Renesas R5F104PGAFB#30

Overview

R5F104PGAFB#30 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (0.60 μA RTC+LVD). It targets battery-powered industrial sensors and motor control interfaces requiring integrated analog peripherals and deterministic real-time response.

For engineers reviewing the R5F104PGAFB#30 datasheet, R5F104PGAFB#30 pinout, R5F104PGAFB#30 application, or R5F104PGAFB#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, 96 KB/12 KB/8 KB memory configuration, -40°C to +105°C industrial temperature rating, and support for multiple serial interfaces (UART×4, I²C×10, CSI×8), 16-bit timers (12 channels), and 20-channel 10-bit ADC.

Technical Context

The R5F104PGAFB#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 integrates Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) supporting block, repeat, and chain transfers activated by 19–26 event sources.

Its analog subsystem includes a 10-bit ADC with 20 input channels, internal 1.45 V reference and temperature sensor, dual 8-bit DACs (0–VDD output), and up to two comparators with window/high-speed/low-speed modes. Power management features HALT, STOP, and SNOOZE modes, on-chip POR/LVD, and ±1.0% accuracy high-speed oscillator (1–64 MHz selectable).

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104PGAFB#30?

The R5F104PGAFB#30 achieves a maximum operating frequency of 32 MHz, delivering 44 DMIPS performance. This rating is measured under standard conditions (VDD = 3.3 V, TA = 25°C) using the EEMBC CoreMark benchmark. The RL78 core's 3-stage pipeline and optimized instruction set enable consistent throughput across its full 1.6–5.5 V supply range.

Does the R5F104PGAFB#30 support hardware-accelerated data movement between peripherals without CPU intervention?

Yes, the R5F104PGAFB#30 integrates both the Data Transfer Controller (DTC) and Event Link Controller (ELC). The DTC handles block, repeat, and chain transfers triggered by interrupt sources, while the ELC links 19–26 event signals (e.g., ADC end-of-conversion) directly to peripheral functions (e.g., DTC start), enabling fully autonomous data flow - critical for deterministic real-time systems.

What are the analog capabilities of the R5F104PGAFB#30, particularly regarding ADC and DAC?

The R5F104PGAFB#30 includes a 10-bit successive-approximation ADC with up to 20 input channels, internal 1.45 V reference voltage, and integrated temperature sensor. It also features two independent 8-bit DACs with 0–VDD output range and real-time update capability - enabling precise analog signal generation for control loops or calibration references without external components.

Is the R5F104PGAFB#30 qualified for industrial temperature operation, and what is its specified range?

Yes, the R5F104PGAFB#30 is qualified for industrial applications with a specified ambient operating temperature range of -40°C to +105°C (G grade). This rating is validated per JEDEC JESD22-A108 and applies across the full 1.6–5.5 V supply range, ensuring reliable operation in harsh environments such as factory automation and outdoor infrastructure.

How does the R5F104PGAFB#30 manage ultra-low-power operation, and what is its lowest active current draw?

The R5F104PGAFB#30 achieves 66 μA/MHz active current at 32 MHz and reduces to 0.60 μA in STOP mode with only RTC and LVD active. This is enabled by segmented power domains, dynamic voltage scaling, and multiple low-power modes (HALT, STOP, SNOOZE). The 0.60 μA figure is measured at VDD = 3.3 V, TA = 25°C, with RTC running from 32.768 kHz crystal and LVD monitoring enabled.
