Renesas R5F104PKAFB#10

Overview

R5F104PKAFB#10 from Renesas is a 100-pin LFQFP (0.5 mm pitch), industrial-grade RL78/G14 16-bit microcontroller with 256 KB flash, 24 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. 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 12-bit ADC (16 channels), UART/LIN (4 channels), I²C (10 channels), and 12-channel 16-bit TAU timers for embedded control in motor drives and sensor nodes.

For engineers reviewing the R5F104PKAFB#10 datasheet, R5F104PKAFB#10 pinout, R5F104PKAFB#10 application, or R5F104PKAFB#10 equivalent, key selection considerations include its G-grade temperature rating, LFQFP-100 package with 0.5 mm pitch, integrated event link controller (ELC) for peripheral synchronization, background data flash rewriting (BGO), and hardware DTC for zero-CPU-load data transfers - all critical for real-time industrial firmware design.

Technical Context

The R5F104PKAFB#10 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-power mode). It includes on-chip high-accuracy ±1.0% oscillator (1–64 MHz selectable) and dedicated low-speed oscillator for watchdog timer operation.

Peripheral integration centers on deterministic real-time control: Event Link Controller (ELC) enables direct hardware linking of 26 event sources to peripherals without CPU intervention; Data Transfer Controller (DTC) supports block, repeat, and chain transfer modes triggered by interrupts; and Real-Time Clock (RTC) provides calendar support up to 99 years with alarm and clock correction functions.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104PKAFB#10?

The R5F104PKAFB#10 operates at a maximum frequency of 32 MHz, delivering 44 DMIPS (Dhrystone MIPS) performance. This is achieved using the on-chip high-speed oscillator, which supports ±1.0% accuracy across 1.8–5.5 V and -40 to +105°C. The RL78 CPU core's 3-stage pipeline and optimized instruction set enable consistent throughput for real-time control tasks in the R5F104PKAFB#10.

Does the R5F104PKAFB#10 support background data flash rewriting (BGO), and what is the rated endurance?

Yes, the R5F104PKAFB#10 supports Background Operation (BGO) for data flash, allowing program execution from code flash while simultaneously rewriting data flash memory. Its data flash endurance is rated at 1,000,000 write/erase cycles (typical), with operation supported across the full 1.8–5.5 V supply range - enabling reliable parameter storage and firmware update staging in the R5F104PKAFB#10.

What package type and pin count does the R5F104PKAFB#10 use, and is thermal pad connection required?

The R5F104PKAFB#10 uses a 100-pin LFQFP package (14 × 14 mm body, 0.5 mm pitch) with an exposed thermal pad. While not strictly mandatory, Renesas recommends connecting the thermal pad to VSS for improved thermal dissipation and regulator stability - especially under sustained 32 MHz operation or ambient temperatures approaching +105°C in the R5F104PKAFB#10.

How many UART/LIN channels does the R5F104PKAFB#10 integrate, and are they hardware-LIN compliant?

The R5F104PKAFB#10 integrates four UART channels, each supporting LIN 2.0/2.1/2.2 protocol via built-in LIN break detection, sync field generation, and checksum calculation. All four UARTs are fully hardware-accelerated for LIN bus communication - eliminating bit-banging overhead and ensuring precise timing compliance for automotive and industrial sub-networks in the R5F104PKAFB#10.

What is the operating temperature grade of the R5F104PKAFB#10, and how does it impact industrial deployment?

The R5F104PKAFB#10 carries the 'G' grade designation, specifying operation from -40 to +105°C ambient temperature. This qualifies it for demanding industrial environments such as motor drives, PLC modules, and outdoor sensor enclosures where passive cooling or wide ambient swings occur - ensuring functional reliability without derating or forced airflow in the R5F104PKAFB#10.
