The R5F100GEGFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This enables real-time execution of control algorithms, communication stack handling, and sensor data processing without external acceleration. Its 3-stage pipeline RL78 core ensures consistent instruction timing critical for deterministic motor control and power conversion applications.
Does the R5F100GEGFB#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F100GEGFB#V0 supports LIN bus communication through UART0, which is LIN 2.2–compliant at the physical layer. It uses standard UART registers with optional LIN-specific features like automatic sync field detection and checksum generation. No external transceiver is needed for basic LIN slave functionality, reducing BOM cost in automotive body electronics.
What are the data flash endurance and voltage requirements for the R5F100GEGFB#V0?
The R5F100GEGFB#V0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports reprogramming at VDD = 1.8 V to 5.5 V. Background operation allows CPU code execution from main flash while data flash is being rewritten - essential for seamless firmware updates and runtime parameter storage in industrial controllers.
How does the R5F100GEGFB#V0 achieve ultra-low power consumption in STOP mode?
The R5F100GEGFB#V0 achieves 0.57 μA in STOP mode by powering down the CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and SRAM retention. Wake-up sources include RTC alarm, external interrupts, and LVD events - enabling precise, event-driven operation in battery-powered sensors and meters without compromising timing accuracy.
Is the R5F100GEGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GEGFB#V0 is pin-compatible with all 48-pin LFQFP RL78/G13 devices (e.g., R5F100GFGFB#V0, R5F101GEGFB#V0), sharing identical pin functions and electrical characteristics. This allows direct substitution within the same footprint for memory scaling or feature trade-offs - provided software accounts for differences in data flash presence or peripheral enablement.
