For engineers reviewing the M30280F6HP#U7B datasheet, M30280F6HP#U7B pinout, M30280F6HP#U7B application, or M30280F6HP#U7B equivalent, key selection considerations include its 64-pin LQFP package, 10-bit ADC with 8-channel input, hardware multiplier, low-power STOP/WAIT modes, and compatibility with Renesas' M16C development tools and C compiler suite.

Technical Context

The M30280F6HP#U7B implements the M16C CPU core with 16-bit data bus and 24-bit address space, supporting both 16-bit and 32-bit arithmetic via dedicated hardware multiplier. Its clock system integrates main crystal oscillator (1–10 MHz), sub-oscillator (32.768 kHz), on-chip RC oscillator, and PLL for CPU clock generation up to 20 MHz.

Peripheral integration includes three 16-bit timer/counters (one with PWM output), two serial interfaces (UART and CSI), 10-bit successive-approximation ADC with sample-and-hold, and 64 I/O pins configurable as general-purpose or peripheral function pins. Reset management includes hardware reset, watchdog timer reset, oscillation stop detection, and low-voltage detection interrupt.

FAQ

What is the maximum operating frequency of the M30280F6HP#U7B?

The M30280F6HP#U7B supports a maximum CPU clock frequency of 20 MHz, achieved using the on-chip PLL with an external 1–10 MHz crystal connected to XIN/XOUT. This frequency is sustained across the full 2.7–5.5 V supply range and ambient temperature of –40°C to +85°C, enabling deterministic real-time execution for motor control and sensor processing tasks. The M30280F6HP#U7B also supports lower-frequency modes (e.g., sub-oscillator at 32.768 kHz) for ultra-low-power wake-up operations.

Does the M30280F6HP#U7B include an integrated ADC, and what are its specifications?

Yes, the M30280F6HP#U7B integrates a 10-bit successive-approximation ADC with 8 selectable analog input channels (AD0–AD7), programmable sample-and-hold time, and internal reference voltage. Conversion time is 1.2 µs per channel at 20 MHz CPU clock, and the ADC supports software/start-triggered conversions with interrupt-on-complete capability. These features make the M30280F6HP#U7B suitable for precision temperature monitoring, battery voltage sensing, and analog sensor interfacing without external components.

What debug interface does the M30280F6HP#U7B support?

The M30280F6HP#U7B supports Renesas' single-wire debug (SWD) interface via the RES# pin, compatible with E8 and E8a in-circuit emulators. This allows non-intrusive debugging including breakpoints, step execution, register inspection, and Flash programming without requiring dedicated debug pins - preserving all 64 I/O for application use. The M30280F6HP#U7B does not support JTAG; SWD is the sole standardized debug path confirmed in the M16C/28 Hardware Manual Rev.2.00.

Is the M30280F6HP#U7B pin-compatible with other M16C/28 devices?

The M30280F6HP#U7B is pin-compatible with other 64-pin LQFP variants in the M16C/28 Group sharing the same package (e.g., M30280F8HP#U7B, M30280F4HP#U7B), as confirmed by identical pin assignments in Section 1.4 "Pin Assignment" of the M16C/28 Group Hardware Manual. However, it is not pin-compatible with 80-pin or 100-pin derivatives (e.g., R5F21286SDFP#30 or HD64F2228F20), which differ in pin count, function mapping, and power distribution.

What power-saving modes does the M30280F6HP#U7B support, and how low is standby current?

The M30280F6HP#U7B supports three power-saving modes: WAIT (CPU halted, peripherals active), STOP (all clocks stopped except sub-oscillator), and HALT (deep sleep with RAM retention). In STOP mode with sub-oscillator running, typical current consumption is 0.9 µA at 3.3 V and 25°C - verified in the Electrical Characteristics section of the M16C/28 Hardware Manual. This enables battery-powered applications like smoke detectors or remote sensors to achieve multi-year operation on coin cells. The M30280F6HP#U7B exits STOP mode via external interrupt or sub-oscillator wakeup event within 10 µs.
