NXP Semiconductors MC56F82738VLH

Overview

MC56F82738VLH 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), four analog comparators with 6-bit DAC references, and one eFlexPWM module with 8 high-resolution NanoEdge PWM outputs. It targets motor control (BLDC/PMSM), switched-mode power supplies, and industrial automation where deterministic real-time control and analog integration are critical.

For engineers reviewing the MC56F82738VLH datasheet, MC56F82738VLH pinout, MC56F82738VLH application, or MC56F82738VLH equivalent, key selection criteria include its 64-pin LQFP package, -40°C to 105°C V-temp grade, 3.3 V single supply with 5 V–tolerant I/O, dual QSCI/QSPI interfaces, and MSCAN support - all validated for industrial and appliance-grade embedded control.

Technical Context

The MC56F82738VLH implements the 56800EX core with modified dual-Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle. Its unified DSP/MCU architecture delivers 100 MIPS at 100 MHz while supporting fractional arithmetic, hardware MAC, and zero-overhead context switching via full register shadowing.

Peripherals are tightly coupled via inter-module crossbar and AND-OR-INVERT logic, allowing flexible routing of ADC triggers to eFlexPWM, comparator outputs to DACs, or timer events to GPIO. The device supports synchronized multi-module operation - e.g., ADC conversions triggered by PWM edge events, with results fed directly into closed-loop control algorithms.

Key Specifications

Pinout & Package

MC56F82738VLH is housed in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) package with exposed thermal pad.

FAQ

What is the maximum operating frequency of the MC56F82738VLH core?

The MC56F82738VLH 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 input. The device also supports 50 MHz operation in normal mode for lower-power applications. All timing specifications in the MC56F827xx datasheet Rev. 4.1 are validated for this 100 MHz operation, including ADC conversion rates and PWM resolution.

Does the MC56F82738VLH support CAN communication?

Yes, the MC56F82738VLH includes a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0A/B protocol, supporting standard and extended frames, up to 1 Mbit/s bit rate, and programmable message buffering. This capability is confirmed in Table 1 of the MC56F827xx datasheet Rev. 4.1, which lists MSCAN as present for the MC56F82738VLH variant within the 64-pin LQFP group.

What are the analog input capabilities of the MC56F82738VLH?

The MC56F82738VLH features two independent 12-bit cyclic ADCs, each with 8 external input channels and a programmable gain amplifier (x1, x2, or x4). It supports single-ended and differential acquisition modes, with sequential/parallel scan and hardware-triggered conversions synchronized to PWM or timer events. These specifications are explicitly listed for MC56F82738VLH in Table 1 of the MC56F827xx datasheet Rev. 4.1.

Is the MC56F82738VLH pin-compatible with other MC56F827xx family members?

MC56F82738VLH is pin-compatible with other 64-pin LQFP variants in the MC56F827xx family, including MC56F82748VLH and MC56F82728VLH, sharing identical pinout, package dimensions, and signal mapping per Section 11 of the MC56F827xx datasheet Rev. 4.1. However, peripheral enablement (e.g., MSCAN, QSPI count) and memory size differ between variants, requiring firmware adaptation despite mechanical compatibility.

What temperature range is specified for the MC56F82738VLH?

The MC56F82738VLH is rated for operation from -40°C to 105°C, designated by the 'V' temperature option in its part number suffix. This specification is confirmed in Table 1 of the MC56F827xx datasheet Rev. 4.1 and applies to all electrical characteristics including flash endurance, ADC accuracy, and PWM timing stability under industrial ambient conditions.
