It integrates 12-bit RTC, 10-bit ADC (16 channels), UART/LIN, I²C, SPI, 16-bit timers, and ultra-low-power modes (0.60 μA in RTC+LVD mode). Used in battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104JJAFA#30 datasheet, R5F104JJAFA#30 pinout, R5F104JJAFA#30 application, or R5F104JJAFA#30 equivalent, key selection criteria include its 52-pin LQFP package, -40°C to +105°C industrial temperature rating, 256 KB code flash with self-programming support, and integrated LIN-capable UART for automotive body electronics interoperability.
Technical Context
The R5F104JJAFA#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 256 KB on-chip flash (1 KB block size), 8 KB data flash with background operation (BGO), and 20 KB RAM.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, 10-bit ADC with internal reference and temperature sensor, and serial interfaces: 3–4 UART/LIN channels, 4–10 I²C channels, and 3–8 CSI (SPI-compatible) channels - all configurable via Event Link Controller (ELC) for hardware-triggered event chaining.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104JJAFA#30?
The R5F104JJAFA#30 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 architecture and validated under standard test conditions per Renesas documentation. The R5F104JJAFA#30 achieves this throughput while maintaining ultra-low power consumption - 66 μA per MHz in HALT mode - making it suitable for compute-constrained, battery-operated applications where both speed and efficiency matter.
Does the R5F104JJAFA#30 support LIN bus communication, and if so, which UART channel implements it?
Yes, the R5F104JJAFA#30 supports LIN 2.2-compliant communication via its UART2 peripheral (mapped to P13/P14 pins), which includes automatic synchronization, checksum calculation, and break detection. This capability is confirmed in the RL78/G14 datasheet section "Serial Interfaces" and applies specifically to the R5F104JJAFA#30 variant. The R5F104JJAFA#30 uses UART2's LIN mode for reliable sub-network messaging in automotive body electronics and industrial control nodes.
What are the flash memory configuration details - block size, security features, and self-programming capability - for the R5F104JJAFA#30?
The R5F104JJAFA#30 contains 256 KB of on-chip code flash organized in 1 KB erasable blocks, with prohibition of block erase/write enabled via flash security lock. It supports self-programming with boot swapping and flash shield window protection, allowing safe firmware updates without external programming hardware. These features are documented in the RL78/G14 datasheet Section 1.1 "Features" and apply identically to the R5F104JJAFA#30 as part of the RL78/G14 family specification.
How many analog input channels and what ADC resolution does the R5F104JJAFA#30 provide?
The R5F104JJAFA#30 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI15, plus ANI16–ANI19 on selected pins), supporting internal 1.45 V reference and temperature sensor measurement. This ADC configuration is explicitly listed in the RL78/G14 datasheet Table "A/D Converter" and confirmed for the R5F104JJAFA#30 through its membership in the 52-pin, G-grade, 256 KB flash variant group.
What is the industrial temperature grade and package type of the R5F104JJAFA#30, and how is it indicated in the part number?
The R5F104JJAFA#30 is an industrial-grade device rated for -40°C to +105°C operation (G-grade), housed in a 52-pin LQFP package with 0.65 mm pitch. This is encoded in the part number: "J" denotes 256 KB flash, "J" in position 7–8 indicates 52-pin count, "AFA" specifies LQFP-0.65 mm, and "#30" denotes tray packaging. The "G" temperature grade is implied by the suffix "G" in the broader RL78/G14 family designation and confirmed in Renesas ordering tables for R5F104JxGFA variants.
