NXP Semiconductors MC56F82743VFM

Overview

MC56F82743VFM from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EX core, operating at up to 100 MHz in fast mode with 64 KB flash and 8 KB RAM. It integrates dual 12-bit ADCs (8-channel each), four analog comparators with 6-bit DAC references, two 12-bit DACs, and one eFlexPWM module supporting up to 8 high-resolution PWM outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation where deterministic real-time control and analog integration are critical.

For engineers reviewing the MC56F82743VFM datasheet, MC56F82743VFM pinout, MC56F82743VFM application, or MC56F82743VFM equivalent, key selection criteria include its 32-pin QFN package, V-temperature grade (–40°C to 105°C), 3.3 V single-supply operation with 5 V–tolerant I/O, and support for NanoEdge PWM placement, dual ADC synchronization via crossbar, and MSCAN interface - all confirmed for this exact variant.

Technical Context

The MC56F82743VFM implements the 56800EX core with modified dual-Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle, delivering up to 100 MIPS. Its peripheral set is defined by fixed allocation: two 12-bit cyclic ADCs (8-channel each), four comparators (each with 6-bit DAC reference), two 12-bit DACs, one eFlexPWM with 8 high-res channels, two QSCI modules, two QSPI modules, one I²C/SMBus port, and one MSCAN module - all active and verified for this part number.

System-level timing relies on multiple clock sources: an 8 MHz/400 kHz relaxation oscillator, 200 kHz low-power oscillator, crystal/resonator input (4–16 MHz), and a PLL generating 200–400 MHz. Memory protection includes MRP unit and flash security; safety features comprise windowed COP watchdog, EWM, CRC generator, and brown-out reset - all documented as functional for MC56F82743VFM in the family datasheet.

FAQ

What is the maximum operating frequency of the MC56F82743VFM core?

The MC56F82743VFM core operates at up to 100 MHz in fast mode, delivering 100 MIPS performance. This frequency is achieved using the on-chip PLL with an input reference clock of 8–16 MHz. The device also supports 50 MHz operation in normal mode. Both modes are fully supported for the MC56F82743VFM variant as specified in the MC56F827XXDS Rev. 4.1 datasheet.

Does the MC56F82743VFM support CAN communication?

Yes, the MC56F82743VFM includes a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0A/B protocol, supporting standard and extended frames, up to 8 bytes per message, and programmable bit rates up to 1 Mbps. This functionality is explicitly confirmed for MC56F82743VFM in Table 1 of the MC56F827XXDS datasheet.

What analog peripherals are integrated into the MC56F82743VFM?

The MC56F82743VFM integrates two independent 12-bit cyclic ADCs (8-channel each with x1/x2/x4 programmable gain amplifiers), four analog comparators (each with a 6-bit DAC reference), and two 12-bit DACs. These peripherals are fully functional and validated for this specific part number, enabling sensor signal conditioning and closed-loop control without external components.

What is the package type and thermal specification of the MC56F82743VFM?

The MC56F82743VFM uses a 32-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. It is rated for operation from –40°C to +105°C (V temperature option) and requires a 2.2 µF capacitor on the VCAP pin. This package information is explicitly assigned to MC56F82743VFM in the MC56F827XXDS Rev. 4.1 pinout tables.

How does the MC56F82743VFM handle system safety and reliability?
