NXP Semiconductors MC56F82736VLFR

Overview

MC56F82736VLFR 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 and MCU functionality with 48 KB flash memory, 8 KB RAM, dual 12-bit ADCs (8-channel each), two 12-bit DACs, and an eFlexPWM module supporting up to 8 high-resolution PWM outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation systems requiring deterministic real-time response.

For engineers reviewing the MC56F82736VLFR datasheet, MC56F82736VLFR pinout, MC56F82736VLFR application, or MC56F82736VLFR equivalent, key selection criteria include its 48-pin LQFP package, -40°C to 105°C V-temperature grade, 3.0–3.6 V supply, 5 V–tolerant I/O (except RESETB), and support for QSCI/QSPI/I²C/MSCAN interfaces in safety-critical embedded control designs.

Technical Context

The MC56F82736VLFR implements the 56800EX core with modified dual-Harvard architecture-three address buses, four data buses (two 32-bit primary), and single-cycle 32×32→64-bit MAC-to deliver up to 100 MIPS. Its unified C-efficient instruction set supports both fractional/integer arithmetic and hardware DO/REP loops for efficient motor control algorithms.

Peripherals are interconnected via dual inter-module crossbar switches enabling flexible routing of ADC triggers, PWM sync signals, comparator outputs, and timer events. The eFlexPWM submodule provides independent deadtime insertion, double-buffered registers, and NanoEdge placement for precise timing in BLDC commutation and resonant LLC control.

Key Specifications

Pinout & Package

MC56F82736VLFR is housed in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are multiplexed via GPIOx_PER and SIM GPSx registers; all pins default to GPIO input after reset except JTAG and RESETB.

FAQ

What is the maximum operating frequency of the MC56F82736VLFR core?

The MC56F82736VLFR 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 between 8 MHz and 16 MHz. The device also supports 50 MHz operation in normal mode for lower-power applications. All timing specifications-including ADC conversion rate, PWM resolution, and peripheral bus speeds-are validated at this maximum core frequency.

Does the MC56F82736VLFR support CAN communication?

Yes, the MC56F82736VLFR includes a fully compliant Modular/Scalable Controller Area Network (MSCAN) module supporting CAN 2.0A/B protocols, standard and extended frames, bit rates up to 1 Mbit/s, and features such as message buffering, timestamping, and listen-only mode. This makes MC56F82736VLFR suitable for industrial fieldbus networks and distributed control systems requiring robust, noise-immune communication.

What are the analog input capabilities of the MC56F82736VLFR?

The MC56F82736VLFR integrates two independent 12-bit cyclic ADCs, each supporting up to 8 external analog inputs. Each ADC includes a programmable gain amplifier (x1/x2/x4), 100 ns minimum conversion period, and support for single-ended, differential, and unipolar differential modes. ADC conversions can be hardware-triggered by PWM, timers, or comparators via the inter-module crossbar, enabling precise synchronous sampling in motor control and power conversion applications.

Is the MC56F82736VLFR pin-compatible with other members of the MC56F827xx family?

No, the MC56F82736VLFR is not universally pin-compatible across the MC56F827xx family. While it shares the 48-pin LQFP package with MC56F82746VLF and MC56F82726VLF, pin assignments differ significantly-especially for peripheral signals like QSCI, QSPI, and MSCAN. For example, MSCAN_TX/RX appear on pins 35/36 in MC56F82736VLFR but are absent in MC56F82726VLF. Always verify pinout diagrams in the MC56F827XXDS datasheet before board reuse.

What safety certifications apply to the MC56F82736VLFR?

The MC56F82736VLFR incorporates multiple hardware safety features aligned with EN60730 Class B and IEC61508 SIL2 requirements, including a windowed COP watchdog with selectable clock sources (ROSC, crystal, bus), External Watchdog Monitor (EWM) with independent safe-state output, CRC generator for memory integrity checking, and brown-out reset with critical low-voltage interrupt. These features are documented in NXP's safety manual for the MC56F827xx family and validated under V-temperature grade (-40°C to +105°C).
