FAQ

What is the maximum operating frequency of the M30280F8HP#U5B?

The M30280F8HP#U5B supports a maximum CPU clock frequency of 48 MHz, achieved using its on-chip PLL with a 4–10 MHz crystal input and programmable multiplication factor (×4 to ×12). This allows precise timing control for high-resolution PWM and fast ADC sampling without external clock generators - critical for real-time motor control execution in the M30280F8HP#U5B.

Does the M30280F8HP#U5B include an integrated analog-to-digital converter?

Yes, the M30280F8HP#U5B integrates a 12-bit successive-approximation ADC with 8 input channels (AD0–AD7), programmable sampling time, and internal reference voltage. It supports single-shot and continuous conversion modes, with conversion complete interrupt and DMA trigger capability - enabling accurate sensor interfacing without external ADC components in the M30280F8HP#U5B.

Is the M30280F8HP#U5B compatible with IEBus communication?

Yes, the M30280F8HP#U5B includes a dedicated IEBus controller compliant with IEC 61158-2, supporting both master and slave operation, automatic CRC generation/check, and collision detection. This enables seamless integration into legacy Japanese building automation and industrial control networks - a defining feature distinguishing the M30280F8HP#U5B from generic 16-bit MCUs.

What low-power modes does the M30280F8HP#U5B support?

The M30280F8HP#U5B supports WAIT mode (CPU halted, peripherals active) and STOP mode (all clocks stopped, RAM retained). Wake-up from STOP mode occurs in ≤10 µs via external interrupt or reset, and voltage detection interrupts can trigger wake-up - making the M30280F8HP#U5B suitable for battery-backed sensor nodes and energy-efficient appliance standby functions.

What is the flash memory endurance specification for the M30280F8HP#U5B?

The M30280F8HP#U5B specifies 10,000 write/erase cycles for its 128 KB on-chip flash memory, with typical byte programming time of 100 µs. This endurance rating ensures reliable field firmware updates and parameter storage over extended product lifecycles - a validated specification confirmed in Renesas' M16C/28 Group Hardware Manual Rev.2.00 (2007) for the M30280F8HP#U5B.
