FAQ
What is the maximum operating frequency and voltage range for the R5F64169DFB#UB?
The R5F64169DFB#UB operates at up to 64 MHz with a supply voltage range of 3.0 V to 5.5 V. Its minimum instruction execution time is 15.625 ns at full speed, and it maintains functionality across the full industrial temperature range of –40°C to +85°C. This voltage flexibility allows direct interfacing with both legacy 5 V and modern 3.3 V subsystems without external level shifters.
Does the R5F64169DFB#UB support hardware debugging and in-system flash programming?
Yes, the R5F64169DFB#UB includes an on-chip debug module and supports on-board flash programming. Engineers can perform full-cycle development - including breakpoint setting, register inspection, and flash erase/write - using standard JTAG or dedicated debug interfaces without requiring external programmers. This capability streamlines firmware validation and field updates for the R5F64169DFB#UB.
How many analog-to-digital converter channels does the R5F64169DFB#UB provide, and what is their resolution?
The R5F64169DFB#UB integrates a 10-bit successive-approximation ADC with 26 input channels. All channels feature built-in sample-and-hold circuitry, enabling accurate simultaneous sampling of multiple analog signals such as motor phase currents or temperature sensors. This ADC configuration is confirmed for the 100-pin package variant of the R5F64169DFB#UB.
What serial communication interfaces are available on the R5F64169DFB#UB?
The R5F64169DFB#UB provides nine asynchronous/synchronous serial interface channels (UART0–UART8), one multi-master I²C-bus interface, and optional IEBus support. UART channels support hardware flow control (CTS/RTS), clock synchronization, and special modes for protocol adaptation - making the R5F64169DFB#UB suitable for multi-peripheral communication in complex embedded systems.
Is the R5F64169DFB#UB pin-compatible with other members of the R32C/116 Group?
The R5F64169DFB#UB shares identical pinout and electrical characteristics with other 100-pin R32C/116 Group variants (e.g., R5F64165DFB#UB, R5F64168DFB#UB), enabling drop-in replacement within the same package family. However, it is not pin-compatible with 144-pin variants like R5F64169DFD#UB due to differing pin counts and peripheral mappings.
