Renesas R5F104FAGFP#30

Overview

R5F104FAGFP#30 from Renesas is a 44-pin LQFP-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade temperature support (−40°C to +105°C). It delivers 44 DMIPS at 32 MHz, features ultra-low power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and on-chip RTC for embedded control in HVAC, motor drives, and smart sensors.

For engineers reviewing the R5F104FAGFP#30 datasheet, R5F104FAGFP#30 pinout, R5F104FAGFP#30 application, or R5F104FAGFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, G-grade industrial temp rating, 96 KB/12 KB Flash/RAM configuration, integrated data flash (8 KB), and support for background data flash rewriting (BGO) without halting CPU execution.

Technical Context

The R5F104FAGFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It uses a segmented memory map with 1 MB address space and four register banks, enabling efficient context switching in real-time interrupt-driven applications.

Its peripheral subsystem includes an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/chain transfer modes, and dual-voltage I/O (1.8/2.5/3.0 V interface compatibility), allowing direct connection to mixed-voltage logic without level shifters.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for R5F104FAGFP#30?

The R5F104FAGFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS. Its minimum instruction execution time is 0.03125 µs at this frequency, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. The RL78 core's 3-stage pipeline ensures deterministic timing critical for motor control loops and real-time communication stacks in the R5F104FAGFP#30.

Does R5F104FAGFP#30 support in-system programming and secure firmware updates?

Yes, the R5F104FAGFP#30 supports full in-system programming via on-chip debug interface and includes flash shield window protection to prevent unauthorized read-out of secured code regions. It enables self-programming with boot swapping and background data flash rewriting (BGO), allowing firmware updates without halting CPU execution - essential for reliable over-the-air updates in deployed R5F104FAGFP#30-based devices.

What analog peripherals are integrated into R5F104FAGFP#30, and what are their key specifications?

The R5F104FAGFP#30 integrates a 10-bit resolution ADC with 16 analog input channels (ANI0–ANI15), internal 1.45 V reference voltage, and on-die temperature sensor. It supports VDD-referenced or internal-reference operation across 1.6–5.5 V supply range. No D/A converter or analog comparator is included in this variant. These analog capabilities directly serve sensor interfacing and closed-loop control tasks in the R5F104FAGFP#30.

How does the Event Link Controller (ELC) enhance real-time performance in R5F104FAGFP#30?

The ELC in R5F104FAGFP#30 enables hardware-level linking of up to 26 peripheral events - such as ADC end-of-conversion triggering DTC transfers or timer overflow initiating GPIO toggles - without CPU intervention. This eliminates ISR latency and software overhead, improving deterministic response in time-critical applications like motor commutation or synchronized sensor sampling within the R5F104FAGFP#30.

What packaging and compliance information applies to R5F104FAGFP#30?

R5F104FAGFP#30 is supplied in a 44-pin LQFP package (10 × 10 mm, 0.8 mm pitch), RoHS-compliant, lead-free, and qualified for industrial temperature range (−40°C to +105°C). The Renesas code PLQP0044GC-A denotes this specific variant. It requires a 0.47–1 µF REGC bypass capacitor and supports standard reflow profiles per J-STD-020 - all verified for production use in the R5F104FAGFP#30.
