The R5F101GCANA#00 contains 128 KB of code flash memory and zero data flash memory. This configuration is intended for applications where firmware is fixed after programming and no runtime parameter storage is required. The code flash supports 1 KB block erasure and includes security features like block erase prohibition and flash shield window functionality to prevent unauthorized access or modification of the program code in the R5F101GCANA#00.
Does the R5F101GCANA#00 support LIN bus communication?
Yes, the R5F101GCANA#00 supports LIN bus communication through its UART peripheral, which includes LIN-mode functionality compliant with LIN 2.x specifications. The UART module can generate and decode LIN headers and checksums in hardware, reducing CPU overhead. This capability is confirmed in the RL78/G13 datasheet section on serial interfaces and applies directly to the R5F101GCANA#00 as a member of the G13 family with UART channel support.
What is the operating temperature range for the R5F101GCANA#00?
The R5F101GCANA#00 is rated for industrial operation from –40°C to +85°C. This temperature grade is indicated by the "D" suffix in the part numbering convention defined in the RL78/G13 datasheet. The device meets full electrical specifications across this range without derating and includes on-chip voltage detector (LVD) with 14 selectable threshold levels to ensure reliable operation during voltage transients at temperature extremes in the R5F101GCANA#00.
Can the R5F101GCANA#00 operate from a single 3.3 V supply?
Yes, the R5F101GCANA#00 operates from a single supply voltage ranging from 1.6 V to 5.5 V, fully covering standard 3.3 V nominal systems. At 3.3 V, it achieves its rated 32 MHz maximum frequency and 41 DMIPS performance while maintaining full peripheral functionality, including 10-bit ADC accuracy and real-time clock stability. All I/O pins are compatible with 3.3 V logic levels, and the device supports different-potential interface capability for mixed-voltage system integration in the R5F101GCANA#00.
