FAQ
What is the maximum operating frequency of the R5F1214AANA#00?
The R5F1214AANA#00 supports a maximum CPU operating frequency of 16 MHz using its high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.0625 μs. 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 R5F1214AANA#00 support in-system programming without external hardware?
Yes, the R5F1214AANA#00 supports on-chip debug and self-programming via its TOOL0/TOOLRxD/TOOLTxD pins. No external programmer is required for firmware updates in production or field service, provided the application reserves the necessary flash sectors and configures the flash shield window function appropriately.
How many capacitive touch channels does the R5F1214AANA#00 support?
The R5F1214AANA#00 integrates a 15-channel 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 pins selected from the 15 available CTSU-capable I/Os.
What is the data flash endurance specification for the R5F1214AANA#00?
The R5F1214AANA#00 specifies 1,000,000 write/erase cycles (typical) for its 1 KB data flash memory. Each rewrite operates on 32-bit units, and the memory is rated for full endurance across the full operating voltage range of 2.4 V to 5.5 V.
Is background operation (BGO) supported during data flash rewriting on the R5F1214AANA#00?
No, background operation (BGO) is not supported on the R5F1214AANA#00. During data flash rewriting, instruction execution from code flash memory is halted. Applications must manage timing carefully-using STOP mode or HALT mode during writes-or implement dual-bank strategies if continuous execution is required.
