FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100LGDFB#50?
The R5F100LGDFB#50 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. Its RL78 CPU core features a 3-stage pipeline and supports configurable instruction timing - from 0.03125 μs per instruction at full speed to 30.5 μs in ultra-low-speed subsystem mode - enabling precise trade-offs between throughput and power consumption in the R5F100LGDFB#50.
Does the R5F100LGDFB#50 support hardware-based LIN bus communication?
Yes, the R5F100LGDFB#50 supports LIN bus communication through its UART peripheral with built-in LIN protocol features, including automatic sync-break detection, checksum calculation, and baud rate adjustment. This eliminates the need for an external LIN transceiver in applications like automotive body control modules and industrial sensor networks using the R5F100LGDFB#50.
What are the flash memory configuration details for the R5F100LGDFB#50?
The R5F100LGDFB#50 integrates 128 KB of code flash memory organized in 1 KB blocks and 8 KB of data flash memory. It supports self-programming with boot swap functionality, flash shield window security, and background operation (BGO) - allowing code execution from program memory while rewriting data flash. The flash library reserves RAM starting at address F7F00H, as documented for R5F100xL devices in the R5F100LGDFB#50 datasheet.
How does the R5F100LGDFB#50 achieve ultra-low power consumption in STOP mode?
The R5F100LGDFB#50 achieves 0.57 μA STOP mode current by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits while shutting down the CPU, flash, RAM, and most peripherals. This mode supports wake-up via RTC alarm, LVD threshold violation, or external interrupt - making it ideal for infrequent-event sensing applications using the R5F100LGDFB#50 in battery-powered deployments.
Is the R5F100LGDFB#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LGDFB#50 is pin-compatible with all other RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCAFB#50, R5F100LLAFB#50), sharing identical pin functions, electrical characteristics, and footprint. Firmware portability across memory variants is supported within the RL78/G13 family, though users must verify peripheral enablement and memory map alignment for each specific R5F100LGDFB#50 configuration.
