Renesas R5F100GGANA#W0

Overview

R5F100GGANA#W0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.

For engineers reviewing the R5F100GGANA#W0 datasheet, R5F100GGANA#W0 pinout, R5F100GGANA#W0 application, or R5F100GGANA#W0 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated 10-bit ADC (26 channels), real-time clock with calendar, and hardware UART/SPI/I²C interfaces supporting LIN-bus and background data flash rewriting.

Technical Context

The R5F100GGANA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, 16-bit timers (12 channels), watchdog timer, and DMA controller with 4 channels for efficient peripheral-to-memory transfers.

Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14 selectable voltage levels), and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz). The device supports self-programming with boot swap and flash shield window functions, and executes instructions from program memory during background data flash rewriting (BGO).

FAQ

What is the maximum operating frequency and performance of the R5F100GGANA#W0?

The R5F100GGANA#W0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this through a 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C. This enables deterministic real-time control in applications such as motor commutation and sensor fusion where cycle count predictability matters.

Does the R5F100GGANA#W0 support data flash rewriting during program execution?

Yes, the R5F100GGANA#W0 supports background operation (BGO) for data flash rewriting. While executing code from program memory, it can simultaneously rewrite its 8 KB data flash memory - rated for 1,000,000 write cycles at VDD = 1.8–5.5 V. This enables seamless firmware parameter updates without halting application logic.

What is the operating temperature range certified for the R5F100GGANA#W0?

The R5F100GGANA#W0 is qualified for industrial applications with an operating ambient temperature range of –40°C to +105°C (G-grade). This rating is confirmed in the RL78/G13 datasheet Rev.3.80 and applies specifically to part numbers ending in 'G', including R5F100GGANA#W0 - making it suitable for under-hood automotive modules and factory-floor controllers.

How many analog input channels does the R5F100GGANA#W0 support?

The R5F100GGANA#W0 supports up to 26 analog input channels (ANI0–ANI25) for its 10-bit A/D converter. These channels are distributed across multiple ports (P20–P27, P30–P37, P40–P47, etc.) and share internal resources including the 1.45 V reference voltage and temperature sensor - all accessible without external components.

What package type and pin count does the R5F100GGANA#W0 use?

The R5F100GGANA#W0 uses a 48-pin HWQFN package (7 × 7 mm, 0.5-mm pitch), identified by the 'NA' suffix in the part number and '#W0' embossed tape packaging code. This thermally enhanced, space-efficient package supports reflow soldering and provides 39 general-purpose I/O pins plus dedicated power, clock, and reset terminals.
