FAQ
What is the maximum operating frequency of the R5F1216AASP#50?
The R5F1216AASP#50 supports a maximum system clock of 16 MHz using its high-speed on-chip oscillator. Instruction execution time can be as fast as 0.0625 μs at this frequency. The device also supports lower-frequency operation down to 32.768 kHz for ultra-low-power RTC and standby modes, with corresponding instruction times up to 30.5 μs.
Does the R5F1216AASP#50 support background data flash rewriting?
No, the R5F1216AASP#50 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, the CPU cannot execute instructions from code flash memory. Firmware must enter a safe state-such as HALT mode-or manage execution from RAM to avoid interruption.
How many touch sensing channels does the R5F1216AASP#50 provide?
The R5F1216AASP#50 provides 15 dedicated channels for the capacitive touch sensing unit (CTSU). It supports both self-capacitance (up to 15 independent keys) and mutual capacitance (up to 16 keys in matrix configuration) using configurable transmit/receive pin assignments from the same 15-pin pool.
What debug interface does the R5F1216AASP#50 use?
The R5F1216AASP#50 uses the on-chip debug interface accessible via the TOOL0, TOOLRxD, and TOOLTxD pins in its 20-pin LSSOP package. This interface supports full debugging, programming, and real-time trace without requiring external JTAG adapters-enabling cost-effective development and field firmware updates.
Is the R5F1216AASP#50 pin-compatible with other RL78/G16 variants in LSSOP packages?
Yes, the R5F1216AASP#50 shares identical pinout and electrical characteristics with all other 20-pin LSSOP variants in the RL78/G16 family-including R5F1216CASP#50 and R5F1216AGSP#50-enabling drop-in replacement for flash size or temperature grade changes without PCB modification.
