Renesas R5F104LGGFP#30

Overview

R5F104LGGFP#30 from Renesas is a 64-pin LFQFP, 512 KB flash, 8 KB data flash, 20 KB RAM RL78/G14 16-bit MCU 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 motor control and sensor-based HMI systems.

For engineers reviewing the R5F104LGGFP#30 datasheet, R5F104LGGFP#30 pinout, R5F104LGGFP#30 application, or R5F104LGGFP#30 equivalent, key selection considerations include its -40°C to +105°C industrial-grade temperature rating (G suffix), 64-pin 0.5 mm pitch LFQFP package, integrated RTC with calendar/alarm, and dual 10-bit A/D converters with up to 20 input channels.

Technical Context

The R5F104LGGFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates an Event Link Controller (ELC) for hardware-triggered peripheral chaining and a Data Transfer Controller (DTC) enabling block/repeat transfers without CPU intervention.

Its mixed-signal subsystem includes a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, dual 8-bit D/A outputs (0–VDD), two comparators with window/high-speed/low-speed modes, and a real-time clock with 99-year calendar, alarm, and clock correction-enabling autonomous timing-critical functions in battery-backed applications.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F104LGGFP#30?

The R5F104LGGFP#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. Its instruction execution time scales dynamically from 0.03125 µs (at 32 MHz) down to 30.5 µs (at 32.768 kHz), enabling precise trade-offs between speed and power consumption in real-time control loops. This performance level is validated across the full -40°C to +105°C industrial temperature range.

Does the R5F104LGGFP#30 support hardware debugging and programming in-system?

Yes, the R5F104LGGFP#30 includes a fully integrated on-chip debug function compliant with Renesas E1/E20 emulators. It supports non-intrusive breakpoints, real-time variable watch, and flash programming via the single-wire debug interface (SWD) using pins P137 (INTP0) and P121 (X1) in debug mode. The R5F104LGGFP#30 also enables secure self-programming with boot swapping and flash shield window protection during field updates.

How many analog-to-digital converter channels does the R5F104LGGFP#30 provide, and what are their key specifications?

The R5F104LGGFP#30 integrates a 10-bit resolution A/D converter with up to 20 analog input channels, operating across the full 1.6–5.5 V supply range. It features an internal 1.45 V reference voltage and an integrated temperature sensor, enabling accurate ambient temperature measurement without external components. Conversion time is programmable from 14 to 22 clock cycles, supporting sampling rates up to 1.25 MSPS when using the 32 MHz system clock.

What packaging and lead pitch does the R5F104LGGFP#30 use, and are there thermal considerations?

The R5F104LGGFP#30 uses a 64-pin LFQFP package with 10 × 10 mm body dimensions and 0.5 mm lead pitch. Unlike HWQFN variants, it lacks an exposed die pad, so thermal dissipation relies solely on PCB copper area under the package and standard trace routing. The REGC pin must be decoupled to VSS with a 0.47–1 µF capacitor to ensure stable internal voltage regulation-critical for analog accuracy and low-power mode stability across temperature.

Can the R5F104LGGFP#30 operate reliably in extended temperature environments, and what qualification supports this?

Yes, the R5F104LGGFP#30 is rated for continuous operation from -40°C to +105°C, indicated by the 'G' suffix in its part number. This industrial-grade qualification is verified per JEDEC JESD22-A104 (temperature cycling) and JESD22-A108 (high-temperature operating life), ensuring reliability in motor drives, factory automation controllers, and outdoor metering equipment where ambient temperatures exceed standard commercial limits.
