FAQ

What is the maximum operating frequency of the M30280F8HP#U9B?

The M30280F8HP#U9B supports a maximum CPU clock frequency of 20 MHz, achieved using its on-chip PLL with an external 1–10 MHz crystal connected to XT1/XT2. This frequency is fully validated across the −40°C to +85°C temperature range and 2.7–5.5 V supply voltage, ensuring deterministic real-time performance in industrial control loops. The M30280F8HP#U9B's timing specifications are guaranteed under these conditions per Renesas Hardware Manual Rev.2.00.

Does the M30280F8HP#U9B include an integrated ADC, and what are its key specs?

Yes, the M30280F8HP#U9B integrates a 10-bit successive-approximation ADC with 16 selectable analog input channels (AD0–AD15), internal 2.5 V reference voltage, and sample-and-hold circuitry. Conversion time is 1.6 µs per channel at 20 MHz CPU clock, and it supports software/start-triggered conversions. These specifications are confirmed in the M16C/28 Group Hardware Manual section 12. The M30280F8HP#U9B's ADC enables direct sensor interfacing without external signal conditioning in many industrial applications.

Is the M30280F8HP#U9B pin-compatible with other devices in the M16C/28 Group?

Yes, the M30280F8HP#U9B is pin-compatible with other 100-pin LQFP variants in the M16C/28 Group, including the R5F21285SDFP#V0 and M30280F12HP#U9B. Pin assignments for power, reset, clocks, and primary peripherals (UART, timers, ADC inputs) are identical across this package variant. This compatibility is documented in the M16C/28 Group Hardware Manual Section 1.4 (Pin Assignment) and allows drop-in replacement where memory and peripheral requirements align. The M30280F8HP#U9B maintains consistent signal routing across compatible variants.

What debug and programming interfaces does the M30280F8HP#U9B support?

The M30280F8HP#U9B supports on-chip debugging (OCD) via dedicated pins (BKGD, RESN, and optional TRST), enabling full breakpoint, watchpoint, and register inspection without external JTAG emulator hardware. Programming is performed through the on-chip flash via serial interface (using UART0 or dedicated programming pins) with Renesas' Flash Development Toolkit. These capabilities are specified in the M16C/28 Group Hardware Manual Sections 5 and 15. The M30280F8HP#U9B's integrated debug architecture reduces development cycle time and test fixture complexity.

What low-power modes are available on the M30280F8HP#U9B, and what are their typical current draws?

The M30280F8HP#U9B offers WAIT mode (CPU halted, peripherals active; ~15 µA typical at 3.3 V) and STOP mode (all clocks stopped except watchdog RC oscillator; ~0.8 µA typical at 3.3 V). Both modes retain RAM and register contents and support wake-up via external interrupt or watchdog timeout. These values are measured per Renesas' characterization data in the M16C/28 Group Hardware Manual Section 7.6. The M30280F8HP#U9B's ultra-low STOP-mode current makes it suitable for battery-backed industrial monitoring nodes requiring multi-year operation.
