MC56F81646VLF

Digital Signal Processor Dsp Overview

The MC56F81646VLF is a digital signal controller from the NXP MC56F81xxx family, built on the 32-bit 56800EX core. It operates at a maximum clock frequency of 100 MHz and features 64 kB of Flash memory and 12 kB of data RAM. The device utilizes a single 3.3 V supply (2.7 V to 3.6 V range) and is housed in a 48-pin LQFP package. Key peripherals include two 12-bit ADCs, an eFlexPWM module with NanoEdge resolution, and communication interfaces such as QSCI, QSPI, and LPI2C.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the component meets the required RoHS compliance standards for the intended deployment environment. Ensure that the 48-pin LQFP package dimensions align with the target PCB layout specifications before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select this model when a balance of DSP processing power and MCU flexibility is required within a 48-pin footprint. The 64 kB Flash capacity suits moderate code complexity, while the 100 MHz speed supports real-time control loops. Consider the available GPIO count and peripheral set, such as the presence of quadrature decoders or specific timer configurations, relative to system requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the MC56F81xxx series of digital signal controllers. The family shares the common 56800EX core architecture but varies in memory sizes, peripheral availability, and package options. The MC56F81646 variant specifically denotes the 64 kB Flash and 12 kB RAM configuration within the 48-pin LQFP form factor.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include other MC56F81xxx variants with compatible pinouts, such as MC56F81746VLF or MC56F81648VLF, provided memory and peripheral differences are acceptable. Cross-family migration requires careful evaluation of core instruction set compatibility and peripheral register mappings.
