FAQ

What is the maximum operating frequency of the R5F11EB8AFP#30 using its internal oscillator?

The R5F11EB8AFP#30 supports a high-speed on-chip oscillator up to 24 MHz with ±2% accuracy across -40°C to +85°C and 2.7–5.5 V supply. This enables a minimum instruction execution time of 0.04167 µs, making it suitable for real-time control tasks without external clock components. The R5F11EB8AFP#30 also supports external crystal oscillation up to 20 MHz via X1/X2 pins for higher precision timing.

Does the R5F11EB8AFP#30 support in-system programming and debugging?

Yes, the R5F11EB8AFP#30 includes an on-chip debug function and flash self-programming capability enabled by the flash shield window function. It supports programming and debugging via TOOL0, TOOLRxD, and TOOLTxD pins (P40, P50, P51). However, Renesas cautions against using the debug function in mass-produced units due to potential flash endurance impact - the R5F11EB8AFP#30 is intended for development and evaluation use only in final products.

How many analog input channels does the R5F11EB8AFP#30 support, and what is their resolution?

The R5F11EB8AFP#30 integrates a 10-bit A/D converter with 12 analog input channels: ANI0 through ANI7 (on P20–P27) and ANI16 through ANI19 (on P01, P00, P147, P120). It provides an internal 1.45 V reference voltage and supports ratiometric measurement using AVREFP and AVREFM pins. Temperature sensor output is accessible only in HS (high-speed main) mode per the datasheet specification.

What low-power modes are available on the R5F11EB8AFP#30, and what are their typical current draws?

The R5F11EB8AFP#30 offers HALT (0.52 µA), STOP (0.37 µA), and SNOOZE modes - all specified at VDD = 2.7–5.5 V and TA = -40°C to +85°C. In STOP mode, the CPU, flash, and most peripherals halt while RAM and certain wake-up sources remain active. The R5F11EB8AFP#30 achieves these ultra-low currents without external circuitry, enabling multi-year operation on coin cells or energy-harvesting sources.

Can the R5F11EB8AFP#30 drive standard LEDs or small relays directly from its GPIO pins?

Yes, the R5F11EB8AFP#30 GPIO pins support up to 20 mA sink current (IOL1) per selected pin (e.g., P00, P10–P17, P30, P31) and 40 mA total sink per group, with VOL1 ≤ 0.7 V at 8.5 mA - sufficient for driving standard 2 mA LEDs or small 5 V reed relays with appropriate series resistors. However, P20–P27 are limited to 0.4 mA sink, so those pins must not be used for direct actuation. The R5F11EB8AFP#30 does not support high-side drive; external transistors or drivers are needed for loads requiring source current.
