FAQ
What is the maximum operating frequency of the M30280FAHP#U3B?
The M30280FAHP#U3B supports a maximum CPU operating frequency of 20 MHz. This is achieved either directly from an external crystal oscillator (up to 20 MHz) or via the on-chip PLL circuit configured to multiply a lower-frequency input. The device's timing specifications-including ADC conversion time, PWM resolution, and UART baud rate accuracy-are guaranteed across this full frequency range under specified voltage and temperature conditions.
Does the M30280FAHP#U3B support IEBus communication?
Yes, the M30280FAHP#U3B includes a dedicated IEBus controller compliant with the NEC IEBus standard (IEBus Ver. 2.0). It supports master/slave operation, automatic frame formatting, CRC generation/checking, and collision detection-enabling robust inter-equipment communication in automotive HVAC systems and industrial control panels without external protocol ICs.
What low-power modes does the M30280FAHP#U3B offer?
The M30280FAHP#U3B provides two hardware-controlled low-power modes: WAIT mode (CPU halted, peripherals and interrupts active) and STOP mode (all clocks stopped except optional sub-oscillator). In STOP mode with sub-oscillator enabled, typical current consumption is less than 1 µA, making it suitable for battery-backed applications requiring infrequent wake-up events such as sensor polling or watchdog timeouts.
Is the M30280FAHP#U3B pin-compatible with other M16C/28 devices?
Yes, the M30280FAHP#U3B uses the same 100-pin LQFP package and shares identical pin assignments with other members of the M16C/28 Group, including M30281F8HP#U3B and M30282F8HP#U3B. This allows drop-in replacement within the same family for memory or peripheral scaling-provided software is updated to match the target device's flash/RAM map and SFR configuration.
What debug interface does the M30280FAHP#U3B support?
The M30280FAHP#U3B supports single-wire debug (SWD) via the dedicated BKGD pin, enabling full on-chip debugging-including breakpoints, register inspection, and memory read/write-without requiring JTAG headers or external emulators. This interface is fully supported by Renesas' E1/E20 debuggers and CS+ IDE, allowing rapid development and field firmware updates.
