FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MJGFB#30?
The R5F100MJGFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. Its RL78 CPU core achieves this through a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over 1.8–5.5 V and -20 to +85°C). The minimum instruction execution time is 0.03125 μs in high-speed mode, enabling deterministic real-time response for motor control and sensor processing tasks.
Does the R5F100MJGFB#30 support hardware LIN communication, and how is it implemented?
Yes, the R5F100MJGFB#30 supports hardware LIN communication via UART0 and UART1 peripherals. Each UART includes dedicated LIN-mode registers for automatic break detection, sync field generation, and checksum calculation per LIN 2.2A specification. This eliminates software overhead and ensures reliable frame timing-critical for automotive body electronics and industrial sub-bus networks.
What are the data flash endurance and rewrite voltage requirements for the R5F100MJGFB#30?
The R5F100MJGFB#30 features 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) with background operation (BGO) enabled. Rewrites are supported across the full supply range of 1.8 V to 5.5 V, allowing safe in-field updates without external voltage regulation. The flash library reserves specific RAM regions (e.g., FAF00H for R5F100xJ variants) for self-programming operations.
How does the R5F100MJGFB#30 achieve ultra-low power consumption in STOP mode?
The R5F100MJGFB#30 achieves 0.57 μA STOP mode current by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits while powering down the CPU, flash, RAM, and most peripherals. Wake-up sources include RTC alarm, LVD threshold crossing, and external interrupts on designated pins-ensuring rapid resumption (<;1.5 μs) without compromising energy efficiency in battery-critical applications.
Is the R5F100MJGFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100MJGFB#30 is pin-compatible with all other RL78/G13 MCUs in the 80-pin LFQFP-0.5mm package (e.g., R5F100MLGFB#30, R5F101MJGFB#30), sharing identical pin functions, electrical characteristics, and thermal behavior. This enables seamless migration across memory configurations and feature sets without PCB redesign-provided the target variant's peripheral mapping matches the application's runtime requirements.
