The R5F104MGGFB#30 operates at up to 32 MHz with its RL78 CPU core, achieving 44 DMIPS performance. This metric is measured under standard conditions per Renesas' benchmark methodology and reflects sustained integer throughput for typical control code, not peak burst capability.
Does the R5F104MGGFB#30 support hardware-based LIN bus communication?
Yes, the R5F104MGGFB#30 supports LIN 2.2 protocol natively through UART2, including automatic sync-break detection, checksum generation (classic and enhanced), and slave node response timing compliance - all implemented in hardware without CPU intervention.
What is the flash memory organization and security capability of the R5F104MGGFB#30?
The R5F104MGGFB#30 contains 256 KB of code flash organized in 1 KB blocks. It supports flash security features including block erase/write prohibition and flash shield window, preventing unauthorized access to protected regions during debug or field operation.
How does the R5F104MGGFB#30 manage power in battery-operated applications?
The R5F104MGGFB#30 achieves ultra-low power via multiple modes: STOP mode draws just 0.60 μA while maintaining RTC and LVD functionality, and HALT mode consumes 66 μA/MHz. Its 1.6–5.5 V operating range allows direct connection to primary lithium or coin-cell batteries without regulators.
Is the R5F104MGGFB#30 pin-compatible with other RL78/G14 variants in the same package?
