Does the R5F104ACGSP#30 support hardware LIN bus communication?

Yes, the R5F104ACGSP#30 supports hardware LIN bus communication through its UART peripherals, which include automatic sync-break detection, checksum generation, and identifier filtering compliant with LIN 2.x specifications. This capability is implemented in UART channels such as UART2 (P13/P14) and UART0 (P50/P51), allowing the R5F104ACGSP#30 to serve as a LIN slave node without external transceivers or bit-banging overhead.

What are the memory resources available on the R5F104ACGSP#30?

The R5F104ACGSP#30 integrates 16 KB of code flash memory, 4 KB of data flash memory, and 2.5 KB of on-chip RAM. The data flash supports background operation (BGO), enabling concurrent program execution and data logging, and guarantees 1,000,000 write cycles at 1.8–5.5 V. These memory resources are optimized for compact firmware deployments in space-constrained industrial and appliance applications using the R5F104ACGSP#30.

What is the operating temperature range and package type of the R5F104ACGSP#30?

The R5F104ACGSP#30 is rated for industrial operation from -40 to +105°C (G-grade) and is housed in a 30-pin LSSOP package with 0.65 mm pitch (7.62 mm × 5.6 mm).
