NXP Semiconductors MC56F82726VLFR

Overview

MC56F82726VLFR 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 32 KB flash memory, 6 KB RAM, dual 12-bit ADCs (8-channel each), two 12-bit DACs, and one eFlexPWM module with 8 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 MC56F82726VLFR datasheet, MC56F82726VLFR pinout, MC56F82726VLFR application, or MC56F82726VLFR equivalent, key selection criteria include its 48-pin LQFP package, -40°C to 105°C V-temperature grade, 3.0–3.6 V single supply, 5 V–tolerant I/O (excluding RESETB), and support for QSCI, QSPI, I²C, and MSCAN interfaces in safety-critical control designs.

Technical Context

The MC56F82726VLFR implements the 56800EX core with modified dual-Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle. It delivers up to 100 MIPS via a 100 MHz core clock, supported by hardware MAC, 32-bit ALU, and zero-overhead context switching using nine shadow registers.

Its peripheral set centers on deterministic control: the eFlexPWM supports independent edge control, deadtime insertion, and fault management across 8 outputs; dual 12-bit ADCs feature programmable x1/x2/x4 gain amplifiers and crossbar-synchronized triggering; and the inter-module crossbar enables flexible routing between ADCs, comparators, DACs, timers, and GPIOs without CPU intervention.

FAQ

What is the maximum operating frequency of the MC56F82726VLFR core?

The MC56F82726VLFR core supports 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 input. The device also supports 50 MHz operation in normal mode for lower-power applications. All timing specifications in the MC56F827XXDS datasheet are validated at 100 MHz for the MC56F82726VLFR.

Does the MC56F82726VLFR support CAN communication?

Yes, the MC56F82726VLFR 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 bit rates up to 1 Mbit/s. It features individual Rx mask registers, time-stamped message logging, and programmable wakeup on bus activity-key for industrial networked control systems using MC56F82726VLFR.

What are the analog input capabilities of the MC56F82726VLFR?

The MC56F82726VLFR integrates two independent 12-bit cyclic ADCs, each with 8 external input channels and a programmable x1/x2/x4 gain amplifier. Each ADC supports sequential, parallel, or independent scan modes; single conversion time is 10 ADC clock cycles (≤100 ns at 10 MHz); and conversions can be triggered synchronously via eFlexPWM, timers, or GPIO-enabling precise current/voltage sensing in MC56F82726VLFR-based motor drives.

Is the MC56F82726VLFR pin-compatible with other members of the MC56F827xx family?

No, the MC56F82726VLFR is not pin-compatible with other MC56F827xx variants. It uses a 48-pin LQFP package, whereas MC56F82728VLH uses 64-pin LQFP and MC56F82733VLC uses 32-pin LQFP. Pin assignments differ across packages-even shared signal names map to different physical pins. Migration requires PCB redesign; software reuse is possible due to identical peripheral register maps and core architecture in MC56F82726VLFR.

What safety features does the MC56F82726VLFR include for industrial applications?

The MC56F82726VLFR includes Windowed Computer Operating Properly (COP) watchdog and External Watchdog Monitor (EWM), both qualified to EN60730 Class B and aligned with IEC61508 requirements. The COP operates in all power modes and supports selectable clock sources; the EWM provides independent safe-mode output assertion (EWM_OUT_b) upon timeout. These features, combined with hardware CRC and memory protection, make MC56F82726VLFR suitable for SIL2-capable industrial control systems.
