FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R5F21354CDFP#V2?
The R5F21354CDFP#V2 operates at up to 20 MHz when supplied with VCC = 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At reduced clock speeds (e.g., 5 MHz), it supports extended voltage range down to 1.8 V, enabling compatibility with single-cell Li-ion or alkaline battery systems where low-voltage operation is essential.
Does the R5F21354CDFP#V2 support hardware LIN communication, and how is it implemented?
Yes, the R5F21354CDFP#V2 includes a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards. It is implemented by combining Timer RA for baud rate generation and signal edge timing with UART0 for data framing and error checking - eliminating software bit-banging and ensuring robust bus arbitration and slave node response timing.
How does the Background Operation (BGO) function work in the R5F21354CDFP#V2 data flash?
The R5F21354CDFP#V2 supports Background Operation (BGO) for its 4 KB data flash (1 KB × 4 blocks), allowing CPU code execution to continue uninterrupted while flash erase or write operations occur. This is enabled via dedicated SFRs (FMRDYIC, FRAx registers) and requires no external memory mapping - critical for maintaining real-time responsiveness during firmware parameter updates.
What are the low-power consumption figures for the R5F21354CDFP#V2 in wait and stop modes?
In wait mode with XCIN = 32 kHz active, the R5F21354CDFP#V2 draws typ. 3.5 µA at VCC = 3.0 V; in stop mode (all clocks halted except optional 32 kHz watch crystal), it consumes typ. 2.0 µA at the same voltage. These values assume minimal peripheral activation and are measured per Renesas datasheet R01DS0006EJ0100 Rev 1.00.
Which pins on the R5F21354CDFP#V2 support analog functions, and what is their resolution?
The R5F21354CDFP#V2 supports analog input on 12 dedicated pins: AN0–AN11 (mapped across P0_0–P0_7, P1_0–P1_3), each with 10-bit resolution and sample-and-hold capability. Additionally, DA0 and DA1 (on P0_6 and P0_7) provide 8-bit analog voltage outputs - enabling simultaneous sensing and actuation within a single chip.
