FAQ
What is the maximum operating frequency of the R5F100JJAFA#V0?
The R5F100JJAFA#V0 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C). Instruction execution time ranges from 0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz, enabling dynamic clock scaling for power optimization. The R5F100JJAFA#V0 maintains full peripheral functionality across this range without external crystal dependency.
Does the R5F100JJAFA#V0 include an integrated temperature sensor?
Yes, the R5F100JJAFA#V0 integrates a calibrated temperature sensor usable via the 10-bit ADC (channel ANI25). It operates across the full -40°C to +85°C ambient range and is accessible when the HS (high-speed main) mode is selected. This sensor eliminates external components in thermal monitoring applications such as battery pack management or motor temperature feedback within the R5F100JJAFA#V0-based design.
What packaging and lead finish does the R5F100JJAFA#V0 use?
The R5F100JJAFA#V0 is supplied in a 52-pin LQFP package (10 mm × 10 mm, 0.65 mm pitch) with lead finish specified as matte tin (Sn) per JEDEC J-STD-609. The ordering code #V0 indicates tray packaging (PLQP0052JA-A / PLQP0052JD-B), compliant with RoHS and REACH requirements. No lead-free exemption applies - the R5F100JJAFA#V0 is fully lead-free and halogen-free.
Can the R5F100JJAFA#V0 execute code while rewriting data flash memory?
Yes, the R5F100JJAFA#V0 supports Background Operation (BGO) for data flash memory, allowing program execution from code flash while simultaneously rewriting data flash. This enables seamless firmware updates and parameter storage without halting real-time tasks. The R5F100JJAFA#V0 guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V, with dedicated RAM areas (starting at FAF00H) reserved for flash library operations.
Which communication interfaces are available on the R5F100JJAFA#V0?
The R5F100JJAFA#V0 provides UART/LIN (4 channels), I²C/Simplified I²C (up to 10 channels), and CSI/SPI (8 channels) - all configurable on shared pins with programmable pull-up/pull-down and open-drain options. These interfaces support mixed-voltage operation (1.8 V/2.5 V/3.0 V I/O), enabling direct connection to diverse peripherals without level shifters. All protocols are hardware-accelerated and operate independently under DMA control in the R5F100JJAFA#V0.
