FAQ
What is the maximum operating frequency of the R5F64165PFD#UC?
The R5F64165PFD#UC is a normal-speed variant rated for 50 MHz operation, delivering a minimum instruction execution time of 15.625 ns. It does not support the 64 MHz high-speed mode found in R5F64165HNFD#UC and related parts. This frequency is validated across the full −40°C to +85°C temperature range with VCC = 3.0–5.5 V.
Does the R5F64165PFD#UC include an on-chip debug interface?
Yes, the R5F64165PFD#UC integrates a full on-chip debug module compliant with Renesas' standard debug protocol, supporting breakpoints, watchpoints, register inspection, and flash programming during development and field updates. Debug access uses dedicated pins (RESET, XIN/XOUT, XCIN/XCOUT) and requires no external JTAG adapter beyond standard Renesas E2 or E2 Lite debuggers.
How many analog input channels does the R5F64165PFD#UC support?
The R5F64165PFD#UC supports 34 channels of 10-bit A/D conversion, distributed across AN_0–AN_7 (P10_0–P10_7), AN0_0–AN0_7 (P0_0–P0_7), AN2_0–AN2_7 (P2_0–P2_7), and AN15_0–AN15_7 (P15_0–P15_7). All channels include integrated sample-and-hold circuitry, enabling simultaneous sampling of up to four inputs in burst mode.
Is the R5F64165PFD#UC pin-compatible with other R32C/116 Group devices?
Yes, all 144-pin R32C/116 Group MCUs-including R5F64165PFD#UC, R5F64166PFD#UC, and R5F64167PFD#UC-share identical PLQP0144KA-A package pinouts and peripheral signal assignments. Memory size, RAM capacity, and certain optional features (e.g., IEBus) differ, but PCB layout and firmware initialization sequences remain compatible across the group.
What serial communication interfaces are available on the R5F64165PFD#UC?
The R5F64165PFD#UC provides nine independent UART channels (UART0–UART8), with UART0–UART6 configurable as I²C-bus interfaces. It also supports special mode 2 (synchronous serial) and optional IEBus (requires sales office consultation). No native CAN, LIN, or USB interfaces are integrated - these require external transceivers or bridge ICs.
