FAQ
What is the maximum operating frequency and corresponding performance of the R5F104JCAFA#V0?
The R5F104JCAFA#V0 operates up to 32 MHz with an RL78 CPU core delivering 44 DMIPS. Its minimum instruction execution time is 0.03125 μs in high-speed mode (32 MHz with on-chip oscillator), enabling deterministic real-time response for motor control and sensor fusion tasks. The R5F104JCAFA#V0 maintains this performance across its full 1.6–5.5 V supply range.
Does the R5F104JCAFA#V0 support hardware-based LIN communication?
Yes, the R5F104JCAFA#V0 supports LIN 2.2 physical layer implementation through UART2, including automatic sync-break detection, checksum calculation, and configurable baud rates. This hardware LIN capability reduces CPU loading by >70% compared to bit-banged implementations and ensures timing compliance in automotive body electronics and industrial fieldbus nodes using the R5F104JCAFA#V0.
How much data flash is integrated into the R5F104JCAFA#V0, and what is its endurance?
The R5F104JCAFA#V0 integrates 8 KB of data flash memory rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash-essential for reliable firmware parameter storage and event logging in deployed R5F104JCAFA#V0 systems.
What low-power modes are available on the R5F104JCAFA#V0, and what is the lowest current draw?
The R5F104JCAFA#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.60 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long operation on coin-cell batteries in wireless sensor nodes built around the R5F104JCAFA#V0.
Is the R5F104JCAFA#V0 pin-compatible with other RL78/G14 variants in the same 52-pin LQFP package?
Yes, all RL78/G14 52-pin LQFP variants-including R5F104JCAFA#V0, R5F104JGAFA#V0, and R5F104JHAFA#V0-share identical pinouts and electrical characteristics. This allows direct substitution within the same PCB layout when adjusting flash/RAM capacity, simplifying design reuse and inventory management for systems based on the R5F104JCAFA#V0.
