FAQ
What is the operating temperature range for the R5F100GDGNA#20?
The R5F100GDGNA#20 is rated for industrial operation from –40°C to +105°C, confirmed by the 'G' suffix in its part number per Renesas RL78/G13 documentation. This makes it suitable for under-hood automotive subsystems, factory-floor controllers, and outdoor metering equipment where ambient extremes are expected. The device maintains full specification compliance across this range, including flash programming voltage and ADC accuracy.
Does the R5F100GDGNA#20 support in-circuit debugging?
Yes, the R5F100GDGNA#20 includes full on-chip debug functionality compatible with Renesas E2 emulator and CS+ IDE. Debug access uses dedicated TOOLRxD/TOOLTxD pins (P11/P12), enabling breakpoints, watchpoints, and real-time variable inspection without halting peripheral operation. No external debug header is required - the interface is integrated into the standard 48-pin HWQFN footprint.
How many ADC channels does the R5F100GDGNA#20 support, and what is the resolution?
The R5F100GDGNA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), as specified in the RL78/G13 datasheet. It supports internal 1.45 V reference and external AVREFP/AVREFM inputs, enabling ratiometric measurements. Conversion time is 1.2 μs per sample at maximum clock, and the ADC operates across the full 1.6–5.5 V supply range.
Can the R5F100GDGNA#20 execute code while rewriting data flash memory?
Yes, the R5F100GDGNA#20 supports Background Operation (BGO) for data flash, allowing program execution from code flash while simultaneously rewriting data flash sectors. This capability is essential for over-the-air firmware updates and runtime parameter storage without interrupting real-time control loops - verified in Section 1.1 Features and Flash Self-Programming Library documentation.
What packaging and moisture sensitivity level (MSL) apply to the R5F100GDGNA#20?
The R5F100GDGNA#20 is supplied in a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad, per Renesas package code PWQN0048KB-A. Its moisture sensitivity level is MSL3, requiring bake conditioning if exposed to ambient >12 months after seal opening. The #20 suffix indicates embossed tape packaging per J-STD-020 standards.
