FAQ
What is the maximum operating frequency of the R5F11EBAAFP#70?
The R5F11EBAAFP#70 supports a maximum high-speed on-chip oscillator frequency of 24 MHz and a maximum external crystal oscillator frequency of 20 MHz. At 24 MHz operation, the minimum instruction execution time is 0.04167 µs. The device also supports lower-frequency modes (1–8 MHz) for ultra-low-power applications, with the low-speed on-chip oscillator running at 15 kHz typical for watchdog and interval timing.
Does the R5F11EBAAFP#70 include an internal temperature sensor?
Yes, the R5F11EBAAFP#70 includes an internal temperature sensor that is selectable only in HS (high-speed main) mode. It operates alongside the 10-bit ADC and internal 1.45 V reference voltage, enabling on-die thermal monitoring without external components-useful for ambient temperature compensation in sensor applications.
What are the supported serial communication interfaces on the R5F11EBAAFP#70?
The R5F11EBAAFP#70 supports two UART channels (UART0 and UART1), one simplified SPI interface (labeled CSI in documentation), and one simplified I²C interface. UART0 uses P50/P51 for RxD0/TxD0 and supports tool connectivity (TOOLRxD/TOOLTxD), while UART1 uses P00/P01 for RxD1/TxD1-enabling simultaneous debug and application communication.
How many analog input channels does the R5F11EBAAFP#70 support?
The R5F11EBAAFP#70 supports 12 analog input channels: ANI0 through ANI3 (on P20–P23), plus ANI16 through ANI19 (on P01, P00, P147, and P120). These channels feed into the 8/10-bit resolution A/D converter, which operates across the full 2.7–5.5 V supply range and supports internal reference voltage (1.45 V) and temperature sensor inputs.
What power-saving modes are available on the R5F11EBAAFP#70?
The R5F11EBAAFP#70 provides three ultra-low-power operating modes: HALT mode (CPU stopped, peripherals active), STOP mode (CPU and most peripherals halted, ~0.52 µA typical current), and SNOOZE mode (selected peripherals remain active during low-power CPU sleep). All modes retain RAM content and support wake-up via interrupts, timers, or external events-enabling optimized energy management in battery-powered systems.
