Renesas R5F100EGGNA#U0

Overview

R5F100EGGNA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for ultra-low-power industrial control and sensor interface applications operating from 1.6 V to 5.5 V.

For engineers reviewing the R5F100EGGNA#U0 datasheet, R5F100EGGNA#U0 pinout, R5F100EGGNA#U0 application, or R5F100EGGNA#U0 equivalent, key selection criteria include its 0.57 μA STOP mode current, 66 μA/MHz active power, integrated LIN-capable UART, hardware multiplier/divider, and -40°C to +105°C industrial temperature grade (G-suffix).

Technical Context

The R5F100EGGNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed subsystem clock for RTC and watchdog.

Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI/SPI channels, DMA controller (4-channel), and background operation (BGO) for concurrent data flash rewriting and program execution - enabling deterministic real-time response in battery-powered systems.

FAQ

What is the maximum operating frequency of the R5F100EGGNA#U0?

The R5F100EGGNA#U0 supports a maximum system clock frequency of 32 MHz using the high-speed on-chip oscillator. This yields 41 DMIPS performance and a minimum instruction execution time of 0.03125 μs. External clock sources up to 20 MHz are also supported via EXCLK, and the subsystem clock runs at 32.768 kHz for RTC operation - all verified in the R01DS0131EJ0380 datasheet.

Does the R5F100EGGNA#U0 include an integrated temperature sensor?

Yes, the R5F100EGGNA#U0 includes an on-chip temperature sensor usable only in HS (high-speed main) mode, as specified in the RL78/G13 datasheet. It provides calibrated readings referenced to the internal 1.45 V bandgap voltage, enabling ambient temperature monitoring without external components - a feature confirmed in Section 1.1 "Features" and Table 1-1 memory mapping.

What packaging and moisture sensitivity level (MSL) does the R5F100EGGNA#U0 have?

The R5F100EGGNA#U0 uses a 40-pin HWQFN package (6 × 6 mm, 0.5-mm pitch) with #U0 suffix indicating tray packaging. Its moisture sensitivity level is MSL 3 per J-STD-020, requiring bake conditioning if exposed beyond floor life - confirmed by Renesas packaging specification PWQN0040KC-A and datasheet revision 3.80.

Can the R5F100EGGNA#U0 operate from a 1.8 V supply?

Yes, the R5F100EGGNA#U0 operates across a 1.6 V to 5.5 V supply range, fully supporting 1.8 V operation. At this voltage, all peripherals - including 10-bit ADC, RTC, and LIN-capable UART - remain functional per datasheet electrical characteristics (VDD = 1.6–5.5 V, TA = –40 to +105°C), enabling direct interface with 1.8 V logic families.

How many analog input channels does the R5F100EGGNA#U0 support?

The R5F100EGGNA#U0 supports up to 26 analog input channels (ANI0–ANI25), with 8 dedicated analog pins (P20–P27) accessible in the 40-pin HWQFN package. The remaining channels are multiplexed onto other I/O ports - confirmed in the "A/D converter" section of the datasheet and validated against the R5F100EGx pin configuration table.
