NXP Semiconductors MC56F82733VFM

Overview

MC56F82733VFM 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 48 KB flash memory, 8 KB RAM, dual 12-bit ADCs (8-channel each), two 12-bit DACs, and an eFlexPWM module with 8 high-resolution outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation requiring deterministic real-time processing.

For engineers reviewing the MC56F82733VFM datasheet, MC56F82733VFM pinout, MC56F82733VFM application, or MC56F82733VFM equivalent, key selection criteria include its V-temp grade (-40°C to 105°C), 32-pin QFN package, 5 V–tolerant I/O (except RESETB), dual QSCI/QSPI interfaces, and MSCAN support - all critical for embedded power electronics and safety-aware control systems.

Technical Context

The MC56F82733VFM implements the 56800EX core with dual Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle. Its unified DSP/MCU instruction set supports fractional arithmetic, single-cycle 32×32→64-bit MAC, and hardware DO/REP loops - optimized for motor FOC and digital power control algorithms.

Peripherals are interconnected via dual inter-module crossbar switches, allowing flexible routing of ADC triggers to eFlexPWM, comparator outputs to DAC references, and timer events to GPIO. The device includes windowed COP and EWM watchdogs compliant with EN60730 and IEC61508, plus CRC-16-CCITT hardware for firmware integrity verification.

FAQ

What is the maximum operating frequency of the MC56F82733VFM core?

The MC56F82733VFM core operates at up to 100 MHz in fast mode, delivering 100 MIPS performance. This frequency is achieved using the internal PLL with an 8–16 MHz crystal oscillator input. The device also supports 50 MHz operation in normal mode for lower-power applications. All timing specifications in the MC56F827xx datasheet are validated at this 100 MHz maximum frequency for the V-grade temperature range.

Does the MC56F82733VFM support CAN communication?

Yes, the MC56F82733VFM includes a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0 A/B protocol, supporting standard and extended frames, programmable bit rates up to 1 Mbit/s, and message buffering with individual mask registers. However, note that MSCAN is only present in MC56F827xx variants with "V" or "M" suffixes and 64/48-pin packages - the 32-pin QFN MC56F82733VFM does not include MSCAN functionality per the official MC56F827XXDS Rev. 4.1 feature table.

What package type and pin count does the MC56F82733VFM use?

The MC56F82733VFM uses a 32-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. This matches the "FM" suffix designation in NXP's part numbering scheme. Pin assignments are defined in Section 2 of the MC56F827XXDS datasheet and include dedicated VDDA/VSSA analog supplies, VCAP core regulator output, JTAG debug signals, and multiplexed GPIO/peripheral functions.

How much on-chip memory does the MC56F82733VFM have?

The MC56F82733VFM integrates 48 KB of on-chip flash memory and 8 KB of dual-port data/program RAM. Flash memory supports security features and in-application programming; RAM is accessible simultaneously by the CPU and DMA controller. Memory mapping allows both program and data spaces to access flash and RAM, enabling flexible code and data partitioning for real-time control tasks.

Is the MC56F82733VFM compatible with 5 V logic interfaces?

Yes, all general-purpose I/O pins on the MC56F82733VFM are 5 V–tolerant except the RESETB pin, which is strictly 3.3 V only. This allows direct connection to 5 V sensors, optocouplers, and legacy logic without external level shifters - reducing BOM cost and board space. The 5 V tolerance applies across the full V-grade operating temperature range (-40°C to +105°C).
