MC56F82743VFM

Product Overview

The NXP USA Inc. MC56F82743VFM is a 32-bit microcontroller from the 56F8xxx series, based on the 56800EX core and specified at 100MHz. It provides 64KB (32K x 16) of FLASH program memory, 4K x 16 of RAM, and 26 I/O pins. The device includes an internal oscillator, operates from 2.7V to 3.6V, and uses a 32-HVQFN (5x5) surface-mount package with wettable flank. Connectivity includes I2C, SCI, and SPI, while integrated peripherals include DMA, POR, PWM, WDT, six 12-bit ADC channels, and two 12-bit DAC channels.

Key Features

• 56800EX 32-bit core with 100MHz speed
• 64KB (32K x 16) FLASH program memory and 4K x 16 RAM
• 26 I/O pins
• I2C, SCI, and SPI connectivity
• DMA, POR, PWM, and WDT peripherals
• A/D 6x12b and D/A 2x12b data converters
• 2.7V to 3.6V supply voltage and -40°C to 105°C operating temperature (TA)
• 32-HVQFN (5x5) surface-mount package with wettable flank

Applications

• Motor and actuator control systems that use PWM outputs and analog feedback
• Power conversion or signal conditioning circuits requiring 12-bit ADC and DAC channels
• Control nodes communicating over I2C, SCI, or SPI serial interfaces
• Instrumentation or measurement interfaces with multiple analog inputs, outputs, and I/O pins

Design & Procurement Notes

Design teams should plan the supply network for 2.7V to 3.6V and account for the 32-HVQFN (5x5) wettable-flank surface-mount package during PCB layout and inspection. The internal oscillator should be considered when defining clock requirements, while the 100MHz core, 64KB FLASH, 4K x 16 RAM, and 26 I/O pins should be checked against the required code size, data buffers, and peripheral count. Serial interfaces (I2C, SCI, SPI), DMA, PWM, POR, WDT, and the 12-bit ADC/DAC channels affect board-level signal routing and firmware resource allocation. The -40°C to 105°C operating temperature range is a design input for thermal and enclosure planning.
