FAQ
What is the maximum operating frequency and corresponding performance of the R5F100BGDNA#U0?
The R5F100BGDNA#U0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F100BGDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100BGDNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for secure firmware protection. Self-programming with boot swap functionality enables safe dual-bank firmware updates without external programmers.
What are the key low-power modes supported by the R5F100BGDNA#U0 and their typical current consumption?
The R5F100BGDNA#U0 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE modes. In STOP mode, only the real-time clock and low-voltage detector remain operational, enabling multi-year battery life in intermittent-sensing applications.
Can the R5F100BGDNA#U0 interface directly with 1.8 V or 2.5 V peripheral ICs?
Yes, the R5F100BGDNA#U0 supports different-potential interface operation: its I/O ports can be configured to interface directly with 1.8 V, 2.5 V, or 3.0 V logic devices without level shifters, thanks to independent input threshold control and selectable pull-up resistors.
What is the endurance and voltage range for data flash writes on the R5F100BGDNA#U0?
The R5F100BGDNA#U0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports rewriting across the full supply range of 1.8 V to 5.5 V - enabling robust parameter storage and field firmware updates even in brown-out conditions.
