FAQ
What is the maximum operating frequency and voltage range supported by the R5F140PLAFB#30?
The R5F140PLAFB#30 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, with guaranteed operation across 1.6–5.5 V supply voltage. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports external crystal oscillators up to 20 MHz for main system clock and 32.768 kHz for subsystem timing - all within the specified voltage and temperature range.
Does the R5F140PLAFB#30 include hardware security features for firmware protection?
Yes, the R5F140PLAFB#30 includes multiple hardware security features: flash memory block erase/write prohibition, flash shield window function to restrict access to protected code regions, and on-chip debug lock to prevent unauthorized readout. These features are implemented in silicon and do not require external components - enabling secure boot, IP protection, and anti-cloning in production firmware deployments.
How many UART channels with LIN-bus support does the R5F140PLAFB#30 provide?
The R5F140PLAFB#30 provides four UART channels, with UART0, UART1, UART2, and UART3 all supporting LIN-bus protocol. Each channel includes dedicated LINSEL pin control and automatic baud rate detection - allowing simultaneous operation of multiple LIN nodes in automotive body electronics or industrial sensor networks without external transceivers.
What is the purpose of the EVDD0, EVDD1, EVSS0, and EVSS1 pins on the R5F140PLAFB#30?
The EVDD0/EVDD1 and EVSS0/EVSS1 pins on the R5F140PLAFB#30 provide separate power and ground domains for analog and high-noise digital peripherals. EVDD0 powers port 0–7 analog circuitry; EVDD1 powers port 8–15 and serial interfaces. Separating these domains minimizes switching noise coupling into ADC and RTC circuits - improving measurement accuracy and timing stability in mixed-signal applications.
Can the R5F140PLAFB#30 perform background data flash rewriting while executing application code from code flash?
Yes, the R5F140PLAFB#30 supports background operation (BGO) for data flash rewriting. While the CPU executes instructions from code flash memory, the flash control unit independently handles data flash erase and write operations - enabling continuous real-time operation during firmware updates, event logging, or parameter storage without interrupting system functionality.
