FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LDGFB#30?
The R5F104LDGFB#30 operates up to 32 MHz with a typical active current of 66 μA/MHz. At full speed, this yields ~2.1 mA total active current (VDD = 3.3 V, TA = 25°C). Its ultra-low-power STOP mode draws just 0.60 μA with RTC and LVD enabled - critical for long-life battery applications. These values are measured per R01DS0053EJ0370 Rev. 3.70.
Does the R5F104LDGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104LDGFB#30 supports full in-system programming via its on-chip debug interface (TOOL0 pin) and includes flash shield window protection, block erase prohibition, and boot swapping functionality. These features enable secure field firmware updates with rollback capability - essential for industrial deployments requiring integrity and recoverability.
How many UART/LIN channels does the R5F104LDGFB#30 provide, and are they LIN 2.2 compliant?
The R5F104LDGFB#30 provides four UART channels, all supporting LIN 2.2 protocol via built-in LIN break detection, sync field handling, and checksum calculation. This allows simultaneous communication with multiple LIN slave nodes - such as motor drivers or sensor modules - without external transceivers or software overhead.
What is the purpose of the REGC pin on the R5F104LDGFB#30, and what capacitor value is required?
The REGC pin on the R5F104LDGFB#30 connects to the internal voltage regulator's bypass capacitor. A 0.47 µF to 1.0 µF ceramic capacitor must be placed between REGC and VSS to stabilize the regulator and ensure reliable operation across temperature and load conditions - as specified in R01DS0053EJ0370 Section 1.3.6.
Can the R5F104LDGFB#30 perform ADC conversions while executing code from flash memory?
Yes, the R5F104LDGFB#30 supports concurrent ADC operation and CPU execution. Its 10-bit ADC can sample up to 20 channels with programmable trigger sources (including timer overflows and external pins), and conversion results are stored directly to RAM without CPU intervention - enabling deterministic real-time acquisition in motor control or sensor fusion applications.
