MC56F82728VLH from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EX core, delivering up to 100 MIPS at 100 MHz in fast mode. It integrates dual 12-bit ADCs (2×8 channels), two 12-bit DACs, four analog comparators with 6-bit DAC references, one eFlexPWM module with 8 high-resolution NanoEdge PWM outputs, and supports industrial motor control (BLDC/PMSM), switched-mode power supplies, and photovoltaic systems.

For engineers reviewing the MC56F82728VLH datasheet, MC56F82728VLH pinout, MC56F82728VLH application, or MC56F82728VLH equivalent, key selection criteria include its 32 KB flash/6 KB RAM configuration, 64-pin LQFP package, -40°C to 105°C V-temperature grade, 3.0–3.6 V supply, and integrated MSCAN, QSCI, QSPI, and I²C interfaces for real-time embedded control.

Technical Context

The MC56F82728VLH implements the 56800EX core with modified dual-Harvard architecture-three address buses, four data buses (two 32-bit primary), and support for concurrent instruction fetch + dual data access per cycle. Its eFlexPWM module provides independent top/bottom deadtime insertion per complementary pair and hardware-synchronized submodule triggering.

Analog subsystem includes two 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers, 10 MHz max clock, and 10-cycle single conversion time; plus two 12-bit DACs supporting automatic waveform generation (square/triangle/sawtooth) for slope compensation in power conversion.

FAQ

What is the maximum operating frequency of the MC56F82728VLH core?

The MC56F82728VLH 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 8–16 MHz crystal reference input. The device also supports 50 MHz operation in normal mode for lower-power applications. All timing-critical peripherals-including eFlexPWM, ADC, and timers-are fully synchronized to this clock domain, ensuring deterministic behavior in real-time control loops executed by the MC56F82728VLH.

Does the MC56F82728VLH support CAN communication?

Yes, the MC56F82728VLH includes a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0A/B protocol, supporting standard/extended frames, up to 8-byte payloads, and programmable bit rates up to 1 Mbit/s. This module is fully integrated into the MC56F82728VLH's crossbar architecture, enabling direct routing of CAN messages to DMA or interrupt handlers without CPU intervention-critical for time-sensitive industrial networking.

What analog peripherals are integrated into the MC56F82728VLH?

The MC56F82728VLH integrates two independent 12-bit cyclic ADCs (2×8 external channels), two 12-bit DACs, and four analog comparators each with a 6-bit programmable DAC reference. The ADCs support programmable x1/x2/x4 gain amplification, 10 MHz max clock, and 10-cycle conversion time. These analog resources are directly accessible via the inter-module crossbar, allowing synchronous triggering from eFlexPWM or timers-key for accurate current sensing and feedback in motor control applications using the MC56F82728VLH.

What is the package type and pin count of the MC56F82728VLH?

The MC56F82728VLH is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package provides 54 GPIOs, including 5 V–tolerant I/Os (except RESETB), and supports full peripheral mapping-including dual QSCI, dual QSPI, I²C, MSCAN, eFlexPWM, and analog interfaces. The 64-pin LQFP variant ensures mechanical stability and thermal performance required for industrial environments where the MC56F82728VLH is commonly deployed.

How does the MC56F82728VLH handle power supply supervision and safety monitoring?

The MC56F82728VLH incorporates integrated power supervision with power-on reset (POR), brown-out reset (BOR) at 2.0 V, and low-voltage interrupts (LVI) at 2.2 V (critical warn) and 2.7 V (peripheral warn). It also features a windowed COP watchdog and External Watchdog Monitor (EWM) with independent safe-mode output-both configurable for EN60730 and IEC61508 compliance. These features operate across all power modes and are essential for fail-safe operation in safety-critical applications controlled by the MC56F82728VLH.
