MC56F81768LVLH

Digital Signal Processor Dsp Overview

The MC56F81768LVLH is a digital signal controller (DSC) from NXP Semiconductors, part of the MC56F81xxxL family. It integrates a 32-bit 56800EX core operating at up to 100 MHz in fast mode, providing 100 MIPS performance. The device features 128 KB of on-chip flash memory and 20 KB of data/program RAM. Key analog peripherals include two independent 12-bit cyclic ADCs with programmable gain amplifiers, two operational amplifiers, four analog comparators, and one 12-bit DAC. Communication interfaces consist of two high-speed queued SCI modules, one queued SPI module, and two LPI2C modules supporting Full PMBus. The unit operates on a single 3.3 V supply within a voltage range of 2.7 V to 3.6 V and is housed in a 64-pin LQFP package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the required operating voltage range of 2.7 V to 3.6 V. Confirm that the 64-pin LQFP package dimensions meet the PCB layout requirements. Check for any recent revisions to the MC56F81XXXL data sheet that may impact peripheral configurations or electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this component when a unified DSP and MCU architecture is required for real-time control tasks. The MC56F81768LVLH is suitable for applications needing high-speed analog-to-digital conversion with programmable gain. Consider the available communication interfaces, such as LIN slave support via QSCI and PMBus support via LPI2C, for system integration needs. Evaluate the thermal performance if operating near the upper limit of the -40°C to 105°C ambient temperature range.

Digital Signal Processor Dsp Part Context

This device belongs to the MC56F81xxxL family of digital signal controllers based on the 56800EX core. The family combines DSP processing power with MCU functionality, featuring flexible peripheral sets. Other members in this series vary primarily in memory size and pin count, such as the 48-pin variants with reduced I/O counts. The L-series designation typically indicates specific package and temperature grade options within the broader MC56F81xxx product line.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include other MC56F81xxxL variants with different memory sizes or pin counts, provided the functional requirements are met. Cross-family migration to the MC56F80xxx or MC56F82xxx series requires significant architectural changes due to differences in core types (56800EF vs. 56800EX). Verify pinout compatibility and peripheral availability before considering alternative part numbers.
