MC56F81666LVLF

Digital Signal Processor Dsp Overview

The MC56F81666LVLF is a digital signal controller from the NXP MC56F81xxxL family, built on the 32-bit 56800EX core. It delivers up to 100 MIPS at a 100 MHz core frequency in fast mode. The device integrates 128 KB of flash memory and 20 KB of data/program RAM. Key peripherals include two 12-bit cyclic ADCs with programmable gain amplifiers, one 12-bit DAC, two operational amplifiers, and four analog comparators. It features an eFlexPWM module with NanoEdge resolution, multiple communication interfaces including LPI2C and QSCI, and comprehensive security modules such as CRC and watchdog timers. The unit operates on a single 2.7 V to 3.6 V supply within the -40°C to 105°C ambient temperature range.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the official NXP MC56F81XXXL datasheet to confirm package type, temperature grade, and production status. Ensure compatibility with required voltage levels and interface configurations before integration. Cross-reference part numbers with current distributor listings for availability and lead times.

Digital Signal Processor Dsp Selection Notes

Select this model when 128 KB of program memory and 20 KB of RAM are required alongside high-resolution PWM capabilities. The dual 12-bit ADCs with programmable gain make it suitable for precision analog sensing tasks. Verify that the 64-pin or 48-pin LQFP package fits the target PCB layout constraints and thermal requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the MC56F81xxxL series, which shares the same 56800EX core architecture but varies in memory size and peripheral count. The MC56F81666 variant specifically provides the maximum memory configuration (128 KB Flash) within the 64-pin footprint options, distinguishing it from lower-capacity models like the MC56F81646.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include other MC56F81xxxL variants with compatible pinouts and core functionality. Verify memory requirements and peripheral availability when selecting alternatives such as the MC56F81766 or MC56F81746.
