Product details
Overview
R5F104PKGFB#30 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 512 KB flash, 48 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V at -40°C to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 ch), and real-time clock for embedded control in harsh environments.
For engineers reviewing the R5F104PKGFB#30 datasheet, R5F104PKGFB#30 pinout, R5F104PKGFB#30 application, or R5F104PKGFB#30 equivalent, key selection considerations include its 100-pin LFQFP-0.5 mm package, industrial temperature rating (−40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation capability, and support for LIN-bus via UART peripherals.
Technical Context
The R5F104PKGFB#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 1 MB address space.
Its peripheral set includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat/normal transfer modes, and dual-voltage interface I/O supporting 1.8/2.5/3.0 V logic levels - enabling direct interfacing with low-voltage sensors and communication ICs without level shifters.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104PKGFB#30?
The R5F104PKGFB#30 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports configurable instruction timing - from 0.03125 µs (high-speed mode) down to 30.5 µs (ultra-low-speed mode at 32.768 kHz) - enabling dynamic trade-offs between throughput and power in real-time applications.
Does the R5F104PKGFB#30 support LIN bus communication, and how is it implemented?
Yes, the R5F104PKGFB#30 supports LIN bus communication through its UART peripherals, which include LIN-bus compliant features such as break detection, sync field handling, and checksum calculation. The UART modules can be configured as LIN master or slave nodes, and the Event Link Controller (ELC) allows hardware-synchronized responses to LIN frame events - reducing CPU overhead and improving protocol timing accuracy.
What are the data flash endurance and rewrite voltage specifications for the R5F104PKGFB#30?
The R5F104PKGFB#30 includes 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) with operation supported across the full supply range of VDD = 1.8 V to 5.5 V. Background operation (BGO) allows CPU code execution from program memory during data flash writes, ensuring deterministic real-time behavior - critical for secure firmware updates and parameter logging in industrial systems.
How does the R5F104PKGFB#30 manage power in low-energy applications?
The R5F104PKGFB#30 achieves ultra-low power operation with 66 μA/MHz active current and just 0.60 μA in STOP mode with RTC and LVD enabled. It offers HALT, STOP, and SNOOZE modes, plus an on-chip voltage detector (LVD) with 14 programmable thresholds. These features allow precise brown-out protection and energy-aware wake-up strategies - essential for battery-powered sensors and energy-harvesting devices.
Is the R5F104PKGFB#30 pin-compatible with other RL78/G14 variants in the same package?
No - the R5F104PKGFB#30 is not universally pin-compatible across all RL78/G14 variants, even within the same 100-pin LFQFP package. Pin functions (e.g., peripheral assignments like UART, ADC, or timer channels) vary by flash size and feature set. Engineers must consult the specific variant's pin configuration table and verify peripheral mapping in the R01DS0053EJ0370 datasheet before assuming interchangeability.
