FAQ
What is the maximum operating frequency of the R5F64168PFD#UC?
The R5F64168PFD#UC operates at a maximum CPU frequency of 64 MHz, achieved via its on-chip PLL frequency synthesizer driven by an external crystal (e.g., 8 MHz) or ceramic resonator. This speed is sustained across its full −40°C to +85°C operating temperature range and 3.0–5.5 V supply voltage.
Does the R5F64168PFD#UC support in-system programming via UART?
Yes, the R5F64168PFD#UC supports on-board flash programming through UART channels (e.g., UART0), enabled by its integrated on-chip debug module. This allows firmware updates in the field without requiring dedicated debug headers or external programmers - a key feature confirmed in Section 1.1.2 of the R01DS0063EJ0120 datasheet.
How many analog-to-digital converter channels does the R5F64168PFD#UC provide?
The R5F64168PFD#UC integrates a 10-bit successive-approximation ADC with up to 34 input channels, as specified for the 144-pin package in Table 1.1. These include primary analog inputs (AN_0–AN_7), extended analog inputs (AN0_0–AN0_7, AN2_0–AN2_7, AN15_0–AN15_7), and auxiliary channels (ANEX0/ANEX1), all supported by sample-and-hold circuitry.
Is the R5F64168PFD#UC pin-compatible with other R32C/116 Group devices?
Yes, all 144-pin R32C/116 Group variants - including R5F64165NFD#UC, R5F64166DFD#UC, and R5F64169PFD#UC - share identical pin assignments and electrical characteristics per Figure 1.3 and Tables 1.7–1.10. This enables hardware reuse across memory and temperature grade variants without PCB redesign.
What debug interface does the R5F64168PFD#UC use?
The R5F64168PFD#UC uses Renesas' proprietary on-chip debug (OCD) interface, accessible via dedicated debug pins (not multiplexed with general-purpose I/O) and supported by E2 studio and CS+ IDEs. It provides full breakpoint, watchpoint, and real-time trace capabilities without consuming UART or SWD resources.
