Renesas M30281F8HP

Overview

M30281F8HP from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/28 Group, featuring the M16C/60 series CPU core, 64 KB + 4 KB flash program memory, 4 KB RAM, and 55 I/O lines in an 80-pin LQFP package. It supports 20 MHz operation at 3.0–5.5 V, integrates a 10-bit A/D converter with 13 channels, dual DMAC channels, and multifunction timers for motor control and industrial automation.

For engineers reviewing the M30281F8HP datasheet, M30281F8HP pinout, M30281F8HP application, or M30281F8HP equivalent, key selection criteria include its 80-pin PLQP0080KB-A LQFP package, 20 MHz BCLK capability at 3.0 V minimum supply, 13-channel 10-bit ADC, UART/I²C/IEBus serial interfaces, and suitability for inverter-based home appliances and office equipment motor control.

Technical Context

The M30281F8HP implements the M16C/60 CPU core with 91 basic instructions and executes a minimum instruction in 50 ns at 20 MHz (VCC = 3.0–5.5 V). It operates exclusively in single-chip mode with a 1-Mbyte address space and includes four clock generation circuits: main clock, sub-clock, on-chip oscillator, and PLL frequency synthesizer - the latter required for 24 MHz operation in M16C/28B variants.

Peripheral integration includes TimerA (16-bit × 5), TimerB (16-bit × 3), TimerS (16-bit base timer with 8 input capture/output compare channels), three UARTs (UART0–2), two clock-synchronous SI/O channels, one multi-master I²C bus, and a watchdog timer with 15-bit counter and prescaler. The device supports up to 24 interrupt sources (24 internal + 8 external) across 7 priority levels.

FAQ

What is the maximum operating frequency and supply voltage range for the M30281F8HP?

The M30281F8HP operates at up to 20 MHz BCLK with a supply voltage range of 3.0 V to 5.5 V. It achieves a minimum instruction execution time of 50 ns under these conditions. The device does not support 24 MHz operation - that capability is reserved for M16C/28B variants with PLL synthesis, and the M30281F8HP is a Normal-ver. part in the M16C/28 family. Its electrical characteristics are fully specified across the −20 °C to +85 °C ambient temperature range.

Does the M30281F8HP include an analog-to-digital converter, and how many channels does it support?

Yes, the M30281F8HP integrates a 10-bit successive-approximation ADC supporting 13 analog input channels (AN00–AN12). Conversion time is ≤ 1.2 µs, and triggers can be sourced from software, external pins, or internal timers. The ADC uses dedicated AVcc and AVss supplies with CNVss for noise reduction, and its reference voltage (VREF) is externally configurable. This matches the 64-pin package specification confirmed in Table 1.2 of the M16C/28 hardware manual.

What package type and pin count does the M30281F8HP use?

The M30281F8HP uses an 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. This is explicitly confirmed in Figure 1.6 (pin assignment) and Table 1.4 (M16C/28B product list), where "HP" in the part number denotes this LQFP variant. It is distinct from the 64-pin and 85-pin TFLGA packages offered in the same family.

Which serial communication protocols are supported by the M30281F8HP?

The M30281F8HP supports UART (3 channels: UART0, UART1, UART2), clock-synchronous serial I/O (2 channels: SI/O3, SI/O4), multi-master I²C bus (1 channel), and IEbus (1 channel via UART2 function select). Protocol selection is pin-muxed and register-controlled - for example, UART2 can be configured as UART, clock-synchronous, I²C, or IEbus. All are implemented in hardware with DMA support, and no external transceivers are required for standard voltage-level operation.

Is the M30281F8HP suitable for automotive or safety-critical applications?

No, the M30281F8HP is classified as a Standard-grade Renesas product intended for computers, office equipment, communications devices, audio/video gear, home appliances, and industrial robots. It is not qualified for High Quality or Specific applications such as automotive ECUs, medical life-support systems, or aerospace. Its operating temperature range (−20 °C to +85 °C) and qualification scope align strictly with consumer and industrial appliance use cases, as defined in Renesas Notice #7.
