It integrates dual UARTs, I²C, 10-bit 24-channel ADC, three-phase motor control timer (TimerS), and DMAC - deployed in inverter-driven home appliances and industrial motor control systems.

For engineers reviewing the M30280FCBHP#U7B datasheet, M30280FCBHP#U7B pinout, M30280FCBHP#U7B application, or M30280FCBHP#U7B equivalent, key selection criteria include its 80-pin LQFP footprint, 24 MHz BCLK capability with PLL, 128KB Flash endurance (10,000 cycles in Blocks A/B), -20°C to +85°C operating range, and integrated three-phase PWM generation for brushless DC motor drives.

Technical Context

The M30280FCBHP#U7B implements the M16C/60 CPU core with 91 instructions and executes minimum instructions in 41.7 ns at 24 MHz (VCC = 4.2–5.5 V). It operates exclusively in single-chip mode with a 1-Mbyte address space and supports four clock sources: main crystal (XIN/XOUT), sub-crystal (XCIN/XCOUT), on-chip oscillator, and PLL frequency synthesizer - the latter required for 24 MHz operation.

Peripheral integration includes TimerA (16-bit × 5), TimerB (16-bit × 3), TimerS (16-bit base with 8-channel input capture/output compare for three-phase motor control), two UARTs with clock-synchronous SI/O support, and a multi-master I²C bus interface. The device also features an oscillation stop detection circuit and voltage detection circuit for system-level reliability.

FAQ

What is the maximum operating frequency and required supply voltage for M30280FCBHP#U7B?

The M30280FCBHP#U7B achieves a maximum BCLK frequency of 24 MHz when powered at VCC = 4.2 V to 5.5 V. This requires activation of the on-chip PLL frequency synthesizer. At lower supply voltages (3.0–5.5 V), the device operates up to 20 MHz; at 2.7–5.5 V, up to 10 MHz. The M30280FCBHP#U7B datasheet specifies these voltage-frequency dependencies explicitly in Table 1.1.

Does M30280FCBHP#U7B support three-phase motor control natively?

Yes, the M30280FCBHP#U7B includes TimerS - a dedicated 16-bit three-phase motor control timer with eight input capture/output compare channels. It supports waveform generation (e.g., complementary PWM with dead-time insertion) and time measurement (e.g., Hall sensor edge detection) essential for BLDC and PMSM commutation. This hardware block is documented in the M30280FCBHP#U7B hardware manual Section 1.2.

What is the Flash memory endurance specification for M30280FCBHP#U7B?

The M30280FCBHP#U7B Flash memory provides 10,000 program/erase cycles specifically for Blocks A and B, while other blocks guarantee 1,000 cycles. This tiered endurance enables robust firmware update strategies - critical sections (e.g., bootloader, calibration tables) can be placed in high-endurance blocks. Full details appear in Table 1.5 of the M30280FCBHP#U7B product documentation.

Which package type does M30280FCBHP#U7B use, and what are its mechanical dimensions?

The M30280FCBHP#U7B uses the 80-pin plastic mold LQFP package designated PLQP0080KB-A (also referenced as 80P6Q-A), measuring 12 mm × 12 mm with 0.5 mm lead pitch. Pin assignments and mechanical drawings are provided in Figures 1.5 and 1.6 of the M30280FCBHP#U7B hardware manual, confirming compatibility with standard 80-pin LQFP footprints.

What communication interfaces are available on M30280FCBHP#U7B?

The M30280FCBHP#U7B integrates UART0 and UART1 (asynchronous/clock-synchronous), UART2 (configurable as UART, I²C, or IEBus), SI/O3 and SI/O4 (clock-synchronous serial), and a dedicated multi-master I²C bus. These interfaces support mixed-protocol connectivity - for example, UART0 for host debugging, I²C for sensor networks, and SI/O4 for isolated actuator control - all documented in the M30280FCBHP#U7B peripheral function table.
