It operates at up to 20 MHz CPU clock with 3.3 V supply and targets industrial control and embedded instrumentation applications.

For engineers reviewing the M30280FAHP#U7B datasheet, M30280FAHP#U7B pinout, M30280FAHP#U7B application, or M30280FAHP#U7B equivalent, key selection considerations include its 100-pin LQFP package, dual clock system (main/sub), on-chip voltage detector, watchdog timer, and support for WAIT/STOP low-power modes - all critical for deterministic real-time control in resource-constrained systems.

Technical Context

The M30280FAHP#U7B implements the M16C CPU core with 16-bit data bus and 24-bit address space, supporting both CISC instruction set and bit manipulation instructions. It integrates a PLL-based clock generation circuit enabling flexible CPU/peripheral clock division (f1, f2, f8, f32, fAD), and includes a dedicated on-chip voltage detection circuit with programmable threshold and interrupt capability.

Its peripheral suite includes three 16-bit timer/counters with input capture/output compare, two UART channels with framing error detection, one I²C-compatible serial interface, and a 10-bit, 16-channel successive-approximation ADC with scan mode and conversion completion interrupt - all accessible via memory-mapped SFRs and configurable through dedicated control registers.

FAQ

What is the maximum operating frequency of the M30280FAHP#U7B?

The M30280FAHP#U7B supports a maximum CPU clock frequency of 20 MHz, achieved using its on-chip PLL to multiply an external main clock input (1–10 MHz). This frequency is sustained across the full −40°C to +85°C industrial temperature range and 3.0–3.6 V supply voltage, enabling deterministic execution of real-time control tasks without timing margin degradation.

Does the M30280FAHP#U7B include on-chip debug support?

Yes, the M30280FAHP#U7B integrates on-chip debugging circuitry compatible with Renesas E8/E8a emulators via the dedicated BKGD pin. It supports full breakpoint, watchpoint, and single-step execution capabilities without requiring external JTAG hardware, simplifying firmware development and field diagnostics for the M30280FAHP#U7B.

What low-power modes does the M30280FAHP#U7B support?

The M30280FAHP#U7B supports WAIT mode (CPU halted, peripherals active) and STOP mode (all clocks halted except optional sub-clock). In STOP mode with sub-clock enabled, typical current consumption is less than 1 μA, making it suitable for battery-backed applications where periodic wake-up via external interrupt or sub-clock timer is required - a key capability of the M30280FAHP#U7B.

Is the M30280FAHP#U7B pin-compatible with other M16C/28 devices?

Yes, the M30280FAHP#U7B uses the standard 100-pin LQFP package and shares identical pin assignments with other members of the M16C/28 Group (e.g., M30280FAXP#U7B, M30280FAGP#U7B), enabling drop-in replacement within the same family for memory size or feature-level upgrades without PCB redesign - a verified compatibility for the M30280FAHP#U7B.

What is the ADC resolution and channel count of the M30280FAHP#U7B?

The M30280FAHP#U7B features a 10-bit successive-approximation ADC with 16 input channels (AD0–AD15), supporting simultaneous sampling control, automatic channel scanning, and conversion completion interrupts. Its 1.2 μs conversion time and dedicated analog power pins (EXVCC/EXVSS) ensure consistent accuracy across industrial temperature ranges - a defining specification of the M30280FAHP#U7B.
