FAQ

What is the maximum operating frequency and voltage range for the M30873FHGP#U3?

The M30873FHGP#U3 operates at up to 24 MHz with a supply voltage range of VCC1 = 3.0 V to 5.5 V and VCC2 = 3.0 V to VCC1. At 32 MHz operation, VCC1 must be 4.2–5.5 V - but M30873FHGP#U3 is rated only for 24 MHz per its flash configuration and temperature grade. This ensures reliable execution of motor control code under industrial ambient conditions.

Does the M30873FHGP#U3 support CAN FD or only classical CAN 2.0B?

The M30873FHGP#U3 supports only CAN 2.0B (ISO 11898-1:1993), not CAN FD. Its CAN module implements 16 mailboxes with identifier masking and acceptance filtering, compliant with the classical 11-/29-bit identifier and 0–8 byte payload specification. M30873FHGP#U3 does not include bit-rate switching or extended data length features required for CAN FD.

How many ADC channels are accessible in single-chip mode on the M30873FHGP#U3?

In single-chip mode, the M30873FHGP#U3 provides 26 channels of 10-bit ADC input. This count is confirmed in Table 1.4 for the 100-pin package variant and includes sample-and-hold functionality. The number drops to 10 channels in memory expansion or microprocessor modes due to pin multiplexing with external bus signals.

Is the M30873FHGP#U3 pin-compatible with other M32C/87A variants in the same package?

Yes, the M30873FHGP#U3 shares identical pinout and electrical characteristics with all M32C/87A variants in the PLQP0100KB-A (100-pin LQFP) package, including M30879FLAGP and M30876FJAGP. Pin assignments, power domains, and peripheral mappings are consistent across the M32C/87A family - enabling drop-in replacement within the same ROM/RAM capacity tier.

What debug interfaces does the M30873FHGP#U3 support for firmware development?

The M30873FHGP#U3 supports on-chip debug via the dedicated debug port (pins P1_0–P1_3) compliant with Renesas E8/E8a debug protocol. It enables full breakpoint control, register inspection, and flash programming without external JTAG adapters. This debug capability is built into the silicon and active in all M30873FHGP#U3 units regardless of ROM configuration.
