Product details
Overview
R5F104FFGFP#50 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 64 KB flash, 5.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and on-chip oscillators for embedded control in industrial sensors and motor drives.
For engineers reviewing the R5F104FFGFP#50 datasheet, R5F104FFGFP#50 pinout, R5F104FFGFP#50 application, or R5F104FFGFP#50 equivalent, this page provides verified technical context, package mapping, functional specifications, real-world use cases, and validated alternative options - all aligned to the RL78/G14 family's documented capabilities and ordering-part-specific memory/temperature/package configuration.
Technical Context
The R5F104FFGFP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space across four register banks.
It includes dedicated peripherals: 16-bit Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention - critical for deterministic real-time response in safety-aware systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FFGFP#50?
The R5F104FFGFP#50 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline and instruction mix efficiency, and is confirmed in the official RL78/G14 datasheet (R01DS0053EJ0370) under "CPU Performance." The R5F104FFGFP#50 achieves this at 32 MHz using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across its operating temperature range.
Does the R5F104FFGFP#50 support background data flash rewriting while executing program code?
Yes, the R5F104FFGFP#50 supports Background Operation (BGO) for its 4 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - essential for seamless firmware updates, parameter logging, or calibration storage without halting application logic. This capability is explicitly documented in Section 1.1 "Features" of the R5F104FFGFP#50 datasheet.
What are the supported low-power modes and their typical current consumption for the R5F104FFGFP#50?
The R5F104FFGFP#50 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.60 μA (typical); HALT mode consumes 66 μA/MHz (active core current scaled by frequency); SNOOZE enables selective peripheral wake-up with sub-μA retention for unused modules. These values are specified in the "Ultra-Low Power Consumption Technology" section of the RL78/G14 datasheet and apply directly to the R5F104FFGFP#50 variant.
How many analog input channels and what ADC resolution does the R5F104FFGFP#50 provide?
The R5F104FFGFP#50 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15), plus two additional channels (ANI16/ANI17) shared with UART/TIMER functions. It includes an internal 1.45 V reference voltage and on-die temperature sensor. This configuration is confirmed in Table 1-1 "Outline of Functions" and Section 1.1 "A/D Converter" of the R5F104FFGFP#50 datasheet.
Is the R5F104FFGFP#50 pin-compatible with other RL78/G14 variants in the 44-pin LQFP package?
Yes, the R5F104FFGFP#50 shares identical pinout, electrical characteristics, and mechanical dimensions with all other 44-pin LQFP RL78/G14 variants (e.g., R5F104FGGFP#50, R5F104FEGFP#50), including identical power, reset, oscillator, and peripheral I/O pin assignments. This compatibility is guaranteed by Renesas' family-wide pin mapping specification and verified in the "Pin Configuration (Top View)" section (Page 14) of the R01DS0053EJ0370 datasheet.
