Does the R5F100LHAFA#X0 include on-chip data flash, and what are its endurance and voltage requirements?
Yes, the R5F100LHAFA#X0 includes 8 KB of on-chip data flash memory. It supports 1,000,000 write/erase cycles (typical) and operates with rewrite voltage ranging from VDD = 1.8 V to 5.5 V. Background operation (BGO) allows CPU execution from program memory during data flash writes, enabling seamless logging and configuration updates without halting application code.
What low-power modes does the R5F100LHAFA#X0 support, and what is its lowest active current consumption?
The R5F100LHAFA#X0 supports HALT, STOP, and SNOOZE modes. Its lowest active-mode current is 66 μA per MHz at 32 MHz operation. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - making it suitable for decade-long battery operation in wireless sensor endpoints. Wake-up sources include external interrupts, RTC alarms, and LVD events.
Is the R5F100LHAFA#X0 qualified for industrial temperature operation, and what grade does it carry?
Yes, the R5F100LHAFA#X0 carries the 'G' grade designation, qualifying it for continuous operation from −40°C to +105°C. This rating meets industrial and extended-temperature automotive requirements, including under-hood and factory-floor deployments. The device undergoes screening and characterization across this full range for timing, voltage, and peripheral functionality.
