NXP Semiconductors MC56F82743VLC

Overview

MC56F82743VLC 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), three analog comparators, two 12-bit DACs, and one eFlexPWM module with eight high-resolution NanoEdge PWM outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial embedded systems requiring deterministic real-time processing.

For engineers reviewing the MC56F82743VLC datasheet, MC56F82743VLC pinout, MC56F82743VLC application, or MC56F82743VLC equivalent, key selection criteria include its 32-pin LQFP package, V-temp grade (–40°C to 105°C), single 3.3 V supply, 5 V–tolerant I/O (excluding RESETB), and support for QSCI, QSPI, I²C, and crossbar-based peripheral interconnect - all critical for compact, cost-sensitive control designs.

Technical Context

The MC56F82743VLC implements the 56800EX core with modified dual-Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle. Its unified DSP/MCU instruction set supports fractional arithmetic, hardware MAC (16×16→32, 32×32→64), and zero-overhead context switching via full register shadowing.

Peripherals are tightly coupled via inter-module crossbar and AND-OR-INVERT logic, allowing flexible routing of ADC triggers, PWM fault inputs, comparator outputs, and timer events without software intervention. The eFlexPWM submodule provides independent deadtime insertion, double-buffered registers, and FORCE_OUT synchronization - essential for precise gate drive timing in motor and power conversion applications.

Key Specifications

FAQ

What is the maximum operating frequency of the MC56F82743VLC core?

The MC56F82743VLC 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. In normal mode, the core runs at up to 50 MHz. The device supports dynamic switching between modes to balance performance and power consumption in the MC56F82743VLC application.

Does the MC56F82743VLC support CAN bus communication?

No, the MC56F82743VLC does not include the MSCAN module. Per the MC56F827xx family datasheet, MSCAN is only available on variants with part numbers ending in '748', '746', or '738' - not on MC56F82743VLC. Engineers requiring CAN must select MC56F82746MLF or MC56F82748VLH instead. The MC56F82743VLC provides QSCI, QSPI, and I²C for local interconnect.

What are the analog input capabilities of the MC56F82743VLC?

The MC56F82743VLC integrates two independent 12-bit cyclic ADCs, each with 8 external input channels and a programmable gain amplifier (x1/x2/x4). Each ADC supports sequential, parallel, and independent scan modes, with conversion times as low as 10 ADC clock cycles. ADC results can be triggered by PWM, timers, or software, and the MC56F82743VLC crossbar enables hardware-synchronized sampling across both ADCs.

How many PWM outputs does the MC56F82743VLC support, and what is their resolution?

The MC56F82743VLC features one eFlexPWM module supporting up to 8 PWM outputs, all with 16-bit resolution and NanoEdge placement for sub-nanosecond edge control. These outputs can be configured as four complementary pairs or eight independent signals, with independent deadtime, polarity, and reload control. The MC56F82743VLC also supports FORCE_OUT synchronization to update all outputs simultaneously.

What is the temperature range and package type of the MC56F82743VLC?

The MC56F82743VLC is rated for operation from –40°C to +105°C (V temperature option) and is supplied in a 32-pin LQFP package (7 mm × 7 mm, 0.8 mm pitch). This package includes an exposed pad for thermal dissipation and is compatible with standard surface-mount assembly processes. The MC56F82743VLC datasheet specifies this as the only package option for this specific part number.
