corresponds to 48 KB flash and 'D' confirms industrial temperature qualification per Renesas ordering conventions.
