FAQ

What is the maximum operating frequency of the M30280F6HP#U3B?

The M30280F6HP#U3B supports a maximum CPU clock frequency of 20 MHz. This is achieved using the on-chip PLL with an external main crystal (1–20 MHz) or via direct main clock input. The peripheral clock (f₁, f₂, f₈, etc.) is derived from the same source and configurable through clock divider registers. All timing specifications in the hardware manual assume operation within this 20 MHz limit.

Does the M30280F6HP#U3B support in-circuit debugging?

Yes, the M30280F6HP#U3B includes an on-chip debug module compatible with Renesas E8/E8a emulators. It supports real-time program execution control, four hardware breakpoints, memory/register read/write, and trace via CLKOUT and dedicated debug pins. Debug access requires no additional firmware overhead and remains functional across all low-power modes except STOP mode.

What are the supported low-power modes for the M30280F6HP#U3B?

The M30280F6HP#U3B supports WAIT mode (CPU halted, peripherals and interrupts active) and STOP mode (all clocks stopped except sub-oscillator). In STOP mode, current consumption drops to ≤10 µA at 3.3 V and 25°C. Wake-up sources include external interrupt pins, RTC alarm, and LVD interrupt - all configurable before entering STOP mode.

Is the M30280F6HP#U3B pin-compatible with other M16C/28 Group devices?

Yes, the M30280F6HP#U3B is fully pin-compatible with other 100-pin LQFP variants in the M16C/28 and M16C/28B Groups, including M30282F8HP#U3B and R5F21285SNFP#30. Pin assignments for power, reset, clocks, and peripheral I/O match exactly - enabling drop-in replacement where memory and feature requirements align.

What is the ADC resolution and channel count of the M30280F6HP#U3B?

The M30280F6HP#U3B integrates a 10-bit successive-approximation ADC with 16 input channels (AN0–AN15). Conversion time is 1.7 µs per channel when f_AD = 10 MHz. Input channels are multiplexed across port P1 and P2 pins and selected via the ADAN register; the ADC supports software/start-triggered conversions and automatic channel sequencing.
