NXP Semiconductors MC56F82733VLC

Overview

MC56F82733VLC 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. It integrates DSP performance (100 MIPS) with MCU functionality, 48 KB flash, 8 KB RAM, dual 12-bit ADCs (8-channel each), and an eFlexPWM module with 8 high-resolution outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation.

For engineers reviewing the MC56F82733VLC datasheet, MC56F82733VLC pinout, MC56F82733VLC application, or MC56F82733VLC equivalent, key selection criteria include its V-temp grade (-40°C to 105°C), 32-pin LQFP package, single 3.3 V supply, 5 V–tolerant I/O (excluding RESETB), and MSCAN omission-critical for CAN-based designs requiring external transceivers.

Technical Context

The MC56F82733VLC implements the 56800EX core with modified dual-Harvard architecture, supporting concurrent instruction fetches and dual data accesses per cycle. Its unified C-efficient design delivers both fractional/integer arithmetic and hardware MAC (16×16→32, 32×32→64) for real-time control loops.

Peripherals are interconnected via dual inter-module crossbars enabling flexible routing of ADC triggers, PWM synchronization, comparator outputs, and DAC references. The device lacks MSCAN but includes two QSCI modules with LIN slave support, two QSPI interfaces, one I²C/SMBus port, and a CRC generator compliant with CRC16-CCITT.

FAQ

What is the maximum operating frequency of the MC56F82733VLC core?

The MC56F82733VLC core operates at up to 100 MHz in fast mode, delivering 100 million instructions per second (MIPS). This frequency is achieved using the internal PLL with an 8–16 MHz crystal input. In normal mode, the core runs at up to 50 MHz. The 100 MHz capability enables sub-microsecond execution of field-oriented control loops and high-frequency PWM modulation essential for modern power electronics.

Does the MC56F82733VLC include a Controller Area Network (CAN) interface?

No, the MC56F82733VLC does not include an MSCAN module. Unlike higher-tier variants such as MC56F82743VLC, this part omits CAN functionality. Systems requiring CAN communication must implement an external CAN transceiver connected via GPIO or UART-based protocols like LIN (which is supported via QSCI with slave functionality). This omission reduces cost and silicon area for applications where CAN is unnecessary.

What are the analog input capabilities of the MC56F82733VLC?

The MC56F82733VLC features two independent 12-bit cyclic ADCs, each with 8 external input channels and a programmable x1/x2/x4 pre-amplifier. It supports single-ended and differential acquisition, sequential/parallel scanning, and hardware-triggered simultaneous sampling. Conversion time is 10 ADC clock cycles (minimum 100 ns period), enabling high-fidelity current and voltage sensing in motor control and power supply applications.

How is the MC56F82733VLC protected against power supply faults?

The MC56F82733VLC integrates a comprehensive power supervisor with power-on reset (POR) activation above 2.7 V, brown-out reset (BOR) at 2.0 V, and dual low-voltage interrupts (LVI) at 2.2 V (critical warn) and 2.7 V (peripheral warn). These features ensure deterministic startup, safe shutdown during undervoltage events, and early warning for firmware-initiated graceful degradation - critical for industrial and medical equipment compliance.

Can the MC56F82733VLC generate arbitrary waveforms using its DACs?

Yes, the MC56F82733VLC includes two 12-bit DACs (DACA and DACB) with automatic waveform generation capability. Each DAC can produce pre-programmed square, triangle, or sawtooth waveforms with programmable period, update rate, and amplitude range. Waveform outputs can be routed internally to comparators or ADCs (e.g., for slope compensation in SMPS) or externally via dedicated pins, eliminating need for external function generators.
