FAQ
What is the operating voltage range supported by the R5F104LCAFP#30?
The R5F104LCAFP#30 operates from 1.6 V to 5.5 V, enabling direct interface with 1.8 V, 3.3 V, and 5 V systems without level shifters. Its on-chip voltage detector (LVD) offers 14 programmable threshold levels for brown-out detection and reset control across this full range.
Does the R5F104LCAFP#30 support background data flash rewriting (BGO)?
Yes, the R5F104LCAFP#30 supports background data flash rewriting (BGO), allowing CPU code execution from program memory while simultaneously erasing or programming the 8 KB data flash. This enables seamless firmware updates and nonvolatile parameter storage without interrupting real-time operation.
What is the maximum number of analog input channels on the R5F104LCAFP#30?
The R5F104LCAFP#30 features a 10-bit A/D converter with up to 20 analog input channels (ANI0–ANI19), including dedicated inputs for internal temperature sensor and voltage references (AVREFP/AVREFM), supporting simultaneous multi-sensor acquisition in industrial monitoring applications.
Which package type and pin count does the R5F104LCAFP#30 use?
The R5F104LCAFP#30 uses a 64-pin LQFP package with 0.65 mm pitch (RENESAS code PLQP0064JA-A), measuring 12 × 12 mm. It is distinct from LFQFP (0.5 mm pitch) and FLGA variants - this specific footprint ensures mechanical and thermal compatibility with standard industrial PCB assembly processes.
What industrial temperature grade is specified for the R5F104LCAFP#30?
The R5F104LCAFP#30 is rated for industrial operation from -40°C to +85°C (D-grade), validated per Renesas' industrial qualification standards. It is not rated for extended temperature (G-grade: -40°C to +105°C), making it suitable for enclosed control cabinets and factory-floor environments with active thermal management.
How many UART/LIN channels does the R5F104LCAFP#30 integrate?
The R5F104LCAFP#30 integrates four UART channels, all supporting LIN-bus protocol (LIN 2.2A compliant). Each channel includes independent baud rate generators, break detection, and automatic sync byte handling - enabling concurrent communication with motor drivers, sensors, and diagnostic tools in distributed control systems.
