FAQ
What is the maximum operating frequency of the R5F2L368CDFA#30?
The R5F2L368CDFA#30 supports a maximum external crystal frequency of 20 MHz at VCC = 2.7–5.5 V, enabling a minimum instruction execution time of 50 ns. Its internal high-speed on-chip oscillator is factory-trimmed and adjustable via software, providing flexible clocking without external components.
Does the R5F2L368CDFA#30 support in-application programming (IAP) of its flash memory?
Yes, the R5F2L368CDFA#30 supports in-application programming via its on-chip debug function and background operation (BGO) capability. This allows the R5F2L368CDFA#30 to execute user code while erasing or writing to data flash memory, enabling field firmware updates without system interruption.
How many LCD segment and common pins does the R5F2L368CDFA#30 provide?
The R5F2L368CDFA#30 provides up to 32 segment output pins and 8 common output pins, supporting static, 1/2, 1/3, 1/4, and 1/8 duty LCD configurations. This matches the R8C/L36C Group specification and is confirmed in Table 1.3 and Figure 1.10 of the R01DS0095EJ0101 datasheet.
Is the R5F2L368CDFA#30 pin-compatible with other R8C/L3x series MCUs?
No, the R5F2L368CDFA#30 is not pin-compatible with R8C/L35C, R8C/L38C, or R8C/L3AC Group devices. While all share the 64-pin LQFP package option, pin assignments differ significantly - especially for LCD, timer, and serial interface signals - as shown in Figures 1.9–1.13 of the datasheet.
What debug interface does the R5F2L368CDFA#30 support?
The R5F2L368CDFA#30 supports Renesas' on-chip debug interface using the single-wire FINE protocol. This requires only one dedicated debug pin (typically P12_0 or P12_1 depending on configuration) and enables full breakpoint, watchpoint, and memory inspection capabilities without JTAG overhead.
