NXP Semiconductors MC56F84565VLKR

Overview

MC56F84565VLKR from NXP Semiconductors (formerly Freescale) is a 32-bit digital signal controller (DSC) built on the 56800EX core, delivering up to 80 MIPS at 80 MHz. It integrates DSP and MCU functionality with dual 12-bit ADCs (8-channel each), one 16-bit SAR ADC (20-channel), four analog comparators with 6-bit DAC references, one 12-bit DAC, two eFlexPWM modules (up to 24 outputs), FlexCAN, three QSCI, three QSPI, and two I²C interfaces. It targets motor control (BLDC, PMSM), industrial power conversion, and smart sensor systems.

For engineers reviewing the MC56F84565VLKR datasheet, MC56F84565VLKR pinout, MC56F84565VLKR application, or MC56F84565VLKR equivalent, key selection criteria include its 80-pin LQFP package, 3.0–3.6 V single-supply operation, 5 V–tolerant I/O (except RESETB), 256 KB flash + 32 KB FlexNVM, 32 KB RAM, and support for real-time control loops requiring sub-300 ns ADC conversion time and hardware-accelerated PWM deadtime management.

Technical Context

The MC56F84565VLKR implements the 56800EX core with modified dual-Harvard architecture-three address buses, four data buses (two 32-bit primary), and concurrent instruction fetch + dual data access per cycle. Its 80 MHz operation enables deterministic execution of complex control algorithms with hardware DO/REP loops and bit-reverse addressing for FFT acceleration.

Peripheral integration centers on real-time signal conditioning and actuation: dual high-speed ADCs synchronize to PWM events via inter-module crossbar; eFlexPWM submodules provide independent top/bottom deadtime insertion and FORCE_OUT simultaneous output control; FlexCAN supports 1 Mbps CAN 2.0A/B frames with 16 configurable message buffers and timestamping.

Key Specifications

Pinout & Package

MC56F84565VLKR is housed in an 80-pin LQFP (12 × 12 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments follow Freescale's MC56F8458X/MC56F8456X family layout, where primary functions are active after reset and alternate functions require GPIO/SIM register configuration.

FAQ

What is the maximum operating frequency and temperature range for the MC56F84565VLKR?

The MC56F84565VLKR operates at up to 80 MHz across an ambient temperature range of –40 °C to +105 °C. This rating is validated per Freescale's MC56F8458X/MC56F8456X Data Sheet Rev. 3 (June 2014), with VDD supply maintained between 3.0 V and 3.6 V. The device uses internal thermal monitoring and brown-out reset to maintain functional safety under these conditions.

Does the MC56F84565VLKR support 5 V–tolerant I/O pins?

Yes, the MC56F84565VLKR features 5 V–tolerant I/O on all pins except RESETB. This allows direct interfacing with legacy 5 V logic, sensors, and communication transceivers without level-shifting circuitry-reducing BOM cost and board space. The tolerance is specified under DC electrical characteristics in the official datasheet.

How many analog-to-digital converters does the MC56F84565VLKR integrate, and what are their key specifications?

The MC56F84565VLKR integrates three ADC subsystems: two 12-bit cyclic ADCs (ADCA and ADCB) with 8 channels each and 300 ns conversion time, plus one 16-bit SAR ADC (ADCC) with 20 channels. All support programmable gain, differential/single-ended input, and crossbar-triggered sampling-enabling simultaneous current, voltage, and temperature acquisition in motor control applications.

What PWM capabilities does the MC56F84565VLKR provide for motor control applications?

The MC56F84565VLKR includes two eFlexPWM modules supporting up to 24 outputs with 16-bit resolution, independent deadtime insertion per complementary pair, FORCE_OUT synchronous update, and fault-input mapping. These features directly support 3-phase inverter gate driving with hardware-enforced shoot-through prevention and real-time torque ripple reduction in BLDC and PMSM systems.

Is the MC56F84565VLKR pin-compatible with other members of the MC56F845xx family?

The MC56F84565VLKR shares the same 80-pin LQFP package and pinout with MC56F84567VLL and MC56F84585VLK, as confirmed in Table 2 of the MC56F8458X/MC56F8456X datasheet. However, feature enablement (e.g., PWMA high-res channels) differs across variants, so firmware and peripheral initialization must match the specific part's capabilities.
