FAQ
What is the maximum operating frequency and corresponding performance of the R5F1054AANA#20?
The R5F1054AANA#20 operates up to 24 MHz using its high-speed on-chip oscillator, achieving 33 DMIPS performance. Its minimum instruction execution time is 0.04167 μs under this condition. The device also supports lower-frequency modes including 15 kHz low-speed oscillator operation for ultra-low-power standby states, maintaining full functionality across its 1.6–5.5 V supply range.
Does the R5F1054AANA#20 support in-system programming and secure firmware updates?
Yes, the R5F1054AANA#20 includes self-programming capability with boot swap function and flash shield window protection. These features enable safe field firmware updates with rollback capability and prevent unauthorized access to protected code sections. Data flash memory supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for logging or configuration storage during runtime.
How many analog input channels does the R5F1054AANA#20 support, and what is the ADC resolution?
The R5F1054AANA#20 supports 8 external analog input channels (ANI0–ANI3, ANI18, ANI20–ANI22) with 10-bit resolution. It also includes an internal temperature sensor and 1.45 V reference voltage generator. The ADC operates across the full 1.6–5.5 V supply range and supports differential measurement using AVREFP/AVREFM pins for improved noise immunity in precision sensing applications.
What serial communication interfaces are integrated into the R5F1054AANA#20?
The R5F1054AANA#20 integrates two UART channels, two simplified SPI (CSI) channels, and one simplified I²C channel. All interfaces support peripheral I/O redirection via PIOR registers, enabling flexible pin assignment. The UARTs include LIN-compliant features, and the CSI modules support master/slave operation with configurable clock polarity and phase - suitable for connecting displays, sensors, and wireless modules without external level shifters.
What low-power modes are available on the R5F1054AANA#20, and what is the typical current draw in each?
The R5F1054AANA#20 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode, it draws just 0.64 μA (typical) with only the LVD active - ideal for extended sleep periods. HALT mode consumes 58.3 μA/MHz during active operation, and SNOOZE allows selected peripherals like UART or ADC to run while CPU remains halted. Wake-up sources include external interrupts, key return inputs, and timer events - all configurable without CPU intervention.
