It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial sensors and motor control interfaces requiring integrated analog peripherals and LIN-capable UART.
For engineers reviewing the R5F104JCDFA#V0 datasheet, R5F104JCDFA#V0 pinout, R5F104JCDFA#V0 application, or R5F104JCDFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, 96 KB/12 KB/8 KB memory configuration, -40 to +85°C industrial temperature rating, and support for background data flash rewriting, real-time clock calendar, and dual-channel 8-bit DAC.
Technical Context
The R5F104JCDFA#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). Its power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selection.
Peripheral integration includes 10-channel 10-bit ADC (20 inputs), two 8-bit DACs, up to 12× 16-bit timers (including TAU, Timer RJ/RD/RG), real-time clock with calendar/alarm, watchdog timer, and serial interfaces: 3–4 UART/LIN channels, 4–10 I²C, and 3–8 CSI (SPI-compatible) channels - all configurable via Event Link Controller (ELC) and Data Transfer Controller (DTC).

FAQ
What is the maximum operating frequency and associated DMIPS rating of the R5F104JCDFA#V0?
The R5F104JCDFA#V0 achieves a maximum operating frequency of 32 MHz with a measured performance of 44 DMIPS. This rating reflects integer instruction throughput under typical compiler-optimized code and accounts for the RL78 core's 3-stage pipeline efficiency, including multiply/divide instruction support. The on-chip high-speed oscillator maintains ±1.0% accuracy across the full industrial temperature range (-40 to +85°C), ensuring deterministic timing for real-time control loops in the R5F104JCDFA#V0.
Does the R5F104JCDFA#V0 support background data flash rewriting (BGO), and what is the minimum VDD required?
Yes, the R5F104JCDFA#V0 supports Background Operation (BGO) for data flash rewriting, allowing program execution from code flash while simultaneously erasing or programming the 8 KB data flash area. The minimum VDD required for BGO is 1.8 V, consistent with its full operational range of 1.6–5.5 V. This capability enables safe, non-interrupting firmware parameter updates in field-deployed devices without halting real-time functions-a critical feature implemented directly in the R5F104JCDFA#V0's flash control peripheral.
How many analog input channels and what ADC resolution does the R5F104JCDFA#V0 provide?
The R5F104JCDFA#V0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM reference pins and an on-chip temperature sensor. It supports selectable conversion clock sources and automatic scanning across multiple channels. This ADC implementation-fully specified in the R5F104JCDFA#V0 datasheet-delivers 1 LSB integral nonlinearity and supports both single-ended and differential measurement modes for precision sensor interfacing.
What serial communication interfaces are available on the R5F104JCDFA#V0, and which support LIN bus physical layer compliance?
The R5F104JCDFA#V0 provides three UART channels (UART0, UART1, UART2), four I²C channels (I²C0–I²C3), and up to eight CSI (SPI-compatible) channels. UART0 and UART2 explicitly support LIN bus protocol-including break detection, sync field handling, and checksum generation-as confirmed in the RL78/G14 peripheral specification. This LIN capability is natively embedded in the UART hardware block of the R5F104JCDFA#V0 and requires no external transceiver for basic slave-node functionality.
What is the industrial temperature grade and package type of the R5F104JCDFA#V0, and how is it indicated in the part number?
The R5F104JCDFA#V0 is rated for industrial operation from -40 to +85°C, denoted by the "D" suffix in its ordering code (R5F104JCDFA#V0). Its package is a 52-pin plastic LQFP with 10 × 10 mm body and 0.65 mm lead pitch, indicated by "FA" (LQFP-0.65 mm) and "#V0" (tray packaging specification). This configuration is validated for use in harsh environments such as factory automation and building management systems where thermal stability and mechanical reliability are essential for the R5F104JCDFA#V0.
