Product details
Overview
R5F104PKAFB#30 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 256 KB flash, 8 KB data flash, 24 KB RAM, 1.6–5.5 V operation, and ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode). It integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), RTC, and on-chip oscillators up to 32 MHz - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104PKAFB#30 datasheet, R5F104PKAFB#30 pinout, R5F104PKAFB#30 application, or R5F104PKAFB#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, 256 KB code flash with self-programming support, and integrated event link controller (ELC) for deterministic peripheral triggering.
Technical Context
The R5F104PKAFB#30 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 features an address space of 1 MB with four register banks.
Its peripheral subsystem includes a Data Transfer Controller (DTC) with chain transfer, Event Link Controller (ELC) supporting 26 event sources, and dual-voltage interface capability enabling direct connection to 1.8 V, 2.5 V, or 3.0 V devices without level shifters.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104PKAFB#30?
The R5F104PKAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency, active current consumption is 66 μA/MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripheral enablement. In STOP mode with only RTC and LVD active, it draws just 0.60 μA, verified per R01DS0053EJ0370 Rev. 3.70.
Does the R5F104PKAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104PKAFB#30 supports full in-system programming via on-chip debug (SWD interface) and includes flash shield window protection, block erase prohibition, and boot swapping. Its data flash supports background operation (BGO), allowing firmware updates or parameter logging without halting application execution - all confirmed in Section 1.1 Features of R01DS0053EJ0370.
What are the supported serial communication interfaces on the R5F104PKAFB#30?
The R5F104PKAFB#30 integrates four UART channels (with LIN-bus support), up to ten I²C/simplified I²C channels, and three to eight CSI (Renesas' SPI-compatible interface) channels. All are independently configurable and can be remapped via peripheral I/O redirection registers (PIOR0/1), as documented in the RL78/G14 datasheet R01DS0053EJ0370.
How many analog input channels and what ADC resolution does the R5F104PKAFB#30 provide?
The R5F104PKAFB#30 features a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins), operating across the full 1.6–5.5 V supply range. It includes internal 1.45 V reference and temperature sensor - specifications validated in Table 1-1 and Section 1.1 "A/D Converter" of R01DS0053EJ0370.
Is the R5F104PKAFB#30 pin-compatible with other RL78/G14 variants in the same 100-pin LFQFP package?
Yes, all RL78/G14 devices in the 100-pin LFQFP package (e.g., R5F104PJAFB#30, R5F104PLAFB#30, R5F104PKAFB#30) share identical pinouts, electrical characteristics, and peripheral mapping. This allows hardware reuse across memory variants - confirmed by consistent pin configuration diagrams for 100-pin products in Sections 1.3.7–1.3.8 of R01DS0053EJ0370.
