FAQ
What is the maximum operating frequency of the R5F64189HDFB#UA?
The R5F64189HDFB#UA operates at a maximum CPU frequency of 64 MHz, achieved via its on-chip PLL clock generator with main crystal input. This high-speed capability enables real-time execution of complex audio decoding and motor control algorithms without external co-processors. The 15.625 ns minimum instruction execution time is confirmed in the R01DS0065EJ0120 datasheet Section 1.1.2.
Does the R5F64189HDFB#UA support CAN FD or only classical CAN 2.0B?
The R5F64189HDFB#UA supports only classical CAN 2.0B (ISO 11898-1), not CAN FD. Its dual CAN modules provide 32 total mailboxes, programmable bit timing, and loopback self-test - fully compliant with legacy automotive and industrial CAN networks. CAN FD capability is absent per the R32C/118 Group datasheet Tables 1.1–1.4 and Section 1.1.2.
How many analog input channels does the R5F64189HDFB#UA have, and what is their resolution?
The R5F64189HDFB#UA features 26 analog input channels with 10-bit resolution and integrated sample-and-hold circuitry. This count applies specifically to the 100-pin package variant (PLQP0100KB-A), as documented in Table 1.4 and Figure 1.4 of the R01DS0065EJ0120 datasheet. Channels include P10_0–P10_7, P0_0–P0_7, and additional ANx inputs mapped to port pins.
Is the R5F64189HDFB#UA pin-compatible with other R32C/118 Group members in the same package?
Yes, the R5F64189HDFB#UA is pin-compatible with all other R32C/118 Group devices in the 100-pin LQFP (PLQP0100KB-A) package, including R5F64185HDFB#UA through R5F64188HDFB#UA. Pin assignments, peripheral mappings, and electrical characteristics are identical across the family - enabling hardware reuse when scaling flash/RAM requirements.
What debug interface does the R5F64189HDFB#UA support, and is on-chip flash programming available?
The R5F64189HDFB#UA supports JTAG-based on-chip debugging and on-board flash programming via its integrated debug module. This allows full breakpoint control, register inspection, and in-system flash erase/program without external hardware programmers - as specified in Section 1.1.2 "Debugging" of the R01DS0065EJ0120 datasheet and confirmed in the device's block diagram (Figure 1.2).
