Renesas R5F104GGANA#U0

Overview

R5F104GGANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 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, integrates an 8-bit D/A converter, 10-bit A/D converter (20-channel), real-time clock, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode), targeting battery-powered industrial sensor nodes and motor control interfaces.

For engineers reviewing the R5F104GGANA#U0 datasheet, R5F104GGANA#U0 pinout, R5F104GGANA#U0 application, or R5F104GGANA#U0 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) footprint, G-grade extended-temperature qualification, integrated event link controller (ELC) for peripheral coordination, and hardware data transfer controller (DTC) enabling zero-CPU-load memory moves during low-power operation.

Technical Context

The R5F104GGANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes, with on-chip LVD offering 14 selectable voltage detection levels and interrupt/reset options.

Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, watchdog timer, UART/UART-LIN (3 channels), CSI (3–8 channels), I²C (4–10 channels), and 19–26 configurable event signals routed via Event Link Controller (ELC) to synchronize peripheral actions without CPU intervention.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GGANA#U0?

The R5F104GGANA#U0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator (±1.0% accuracy across 1.8–5.5 V and −20°C to +85°C). The R5F104GGANA#U0 maintains this rating under full G-grade temperature range (−40°C to +105°C) with appropriate derating per Renesas datasheet conditions.

Does the R5F104GGANA#U0 support hardware debugging and programming in-system?

Yes, the R5F104GGANA#U0 supports full in-circuit debugging and programming via its dedicated TOOLRxD (P50) and TOOLTxD (P51) pins, compatible with Renesas E2 emulator and CS+ IDE. These pins also serve as UART channel 0, enabling simultaneous debug communication and application serial I/O when configured appropriately in the peripheral I/O redirection registers.

How many analog input channels and what resolution does the ADC in the R5F104GGANA#U0 provide?

The R5F104GGANA#U0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated pins like P20–P27 and multiplexed functions on P120/P147. It supports internal 1.45 V reference voltage and differential measurements using AVREFP/AVREFM, enabling precision sensor interfacing without external reference components.

What low-power modes are available on the R5F104GGANA#U0, and what is the lowest achievable current consumption?

The R5F104GGANA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.60 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current is validated across the full G-grade temperature range and enables decade-long battery operation in always-on sensor applications.

Is the R5F104GGANA#U0 pin-compatible with other RL78/G14 variants in the same package?

Yes, all RL78/G14 devices in the 48-pin HWQFN package-including R5F104GGANA#U0, R5F104GHANA#U0, and R5F104GLANA#U0-share identical pinouts and electrical characteristics. Function allocation (e.g., UART, ADC, timers) is consistent across variants; only flash/RAM capacities and supported peripheral counts differ, all managed transparently by firmware configuration.
