Product details
Overview
R5F104PKAFA#30 from Renesas is a 100-pin LQFP-0.65 mm pitch, 256 KB flash, 24 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), integrated 10-bit ADC (16 channels), RTC, and dual UART/LIN interfaces - deployed in industrial motor control and smart sensor nodes requiring extended battery life and deterministic real-time response.
For engineers reviewing the R5F104PKAFA#30 datasheet, R5F104PKAFA#30 pinout, R5F104PKAFA#30 application, or R5F104PKAFA#30 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D-grade), 1.6–5.5 V supply range, on-chip debug support, and compatibility with Renesas' CS+ and e² studio toolchains for rapid firmware development and low-power mode validation.
Technical Context
The R5F104PKAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a Data Transfer Controller (DTC) for autonomous peripheral-to-memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, with 0.60 μA RTC+LVD retention current. The device features a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable), 12-bit interval timer, watchdog timer, and background operation (BGO) for data flash rewriting while executing code from program memory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104PLAFA#30 | Same 100-pin LQFP package, identical peripherals, but 384 KB flash and 32 KB RAM | Preferred for designs requiring larger firmware image size or extended data logging buffer | Select when future firmware growth or OTA update partitioning necessitates >256 KB code space |
| R5F104PKAFB#30 | Same 256 KB flash/24 KB RAM spec, but 100-pin LFQFP (0.5 mm pitch) package instead of LQFP (0.65 mm) | Used where PCB layout density demands finer-pitch components and automated optical inspection is available | Choose only if assembly process supports 0.5 mm pitch; no electrical or functional difference from R5F104PKAFA#30 |
Compared with R5F104PKAFA#30, R5F104PLAFA#30 offers headroom for complex control algorithms and secure boot partitions, while R5F104PKAFB#30 trades PCB assembly simplicity for higher component density - neither alters peripheral capability or power behavior.

FAQ
What is the operating temperature range for the R5F104PKAFA#30?
The R5F104PKAFA#30 is rated for industrial operation from -40°C to +85°C (D-grade). This specification is confirmed in the ordering information section of the R01DS0053EJ0370 datasheet, where the "D" suffix denotes the industrial temperature grade. It does not support the extended -40°C to +105°C (G-grade) range.
Does the R5F104PKAFA#30 include an integrated temperature sensor?
Yes, the R5F104PKAFA#30 includes an on-chip temperature sensor usable with the 10-bit ADC. As specified in the "A/D Converter" feature list, it shares the analog input channel ANI16–ANI19 and uses the internal reference voltage (1.45 V) for measurement - enabling board-level thermal monitoring without external components.
How many UART/LIN channels does the R5F104PKAFA#30 support?
The R5F104PKAFA#30 supports four UART/LIN channels. This is explicitly stated in the "Serial Interfaces" section of the datasheet under RL78/G14 features. Each channel can operate in UART mode or LIN bus mode with automatic sync-break detection and checksum generation.
Is the R5F104PKAFA#30 pin-compatible with other RL78/G14 variants in the same package?
No - pin compatibility is not guaranteed across RL78/G14 variants even within the same 100-pin LQFP package. The R5F104PKAFA#30 has a fixed pinout defined in Section 1.3.8 of R01DS0053EJ0370. While peripherals are shared across the family, pin assignments for alternate functions (e.g., CSI vs. I²C) differ by memory size and variant, requiring individual schematic validation.
What debug interface does the R5F104PKAFA#30 use?
The R5F104PKAFA#30 uses Renesas' on-chip debug interface accessible via the SWD (Serial Wire Debug) protocol using the RESET and P120 pins. It does not require external JTAG hardware; full debug capabilities including breakpoints, memory inspection, and flash programming are supported through CS+ or e² studio IDEs.
