Renesas R5F104GGDFB#30

Overview

R5F104GGDFB#30 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.

For engineers reviewing the R5F104GGDFB#30 datasheet, R5F104GGDFB#30 pinout, R5F104GGDFB#30 application, or R5F104GGDFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 0.5 mm pitch LFQFP package, integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.

Technical Context

The R5F104GGDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a Data Transfer Controller (DTC) with chain transfer and block/normal/repeat modes, activated by 19–26 event sources via the Event Link Controller (ELC).

It features a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8-bit D/A converter with real-time output, two comparators (high/low-speed and window modes), and 16-bit Timer Array Unit (TAU) with up to 8 channels plus dedicated RTC, watchdog, and interval timers - all operating within the same low-voltage, low-power envelope.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F104GGDFB#30?

The R5F104GGDFB#30 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C), delivering 44 DMIPS. Its minimum instruction execution time is 0.03125 µs at 32 MHz, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This frequency agility enables both high-throughput control loops and extended battery life in the same design.

Does the R5F104GGDFB#30 support in-system programming and secure firmware updates?

Yes, the R5F104GGDFB#30 supports full in-system programming via on-chip debug interface and includes flash security features such as block erase/write prohibition and flash shield window. It enables safe field updates using boot swapping - allowing validated new firmware to be written to a secondary region while the primary region remains operational - a critical capability for maintaining uptime in deployed R5F104GGDFB#30-based systems.

How many serial communication interfaces does the R5F104GGDFB#30 integrate, and what protocols are supported?

The R5F104GGDFB#30 integrates up to 4 UART/LIN channels, 3–8 CSI (SPI-compatible) channels, and 4–10 I²C/simplified I²C channels. All UARTs support LIN 2.2 physical layer features including automatic sync-break detection and baud rate adjustment - enabling direct connection to LIN bus without external transceivers in basic node configurations. The CSI modules operate in master/slave mode with programmable clock polarity and phase.

What analog peripherals are included in the R5F104GGDFB#30, and how are they calibrated?

The R5F104GGDFB#30 includes a 10-bit A/D converter with 20 input channels, an 8-bit D/A converter with up to two outputs, two analog comparators, and an on-chip temperature sensor. The ADC uses an internal 1.45 V reference voltage, factory-trimmed for ±1% accuracy across voltage and temperature. The temperature sensor output is digitized by the same ADC and calibrated against known reference points in ROM - eliminating need for external calibration in most R5F104GGDFB#30 implementations.

Is the R5F104GGDFB#30 pin-compatible with other RL78/G14 variants in the same package?

Yes, all RL78/G14 devices in the 48-pin LFQFP (FB) package - including R5F104GGDFB#30, R5F104GHDFB#30, and R5F104GLAFB - share identical pinouts and electrical characteristics. Memory size differences (96 KB vs. 128 KB vs. 384 KB) and minor peripheral enablement (e.g., additional TAU channels in higher-flash variants) do not affect pin function mapping or PCB layout - enabling scalable design reuse across performance tiers within the same R5F104GGDFB#30 footprint.
