MC56F81646VLFR

Digital Signal Processor Dsp Overview

The MC56F81646VLFR is a digital signal controller from the NXP MC56F81xxx family, built on the 32-bit 56800EX core. It operates at up to 100 MHz in fast mode and provides 64 KB of Flash memory and 12 KB of RAM. The device features two 12-bit ADCs, two operational amplifiers, four analog comparators with integrated 8-bit DAC references, and one 12-bit DAC. Communication interfaces include two QSCI modules with LIN slave functionality, one QSPI module, and two LPI2C modules supporting Full PMBus. It utilizes a 48-pin LQFP package and supports a supply voltage range of 2.7 V to 3.6 V.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature grade. Ensure compatibility with the required operating voltage range of 2.7 V to 3.6 V. Check for moisture sensitivity levels and recommended storage conditions prior to assembly.

Digital Signal Processor Dsp Selection Notes

Select this component when a unified DSP and MCU architecture is required for complex control algorithms. The 56800EX core offers efficient C compilation support. Consider the available GPIO count and peripheral set, such as the presence of quadrature decoders or specific PWM channels, relative to system requirements.

Digital Signal Processor Dsp Part Context

This part belongs to the MC56F81xxxL series, which integrates the 56800EX core. It shares architectural similarities with other members like the MC56F81768 but differs in memory size and pin count. The 'VLFR' suffix typically denotes the 48-pin LQFP package and reel packaging format.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include MC56F81746VLFR (64 KB Flash, 12 KB RAM) or MC56F81668VLFR (64 KB Flash, 20 KB RAM), provided the pinout and peripheral configuration match the design constraints.
